In brief

Ray Kurzweil argues that computing power has grown exponentially for about eighty years and will keep doing so. He expects AI to pass a rigorous Turing test (a test of whether a machine can pass as human) by 2029. He expects humans to merge with AI by the 2030s, leading to a 'singularity' in 2045, when our intelligence multiplies millions of times over.

The main tension is between his optimism and the dangers he admits. He says technology makes life better and cheaper for everyone, and that merging with AI beats being replaced by it. Yet he concedes risks from engineered viruses, nanobots that replicate out of control, nuclear war and misinformation. The talk ends on personal themes: his father, replicas of the dead, longevity, and love as life's meaning.

Key insights

  1. Kurzweil has held 2029 for Turing test since 1999

    He made the prediction in 1999 when AI experts polled at Stanford averaged a hundred years. Later polls moved to 2042, then 2030, which he says shows experts catching up to him.

  2. Computing growth predates Moore's law and Intel

    He says price-performance of computing has grown exponentially since the 1930s, passing from relays to vacuum tubes to transistors to integrated circuits. It continued through World War II and recessions, so he rejects the idea that it depends on any one chip technology.

  3. Large language models still fail multi-step reasoning

    He says they can sound convincing but struggle with chained reasoning, such as counting the legs of eleven elephants after handling ten. He thinks fixing this is needed before a valid, hours-long Turing test can be passed.

  4. Simulation could shrink drug development from years to days

    He cites Moderna's vaccine, saying billions of mRNA sequences were simulated in two days, with ten months going to testing. He expects simulated biology to speed testing as well, and to extend life expectancy.

  5. He sees merging with AI as the safe path

    He argues that people will connect their neocortex (the brain's thinking layer) to the cloud, likely using nanobots for high bandwidth. He believes this lets humans keep pace with AI rather than be replaced by it, and he expects the technology to become cheap like cell phones.

Questions

What is the technological singularity, and when does Ray Kurzweil say it will happen?

Kurzweil describes it as the point where computers change what we think is important and who we are, so human intelligence is multiplied millions of times and becomes hard to imagine. He still predicts it for 2045, the date he gave in The Singularity Is Near.

Does Kurzweil think AI will take everyone's jobs?

No. He points to a chart showing that income per person and the share of people working have gone up, because people use machines to boost their abilities. He admits this time could differ if humans do not merge with AI quickly enough.

How does Kurzweil think humans will merge with AI?

He expects that in the 2030s we will connect our neocortex, the part of the brain used for thinking, to the cloud. He says current devices like Neuralink are too slow and that nanobots, tiny machines inside the brain, would give the needed bandwidth.

What dangers does Kurzweil worry about?

He names nuclear war, an engineered virus that spreads silently and is highly lethal, misinformation on social networks, and the 'grey goo' problem of self-copying nanobots that could consume living things. He still thinks humanity will avoid disaster.

What does Kurzweil mean by longevity escape velocity?

It means extending life expectancy by more than one year for each year that passes, so people effectively outrun aging. He hopes this happens by the end of this decade, starting with people who are very diligent about their health.

Facts

Stated by the speakers. Each quote matches the transcript, which shows what was said, not that it is true.

Ray Kurzweil first predicted in his 1999 book The Age of Spiritual Machines that computers would pass the Turing test in 2029.

“I made this in 1999 in my book, The age of spiritual machines, and then you repeated the prediction in 2,000 in 2005.”

According to Ray Kurzweil, a 1999 Stanford conference polled AI experts on when AI would pass the Turing test, and the average answer was a hundred years.

“It was really the first time that AI experts worldwide were polled on this prediction. Uh, and the average poll was a hundred years.”

In the 1999 Stanford poll, 20 percent of AI experts said a machine would never pass the Turing test and 80 percent said it would happen but not in their lifetimes.

“Uh, 20% believed it would never happen. And that was the view in 1999. 80% believed it would happen, but not within their lifetimes.”

Ray Kurzweil says that a year before the interview, the forecasting platform Metaculus polled AI experts and gave 2042 for passing the Turing test, later revised to 2030.

“So a year ago, uh, something called Meticulous, which you may be aware of, assesses different types of experts on the future.”

Ray Kurzweil says language models worked poorly at around 10 billion parameters, worked fairly well at 100 billion, and were moving toward 1 trillion.

“it requires a certain amount of information in order to, uh, be effective, and that we would not see AI really being effective until it got to that level.”

Ray Kurzweil says AlphaFold predicted protein 3D shapes with near-100 percent success, where human experts managed perhaps 15 to 20 percent.

