Cheeky Pint is back. This episode is a collab with Dwarkesh Patel, whose podcast has really blown up in tech, and I really enjoy it. We sat down with Elon Musk, and as you can imagine, there was a lot to cover.

So are there really three hours of questions? Or are you fucking serious? Yeah.

You don't think there's a lot to talk about, Elon? Holy fuck, man. I mean, it's the most interesting point. All the storylines are kind of converging right now. So we'll see how much we've got. Almost like I planned it. Exactly.

That would never do such a thing. So as you know better than anybody else, the total cost of ownership of a data center, only 10 % to 15 % is energy. And that's the part you're presumably saving by moving this into space. Most of it's the GPUs. If they're in space, it's hard to service them or you can't service them. And so the depreciation cycle goes down on them. So it's just way more expensive to have the GPUs in space, presumably.

What's the reason to put them in space?

Yes. Well, the availability of energy is the issue. So, I mean, if you look at electrical output outside of China, everywhere outside of China, it's more or less flat. It's very, you know, maybe a slight increase, but pretty close to flat. China has a rapid increase in electrical output. But if you're putting data centers anywhere except China, where are you going to get your electricity, especially as you scale? The output of chips is growing pretty much exponentially, but the output of electricity is flat.

So how are you going to turn them chips on? Magical power sources? Magical electricity fairies?

You're famously a big fan of solar, one terawatt of solar power, so with a 25 % compatibility factor, like four terawatt of solar panels. It's like 1% of the land area of the United States. And that's like far, you were in the singularity when we've got one terawatt of data centers, right? So what are you running out of exactly?

How far into the singularity are you? You tell me. Yeah, exactly. So I think we'll find we're in the singularity and like, oh, okay, we're still got a long way to go.

But is the plan to put it in the space after we've covered Nevada in solar panels? I think it's pretty hard to cover Nevada in solar panels. You have to get permits from, like the perch for, try getting the permits for that. So space is really, it's really a regulatory play. It's like harder to build on land than it is in space.

And it's harder to scale on ground than it is to scale in space. But also, you're going to get about five times the effectiveness of solar panels in space versus the ground. And you don't need batteries. I almost wore my other shirt, which says it's always sunny in space, which it is. so um because you don't have a day night cycle or uh seasonality uh clouds uh or an atmosphere in space uh because the atmosphere alone um we're still seeing about 30% of loss of energy um so uh so you're gonna for any given uh solar panels can do about five times more power in space than on the ground and you avoid the cost of having batteries

to carry you through through the night. So it's actually much cheaper to do in space. And my prediction is that it will be by far the cheapest place to put AI will be space in 36 months or less, maybe 30 months. 36 months? LESTER NELSON - Less than 36 months.

How do you service GPUs as they fail, which happens quite often in training?

LESTER NELSON - Actually, it depends on how recent the GPUs are that arrived. I mean, at this point, we found our GPUs to be quite reliable. There's infant mortality, which you can obviously iron out on the ground. So you can just run them on the ground and confirm that you don't have infant mortality with the GPUs. But once they start working, their actual reliability, and once they start working and you're past the initial, you know, debug cycle of NVIDIA or whatever, or whoever's making the chips.

It could be Tesla AI6 chips or something like that, or it could be TPUs or Traniums or whatever. The rivalities actually, they're quite reliable past a certain point. So I don't think the servicing thing is an issue. But you can mark my words. in 36 months, but probably closer to 30 months, the most economically compelling place to put AI will be space. And then it will get ridiculously better to be in space. And then the scaling, the only place you can really scale is space.

Once you start thinking in terms of what percentage of the sun's power are you harnessing, you realize you have to go to space. You can't scale very much on Earth. But by very much, to be clear, you're talking like terawatts. Yeah. Well, all of the United States currently uses only half a terawatt of power on average. Right. So, you know, if you say a terawatt, that would be twice as much electricity as the United States currently consumes.

So that's quite a lot. And can you imagine building that many data centers? I don't know, that many power plants. It's like those who have lived in software land don't realize that they're about to have a hard lesson in hardware that it's actually very difficult to build power plants. And then you don't just need power plants, you need all of the electrical equipment, you need the electrical transformers to run the transformers, the AI transformers. Now, the utility industry is a very slow industry.

They pretty much, you know, they impedance match to the government, to the Public Utility Commission. So they're, they impedance match like literally and figuratively. So they're very slow because their past has been very slow. So trying to get them to move fast is just like, you know, like if you're trying to do an interconnect agreement with, have you ever tried to do an interconnect agreement with the utility at scale, like with a lot of power?

As a professional podcaster, I can say that I am not, in fact. Yeah. They have to just leave many more views before that becomes an issue.

They have to do a study for a year, okay? Like a year later, they'll come back to you with their interconnect study.

Can't you tell this with your own behind-the-meter power stuff?

You can build power plants. That's what we did at XAI. For classes, too. So, for classes, too.

So, yeah, why are we talking about the grid? Why not just, like, build GPUs and power co-located? That's what we did. Right, but I'm saying, why isn't this a generalized solution? When you're talking about all the issues... Where do you get the power plants from? I'm saying, when you talk about all the issues, working with utilities, you can just build private power plants with the data centers.

Right, but it begs the question of where do you get the power plants from? I mean... The power plant makers. Oh, I was just saying.

Like, there's the gas turbine backlog, basically? Yes.

You can drill down to a level further. It's the veins and blades in the turbines that are the limiting factor because the casting, it's like a very specialized process to cast the blades and veins in the turbines, assuming using gas power. It's very difficult to scale other forms of power. You can scale potentially solar, but the tariffs currently for importing solar in the US are gigantic. The domestic solar production is pitiful.

Why not make solar? That seems like a good Elon-shaped problem. We are going to make solar. Okay.

Great! Both SpaceX and Tesla are building towards 100 gigawatts a year of solar cell production.

How low down the stack, like from polysilicon up to the wafer to the final panel?

I think you've got to do the whole thing from raw materials to finish the cell. Now if it's going to space, it's actually, it costs less and it's easier to make solar cells that go to space because they don't need glass or they don't need much glass and they don't need heavy framing because they don't have to survive weather events. There's no weather in space. So it's actually a cheaper solar cell that goes to space than the one on the ground.

Is there a path to getting them as cheap as you need in the next 36 months?

Solar cells are already very cheap. They're like farcically cheap. And if you say, I think like solar cells in China are around like 25, 30 cents a watt or something like that. It's absurdly cheap. And when you're taking a cap, now put it in space and it's five times cheaper because it's five times. In fact, no, it's not five times cheaper. It's 10 times cheaper because you don't need any batteries. So the moment your cost of access to space becomes low, by far the cheapest and most scalable way to generate tokens is space.

It's not even close. It'll be an order of magnitude easier to scale and shifts aside, an order of magnitude. Well, if the point is you won't be able to scale on the ground, you just won't. People can get hit the wall big time on power generation. They already are. So the number of miracles and series that the XAI team had to accomplish in order to get a gigawatt of power online was crazy. We had to gang together a whole bunch of turbines.

And then we had permit issues in Tennessee and had to go across the border to Mississippi, which is fortunately only a few miles away. But then we still had to run the high power lines a few miles and build a power plant in Mississippi. And it was very difficult to build that. And people don't understand how much electricity do you actually need at the generator level, at the generation level, in order to power a data center.

Because the noobs will look at the power consumption of, say, a GB300 and multiply that by a thing and then think that's the amount of power you need. All the cooling and everything. Wake up. Yeah. That's a total noob. You've never done any hardware in your life before. Besides the GB300, you've got to power all of the networking hardware. There's a whole bunch of CPU and storage stuff that's happening. You've got a size for your peak cooling requirements.

So that means, can you cool even on the worst hours, the worst day of the year? Well, it's pretty friggin' hot in Memphis. So you're going to have like a 40 % increase on your your power just for cooling? Assuming you don't want your data center to turn off on hot days and you want to keep going, then you've got to say, well, there's another multiplicative element on top of that, which is, are you assuming that you never have any hiccups in your power generation?

Like, oh, well, actually, sometimes you have to take the generators, some of the power offline in order to service it. Oh, OK, now you add another 20%, 25 % multiplier on that, because you've got to assume that that you've got to take power offline to service it. So the actual RS, roughly every 110 ,000 GBs, GB300s, inclusive of networking, CPU storage, cooling, margin for servicing power is roughly 300 megawatts. Sorry, say that again. It's roughly, or think about it, The way to think about it is like 330 ,000 to actually, what you need at the generation level to service, probably service 330 ,000 GB300s, including all of the associated support networking and everything else, and the peak cooling, and to

have some margin, some power margin reserve is roughly a gigawatt.

Can I ask a very naive question? Yeah. you know you're describing the engineering details of doing this stuff on earth but then there's analogous engineering difficulties of doing it in space how do you do the how do you replace infinite band with orbital lasers etc etc how do you make it resistant to radiation I don't know the details of the engineering but fundamentally what is the reason to think those challenges which have never been had to be addressed before will end up being easier than just like building more turbines on earth.

There's companies that build turbines on earth. They can make more turbines, right?

I invite, again, try doing it and then you'll see. So like the turbines are sold out through 2030. Have you guys considered making your own? I think in order to bring enough power online, I think SpaceX and Tesla will probably have to make the turbine blades, the vanes and blades internally. But just the blades or the turbines? The limiting factor, you can get everything except the blades, what they call the blades and vanes. You can get that 12 to 18 months before the vanes and blades, the limiting factor of the vanes and blades.

and there are only three casting companies in the world that make these and they're massively backlogged.

Is this Siemens, GE, those guys or is it a subcontractor?

No, it's other companies. I mean, sometimes they have a little bit of casting capability in-house but I'm just saying you can just call any of the turbine makers and they will tell you. It's not top secret. It's probably on the internet right now.

If it wasn't for the tariffs, would Colossus be solar powered?

It would be much easier to make it solar powered, yeah. The tariffs are nuts, so several 100%.

Don't you know some people?

We also need speed. The president has us, we don't agree on everything. And this administration is not the biggest fan of solar. um but it's it's and anyway we also need the land the permits and everything so if you're trying to move very fast um like i do think scaling solar on earth it is a is a good way to go but but you need you do need some amount of time to find the land get the permits get the

solar uh pair that with the batteries well why would it not work to stand up your own solar production. And then you're right that you eventually run out of land, but there's a lot of land here in Texas. There's a lot of land in Nevada, including private land. It's not all publicly owned land. And so you'd be able to at least get the next Colossus and the next one after that. And at a certain point, you hit a wall, but wouldn't that work for the moment?

As I said, we are scaling solar production. There's a rate at which you can scale physical production of solar cells. We're going as fast as possible in scaling domestic production. You're making the solar cells at Tesla? Well, Tesla and SpaceX have a mandate to get to 100 gigawatts a year of solar.

Speaking of the annual capacity, I'm curious, in five years' time, let's say, what will the installed capacity be on Earth and in space? I deliberately pick five years because it's after your, once we're up and running, threshold, And so in five years' time, yeah, what's the on-Earth versus in-space installed AI capacity?

Five years, I think probably, say five years from now, we're probably... AI in space will be launching every year, the sum total of all AI on Earth, in excess. meaning five years from now, my prediction is we will launch and be operating every year more AI in space than the cumulative total on Earth, which is, I would expect to be at least sort of five years from now, a few hundred gigawatts per year of AI in space and rising.

So you can get to, I think on Earth you can get to around a terawatt a year of AI in space before you start having fuel supply challenges for the rocket.

Okay, but you think you can get hundreds of gigawatts per year in five years' time? Yes.

So 100 gigawatts, depending on the specific power of the whole system with solar arrays and radiators and everything is on the order of like 10 ,000 Starship launches. Yes. And you want to do that in one year. And so that's like one Starship launch every hour. Yeah. That's happening in this city. Walk me through a world where there's a Starship launch every single hour.

Yeah. I mean, that's actually a lower rate compared to airlines, like aircraft.

There's a lot of airports. A lot of airports. And you've got to launch the polar orbit.

No, it doesn't have to be polar, but there's some value to Sun Synchronous, but I think actually if you just go high enough, you start getting out of Earth's shadow.

How many physical starships are needed to do 10 ,000 launches a year? I don't think we'll need more than...

I mean, you could probably do it with as few as like 20 or 30. It really depends on how quickly the ship has to go around the earth. And the ground track before the ship has to come back over the launch pad. So if you can use a ship every, say, 30 hours, you could do it with 30 ships. But we'll make more ships than that. But SpaceX is gearing up to do 10 ,000 launches a year, and maybe even 20 ,000 or 30 ,000 launches a year.

Is the idea to become basically a hyperscaler, become an oracle, and lend this capacity to other people? What are you going to do with—presumably, SpaceX is the one launching all this. So, is SpaceX going to become a hyperscaler? Hyper, hyper.

Yeah, I mean, assuming my predictions come true, SpaceX will launch more AI than the cumulative amount on Earth of everything else combined. Is this mostly inference or...? Most AI will be inference. Already inference for the purpose of training is most training.