“human beings could do the best humans could maybe do fifteen, 20%, uh, of figuring out what the shape would be, and the this after a few takes it, uh, it ultimately did just about 100%.”

Chapters

  1. 0:07:23The singularity and the 2029 Turing test

    Kurzweil restates his 2045 singularity date and explains why he expects a hard Turing test to be passed in 2029. He covers expert polls and the limits of today's language models.

    “Singularity is where computers really change our view of what's important and change who we are.”
  2. 0:13:57Consciousness and machine ethics

    He says consciousness is a philosophical belief rather than a scientific fact, and that a machine passing the test would be taken as conscious by many.

    “if it really passes the Turing test, I would believe that it's conscious.”
  3. 0:20:52Brain-computer links and simulated biology

    He predicts neocortex-to-cloud connections in the 2030s and cites Moderna's vaccine and AlphaFold as proof that simulation speeds biology.

    “Another step then is in the twenty thirties, when we can actually connect our neocortex”
  4. 0:35:29Exponential growth of computing

    He shows eighty years of price-performance data and AI training compute doubling every six months, and argues this drives the 2045 prediction.

    “the exponential growth of computing is continuing, uh, and has never stopped.”
  5. 0:51:45Jobs, inequality and a better world

    He argues that automation has raised incomes, new technology gets cheap like cell phones, and measures such as poverty and life expectancy have improved.

    “I have fifty charts in there where everything is getting better.”
  6. 0:59:20Existential risks: viruses, nanobots, nuclear war

    He discusses the perils of advanced AI, bioengineered viruses, the 'great goo' nanobot scenario, and why he thinks nuclear war will be avoided.

    “it's the great goo challenge.”
  7. 1:04:21Replicas of his father and the afterlife

    He describes building a question-answering system from his father's writings and discusses ethical questions around digital replicants of the dead and the living.

  8. 1:10:07Origins, creativity and thinking backward

    He recounts his childhood fascination with a typewriter and offers advice to imagine your invention already exists and explain how you built it.

    “put yourself in the position that what you're trying to create already exists”
  9. 1:40:50Aliens, God, longevity and the meaning of life

    He doubts that aliens exist, defines God as love and consciousness, hopes to reach longevity escape velocity, and says love is life's meaning.

    “Love is the meaning of life.”

The following is a conversation with Ray Kurzweil, author, inventor, and futurist, who has an optimistic view of our future as a human civilization. Predicting that exponentially improving technologies will take us to a point of a singularity, beyond which super intelligent artificial intelligence will transform our world in nearly unimaginable ways. Eighteen years ago, in the book The Singularity Is Near, he predicted that the onset of the singularity will happen in the year twenty forty-five. He still holds to this prediction and estimate.

A lot of them are becoming good friends of mine. And it's just clear to me that running a company at every stage of it, from startup when it's just you, one founder or co-founder, to when it's many thousands of people, it's just so complicated.

0:02:49

There's so many things involved, so many more things than just the kind of engineering or the brainstorming or the idea development or product development, that kind of stuff. And that's the stuff I love, of course, but you have to get everything else right too. Like from from the human resource, from the hiring process, the hiring process alone is just so fascinating.

To support it, please check out our sponsors in the description. And now, dear friends, here's Ray Kurzweil. In your 2005 book titled The The Singularity Is Near, you predicted that the singularity will happen in twenty forty five. So now, eighteen years later, do you still estimate that the singularity will happen on, uh, twenty forty five?

0:07:23

And maybe first, what is the singularity, the technological singularity, and when will it happen? Singularity is where computers really change our view of what's important and change who we are. But we're getting close to some salient things that will change who we are. A key thing is 2029, when computers will pass the Turing test. And there's also some controversy whether the Turing test is valid. I believe it is. Most people do believe that, but there's some controversy about that.

0:08:17

But Stanford got very alarmed at my prediction about 2029. I made this in 1999 in my book, The age of spiritual machines, and then you repeated the prediction in 2,000 in 2005. Yeah,

0:08:17
Ray Kurzweil

five. So they held an international conference, you might have been aware of it, uh, of AI experts in 1999 to assess this view. So people gave different predictions and they took a poll. It was really the first time that AI experts worldwide were polled on this prediction. Uh, and the average poll was a hundred years. Uh, 20% believed it would never happen. And that was the view in 1999. 80% believed it would happen, but not within their lifetimes.

0:08:53

There's been so many advances in AI, uh, that the poll of AI experts has come down over the the years. So a year ago, uh, something called Meticulous, which you may be aware of, assesses different types of experts on the future. They again assessed what AI experts then felt, and they were saying twenty forty two for the Turing test, for the Turing test.