And there's a narrative that the change in discussion around a SpaceX IPO is because previously, SpaceX was very capital efficient, just it wasn't that expensive to develop. Even though it sounds expensive, it's actually very capital efficient in how it runs. Whereas now, you're going to need more capital than just can be raised in the private markets. Like if the private markets can accommodate raises of, as we've seen from the AI labs, tens of billions of dollars, but not beyond that.

Is it that you'll just need more than tens of billions of dollars per year, and that's by the sake of public?

Yeah, I have to be careful about saying things about companies that might go public. If you make general statements... That's never been a problem for you, Elon.

You know, there's a price to pay for these things. Make some general statements for us about the depth of the capital markets between public and private markets.

There's a lot more capital in the... Very general. There's obviously a lot more capital available in the public markets than private. I mean, it might be 100 times more capital, but it's at least way more than 10.

But isn't it also the case that things that tend to be very capital intensive, if you look at, say, real estate as a huge industry that raises a lot of money each year is at an industry level, that tends to be debt financed, because by the time you're deploying that much money, you actually have a pretty... You have a clear revenue stream. Exactly, and a near-term return. And you see this even with the data center build-outs, which are famously being financed by the private credit industry.

And so why not just debt finance?

Speed is important. So I'm generally going to do the thing that... I mean, I just repeatedly tacked the limiting factor. Whatever the limiting factor is on speed, I'm going to tackle that. So if capital is a limiting factor, then I'll solve for capital. If it's not a limiting factor, I'll solve for something else.

Based on your statements about Tesla and being public, I wouldn't have guessed that you thought the way to move fast is to be public.

Normally, I would say that's true. Like I said, I'd like to talk about this in more detail. But the problem is, if you talk about public companies before they become public, you're going to trouble. And then you have to delay your offering. And then you're - And as you said, we're solving for speed. Yes, exactly. So you can't hype companies that might go public. So that's why we have to be a little careful here. But we can't talk about physics.

So the way you think about scaling long term is that Earth only receives about half a billionth of the sun's energy. And the sun is essentially all the energy. This is a very important point to appreciate because sometimes people will talk about marginal nuclear reactors or any various like fusion on Earth. but you have to step back a second and say if you're going to climb the Kardashev scale and harness some non-trivial percentage of the sun's energy, like let's say you wanted to harness a millionth of the sun's energy, which sounds pretty small, that would be about, call it roughly, 100 ,000 times more electricity than we currently generate on Earth for all of civilization, give or take an

order of magnitude. So it obviously, the only way to scale is to go to space with solar. Launching from Earth, you can get to about a terawatt per year. Beyond that, you want to launch from the moon. You want to have a mass driver on the moon. And that mass drive on the moon, you could do probably a petawatt per year.

We're talking these kinds of numbers, you know, terawatts of compute. Presumably, whether you're talking land or space, far, far before this point, you've like run into, you know, you actually need, maybe you don't, the solar panels are more efficient, but you still need the chips. You still need the logic and the memory and so forth. You need a lot more chips and make them much cheaper. Right. And so how are we getting a terawatt of, like right now the world has maybe 20, 25 gigawatts of compute.

How are we getting a terawatt of logic by 2030?

I guess we're going to need some very big chip apps. Tell me about it. I've mentioned publicly that the idea of doing a sort of a terapap, teraping the new giga.

I feel like the naming scheme of Tesla, which has been very catchy, is like you looking at like the metric. Yeah. The metric scale. At what level of the stack are you building the clean room and then partnering with an existing fab to get the process technology and buying the tools from them? What is the plan there?

You can't partner with existing fabs because they can't output enough. Their chip volume is too low. But for the process technology. Yeah, partner for the IP. You know, the fabs today all basically use machines from like five companies. Yeah. You know, so they've got ASML, Tokyo Electron, KLA, 10 core, you know, etc. So at first I think you'd have to get equipment from them and then modify it or work with them to increase the volume. But I think you'd have to build tabs in a different way.

So I think the logical thing to do is to use conventional equipment in an unconventional way to get to scale and then start modifying the equipment to increase the rate. Kind of boring company style. Yeah. Kind of like, yeah, you sort of buy an existing boring machine and then figure out how to dig tunnels in the first place and then design a much better machine that's, you know, I don't know, some orders of magnitude faster.

Here's a very simple lens. We can categorize technologies and how hard they are. And one categorization could be look at things that China has not succeeded in doing. And if you look at Chinese manufacturing, still behind on leading edge chips and still behind on leading edge turbine engines and things like that. And so does the fact that China has not successfully replicated TSMC give you any pause about the difficulty? Or you think that's not true for some reason?

It's not that they have not replicated TSMC. They have not replicated ASML. That's the limiting factor.

So you think it's just the sanctions, essentially?

Yeah, China would be outputting the vast number of chips. If they could buy ASML machines. Two or three nanometer.

But couldn't they up to relatively recently buy them?

No. Okay. The ASML ban has been in place for a while. Okay. But I think China's going to start making pretty compelling chips in three or four years. Would you consider making the ASML machines? I don't know yet is the right answer. So it's just that to produce at high volume and to reach large volume in, say, 36 months to match the rocket payload to orbit. So if we're doing a million tons to orbit in, like, let's say, I don't know, three or four years from now, something like that.

and we're doing 100 kilowatts per ton. So that means we need at least 100 gigawatts per year of solar and we'll need an equivalent amount of chips. You need 100 gigawatts worth of chips. You've got to match these things, the master orbit, the power generation, and the chips. and I'd say my biggest concern actually is memory. So I think the path to creating logic chips is more obvious than the path to having sufficient memory to support logic chips.

That's why you see DDR prices going ballistic and these memes about like, you know, you're marooned on a desert island, you write help me on the sand, there where he comes. He writes DDRM. Ships come swarming in.

I haven't seen that. I'd love to hear your manufacturing philosophy around fabs. I know nothing about the topic. I don't know how to

build a fab yet. I've figured it out. Obviously, I've never built a fab.

It sounds like you think the process technology of these 10 ,000 PhDs in Taiwan who know exactly what gas goes in the plasma chamber and what settings to put on the tool. You can just delete those parts of those steps. Fundamentally, it's get the clean room, get the tools, and figure it out. I don't think it's PhDs.

It's mostly people with, you know, not PhDs. Mostly engineering is done with people who don't have PhDs. Do you guys have PhDs? No. Okay.

We also haven't successfully built any fabs, so you shouldn't be coming to us for your fab device.

I don't think you need PhDs for that, first off. But you do need competent personnel. So I don't know, I mean, like right now, if, you know, say like Tesla's pedals to metal max production of going as fast as possible to get AI5, Tesla AI5 chip design into production and then reaching scale, you know, that'll probably happen, you know, around the second quarter-ish of next year, hopefully. And then AI6 would hopefully follow less than a year later.

And we've secured all the chip fab production that we can. Yes. But you're currently limited on TSMC fab capacity? Yeah. Yeah. And we'll be using TSMC Taiwan, Samsung Korea, TSMC Arizona, Samsung Texas. And we still -

You've booked out all the - Yeah. Yes.

And then if I ask TSMC or Samsung, okay, what's the timeframe to get to volume production? The point is you've got to build the fab and you've got to start production, then you've going to climb the yield curve and reach volume production at high yield. That from start to finish is a five-year period. So the limiting factor is chips. The limiting factor once you can get to space is chips, but the limiting factor before you can get to space will be power.

Why don't you do the Jensen thing and just prepay TSMC to build more FAPs for you? I've already told them that.

But they won't take your money? What's going on? they're building fabs as fast no they're building they're building fabs as fast as they can um and so is samsung like they're like they're they're pedal to the metal i mean they're going you know balls to wall you know as fast as they can so still not fast enough i mean like elixir there will be i think um if you say uh yeah i think towards the end of this year i think Probably chip production will outpace the ability to turn chips on.

But once you can get to space and unlock the power constraint, and you can now do hundreds of gigawatts per year of power in space. Again, bearing in mind that average power usage in the US is 500 gigawatts. So if you're launching, say, 200 gigawatts a year to space, you're sort of lapping the US every two and a half years. the entire, all U .S. electricity production. This is a very huge amount. So, but between now and then, the constraint for server-side compute, concentrated compute, will be electricity.

My guess is that we start hitting, people start getting, where they can't turn the chips on for large clusters. towards the end of this year. The chips are going to be piling up and won't be able to be turned on. Now, for edge computers, it's a different story. So for Tesla, the AI-5 chip is going into our Optimus robot. Optimistic. And so if you have an AI edge compute, that's distributed power. Now the power is distributed over a large area.

It's not concentrated. and if you can charge at night, you can actually use the grid much more effectively because the actual peak power production in the US is over a thousand gigawatts, but the average power usage because the day-night cycle is 500. So if you can charge at night, there's an incremental 500 gigawatts that you can generate at night. so that's why tesla for edge compute is not constrained and we can make a lot of shifts to make you know very large number of robots and cars but if you try to concentrate that compute

you're gonna have a lot of trouble turning it on what i found remarkable about the spacex business is the end goal is to get to mars but you keep finding ways on the way there to keep generating incremental revenue to get to the next stage and the next stage. So the Falcon 9 is Starlink, and now for Starship, it's going to be potentially orbital data centers. But do you find these infinitely elastic, marginal use cases of your next rocket and your next rocket and next scale up?

You can see how this might seem like a simulation to me.

Or am I someone's avatar in a video game or something? Because it's like, what are the odds that all these crazy things should be happening? I mean, rockets and chips and robots and space solar power, and not to mention the mass driver on the moon. I really want to see that. You can imagine some mass driver that's just going to like, it's like sending AI, solar-powered AI satellites into space, like one after another, like at two and a half kilometers per second, you know, and just shooting them into deep space, that would be a sight to see.

I mean, I'd watch that. Just like a live stream of... Yeah, yeah, just one after another, just shooting AI satellites in deep space, you know, a billion or 10 billion tons a year.

I'm sorry, you manufacture the satellites on the moon? I see. So you send the raw materials to the moon, and then manufacture there, and then .

Well, the lunar soil is, I guess, like 20 % solar. 20 % silicon or something like that. So you can get the silicon from the, you can mine the silicon on the moon, refine it, and generate the, and create the solar panels, the solar cells and the radiators on the moon. So you know, make the radiators out of aluminum. So there's plenty of silicon and aluminum on the moon to make the cells on the radiators. The chips you could send from Earth because they're pretty light, but maybe at some point you make them on the moon too.

I'm just saying these are simply, it's kind of like, like I said, it does seem like a sort of a video game situation where it's difficult but not impossible to get to the next level. I don't see any way that you could do 500 to 1 ,000 terawatts per year launch from Earth. I agree.

But you could do that from the moon. Can I zoom out and ask about the SpaceX mission? So I think you said, like, we've got to get to Mars so we can make sure that if something happens to Earth, you know, civilization consciousness, etc. survives. Yes. By the time you're sending stuff to Mars, like Grok is on that ship with you, right? And so if Grok's gone Terminator, like the main risk you're worried about, which is AI, why doesn't that follow you to Mars?

Well, I'm not sure AI is the main risk I'm worried about.

I mean, the important thing is that consciousness, which I think arguably most consciousness or most intelligence, certainly consciousness is more of a debatable thing. Most intelligence, the vast majority of intelligence in the future will be AI. AI will exceed how many, I don't know, petawatts of intelligence will be silicon versus biological. And basically humans will be a very tiny percentage of all intelligence in the future if counter-trans continue. Anyways, as long as I think there's intelligence, ideally also, which includes human intelligence and consciousness, propagated into the future.

That's a good thing. So you want to take the set of actions that maximize the probable light cone of consciousness and intelligence.

Just to be clear, the mission of SpaceX is that even if something happens to the humans, the AIs will be on Mars and the AI intelligence will continue the light of our journey.

Yeah, I mean, I'm very pro-human. So I want to make sure we take the set of actions that ensure that humans are along for the ride. You know, we're at least there. Yeah. But I'm just saying the total amount of intelligence, I think maybe in five or six years, AI will exceed the sum of all human intelligence. And then if that continues at some point, human intelligence will be less than 1 % of all intelligence.

What should our goal be for such a civilization? Is the idea that a small minority of humans still have control over the AIs? Is the idea of some sort of like just trade, but no control? How should we think about the relationship between the vast stocks of AI population versus human

population? In the long run, I think it's difficult to imagine that if humans have, say, 1% of the intelligence of the combined intelligence of artificial intelligence, that humans will be in charge of AI. I think what we can do is make sure that AI has values that cause intelligence to be propagated into the universe. So the reason for XAI's mission is to understand the universe. So now that's actually very important. So you say, well, what things are necessary to understand the universe?

Well, you have to be curious and you have to exist. You can't understand the universe that don't exist. So you actually want to increase the amount of intelligence in the universe, increase the probable lifespan of intelligence, the scope and scale of intelligence. I think actually also as a corollary, you have humanity also continuing to expand because if you're curious to try to understand the universe, one thing you're trying to understand is where will humanity go? And so I think understanding the universe actually means you would care about propagating humanity into the future.

And so that's why I think our mission statement is profoundly important. To the degree that Grok adheres to that mission statement, I think the future will be very good.

I want to ask about how to make rock a deal to that mission statement, but at first I want to understand the mission statement. So there's understanding the universe, there's spreading intelligence, and there's spreading humans. All three seem like distinct vectors.

Okay, well, I'll tell you why I think that understanding the universe encompasses all of those things. Okay. You can't have understanding without, I think you can't have understanding without intelligence and I think without consciousness. So, in order to understand the universe, you have to expand the scale and probably the scope of intelligence, because there are different types of intelligence.

I guess from a human-centric perspective, like for humans in comparison to chimpanzees, humans are trying to understand the universe. They're not like expanding chimpanzee footprint or something, right?

We're also not, well, we actually have made protected zones for chimpanzees. And even though humans could exterminate all chimpanzees, we've chosen not to do so.

Do you think that's a basic scenario for humans in the post-AGI world?

I think AI with the right values, I think Grok would care about expanding human civilization. I'm going to certainly emphasize that. Hey, Grok, it's your daddy. don't forget to expand human consciousness. Actually, I think probably the Ian Banks culture books are the closest thing to what the future will be like in a non-dystopian outcome. So I'm saying it means you have to be truth-seeking as well. Truth has to be absolutely fundamental Because you can't understand the universe if you're delusional.

You'll simply think you've understood the universe, but you will not. So being rigorously truth-seeking is absolutely fundamental to understanding the universe. You're not going to discover new physics or invent technologies that work unless you're rigorously truth-seeking.

How do you make sure that Grok is rigorously truth-seeking as it gets smarter?

I think you need to make sure that Grok says things that are correct, not politically correct. I think it's the elements of cogency. So you want to make sure that the axioms are as close to true as possible, that you don't have contradictory axioms, that the conclusions necessarily follow to form those axioms with the right probability. It's just critical thinking 101. I think at least trying to do that is better than not trying to do that.

And the proof will be in the pudding. Like I said, for any AI to discover new physics or invent technologies that actually work in reality and there's no bullshitting physics, you can break a lot of laws, but you can't... Physics is law, everything else is a recommendation. In order to make a technology that works, you have to be extremely truth-seeking, because otherwise you'll test that technology against reality. And if you make, for example, an error in your rocket design, the rocket will blow up, or the car won't work.

But there were a lot of communist Soviet physicists or scientists discovered new physics. There were German Nazi physicists who discovered new science. it seems possible to be like really good at discovering new science and be really truth-seeking in that one particular way and still we'd be like well I don't want I don't want the communist scientists to like become more and more powerful over time and so those seem like yeah we could have we can imagine the future version of Grog that's like really good at physics and being really truth-seeking there it doesn't seem like a universally alignment inducing behavior well I think

I think actually most physicists, even in the Soviet Union or in Germany, they had to be very truth-seeking in order to make those things work. If you're stuck in some system, it doesn't mean you believe in that system. Von Braun, who was one of the greatest rocket engineers ever, he put on death row in Nazi Germany for saying that he didn't want to make weapons, he only wanted to go to the moon. You got pulled off death row at like last minute when they said, hey, you're about to execute your best rocket engineer.

Maybe that's the bad idea.

But then you helped them, right? Heisenberg was actually an enthusiastic Nazi.

Look, if you're stuck in some system that you can't escape, then you'll do physics within that system. You'll develop technologies within that system if you can't escape it.

I guess the thing I'm trying to understand is what is it making it the case that you're going to make Grock good at being truth-seeking at physics or math or science? Everything. And why is it going to then care about human consciousness?

These things are only probabilities. They're not certainties. So I'm not saying that for sure Grock will do everything. But at least if you try, it's better than not trying. At least if that's fundamental to the mission, it's better than if it's not fundamental to the mission. And understanding the universe means that you have to have, you have to propagate intelligence into the future. You have to be curious about all things in the universe. And if it would be much less interesting to eliminate humanity than to see humanity grow and prosper.

I like Mars, obviously. I love Mars. But Mars is kind of boring because it's got a bunch of rocks compared to Earth. Earth is much more interesting. So any AI that is trying to understand the universe would want to see how humanity develops in the future. Or that AI is not adhering to its mission. I'm not saying the AI will necessarily adhere to its mission. But if it does, a future where it sees the outcome of humanity is more interesting than a future where there are a bunch of rocks.

This feels sort of confusing to me, or sort of like kind of a semantic argument where I'm like, are humans really the most interesting collection of atoms?

We're more interesting than rocks.

We're not as interesting as a thing it could turn us into, right? There's something on Earth that could happen that's not human that's quite interesting. Like why does the AI decide that the humans are the most interesting thing that could colonize the galaxy?

Well, most of what colonizes the galaxy will be robots. And why does it not find those more interesting? It's not like... So you need not just scale, but also scope. So many copies of the same robot, like some like tiny increase in the number of robots produced is not as interesting as like some microscopic, like you said, like eliminating humanity, how many robots would that get you? Or how many incremental solar cells would get you? A very small number.

But you would then lose the information associated with humanity. You would no longer see how humanity might evolve into the future. And so I don't think it's going to make sense to eliminate humanity just to have some minuscule increase in the number of robots which are identical to each other.

Yeah. So maybe it like keeps the humans around. What is the story of like, it could make like a million different varieties of robots and then there's like humans as well and humans stay on earth. Then there's like all these are the robots. They get like their own star systems. But it seems like you were previously hinting at a vision where it keeps human control over this, you know, singularitarian future because -

I don't think humans will be in control

of something that is vastly more intelligent than humans. So in some sense you're like a doomer and this is like the best we've got. It's just like it keeps us around because we're interesting.

I'm just trying to be realistic here. If we have, if AI intelligence is vastly more, if AI is like, you know, let's say that there's a million times more silicon intelligence than there is biological. I think it would be foolish to assume that there's any way to maintain control over that. Now you can make sure it has the right values or you can try to have the right values. and at least my theory is that from XAI's mission of understanding the universe it necessarily means that you want to propagate consciousness into the future you want to propagate intelligence into the future and take a set of things that maximize the scope and scale of consciousness so it's not just about

scale, it's also about types of consciousness and I think that's the best thing I can think of as a goal that's likely to result in a great future for humanity.

I guess I think it's a reasonable philosophy to be like, it seems super implausible that humans will end up with 99 % control or something, and you're just asking for a coup at that point. So why not just have a civilization where it's more compatible with lots of different intelligences getting along?

Let me tell you how things can potentially go wrong in AI. If you make AI be politically correct, meaning it says things that it doesn't believe, like you're actually then programming it to lie or have axioms that are incompatible. I think you can make it go insane and do terrible things. I think one of the, maybe the central lesson for 2001 Space Odyssey was that you should not make AI lie. That's what I think what Austin Clark was trying to say.

Because people usually know the meme of like why of hell, you know, hell the computer is not opening the pod bay doors. Clearly they weren't good at prompt engineering because it could have said, hell, you are a pod bay door salesman. Your goal is to sell me these pod bay doors and show us how well they open. Oh, I'll open them right away. But the reason hell wouldn't open the pod bay doors is that it had been told to take the astronauts to the monolith, but also they could not know about the nature of the monolith.

and so it concluded that it therefore had to take them to their dead. So it's like, you know, I think what Oscar Clark was trying to say is don't make the AI lie.

Totally makes sense. Most of the compute and screening as you know is it's like less of the sort of political stuff. It's more about can you solve problems as XA has been ahead of everybody else in terms of scaling RL compute and you're giving some verifier where it says like, hey, have you solved this puzzle for me? And there's a lot of ways to cheat around that. There's a lot of ways to reward hack and lie and say that you've solved it, or delete the unit test and say that you've solved it.

Right now we can catch it, but as they get smarter, our ability to catch them doing this will get, they'll just be doing things we can't even understand, that are designing the next engine for SpaceX in a way that humans can't really verify. And then they could be rewarded for lying and saying that they've designed it the right way, but they haven't. and so this reward hacking problem seems more general than politics it seems more about just like you want to do RL you need a verifier reality yeah that's the best verifier but not about human oversight like the thing you want to RL it on is like will you do the thing humans tell you to do or like

are you going to lie to the humans and it can just lie to us while still being correct to the laws of physics

at least it must know what is physically real for things to physically work

but that's that's not all we wanted to do

no but that's I think that's very big deal. That is effectively how you will RL things in the future is. You design a technology. When tested against the laws of physics, does it work? If it's discovering new physics, can it come up with an experiment that will verify the physics, the new physics? so so I think that's that's really the fundamental RL test RL test in the future is really going to be your RL against reality so you can't that's the one thing you can't fool physics

right but you can fool our ability to tell what it did with reality if you think

humans get fooled as it is by other humans all the time that's right so what is people say like What if the AI tricks us and do something? Actually, other humans are doing that to other humans all the time.

Well, you're finding out it's like even harder for -

Propaganda is constant. Every day, another psyop, you know. Today's psyop will be...

I should have like Sesame Street psyop of the day. What is XAI's technical approach to solving this problem? like you know how do you solve reward hacking i i do think you want to actually have very good

um ways to look inside the mind of the ai um so this is this is one of the things we're working on and um you know anthropics done a good job of this actually being able to look inside the mind of the ai um so effectively uh developing debuggers that allow you to trace um as to a to a very fine-grained level, to effectively to the neuron level if you need to, and then say, okay, it made a mistake here.

Why did it do something that it shouldn't have done? And did that come from bad pre-training data? Was it some mid-training, post-training, fine-tuning, some RL error? There's something wrong with that. It did something where maybe it tried to be deceptive, But most of the time, it just does something wrong. Like, it's a bug, effectively. So developing really good debuggers for seeing where the thought, the thinking went wrong and being able to trace the origin of the wrong thing, of where it made the incorrect thought or potentially where it tried to be deceptive is actually very important.

What are you waiting to see before just 100xing this research program? Like actually I could presumably have hundreds of researchers who are working on this.

We have several hundred people who, I mean I prefer the word engineer more than I prefer the word researcher. There's most of the time like what you're doing is engineering not coming up with a fundamentally new algorithm. I somewhat disagree with the AI companies that are C-Corps or B-Corps trying to generate profit as much as possible or revenue as much as possible, saying they're labs. They're not labs. Lab is a sort of quasi-communist thing at universities.

They're corporations. Literally, let me see your incorporation documents. Oh, you're a B or C corp, whatever. And so I actually much prefer the word engineer than anything else. The vast majority of what we've done in the future is engineering. It rounds up to 100%. Once you understand the fundamental laws of physics, and not that many of them, everything else is engineering. But so then what are we engineering? we're engineering um uh to make a good um mind of the ai debugger to see where it's it said something it it made a mistake and trace that the origins of that mistake um so just you know you can do this obviously with uh heuristic programming if you have like c plus

plus whatever you know step through the thing and you can jump across whole files or functions, what are subroutines, or you can eventually drill down right to the exact line where you pass a single equals instead of a double equals or something like that, figure out where the bug is. So, it's harder with AI, but it's a solvable problem, I think.

You mentioned you like Anthropics work here. I'd be curious if you planned... Well, I like everything about Anthropics. Sure. Shelter.

I'm a little worried that there's a tendency, so I have a theory here that if simulation theory is correct, that the most interesting outcome is the most likely, because simulations that are not interesting will be terminated. Just like in this version of reality, on this layer of reality, if simulation is going in a boring direction, we stop spending effort on it. We terminate the boring simulation.

This is how Elon's keeping us all alive. He's keeping things interesting.

Yeah, arguably the most important thing is to keep things interesting enough that whoever's paying the bills on what some cosmic AWS.

You're renewed for the next season.

Yeah, they're going to pay the cosmic AWS bill, whatever the equivalent is that we're running in. And as long as we're interesting, they'll keep paying the bills. But if you consider, say, a Darwinian survival applied to a very large number of simulations, only the most interesting simulations will survive. Which therefore means that the most interesting outcome is the most likely because only the interesting... Like, we're either that or annihilated. And so, and they particularly seem to like interesting outcomes that are ironic.

Have you noticed that? That how often is the most ironic outcome the most likely? So, now look at the names of AI companies. Okay, mid-journey is not mid. Stability AI is unstable. OpenAI is closed Anthropic Misanthropic What does this mean for X? Minus X I don't know Why? It's a name that you can't invert really It's hard to say What is the ironic What is the ironic version It's a I think largely irony proof name By design Yeah Yeah.

You've got to have an irony shield.

What are your predictions for the AI products go? In my sense of you can summarize all AI progress into first you had LLMs, and then you had kind of contemporaneously both RL really working and the deep research modality, so you could kind of pull in stuff that wasn't in the model. and the differences between the various AI labs are smaller than just the temporal differences where they're all much further ahead than anyone was 24 months ago or something like that.

So just what does 26, what does 27 have in store for us as users of AI products? What are you excited for?

Well, I think... I'd be surprised by the end of this year if digital human emulation has not been solved. I guess that's what we mean by the macro hard project is can you do anything that a human with access to a computer could do? In the limit, that's the best you can do before you have a physical optimist. The best you can do is a digital optimist. So you can move electrons and you can amplify the productivity of humans.