0:09:23
Lex Fridman

so it's coming down.

0:09:24
Ray Kurzweil

And I was still saying 2029 a few weeks ago. They again did another poll and it was twenty thirty. So, uh, AI experts now basically agree with me. I haven't changed at all. I've stayed with 2029. Um, and AI experts now agree with me, but they didn't agree at first

0:09:49
Lex Fridman

so Alan Turing formulated the Turing test, and

0:09:51
Ray Kurzweil

right now. What he said was very little about it. I mean, the 1950 paper where he had articulated the Turing test, he there's like a few lines that, uh, talk about the Turing test, um, and it really wasn't uh, very clear how to administer it. And he and he said, if, if they did it in like fifteen minutes, that would be sufficient, which I don't really think is is the case. These large language models now, some people are convinced by it already.

0:10:26

I mean, you can talk to it and have a conversation with, and you can actually talk to it for hours. Um, so it requires a little more depth. There's some problems with large language models, which we can talk about. Um, but some people are convinced by the Turing test. Now, if somebody passes the Turing test, w what? What are the implications of that? Does that mean that they're sentient, that they're conscious or or not? It's. It's not necessarily clear what the implications are anyway.

0:11:01

I I believe 2029, that's six, seven years from now. Uh, we'll have something that passes the Turing test and a valid Turing test, meaning it goes for hours, not just a few minutes.

0:11:16
Lex Fridman

can you speak to that a little bit? What is your formulation of the Turing test? You you've proposed a very difficult version of the Turing test. So what? What does that look like?

0:11:25
Ray Kurzweil

Basically, it's just to assess it over several hours. Um, and also have, uh, a human judge that's fairly sophisticated on what computers can do and can't do. Um, if you take somebody who's not that sophisticated, or even a a a average engineer, uh, they may not really assess various aspects of it.

0:11:52
Lex Fridman

So you really want the human to challenge the system on its ability to do things like common sense reasoning, perhaps?

0:12:01
Ray Kurzweil

That's actually a key problem with large language models. They don't do, uh, these kinds of, uh, tests that would involve assessing, uh, chains of reasoning. Um, but you can lose track of that. If you if you talk to them, they actually can talk to you pretty well, and you can be convinced by it. But it's somebody that would really convince you that it's a human, uh, whatever that takes. May maybe it would take days or weeks, um, but it would really convince you that it's human.

0:12:40

Um, large language models, uh, can appear that way. You can read conversations and they they appear pretty good. There are some problems with it. It doesn't do math very well. You can ask it, Well, how many legs did ten elephants have? and they'll tell you, Well, okay, each elephant has four legs, and it's ten elephants, so it's forty legs, and you go, Okay, that's pretty good. How how many legs do eleven elephants have? And it, uh, they don't seem to understand the question.

0:13:12
Lex Fridman

Do all humans understand that question?

0:13:14
Ray Kurzweil

No, that's the key thing. I mean, how advanced the human do you want it to be? But we do. We do expect a human to be able to do multi chain reasoning, uh, to be able to take a few facts and put them together, not perfectly. Uh, and we s. We see that, you know, in a lot of polls, that people don't do that perfectly at all. But um, so it's not. It's not very well defined, but it's it's something where it really would convince you that it's a human.

0:13:46
Lex Fridman

Is your intuition that large language models will not be solely the kind of system that passes the Turing test in 2029? Do we need something No, I think else?

0:13:57
Ray Kurzweil

no, I think it will be a large language model, but they have to go beyond what they're doing now. Uh, I think we're getting there. And and another key issue is if somebody actually passes the Turing test validly, I would believe they're conscious. Now, not everybody would say that. It's okay. We can pass the Turing test, but we don't really believe that it's conscious. That's a whole nother issue. Um, but if it really passes the Turing test, I would believe that it's conscious.

0:14:27

Uh, but I don't believe that of, uh, large language models today.

0:14:33
Lex Fridman

If it appears to be conscious, that's as good as being conscious, at least for you, in some, in some sense.

0:14:41
Ray Kurzweil

I mean, consciousness is not something that's scientific. Uh, I mean, I believe you're conscious, but it's really just a belief, and we believe that about other humans, that that at least appear to be conscious. Um, when you go outside of shared human assumption, uh, like, are animals conscious? Some people believe they're not conscious, some people believe they are conscious. And would a machine that acts just like a human be conscious? I mean, I believe it would be, but that.