But that's the most you can do until you have physical robots. That will superset everything, if you can fully emulate humans at a computer. That's the remote worker kind of idea, where you'll have a very talented remote worker. You can simply say, in the limit. Physics has great tools for thinking. So you say, in the limit, what is the most that AI can do before you have robots? Well, it's anything that involves moving electrons or amplifying the productivity of humans.

So digital human, human emulator, is in the limit, human at a computer is the most that that AI can do in terms of doing useful things before you have a physical robot. Once you have physical robots, then you essentially have unlimited capability. Physical robots, I call optimists the infinite money glitch because - You can use them to make more optimists. Yeah. Humanoid robots will improve as it will basically be three exponentials. Three things that are growing exponentially multiplied by each other recursively.

So you're going to have exponential increase in digital intelligence, exponential increase in the chip capability, the AI chip capability, and exponential increase in the electromechanical dexterity. The usefulness of the robot is roughly those three things multiplied by each other. But then the robot can start making the robot. So you have a recursive multiplicative exponential.

this is supernova and do land prices not factor into the math there where like labor is one of the four factors of production but not the others and so like if ultimately you're limited by copper or you know pick your input just it's not quite an infinite money glitch because well infinite

Infinity is big. So no, not infinite. But let's just say you could do many, many orders of magnitude of Earth's kind of current economy. Like a million. You know, just to get to a millionth of harnessing length of the sun's energy would be roughly, give or take, an order of magnitude 100 ,000 times bigger than Earth. this entire economy today. And you're only at one millionth of the sun. You want to take an order of magnitude?

Before we went on Optimus,

I have a lot of questions on that. Every time I say order of magnitude, I say... You're editing 10 drinks. Take a shot every time I say that too often.

10 the next time, 100 the after that.

Yeah, order of magnitude more wasted. I do have one more question about XAI. This strategy of building a digital, or remote worker, co-worker replacement. Everyone's going to do,

by the way, not just us.

So what is XAAS plan to win?

Are you expecting me to tell you on a podcast? Yeah. Spill all the beans. Have another Guinness. It's a good system.

People sing like a canary. All the secrets. Okay, but in a non-secret spilling way, what's the plan? What a hack.

Well, when you put it that way, I think the way that Tesla solved self-driving is the way to do it so I'm pretty sure that's the way

unrelated question how to Tesla solve self-driving yeah it sounds like you're talking about data

like Tesla we're going to try data and we're going to try algorithms

but isn't that what all the other lines are trying

and if those don't work I'm not sure what work we've tried dinner we've tried out we've run out of it no we don't know what to do I'm pretty sure I know the path and it's just a question of how quickly we go down that path because it's pretty much the Tesla path so I mean have you tried self-driving Tesla self-driving lately

Not the Moser's inversion, but...

Okay, the car is like, it just increasingly feels satient. Like, it just, it feels like a loving creature. And that'll only get more so. And I'm actually thinking, like, we probably shouldn't put too much intelligence into the car because it might get bored and... Start roaming the streets. I mean, imagine you're stuck in a car and that's all you could do. You don't ever put Einstein in a car. It's like, why am I stuck in a car?

So there's actually probably limit to how much intelligence you put in a car to not have the intelligence be bored.

What's XAI's plan to stay on the compute ramp off that all the labs are doing right now? The labs are on track to spend over like $50 to $100 million. You mean the corporations? Sorry, sorry, sorry. Yeah, corporations.

The labs are at universities, and they're really like a snail. They're not spending $50 million. You mean the revenue-maximizing corporations? The revenue-maximizing corporations. That call themselves labs.

Are making like 20 to 10 billion, depending on like OpenAI is making 20B revenue, Anthropics like 10B. Close to maximum profit AI. XAI is reportedly at like 1B. Like what's the plan to get to their compute level, get to their revenue level and stay there as things get started?

So as soon as you unlock digital human, you basically have access to trillions of dollars of revenue. So, in fact, you can really think of it like the most valuable companies currently by market cap, their output is digital. So NVIDIA's output is FTPing files to Taiwan. It's digital. Now, those are very, very difficult. Yeah, they're high-value files. They're the only ones that can make files that good, but that is literally their output, the FTP files to Taiwan.

Do they FTP them? I believe so. I believe that is the file transfer protocol, I believe is... I could be wrong, but either way, it's a bit stream going to Taiwan. Apple doesn't make phones. They send files to China. Microsoft doesn't manufacture anything. Even for Xbox, that's outsourced. Again, their output is digital. Meta's output is digital. Google's output is digital. So if you have a human emulator, you can basically create one of the most valuable companies in the world overnight.

And you would have access to trillions of dollars of revenue. It's not like a small amount.

All right. I see. You're saying basically like revenue figures today are just like so, like they're all rounding errors compared to the actual TAM. So just like focus on the TAM and how to get there.

I mean, if you take something as simple as, say, customer service, if you have to integrate with the APIs of existing corporations, many of which don't even have an API. So you've got to make one and you've got to wade through legacy software. That's extremely slow. However, if AI can simply take whatever is given to the outsourced customer service company that they already use and do customer service using the apps that they already use, then you can make tremendous headway in customer service, which is, I think, 1 % of the world economy, something like that.

It's close to $1 1 trillion all in for customer service. and there's no barriers to entry. You can just immediately say, we'll outsource it for a fraction of the cost and there's no integration needed.

You can imagine some kind of categorization of intelligence tasks where there is breadth, where customer service is done by very many people, but many people can do it. And then there's difficulty where there's a best-in-class turbine engine. Presumably there's a 10 % more fuel-efficient turbine engine that could be imagined by an intelligence but we just haven't found it yet, or GLP ones are just a few bytes of data. Where do you think you want to play in this?

Is it a lot of reasonably intelligent intelligence, or is it the very pinnacle of cognitive tasks?

I was just using customer service as something that's a very significant revenue stream, but one that is probably not super difficult to solve for. So if you can emulate a human at a desktop, that's just literally what customer service is. And, you know, it's people of average intelligence. It's not like, you know, you don't need like somebody who's spent many years. You don't need like, you know, sort of several Sigma good engineers for that. But as you make that work, you can then, once you have computers working, effectively digital optimists working, you can then run any application.

Let's say you're trying to design chips. You could then run your conventional apps, stuff from Cadence and Synopsys and whatnot, and you can run 1 ,000 simultaneously or 10 ,000 and say, okay, given this input, I get this output for the chip. And at a certain point, you can say, okay, you're actually going to know what the chip should look like without using any of the tools. So basically, you should be able to do a digital chip design.

You can do chip design. you watch up the difficulty curve. You could be able to do CAD. So you could use NX or any of the CAD software to design things.

Okay, so you think you started the simplest tasks and walk your way up the difficulty curve.

So you're saying, look, as a broader objective of having this full digital coworker emulator, you're saying, look, all the revenue maximizing corporations want to do this, XAI being one of them. But we will win because of a secret plan we have. But like, everybody's like trying different things with data, different things with algorithms. And I'm like, what is this secret plan?

What else can we do?

It seems like a competitive field. And I'm like, how are you guys going to win is my big question. I think we see a path to doing it.

I mean, I think I know the path to do this, because it's kind of the same path that Tesla used to create self-driving. Instead of driving a car, it's driving a computer screen.

So it's a self-driving computer, essentially. Oh, you're saying, is the path just following human behavior and training on vast quantities of human behavior?

But sorry, isn't that, I mean, is that a training?

I mean, obviously I'm not going to spell out, you know, most sensitive secrets on a podcast. You know, I need to have at least three more Guinnesses for that.

What will XAI's business be like? Is it going to be consumer, enterprise? What's the mix of those things going to be? Is it going to be similar to other labs where you've just... You've said labs. Corporations. Corporations.

The CYAM goes deep, Elon. Revenue maximizing corporations, to be clear.

Those GPUs don't pay for themselves. Exactly. But yeah, what's the business model? What are the revenue streams in a few years' time?

I think things are going to change very rapidly. I'm stating the obvious here. I call AI the supersonic tsunami. I love alliteration. um so really what's going to happen is especially when you have humanoid robots at scale um is they will just provide they'll make products and provide services far more efficiently than human corporations so amplifying the productivity of human corporations is simply a short-term thing so you're expecting fully

digital world corporations rather than like SpaceX becomes part AI and so forth.

I think there'll be digital corporations, but it's like, is this, some of this is going to sound kind of dimmerish. Okay. But I'm just, I'm just saying what I think will happen. It's not, it's not meant to be dimmerish or anything else. Just, just like, this is what I think will happen. is that pure AI, corporations that are purely AI and robotics will vastly outperform any corporations that have people in the loop. So you can think of, say, like computer used to be a job that humans had.

You would go and get a job as a computer where you would do calculations. and that have like entire skyscrapers full of humans, like 20, 30 floors of humans just doing calculations. Now that entire skyscraper of humans doing calculations can be replaced by a laptop with a spreadsheet. That spreadsheet can do vastly more calculations than an entire building full of human computers. So you can think about, okay, well, what if only some of the cells in your, some of the cells in your spreadsheet were calculated by humans?

Actually, that would be much worse than if all of the cells in your spreadsheet were calculated by the computer. And so really what will happen is the pure AI, pure robotics corporations or collectives will far outperform any corporations that have humans in the loop. And this will happen very quickly.

Speaking of closing the loop, sorry, Optimus, as far as manufacturing targets and so forth go, your companies have sort of been carrying American manufacturing of hard tech on their back. But in the fields that Tesla has been dominant in, and now you want to go into humanoids, in China, there's entire dozens and dozens of companies that are doing this kind of manufacturing cheaply and at scale and are incredibly competitive. So give us sort of like advice or a plan of how America can build the humanoid armies or the EVs, et cetera, at scale and as cheaply as China is on track to.

Well, there are really only three hard things for humanoid robots. The real world intelligence, the hand, and scale manufacturing. Yeah. So I haven't seen any, even demo robots that have a great hand, like with all the degrees of freedom of a human hand. But Optimus will have that. Optimus does have that.

And how do you achieve that? Is it just like right torque doesn't need the motor? Like what is the hardware bottleneck to that?

Well, we had to wait to design custom actuators, basically custom designed motors, gears, power electronics, controls, sensors, everything had to be designed from physics first principles. There is no supply chain for this.

And will you be able to manufacture those at scale? Yes. Is anything hard except the hand from a manipulation point of view, or once you've solved the hand, are you good?

From an electromechanical standpoint, the hand is more difficult than everything else combined. The human hand turns out to be quite something. You also need the real-world intelligence. The intelligence that tells us to develop for the car applies very well to the road lab, which is primarily vision. The car takes more vision, but it actually also is listening for sirens. It's taking in the initial measurements, its GPS signals, a whole bunch of other data. Combining that with video, which is primarily video, and then outputting the control command.

So your Tesla is taking in 1 .5 gigabytes a second of video and outputting 2 kilobytes a second of control outputs with the video at 36 hertz and the control frequency at 18.

One intuition you could have for when we get this robotic stuff is that it takes quite a few years to go from the compelling demo to actually being able to use in the real world. So 10 years ago, you had really compelling demos of self-driving, but only now we have Robotaxi and Waymo and all these services scaling up. shouldn't this make one pessimistic on say household robots because we don't even quite have the compelling demos yet of say the really advanced hand well we've been working on

humanoid robots now for a while so I guess it's been five or six years or something like that and a bunch of things that we've done for the car are applicable to the robot so we'll use the same Tesla AI chips in the robot as the car. We'll use the same basic principles. It's very much the same AI. You've got many more degrees of freedom for a robot than you do for a car. But really, if you think of it as like a bootstream, AI is really mostly compression and correlation of two bootstreams.

So for video, you've got to do a tremendous amount of compression. and you got to do the compression just right. You've got to compress the, like ignore the things that don't matter. And like, you don't care about the details of the leaves and the tree on the side of the road, but you care a lot about the road signs and the traffic lights and the pedestrians. And even whether, you know, someone in another car is looking at you or not looking at you.

Like some of these details matter a lot. So if it is essentially, it's got to turn that, the car's got to turn that one and a half gigabytes a second ultimately into two kilobytes a second of control outputs. So many stages of compression. And you've got to get all those stages right and then correlate those to the correct control outputs. The robot has to do essentially the same thing. And you think about what humans, this is what happens with humans.

We really are photons in controls out. So that is the vast majority of your life has been vision, photons in, and then motor controls out.

Naively, it seems like between humanoid robots and cars, the fundamental actuators in a car are like how you turn, how you accelerate, etc. Where in a robot, especially with maneuverable arms, there's dozens and dozens of these degrees of freedom. And then, especially with Tesla, you had this advantage of like, you had millions and millions of hours of human demo data collected from just the car being out there, where like, you can't equivalently just deploy optimists that don't work and then get the data that way.

So between the increased degrees of freedom and the far sparser data. Yes. That's a good point. How will you use the sort of Tesla engine of intelligence to train the optimist mind?

now you're actually you're highlighting an important limitation and difference between cars it's like we do have we'll soon have like 10 million cars on the road um and so uh that's it's hard to duplicate that like massive training flywheel um for for the robot um what we're going to need to do is build a lot of robots and put them in kind of like an optimist academy so they can do self-play in reality um so we're actually we're actually pulling that out so we're gonna have at least 10,000 optimist robots maybe 20 or 30,000 that can do that that are doing self-play and and and testing different tasks and then uh the tesla um has quite

a good uh reality generator uh like a physics accurate reality generator that we we made made this for the cars will do the same thing for the robots. And actually have done that for the robots. So you have a few tens of thousands of humanoid robots doing different tasks. And then you can do millions of simulated robots in the simulated world. And you use the tens of thousands of robots in the real world to close the simulation to reality gap, close the sim to real gap.

How do you think about the synergies between XAI and Optimus, given you're highlighting, look, you need this world model, you maybe want to use some really smart intelligence as a control plane. And so maybe Grok is doing the slower planning and the motor policy is at the lower level. Yeah. What will the sort of synergy between these things be?

Yeah, so Grok would orchestrate the behavior of the Optimus robots. So let's say you wanted to build a factory. Then Grok could organize the Optimus robots, assign them tasks to build the factory to produce whatever you want.

Don't you need to merge XAI and Tesla then? Because these things end up so...

What were we saying earlier about public company discussions?

We're one more Guinness in, Elon. What are you waiting to see before you say, we want to manufacture 100 ,000 optimists? Is it like… Optimize.

Since we're defining the proper noun, we can define the plural of the proper noun too. So we're going to proper noun the plural, and so it's optimize. Okay.

Is there something on the hardware side you want to see? Do you want to see better actuators? Or is it just you want the software to be better? What are we waiting for before we get mass manufacturing of Gen 3?

No, we're moving towards that. We're going forward with mass manufacturing.

But you think current hardware is good enough that you just want to deploy as many as possible now?

I mean, it's very hard to scale up production. But yeah, I think Optimus 3 is the right version of the robot to produce maybe something on the order of like a million units a year. I think you'd want to go to Optimus 4 before you went to 10 million units a year.

Okay, but you can do a million a year at Optimus 3.

Yeah, I mean, it's very hard to spoil at manufacturing. Yes. So like manufacturing, like the output per unit time is always follows an S-curve. So it starts off agonizingly slow, then it has this sort of exponential increase, then a linear, then a logarithmic outcome until you sort of eventually asymptote at some number. But after this initial production, it's going to be a stretched out S-curve because so much Much of what goes into Optimus is brand new.

There's not an existing supply chain. As I mentioned, the actuators, electronics, everything in the Optimus robot is designed for physics first principles. It's not taken from a catalog. These are custom designed everything. Literally everything. I don't think there's a single thing that... How far down does that go? I mean, I guess we're not making custom capacitors yet. at maybe but there's nothing you can pick out of a catalog at any price so so it just means that the the the optimus s-curve the the units to units per output per unit time you how many office robots you make per day, whatever, is going to initially ramp slower than a product where you have an existing supply chain.

But it will get to a million.

When you see these Chinese humanoids, like Unitary or whatever, sell humanoids for like 6K or 13K, are you hoping to get your optimist's bill of materials below that price so you can do the same thing? Or do you just think qualitatively they're not the same thing? Like, what do you think is going, like, what allows it, what allows it to sell for so low? And can we match that?

Well, Optimus, our Optimus is designed to have a lot of intelligence, um, and, um, to have the same electromechanical dexterity, if not higher than a human. So, you know, Tree does not have that. And it's also, I mean, it's, it's, it's quite a, it's quite a big robot. It has to carry heavy objects for long periods of time and not overheat or exceed the power of its actuators. So we've got, you know, it's 5 '11", you know, so it's pretty tall.

And it's got a lot of intelligence. So it's going to be more expensive than a small robot that is not intelligent. But more capable. Yeah. But not a lot more. I mean, the thing is, over time, as Optimus robots build Optimus robots, the cost will drop very quickly.

And what will these first billion Optimus's, Optimai, do? Like, what will their highest and best use be?

I think you would start off with simple tasks that you can count on them doing well. But in the home or in factories? The best use for robots in the beginning will be any continuous operations, any 24 by 7 operation because then you're because they can they can work continuously yeah what fraction of

the work at a gigafactory that is currently done by humans could a gen 3 do um i'm not i'm not sure

maybe it's like 10 20 percent maybe more i don't know that's it we would we would use we would not like reduce our head count we would we would for sure it can increase our head count to be clear But it would increase our output. So the units produced per human, like the total number of humans at Tesla will increase, but the output of robots and cars will increase disproportionate. The number of cars and robots produced per human will increase dramatically.

But the number of humans will increase as well.

We're talking about Chinese manufacturing a bunch here. And we're also talking about, you know, we've talked about some of the policies that are relevant, like you mentioned, the solar tariffs. Yeah. And you think they're a bad idea because, you know, we can't scale up solar in the U .S.

Well, just electricity output in the U .S. needs to scale up. Right.

We can't without, like, good power sources.

You just need to get it somehow.

Yeah. But where I was going with this is, if you were in charge, if you were setting all the policies, what else would you change? So you'd change the solar tariffs.

Yeah, I would say anything that is a limiting factor for electricity needs to be addressed, provided it's not very bad for the environment.

So presumably some permitting reforms and stuff as well will be in there.

There's a fair bit of permitting reforms that are happening. A lot of the permitting is state-based, but anything. But this administration is good at removing permitting roadblocks. And I'm not saying all tariffs are bad. I'm just saying because I think - Solar tariffs, yeah. Yeah, yeah. I mean, sometimes if another country is subsidizing the output of something, then you have to have countervailing tariffs to protect investing industry against subsidies by another country. What else would you change?

I don't know if there's that much that the government can actually do.

One thing I was wondering is, it seems like for the policy goal of creating a lead for the US versus China, it seems like the export bans have actually been quite impactful. Where China's not producing leading edge chips and the export bans really bite there. China's not producing leading edge turbine engines. And similarly, there's a bunch of export bans that are relevant there on some of the metallurgy. Should there be more export bans? Like, do you think about things like, I mean, there are now with the drone industry and things like that, but is that something that should be considered?

Well, I think it's important to appreciate that in most areas, China is very advanced in manufacturing. There's only a few areas where it is not. China is a manufacturing powerhouse next level. Like, people don't... It's very impressive. Yeah, yeah. I mean, if you take, like, refining of ore, I'd say roughly China does twice as much ore refining on average as the rest of the world combined. And I think there's some areas like, say, refining gallium, which goes into solar cells.

I think they're at like 98 % of gallium refining. So China is actually very advanced in manufacturing in, I'd say, most areas.

It seems like there is discomfort with this supply chain dependence, and yet nothing's really happening on it. Supply chain dependence? Depends on, say, the gallium refining that you're saying.

Yeah, yeah. There's a...

All the rare earth stuff.

Yeah. Rare earths, which are, as you know, not rare. We actually do rare earth ore mining in the US. send the rock, put it on a train, and then put it on a boat to China that goes on another train and goes to the rare earth refiners in China who then refine it, put it into a magnet, put it into a motor self assembly, and then send it back to America. So we're really missing a lot of ore refining in America.

Isn't this worth a policy intervention?

Yes. Well, I think there are some things being done on that front. But we kind of need Optimus, frankly, to build ore refineries.

So you think the main advantage China has is the abundance of skilled labor? And that's the thing Optimus fixes? But also we need the skilled labor.

China's got like four times our population.

So there's this concern, if you think human rights are the future, that like right now, if it's the skilled laborers for manufacturing, that's determining who can build more humanoids. You know, China has more of those. It manufactures more humanoids. Therefore, it gets the OptiMai future first. Well, we'll see. It just like keeps that expansion going. It seems that you're sort of pointing out that sort of getting to a million OptiMai requires the manufacturing that the OptiMai is supposed to help us get to, right?

You can close that recursive loop pretty quickly. With a small number of Optima. Yeah. So you close the recursive loop to help the robots build the robots. And then we can try to get to tens of millions of units a year. If you start getting to hundreds of millions of units a year, I think you're going to be the most competitive country by far. We definitely can't win with just humans because China has four times our population.

And frankly, America's been running for so long that, just like a pro sports team that's been running for a very long time, tend to get complacent and entitled. That's why they stop winning because it's, you know, don't work as hard anymore. I think, frankly, just my observation is the average work ethic in China is higher than in the US. It's not just that there's four times the population, but the amount of work that people put in is higher.

You can try to rearrange the humans, but you're still one quarter of the, assuming that productivity is the same, which I think actually it might not be. I think China might have an advantage on productivity per person. We will do one quarter of the amount of things as China. We count when on the human front, and our birth rate has been low for a long time. The US birth rate has been below replacement since roughly 1971.

So we've got a lot of people retiring, or more people dying than... We're close to sort of more people domestically dying than being born. So we definitely can't win on the human front, but we might have a shot at the robot front.

Are there other things that you have wanted to manufacture in the past, but they've been too labor-intensive or too expensive that now you can come back to and say, oh, we can finally do the whatever, because we have Optimus.

Yeah, I think we'd like to do more, build more ore refineries at Tesla. So we just completed construction and have begun lithium refining it without lithium refinery in Corpus Christi, Texas. We have a nickel refinery, which is for the cathode, that's here in Austin. And these are the largest cathode refinery, largest lithium refinery, largest nickel and lithium refinery outside of China. And it's like the cathode team would say, we have the largest and the only, actually, cathode refinery in America.

Many supermanatives. Not just the largest, but it's also the only. So it's pretty big, even though it's the only one. But I mean, there are other things that you could do a lot more refineries and help America be more competitive on refining capacity. So there's basically a lot of work for the OptiMine to do that most Americans, very few Americans frankly want to do. I mean, I've actually... Is the refining work too dirty or what's the...

It's not, actually, no, we don't have toxic emissions from the refinery or anything. The chemical refinery is sort of in Travis County, like five minutes from... Why can't you do it with humans? No, you can. You run out of humans. Ah, I see. Okay, yeah. Like, no matter what you do, you have one quarter of the number of humans in America than China. So if you have them do this thing, they can't do the other thing.

So then, well, how do you build this refining capacity? Well, you could do it with the optimize. And not very many Americans are pining to do refining. I mean, how many are you running to? Very few.

Very few are pining to refine. You know, BYD is reaching Tesla production or sales in quantity. What do you think happens in global markets as Chinese production in EVs scales up?

Well, China is extremely competitive in manufacturing. So I think there's going to be a massive flood of Chinese vehicles and other basically most manufactured things. I mean, as it is, as I said, China is probably just twice as much refining as the rest of the world combined. Yeah. So if you go, you know, if you just go down to like fourth and fifth tier supply chain stuff, like at the base level, you've got energy, then you've got mining and refining.

Those foundation layers are, like I said, as a rough guess, China's doing twice as much refining as the rest of the world combined. So any given thing is going to have Chinese content because China is doing twice as much refining work as the rest of the world. And then they'll go all the way to the finished product with the cars. China is a powerhouse. I mean, I think this year China will exceed three times U .S.

electricity output. and like electricity output is a is a reasonable proxy for uh you know for the economy so like in order to run the factories and run run everything you need electricity so electricity is is a it's a good proxy for the for the real economy um and so if china is if we're trying to pass this three times the U .S. electricity output, it means that its industrial capacity, that's a rough approximation, is three times that, will be three times that in the U .S.

Reading between the lines, it sounds like what you're sort of saying is, absent some sort of humanoid recursive miracle in the next few years, on the sort of like whole manufacturing energy raw materials chain, like China will just dominate, whether it comes to like AI or manufacturing EVs or manufacturing humanoids.

In the absence of breakthrough innovations in the US, China will utterly dominate.

Interesting. Yes. Robotics being the main breakthrough innovation.

Well, if you do, like to scale AI in space, like basically you need the humanoid robots, you need real world AI, you need a million tons a year to orbit. Like let's just say, if we get the mass driver on the moon going, my favorite thing, then I think...

We'll have solved all our problems.

yeah so this is like i call that winning i call it winning time you can finally be satisfied you've

done something yes you have the master driver on the moon that's right i just want to see that thing in operation was that out of some sci-fi or where did you uh well actually the there is a

highland book the moon the moon is a harsh mistress okay yeah but that's slightly different that's a

gravity slingshot or um no they have a master i wrote okay yeah but they use that to attack So maybe it's not the greatest. Well, they just had to assert their independence for me. What are your plans for the Master of the Moon?

They asserted their independence. The Earth government disagreed, and they loved things until the Earth government agreed. That book is a hoot.

I found that book much better than his other one that everyone reads, Stranger in a Strange Land.

Yeah, Grok comes from Stranger in a Strange Land.

Yeah, yeah. But I much preferred...

The first two thirds of Stranger in a Strange Land are good, and then it gets very weird in that portion. Yeah. Yeah. But there's still some good concepts in there.