0:15:17

But that's really a philosophical belief. It's not a you. You can't prove it. I can't take an entity and prove that it's conscious. There's nothing that you can do that would be that would indicate that.

0:15:30
Lex Fridman

It's like saying a piece of art is beautiful. You can say it, multiple people can experience a piece of art as beautiful, uh, but you can't prove it.

0:15:41
Ray Kurzweil

But it's also an extremely important issue. I mean, imagine if you had something with n nobody's conscious, uh, the the world may as well not exist. Um, and so some people, like, say, Marvin Minsky, um, said, Well, consciousness is not logical, it's not scientific, and therefore we should dismiss it. And and any ant any talk about consciousness is just not to be believed. But when he actually engaged with somebody who was conscious, he actually acted as if they were conscious.

0:16:23

He didn't ignore that

0:16:24
Lex Fridman

he acted as if consciousness does matter.

0:16:27
Ray Kurzweil

exactly, whereas he said it didn't matter.

0:16:30
Lex Fridman

Well, that's Marvin Minsky. He's full of contradictions.

0:16:34
Ray Kurzweil

but that's true of of a lot of people as well. Um,

0:16:38
Lex Fridman

But to you, consciousness matters.

0:16:40
Ray Kurzweil

but to me, it's it's very important. But, uh, but I would say it's not a scientific issue, uh, it's a philosophical issue, and people have different views. Uh, some people believe that anything that makes a decision is conscious, so your light switch is conscious. It's level of consciousness is low, it's not very interesting, but but that's a consciousness, uh, and anything. So a computer that makes a more interesting decision, still not at human levels, but it's also conscious and at a higher level than your light switch.

0:17:14

Uh, so that's one view. Uh, there's many different views of what consciousness is.

0:17:20
Lex Fridman

So if a system passes the Turing test, it's not scientific. But, uh, in issues of philosophy, things like ethics start to enter the picture. Do you think there would be? We would start contending as a human species about the ethics of turning off such a machine

0:17:44
Ray Kurzweil

Yeah, I mean, that's definitely come up, hasn't come up in reality yet, but

0:17:50
Lex Fridman

yet?

0:17:51
Ray Kurzweil

but I'm talking about 2029. It's not that many years from now. Um, and so what are our obligations to it? Uh, it has a different, I mean, a computer that's conscious is has a little bit different, uh, connotations than a human. Uh, we have a continuous consciousness. We're in an entity that, uh, does not last forever. Um, now, actually, a significant portion of humans still exist and are therefore still conscious. Um, but anybody who is over a certain age doesn't exist anymore.

0:18:37

That wouldn't be true of a computer program. You could completely turn it off, and and a copy of it could be stored, and you could recreate it, and so it has a different type of, uh, validity. Uh, you could actually take it back in time, you could eliminate its memory and have it go over again. I mean, it has a different kind of connotation than humans do.

0:19:02
Lex Fridman

Well, perhaps you can do the same thing with humans. It's just that we don't know how to do that yet. It's possible that we figure out all of these things on the machine first, but that doesn't mean the machine isn't conscious.

0:19:15
Ray Kurzweil

I mean, if you look at the way people react, say th three CPO or other, uh, machines that are conscious in movies, uh, they don't actually present how it's conscious. But we see that they are a machine, and people will believe that they are conscious, and they'll actually worry about it if they get into trouble and so on.

0:19:37
Lex Fridman

So 2029 is going to be the first year when a a major thing happens, and that that will shake our civilization to start to consider the role of AI Well, in.

0:19:50
Ray Kurzweil

yes and no. I mean, there's this one guy at Google who claimed that the machine was conscious,

0:19:58
Lex Fridman

But that's just one person. right? So When it starts to happen at scale,

0:20:03
Ray Kurzweil

well, that's exactly right, because most people have not taken that position. I don't take that position. I mean, I've used, uh, different things, um, uh, like this, and they don't appear to to me to be conscious. As we eliminate various problems of of these large language models, uh, more and more people will accept that they're conscious. So when we get to 2029, more, uh, I think a a large fraction of of people will believe that they're conscious.

0:20:39

Uh, so it's not going to happen all at once. Uh, I believe it will actually happen gradually, and it's already started to happen.

0:20:47
Lex Fridman

and so that, uh, takes us one step closer to the singularity.

0:20:52
Ray Kurzweil

Another step then is in the twenty thirties, when we can actually connect our neocortex, which is where we do our thinking, to computers. And I mean, J. Just as this actually gains a lot to being connected to computers that will amplify its abilities. I mean, if this did not have any connection, it it would be pretty stupid. It could not answer any of your questions.