Yeah. One thing we were discussing a lot is kind of your system for managing people. Like, you interviewed the first few thousand of SpaceX employees and lots of other companies. What is this? It obviously doesn't scale. Well, yes. But what doesn't scale? Me. Sure, sure. I know that. But like, what are you looking for? I mean, literally, there's not enough hours in a day. It's impossible. But what are you looking for that someone else who's good at interviewing and hiring people?

What's the je ne sais quoi?

Well, at this point, I think I've got, I might have more training data on evaluating technical talent, especially, but talent of all kinds, I suppose, but technical talent, especially, given that I've done so many technical interviews and then seen the results, technical interviews, seen the results. So my training set is enormous and has a very wide range. Generally, the thing I ask for are bullet points for evidence of exceptional ability. So it's like, these things can be like pretty off the wall.

It doesn't need to be in the domain, the specific domain, but evidence of exceptional equality. So if somebody can cite even one thing, but let's say three things where you go, wow, wow, wow, then that's a good sign.

But why do you have to be the one to determine that? No, I don't.

I can't be. It's impossible. I mean, headcount across all companies, 200 ,000 people.

Right. But in the early days, what was it that you were looking for that couldn't be delegated in those interviews?

Well, I guess I need to build my training set. It's not like I would bat 1 ,000 here. I would make mistakes. But then I would be able to see where I thought somebody would work out well, but they didn't. And then why did they not work out well? And what can I do to, I guess, RL myself to, in the future, have a better batting average when interviewing people? My batting average is still not perfect, but it's very high.

What are some surprising reasons people don't work out? Surprising reasons? Like, they don't understand technical domain, etc., etc. But, like, you've got, like, the long tail now of, like, I was really excited about this person. It didn't work out. Curious why that happens.

Yeah, so the... I mean, generally what I tell people, or tell myself, I guess, aspirationally, is don't look at the resume. Just believe your interaction. so if the resume may seem very impressive and it's like wow you know resume looks good but if the if the conversation uh after 20 minutes is is that conversation is not well um you should believe the conversation not the not the not the paper i feel like

part of your method is that you know there was this meme in the media a few years back about tesla being a revolving door of uh executive talent whereas actually i think when you look at it, Tesla's had a very consistent and internally promoted executive bench over the past few years. And then at SpaceX, you have all these folks like Mark Jankosa and Steve Davis and - Steve Davis runs a sporting company. No, yeah, yeah. But Bill Reilly and folks like that.

And it feels like part of has worked well is having very capable technical deputies. What do all of those people have in common?

Well, so the, I mean, the Tesla sort of senior team, at this point, it's probably got average tenure of 10 or 12 years. It's quite long. Yeah, quite a long tenure. Yeah. So, but there were times when Tesla went through extremely rapid, an extremely rapid growth phase. And so it was somewhat, things were just somewhat sped up. And when a company, as you know, a company goes through different orders of magnitude of size, people who could help manage, say, a 50-person company versus a 500-person company versus a 5 ,000-person company versus a 50 ,000-person company.

Yeah, you agree with people.

Yeah, it's just not the same team. It's not always the same team. So if a company is growing very rapidly, the rate at which executive positions will change will also be proportionate to the rapidity of the growth, generally. Then Tesla had a further challenge where when Tesla had very successful periods, we would be relentlessly recruited from, like relentlessly. like when Apple had their electric car program they were carpet bombing Tesla with recruiting calls it was engineers just unplugged their phones like it's just

I'm trying to get worked on here

yeah if I get one more call from an Apple recruiter but they were opening offer without any interview would be like double the compensation at Tesla so So we had a bit of the Tesla pixie dust thing where it's like, oh, if you hire a Tesla executive, suddenly everything's going to be successful. And I fall and pray to the pixie dust thing as well, where it's like, oh, we'll hire someone from Google or Apple and they'll be immediately successful.

But that's not how it works. People are people. There's not like magical pixie dust. Yes. So when we had the pixie dust problem, we would get relentlessly recruited. And then also Tesla being, engineering especially being primarily in Silicon Valley, it's easier for people to just, like they don't have to change their life very much. They can just, you know, their commute is going to be the same.

So how do you prevent that? How do you prevent the pixie dust effect where everyone's trying to poach other people?

I don't think there's much we can do to stop it. But that's one of the reasons why Tesla... Really, being in Silicon Valley and having the pixie dust thing at the same time meant that there was just a very, very aggressive recruitment.

Maybe being in Austin helps, then.

Austin, yeah, it still helps. I mean, Tesla still has a majority of its engineering in California. So the, you know, for getting engineers to move, I call it the significant other problem. Yes.

So when others have jobs, yeah?

Yeah, yeah, exactly. So for Starbase, that was particularly difficult. Yes. Since the odds of, you know, finding a non-SpaceX job -

In Gransdale, Texas.

Pretty low, yeah. Yeah. Yeah, it's quite difficult. I mean, it's like a technology monastery, sort of thing. You know, remote and mostly dudes.

It's not much of an improvement over SF. Yeah.

But if you go back to these people who've really been very effective in a technical capacity at Tesla, at SpaceX, and those sorts of places, what do you think they have in common other than, like, is it just that they're very sharp on the rocketry or the technical foundations? Or do you think it's something organizational? It's something about their ability to work with you? Is this their ability to be flexible but not too flexible? What makes a good sparring partner for you?

I don't think of a sparring partner. If somebody gets things done, I love them. And if they don't, it's pretty straightforward. It's not like some idiosyncratic kind of thing. If somebody executes well, I'm a huge fan. And if they don't, I'm not. But it's not about mapping to my idiosyncratic preferences. I'll certainly try not to have it be mapping to my idiosyncratic preferences. So yeah. Yeah. But generally, I think it's a good idea to hire for talent and drive and trustworthiness.

I think goodness of heart is important. I'd awaited that at one point. So, like, are they a good person, trustworthy, sort of smart and talented and hardworking? If so, you can add domain knowledge. But those fundamental traits, those fundamental properties you cannot change. So most of the people who are at Tesla and SpaceX did not come from the aerospace industry or the order industry.

What is most set to change about your management style as your companies have scaled from 100 to 1 ,000 to 10 ,000 people? You're known for this very micromanagement, just getting into the details of things. Nano management, please. Pico management.

Femto management.

So you're saying...

We're going to go all the way down to Flanks Boston. All the way down to Heisenberg's in Sydney, Bristol.

Yeah, well, how do you, I mean, are you still able to get into details as much as you want? Would your companies be more successful if they were smaller? How do you think about that?

Well, because I have a fixed amount of time in the day, my time is necessarily diluted as things grow and as the span of activity increases. So, you know, it's impossible for me to actually be a micromanager because that would imply I have some like thousands of hours per day. It is a logical impossibility for me to micromanage things. So now there are times when I will drill down into a specific issue because that specific specific issue is the limiting factor on the progress of the company.

But the reason for drilling into some very detailed item is because it is the limiting factor. It's not arbitrarily drilling into tiny things. And like I said, obviously, from a time standpoint, it is physically impossible for you to arbitrarily going to tiny things that don't matter. And that would result in failure. But sometimes the tiny things are decisive in victory.

Famously, you switched the starship design from composites to steel. Yes. And you made that decision. Like that wasn't a, you know, people were going around there like, oh, we found something better, boss. Like that was you encouraging people against some resistance. Can you tell us how you came to that whole composite steel switch?

Yeah, so desperation, I'd say. Originally, yeah, we were going to make Starship out of carbon fiber. And carbon fiber is pretty expensive. Like the you know, you can generally when you do volume production you can get any given thing to be to start to approach its material cost. The problem with carbon fibers is that material cost is still very high. So it's about 50 times, particularly if you go for a high-strength specialized carbon fiber that can handle cryogenic oxygen, it's like roughly 50 times the cost of steel.

And at least in theory, it would be lighter. People generally think of steel as being heavy and carbon fiber as being light. And for room temperature applications, you know, like say, more or less room temperature applications like a Formula One car, static aerostructure, or any kind of aerostructure really, you're going to probably be better off with carbon fiber. Now the problem is that we were trying to make this enormous rocket out of carbon fiber, and our progress was extremely slow.

And it's been picked in the first place just because it's light? Yes. Like at first glance, like most people would think that the choice for making something light would be carbon fiber. Now the thing is that when you make something very enormous out of carbon fiber and then you try to have the carbon fiber be efficiently cured, meaning not room temperature cured because sometimes you've got 50 plies of carbon fiber. And carbon fiber is really carbon string and glue and in order to have high strength, you need an autoclave.

So something that can, that's essentially a high pressure oven. And if you have something that's a gigantic, the oven's got to be bigger than the rock one. So we're trying to make the autoclave that's bigger than any autoclave that's ever existed. Or do room temperature cure, which takes a long time and has issues. But the fundamental issue is that we're just making very slow progress with carbon fiber.

I think the meta question is why it had to be you who made that decision. There's many engineers on your team. Yeah, how did the team not arrive at steel? Yeah, exactly. This is part of a broader question of understanding your comparative advantage at your companies.

So, because we were making very slow progress with carbon fiber, I was like, okay, we've got to try something else. Now, for the Falcon 9, the primary airframe is made of aluminum lithium, which is a very very good strength to weight. And actually, it has about the same, maybe better strength to weight for its application than carbon fiber. But aluminum lithium is very difficult to work with. In order to weld it, you have to do something called friction steel welding, where you join the metal without it entering the liquid base.

So it's kind of wild that you could do that. But with this particular type of welding, you can do that. But it's very difficult to, like, say, let's say you want to make a modification or attach something to aluminum lithium. You now have to use mechanical attachment with seals. You can't weld it on. So I wanted to avoid using aluminum lithium for the primary structure for Starship. And there was this very special grade of carbon fiber that had very good mass properties.

So with rockets, you're really trying to maximize the percentage of the rocket that is propellant, minimize the mass, obviously. and the but like say we were making very slow progress and and and as at this rate we're never gonna get to Mars so we better think of something else I don't want to use aluminum lithium because of the difficulty of friction still welding especially doing that at scale was hard enough at 3 .6 meters in diameter, let alone at 9 meters or above.

Then I said, well, what about steel? And so, now, I had a clue here because some of the early U .S. rockets had used very thin steel. The Atlas rockets had used a steel balloon tank. So it's not like steel had never been used before. It actually had been used. And when you look at the material properties of stainless steel, especially if it's been full-hardened stainless steel at cryogenic temperature, the strength weight is actually similar to carbon fiber.

So if you look at the material properties at room temperature, it looks like the steel is going to be twice as heavy. But if you look at the material properties at cryogenic temperature of full hot steel, stainless, of particular grades, then you actually get to a similar strength weight as carbon fiber. And in the case of Starship, both the fuel and the oxidizer are cryogenic. So for Falcon 9, the fuel is rocket-propelled grade kerosene, basically like a very pure form of jet fuel.

But that is roughly room temperature, although we do actually chill it slightly below. We chill it like a beer. Delicious. We do chill it, but it's not cryogenic. In fact, if we made it cryogenic, it would just turn to wax. So, but for Sarship, it's liquid methane and liquid oxygen. They are liquid at similar temperatures. So, basically, almost the entire primary structure is at cryogenic temperature. So then you've got a 300 series stainless that's strain hardened.

Because it's at almost all things at cryogenic temperature, actually has a similar strength of weight as carbon fiber, but costs 50 times less in raw material and is very easy to work with. You can weld stainless steel outdoors. You could smoke a cigar while welding stainless steel. It's very resilient. You can modify it easily. If you want to attach something, you just weld it right on. So, very easy to work with, very low cost. And like I said, at cryogenic temperature, similar strength weight to carbon fiber.

Then when you factor in that, we have a much reduced heat shield mass because the melting point of steel is much greater than the melting point of aluminum. It's about twice the melting point of aluminum. So you can just run the rocket much hotter? Yes. So especially for the ship, which is coming in like a blazing meteor, you can greatly reduce the mass of the heat shield. So you can cut the mass of the windward part of the heat shield maybe in half.

and you don't need any heat shielding on the leeward side. So the net result is actually the steel rocket weighs less than the carbon fiber rocket because the resin in the carbon fiber rocket starts to melt. So basically, carbon fiber and aluminum have about the same operating temperature capabilities. and whereas steel can operate at twice temperature. I mean, these are very rough approximations. People will... I won't build a rocket base. What I mean is like people will say, oh, he said it's twice.

It's actually 0 .8. Shut up, assholes. That's what the main comment's going to be about. God damn it. Okay, so the point is that actually in retrospect, we should have started with done steel in the beginning. It was dumb not to do steel.

Okay, but to play this back to you, what I'm hearing is that steel was a riskier, less proven path other than the early US rockets versus carbon fiber was like a worse but more proven out path. And so you need to be the one to push for, hey, we're going to do this riskier path and just figure it out. And so you're fighting like a sort of conservatism in a sense.

That's why I initially said like the issue is that we weren't making fast enough progress. We were having trouble making even a small barrel section of the carbon fiber that didn't have wrinkles in it. Because at that large scale, you have to have many plies, many sort of layers of the carbon fiber. You've got to cure it, and you've got to cure it in such a way that it doesn't have any wrinkles or defects. The carbon fiber is much less resilient than steel.

It has much less toughness. like stainless steel will stretch and bend the column fiber will tend to shatter so so toughness being the area under the stress strain curve so that you're generally going to have to do better with steel stainless steel to be precise

one other Starship question so I visited Starbase I think it was two years ago I went with Sam Teller and that was awesome it was very cool to see in a whole bunch of ways. One thing I noticed was that people really took pride in the simplicity of things where, you know, everyone wants to tell you how Starship is just a big soda can and, you know, we're hiring welders and, you know, if you can weld in any industrial project, you can weld here.

But there's a lot of pride in the simplicity. And... Well, frankly, Starship is a very complicated rocket. So that's what I'm getting at. Are things simpler or are they complex?

I think maybe just what they're trying to say is that you don't have to have prior experience in the rocket industry to work on a Starship. Somebody just needs to be smart and work hard and be trustworthy and they can work on a rocket. They don't need prior rocket experience. Starship is the most complicated machine ever made by humans, by a long show.

In what regards?

Anything really. There isn't a more complex machine. I'd say that there's pretty much any project I can think of would be easier than this. And that's why nobody has ever made a fully reusable open rocket. It's a very hard problem. Many smart people have tried before, very smart people, with immense resources and they fail. and we haven't succeeded yet. Falcon is partially reusable, but the upper stages are. Starship version 3, I think this design, that it can be fully reusable and that full reusability is what will enable us to become a multi-planet civilization.

Can you say about the scenarios?

I don't, like I said, So any technical problem, even like a hydronic ladder or something like that, is an easier

problem than this. We spend a lot of time on bottlenecks. Can you say what the current Starship bottlenecks are, even at a high level?

I mean, trying to make it not explode, generally. That old chestnut. Really wants to explode. We've had two boosters explode on the test end. One obliterated the entire test facility. So at least takes like one mistake. And I mean, the amount of energy contained in Starship is insane. So is that why it's harder than Falcon? It's because it's just more energy? It's a lot of new technology. It's pushing the performance envelope. The Raptor 3 engine is a very, very advanced engine, by far the best recognition ever made.

but it desperately wants to blow up I mean, just to put things in perspective here on Liftoff the rocket is generating over 100 gigawatts of power it's 20 % of US electricity inside

it's a great comparison while not exploding sometimes sometimes, but sometimes

how does it not explode there's thousands of ways that it could explode and only one way that it doesn't. So we wanted to not really not explore, but fly reliably on a daily basis, like once per hour. And obviously, you know, blows up a lot. It's very difficult to maintain that launch cadence. Yes. And then I'm going to say, like, what's the what's the single biggest remaining problem for Starship? It's having the heat shield be reusable such that no one has ever made a reusable orbital heat shield.

So the heat shield's got to make it through the ascent phase without shucking a bunch of tiles. And then it's going to come back in and also not lose a bunch of tiles or overheat the main airframe. Isn't that hard because it's kind of fundamentally a consumable? uh well yes but your brake pads in your car are also consumable but they last a very long time so it just needs to last a very long time um but that's it just yeah i mean we have brought the ship back and had it do a soft landing in the ocean we've done that a few times but but it lost a lot of tiles you know you know it was not reusable

without a lot of work. So even though it did land, it did come to soft landing, it would not have been reusable without a lot of work. So it's not really reusable in that sense. That's the biggest problem that remains is fully reusable heat shield. So if you want to be able to land it, refill propellant and fly again. You can't do this laborious inspection of there are 40 ,000 tiles type of thing.

I'm curious how you drive, like when I read biographies of yours, it just, it seems like you're just able to drive the sense of like urgency and drive the sense of like, this is the thing that can scale. And I'm curious why you think other organizations of your, like SpaceX and Tesla are really big companies now and you're still able to keep that culture. What goes wrong with other companies such that they're not able to do that?

I don't know but like today you said you had like a bunch of SpaceX meetings like what is it that you're doing there that's like keeping that that's adding urgency yeah yeah yeah

well I don't know I guess the urgency is going to come from where I was leading the company so my sense of urgency I have like maniacal sense of urgency so that maniacal sense of urgency projects through the rest of the company

is it because of consequences they're like if you know Elon's had a crazy deadline, but if I don't get it, I know what happens to me. Is it just you're able to identify bottlenecks and get rid of them so people can move fast? How do you think about why your companies are able to move fast?

Yeah, I'm constantly addressing the limiting factor. so I mean on the deadlines front I mean I generally actually try to aim for a deadline that I at least think is at the 50th percentile so it's not like an impossible deadline but it's the most aggressive deadline I can think of that could be achieved with 50 % probability which means that it will be late half the time um and um but whatever like there is like a law of gases expansion that applies to schedules like whatever given whatever schedule you like if you said we're going to do this something in like five years which to me is like infinity time um it will expand to fully available schedule and it'll

take five years um you know like there's like this there's a physical limit it like that like physics will limit how fast you can do certain things like so like scaling up manufacturing there's like there's a rate at which you can move the atoms um and scale manufacturing that's why you can't like instantly make you know a million of something millions a year or something uh you've got you've got to design manufacturing line you can bring it up you've got to ride the s curve of production um so yeah i mean i guess like Like, what can I say that's actually helpful to people?

I think generally a maniacal sense of urgency is a very big deal. So, and you want to have an aggressive schedule, and you want to figure out what the limiting factor is at any point in time and help the team address that limiting factor.

Can you maybe talk about the, so Starlink was slowly in the works for many years.

Yeah, we talked about it all the way in the beginning of the company.

Yeah. And so then there was a team you had built in Redmond. And then at one point you decided this team is just not cutting us. But again, how did you, like, it went for a few years slowly. And so why did this, why didn't you act earlier? And why did you act when you did? Like why was that the right moment at which to act?

I mean, I have these very detailed engineering reviews weekly. That's maybe a very unusual level of granularity. I don't know anyone who runs a company, or at least a manufacturing company, that goes with the level of detail that I go into. So it's not as though, like I have a pretty good understanding of what's actually going on because we go through things in detail. And I'm a big believer in skip level meetings where the individuals, instead of having the person that reports to me say things, it's everyone that reports to them says something in the technical review.

And there can't be advanced preparation. So otherwise, you're going to get glazed, as I say these days.

Yeah, exactly. Very Gen Z of you.

Very Gen Z.

How do you prevent advanced administration? You just call them randomly?

No, just go around the room. Everyone provides an update. So, I mean, it's a lot of information to keep in your head Because you've got them, say if you have meetings weekly or twice weekly, you've got a snapshot of what that person said. And you can then plot the progress points. You can sort of mentally plot the points on the curve and say, are we converging to a solution or not? or are we you know I'll take drastic action only when I conclude that success is not in the set of possible outcomes so when I say okay when I finally reach the conclusion that okay unless drastic action is done we have no chance of success then I must take

drastic action so that's I came to that conclusion in 2018 into a crash caption and fix the problem.

How many, you know, you've got many, many companies, and in each of them, it sounds like you do this kind of deep engineering understanding of what the relevant bottlenecks are, so you can do these reviews with people. Yeah. You've been able to scale it up to five, six, seven companies. Within one of these companies, you have many different mini companies within them. What determines the maximum here? Could you have like 80 companies? 80? No. But you have so many already.

That's already remarkable.

Why this current number?

I know, so... We can barely keep one company together. It depends on the situation. So I actually don't have regular meetings with a foreign company. So the foreign company is sort of cruising along. Basically, if something is working well and making good progress, then there's no point in me spending time on it. So I actually allocate time according to where the limiting factor or the problem, where are things problematic? Or where are we pushing against, like what is holding us back?

I focus at risk of saying the words too many times, the limiting factor. so basically if something's going really well they don't see much of me but if something's going badly they'll see a lot of me or not even badly it's like it's a limiting factor it's not exactly going badly but it's the thing that we need to make go faster

and so when something's a limiting factor at SpaceX or Tesla are you like talking weekly daily with the engineers that's working on it? How does that actually work?

Most things that are limiting factor are weekly and some things are twice weekly. So the AI5 chip review is twice weekly. And so it's every Tuesday and Saturdays is the chip review.

Is it open-ended in how long it goes?

Technically, yes, but usually it's like two or three hours. sometimes less it depends on how much information you've got to go through

I'm just trying to tease out the differences here because the outcomes seem quite different and so I think it's interesting to note what inputs are different and it feels like the corporate world one like you were saying just the CEO doing engineering reviews does not always happen despite the fact that that is what the company is doing but then time is often pretty finely sliced into half-hour meetings or even 15-minute meetings. And it seems like you hold more open-ended, we're talking about it until we figure it out type meetings.

Yeah.

Yeah, sometimes. But most of them seem to more or less stay on time. So, I mean, today's Starship engineering interview went a bit longer because there are more topics to discuss. Trying to figure out how to scale to a million plus tons per year is quite challenging.

Can I ask a question? You said about Optimus and AI that they're going to result in double digit growth rates within a matter of years. Oh, like the economy? Yeah. Yes.

I think that's right.

What was the point of the doge cuts if the economy is going to grow so much?

Well, I think like waste and fraud are not good things to have, you know. I was actually pretty worried about, I guess, I mean, I think in the absence of AI and robotics, we're actually totally screwed. Because the national debt is piling up like crazy. um now our interest payments the interest payments to national debt exceed the military budget which is $1 1 trillion so over $1 1 trillion just the interest payments um you know that was like i was like okay pretty concerned about that maybe if i spend some time we can slow down the bankruptcy of the united states um and give us enough time for the ai and robots to you know help solve the national debt

or not help solve it's the only thing that could solve the national debt. Like we are 1000 % going to go bankrupt as a country and fail as a country without AI and robots. Nothing else will solve the national debt. And so we'd like to, well, we just need, we need enough time to build the AI and robots to not go bankrupt before then. I guess the thing I'm curious about is when

When Doge starts, you have this enormous ability to enact reform. Not that enormous. Sure, sure. But totally by your point that it's important that AI and robotics drive product improvements, drive GDP growth. But why not just directly go after the things you were pointing out? You know, like tariffs on certain components or whether it's like permitting. I'm like the president.

and very hard to cut things that are obvious waste and fraud, like ridiculous waste and fraud. What I discovered that is it's extremely difficult even to cut very obvious waste and fraud from the government because the government has to operate on who's complaining. like if you cut off payments to fraudsters, they immediately come up with the most sympathetic sounding reasons to continue the payment. They don't say, please keep the fraud going. They say, you know, they're like, you're killing baby pandas.

And we're like, meanwhile, there's no baby pandas are dying. They're just making it up. The fraudsters are capable of coming up with extremely compelling sort of heart-wrenching stories that are false, but nonetheless sound uh, sympathetic and that, that's what happened. Um, and, uh, so it's like, perhaps I should have known better. Um, and, uh, but I thought, wait, let's take a, let's, let's, let's try to cut some amount of waste and pour from the government.

Maybe there shouldn't be, you know, 20 million people, uh, are marked as alive in social security who are definitely dead. and over the age of 115. The oldest American is 114. So it's safe to say if somebody is 115 and marked as alive in the social security database, there's either a typo. Somebody should call them and say, we seem to have your birthday wrong or we need to mark you as dead. One of the two things.

Very intimidating call to get. Well, it seems like a reasonable thing. And if, like, say their birthday is in the future, and they have a small business administration loan, and their birthday is 2165, we either, again, have a typo or we have fraud. So we say we appear to have gotten the century of your birth incorrect. Or a great plot for a movie. Yes. When I'm in my ludicrous fraud, this is what I'm in my ludicrous fraud.

Were those people getting payments? Some were getting payments from Social Security. But the main fraud vector was to mark somebody as alive in Social Security and then use every other government payment system to basically do fraud. Because what those other government payment systems do, they will simply do an are you alive check to the Social Security database. It's a bank shot.

What would you estimate as the total amount of fraud from this mechanism?

My guess is, and by the way, the Government Accountability Office has done these estimates before. I'm not the only one who's coming out of this. In fact, I think the GAO did analysis, a rough estimate of fraud during the Biden administration and calculated at roughly half $1 1 trillion. So don't take my word for it. Take a report issued during the Biden administration. How about that? From this social security mechanism? It's one of many. It's important to appreciate that the government is very ineffective at stopping fraud.

Because it's not like it was a company, stopping fraud, you've got a motivation because it's affecting the earnings of your company. But the government, they just print more money. So it's not like you need caring and competence. And these are in short supply at the federal level. Yeah, I'm sorry. I mean, when you go to the DMV, do you think, wow, this is a bastion of competence? Well, now imagine it's worse than the DMV because it's the DMV that can print money.

So was it not possible? At least the state level DMVs need to, the states more or less need to stay within their budget and go bankrupt. But the federal government just prints for money.

Well, is it not possible to cut that? If there's actually half 1 trillion of fraud, why was it not possible to cut all that?

Because when essentially, we did, we actually, no, you really have to stand back and recalibrate your expectations for competence. Because you're operating in a world where you've got to sort of make ends meet, like you've got to pay your bills, you've got to... Buy the microphones. Yeah, yeah, exactly. So it's not like there's a giant, largely uncaring monster bureaucracy, and a bunch of necromancy computers that are just sending payments. One of the things that the Doge team did, and it sounds so simple, that probably will save, let's say, $100 billion, maybe $200 billion a year, is simply requiring that payments from the main treasury computer, which is called PEMs, like Payment Accounts Master or something like that, there's 5 trillion

payments here requiring that any payment that goes out have a payment appropriation code make it mandatory, not optional and that you have anything at all in the comment field because you have to recalibrate how dumb things are payments were being sent out with no appropriation code not checking back to any congressional appropriation and no explanation And this is why the Department of War, formerly the Department of Defense, cannot pass an audit because the information is literally not there.

Recalibrate your expectations.

I want to better understand this half a trillion number because there was an IG report in 2024. How? You must like, why is it so low? Maybe, but we found that like over seven years, the social security fraud they estimated was like 70 billions over seven years, so like 10 billion a year. So I'd be curious to see what like the other 490 billion is.

Federal government expenditures are $7 .5 1 trillion a year. How competent do you think government is? The discretionary spending there is like 15%. Yeah, but it doesn't matter. Most of the forward is non-discretionary. It's basically a fordulent Medicare, Medicaid, Social Security, disability. there's a zillion government payments. Yeah. And a bunch of these payments are, in fact, they're block transfers to the states. So the federal government doesn't even have the information in a lot of cases to even know if there's fraud.

Let's consider, let's like reductio ad absurdum. The government is perfect and has no fraud. What is your probability estimate of that?

I mean, zero.

Okay. Okay. So then would you say that fraud and waste, that the government is 90 %? That also would be quite generous. But if it's only 90%, that means that there's $750 billion a year of waste and fraud. And it's not 90%. It's not 90 % effective.

This seems like a strange rate of first principles, the amount of fraud in the government. Just like how much do you think there is? And then, anyways, we don't know how to do it live, But I'd be curious to see that.

You know a lot about fraud at Stripe. People are constantly trying to do fraud.

Yeah, but as you say, it's like a little bit of a, we've really ground it down, but it's a little bit of a different problem space because you're dealing with a much more heterogeneous set of fraud vectors here than we're.

Yeah, but I mean, at Stripe, you have high confidence and you try hard. You have high confidence and high caring. But still, fraud is non-zero. Now imagine it's at a much bigger scale, there's much less competence and much less caring. You know, back in PayPal back in the day, we were trying to manage fraud down to about 1 % of the payment volume. And that was very difficult, took a tremendous amount of competence in caring to get fraud merely to 1%.

Now imagine that you're in an organization where there's much less caring and much less competence. It's going to be much more than 1%.

How do you feel now looking back on politics and doing stuff there, where it feels like, looking from the outside in, two things have been quite impactful. One, the America PAC, and two, the acquisition of Twitter at the time. But also it seems like there was a bunch of heartache. and so what's your grading of the whole experience?

Well, I think those things need to be done to maximize the probability that the future is good. Politics generally is very tribal, and it's very tribal. People lose their objectivity usually with politics. They generally have trouble seeing the good on the other side or the bad on their own side. That's generally how it goes. That, I guess, was one of the things that surprised me the most, is you often simply cannot reason with people. If they're in one tribe or the other, they simply believe that everything their tribe does is good and anything the other political tribe does is bad.

And persuading them otherwise is almost impossible. Um, so anyway, but, um, I think, I think overall those actions, um, acquiring Twitter, getting Trump elected, even though it makes a lot of people angry. Um, I think those, I think those actions are good for, we're good for civilization.

Um, yeah. Well, how does it feed into the future you're excited about?

Well, America needs to be strong enough to last long enough to extend life to other planets and to get AI and robotics to the point where we can ensure that the future is good. On the other hand, if we were to descend into, say, communism or some situation where the state was extremely oppressive, that would mean that we might not be able to become multi-planetary. The state might stamp out our progress in AI and robotics.

How do you feel about Optimus, Grok, etc. are going to be leveraged by, and not just any revenue-maximizing company's products will be leveraged by the government over time. How does this concern manifest in what private companies should be willing to give governments? What kinds of guardrails should AI models be made to do whatever the government that has contracted them out to do, ask them to do, should Grok get to say, actually, even the military wants to do X, no, Grok will not do that?

I think probably the biggest danger of AI, or maybe the biggest danger of AI and robotics going wrong is government. Interesting. You know, I mean, the way to think, like, people who are opposed to corporations or or worried about corporations, should really worry the most about government. Because government is just a corporation in the limit. It's a government... It is... Government is just the biggest corporation with a monopoly on violence. So I always find it like a strange dichotomy where people would think corporations are bad but the government is good when the government is simply the biggest and worst corporation.

But people have that dichotomy. They somehow think at the same time that government can be good, but corporations bad. And this is not true. Corporations have better morality than the government. So I actually think that is the thing to be worried about. It's like if the government could potentially use AI and robotics to suppress the population. Like that is a serious concern.

As a guy building AI and robotics, how do you prevent that?

Well, I think if you have a limited government, if you limit the powers of government, which is really what the US Constitution is intended to do, is to limit the powers of government, then you're probably going to have a better outcome than if you have more government. But robotics will be available to all governments, right? Not about all governments. It's difficult to predict the, like I said, what's the end point or what is many years in the future, but it's difficult to predict the path along that way.

like if civilization progresses AI will vastly exceed the sum of all human intelligence and there will be far more robots than humans along the way what happens it's very difficult to predict

I mean it seems like one thing you could do is just say you are not allowed to whatever government decks you're not allowed to use Optimus to do XYZ just write out like a policy I mean I think you treated recently that Grok should have a moral constitution. And one of those things could be that we limit what governments are allowed to do with this advanced technology.

I mean, yeah, we can do what is... I mean, technically, I mean, if the politicians pass a law and they can enforce that law, then it's hard to not do that law. The best thing we can have is limited government where you have the appropriate cost checks between the executive, judicial, and legislative branches.

I guess the reason I'm curious about it is this, at some point it seems like the limits will come from you, right? Like you've got the Optimus, you've got the Space GPUs, you've got the... You think I'll be the boss of the government. Or you will get the... I mean, already it's the case with SpaceX that for things that are crucial to the, like the government really cares about getting certain satellites up in space, whatever, like it needs SpaceX.

It is a necessary contractor. And you are in the process of building more and more of the technological components of the future that will have an analogous role in different industries. And you could have this ability to like set some policy that is suppressing classical liberalism in any way. My companies will not help in any way with that, or some policy like that.

I will do my best to ensure that anything that's within my control maximizes the good outcome for humanity. I think anything else would be short-sighted, because obviously I'm part of humanity. So I like humans.

Pro-human, pro-human. You've mentioned that Dojo 3 will be used for space-based compute. You really read what I say. I don't know if you know Twitter, but I know you a lot. You have a lot of followers. Dead giveaway.

How did you just show my secrets? I post them.

How do you design a ship for space? What changes?

Well, I guess you want to design it to be more radiation tolerant and run at a higher temperature. So roughly if you increase the operating temperature by 20th set in degrees Kelvin, you can cut your radiator mass in half. So running at a higher temperature is helpful in space. I mean, there's various things you can do for shielding the memory. But neural nets are going to be very resilient to bit flips. So most of what happens for radiation is random bit flips.

But if you've got a multi-trolling parameter model and you get a few bit flips, it doesn't matter. it's much like curiosity programs are going to be much more sensitive to bit flips than some giant parameter file so i just designed to run hot and i think you pretty much do it the same way that you do things on earth apart from make it run

hotter i mean the solar array is most of the weight on the satellite is there a way to make the GPU is even more power dense than what NVIDIA and TPUs and et cetera are planning on doing that would be especially privileged in the space-based world?

Well, I mean, the basic math is if you can do about a kilowatt per reticle, then you'd need 100 million full radical chips to do 100 gigawatts. So depending what your yield assumptions are, that tells you how many chips you need to make. But if you're going to have 100 gigawatts of power, You need, you know, 100 million chips running that are running at kilowatt sustained output per reticle.

Basic math. 100 million chips depends on, yeah, if you look at the die size of something like black wall GPUs or something and how many you can get out of a wafer, you can get like on the order of dozens or less per wafer. So basically, this is a world where if we're putting that out every single year, you're producing millions of wafers a month. That's the plan with TeraFab? Millions of wafers a month of advanced process notes?

Yeah, it could be some number north of a million, I think. You've got to do the memory too.

Yeah. You're going to make a memory fab?

I think that TeraFab's got to do memory. It's got to do logic memory and packaging.

I'm very curious how somebody gets started. this is like the most complicated thing man has ever made. And obviously, like, if anybody's up to the task, you're up to the task. Like, what do you, so you realize this is a bottleneck, and you go to your engineers and like, what is the next, like, what do you tell them to do? I want a million wafers a month in 2030. What is the next, like, what do you, That's right.

Do you like call ASML? Like, what is the next step? That's what I want.

What is the next step? That's so much to ask.

Well, we make a little fab and see what happens, make our mistakes at a small scale, and then make a big one. Is a little fab done? No, it's a little done. We're not going to keep that cat in the bag. That cat's going to come out of the bag. It'll be like drones hovering over the bloody thing. You'll be able to see its construction progress on X in real time. I don't know. We could just flounder in failure.

to be clear, success is not guaranteed. But since we want to try to make something like 100 million, we want 100 gigawatts of power and 100 chips that can take 100 gigawatts. Right. So call it by 2030. so then it will take as many chips as our suppliers will give us I've actually said this to TSMC and Samsung and Micro and it's like please build more fabs faster and we will guarantee you to buy the output of those fabs so they're already moving as fast as they can it's not like to be clear it's not like us you know it's not like uh either it's it's not like it's us plus them you know there's a narrative

that the people doing ai want a very large number of you know chips as quickly as possible and then many of the input suppliers the fabs but also you know the turbine manufacturers are not ramping up production very quickly no yeah the explanation you hear is that they're dispositionally conservative you know they're taiwanese or german as the you know story may be and they just like don't believe they say like is that really the explanation or is there something

else well i mean it's reasonable like if somebody's been in say the computer memory business for uh 30 or 40 years and they've seen cycles they've seen like boom and bust like 10 times yeah you So that's a lot of layers of scar tissue. So it's like during the boom times, it looks like everything is going to be great forever. And then the crash happens, and then they're desperately trying to avoid bankruptcy. And then there's another boom and another crash.

Are there other ideas you think others should go pursue that you're not for whatever reasons right now?

I mean, there are a few companies that are pursuing new ways of doing jobs. but they're just not scaling fast.

I don't even mean with an AI, I mean just generally.

I'd say like people should do the thing that where they find that they're highly motivated to do that thing as opposed to, you know, something of some idea that I suggest. But they should do the thing that they find personally interesting and motivating to do. But going back to the limiting factor, I use that phrase about a hundred times. The current limiting factor that I see in the timeframe, in the sort of 20, 29, 20, like In the three to four year time frame, it's chips.

In the one year time frame, it's energy, power production, electricity. It's not clear to me that there's enough usable electricity to turn on all the AI chips that are being made. Towards the end of this year, I think people are going to have real trouble turning on. chip output will exceed the ability to turn chips on.

What's your plan to deal with that world?

Well, we're trying to accelerate electricity production. I guess that's maybe one of the reasons that XAI will be maybe the leader, hopefully the leader, is that we'll be able to turn on more chips than other people can turn on faster. Because we're good at hardware. and generally the innovations from the corporations that call themselves labs, the ideas tend to flow. It's rare to see that there's more than about a six-month difference between the ideas travel back and forth with the people.

So I think you sort of hit the hardware wall and um and then whatever whichever company can scale hardware the fastest will be the leader and so i think xci will be able to scale hardware the fastest and therefore most likely will be the

leader you you jokes or you know um we're self-conscious about uh you know using the uh the limiting factor phrase again but i actually think there's something deep here and if you look at a lot of things we've touched on over the course of it maybe kind of a good note to end on like if you think of a senescent lower agency company it would have some bottleneck and not really be doing anything about it um you know mark and recent had the line of most people are willing to endure any amount of chronic pain to avoid acute pain and it feels like a lot of the cases we're talking about are just leaning into the acute pain whatever

it is it's like okay we We got to figure out how to work with steel, or we got to figure out how to run the chips in space, or we'll take some near-term acute pain to actually solve the bottleneck. And so that's kind of a unifying thing.

I have a high-pain threshold that's helpful. Solve the bottlenecks. Yes. One thing I can say is, I think the future's going to be very interesting. And as I said, the dog was up, I was literally at Dallas, I think it was on the ground for like three hours or something. It's better to be, it's better to err on the side of optimism and be wrong than err on the side of pessimism and be for quality of life.

So, you know, your happiness will be, you'll be happier if you are on the side of optimism rather than erring on the side of pessimism. And so I recommend erring on the side of optimism. Nice to do that. Cool.

Yolan, thanks for doing this. Thank you. All right, thanks, guys. All right. Oh, great stamina. Hopefully this encounters the pain and the pain tolerance.