0:21:22
Lex Fridman

If you're just listening to this, by the way, Ray's holding up the, uh, the all powerful, uh, smartphone.

0:21:30
Ray Kurzweil

So we're we're gonna do that directly from our brains. I mean, these are pretty good. These already have amplified our intelligence. I'm already much smarter than I would otherwise be if I didn't have this. Cause I remember when I first wrote The Age of Intelligent Machines, uh, there, there was no way to get, uh, information from computers. I actually would go to a library, find a book, find the page that had an information I wanted, and I'd go to the copier.

0:22:00

And my most significant, uh, information tool was a roll of quarters where I could feed the the copier. So we're already greatly advanced that we have these things. There's a few problems with it. First of all, I, I constantly put it down and I don't remember where I put it. I've actually never lost it, but um, you have to find it and then you have to turn it on. So there's a certain amount of steps. It would actually be quite useful if someone would just listen to your conversation and say, uh, oh, that's, you know, so and so actress, um, and tell you what you're talking about.

0:22:41
Lex Fridman

so going from active to passive, where it just permeates your whole life, the way your brain does when you're awake, your brain is always there.

0:22:51
Ray Kurzweil

right. Now, that's something that could actually just just about be done today. Where it would listen to your conversation, understand what you're saying, understand what you're, uh, not missing, and give you that information. But another step is to actually go inside your brain, uh, and there are some prototypes where you can connect your brain. They actually don't have the the amount of bandwidth that we need. They can work, but they work fairly slowly. So if if it actually would connect to your neocortex and the neocortex, which I describe in How to Create a Mind, uh, the neocortex is actually, uh, it has different levels, and as you go up the levels, it's kind of like a pyramid.

0:23:42

The top level is fairly small, and that's the level where you want to connect, uh, these brain extenders. Um, so I believe that will happen in the twenty thirties. We will actually g s. So just the way this is greatly amplified by being connected to the cloud, uh, we can connect our own brain to the cloud and, uh, just do what we can do by using this machine.

0:24:14
Lex Fridman

do you think it would look like, uh, the brain computer interface, uh, of like Neuralink? So would it be

0:24:20
Ray Kurzweil

Well, Neuralink is an attempt to do that. It doesn't have the bandwidth that we need. Um,

0:24:26
Lex Fridman

yet, right?

0:24:27
Ray Kurzweil

uh, right, but I I think, I mean, they're gonna get permission for this because there are a lot of people who absolutely need it because they can't communicate. And I know a couple of people like that who have ideas and they cannot, they don't, they cannot move their muscles and so on, they can't communicate. Uh, so f. For them, this would be very valuable, but we could all use it. Basically, it'd be, uh, turn us into something that would be like we have a phone, but it would be in our minds.

0:25:05

It would be kind of instantaneous.

0:25:07
Lex Fridman

And maybe communication between two people would not require this low bandwidth mechanism of language, of spoken word.

0:25:15
Ray Kurzweil

exactly, we. We don't know what that would be, although we do know the K, uh. Computers can share information like language instantly, they can share many, many books in a in a second, so we could do that as well. If you look at what our brain does, it actually can manipulate different parameters. So we we talk about these large language models. Um, I mean, I, I had written that, uh. It requires a certain amount of information in order to, uh, be effective, and that we would not see AI really being effective until it got to that level.

0:26:04

And we had large language models that were like 10 billion bytes. Didn't work very well. They finally got to 100 billion bytes, and now they work fairly well. And and now we're going to 1 trillion bytes. If you say, uh, lambda has a hundred uh billion bytes, what does that mean? Well, what? Uh, what if you had something that had one byte, one one parameter? Maybe you want to tell whether or not something's, uh, an elephant or not, and so you put in something that would detect its trunk.

0:26:38

If it has a trunk, it's an elephant, if it doesn't have a trunk, it's not an elephant. That would r work fairly well. There's a few problems with it, um, and it really wouldn't be able to tell what a trunk is. But anyway,

0:26:51
Lex Fridman

and maybe other things other than elephants have trunks. You might get really confused. I'm not sure which animals have trunks, but, you know, well, how do you define a trunk? But yeah, that's one parameter. You, you so could do okay,

0:27:06
Ray Kurzweil

these, so these things have 100 billion parameters, so they're able to deal with very complex issues.

0:27:12
Lex Fridman

all kinds of trunks.

0:27:14
Ray Kurzweil

Human beings actually have a little bit more than that, but they they're getting to the point where they can emulate humans. Um, if we were able to connect this to our, uh, neocortex, we would basically add more of these, uh, abilities to make distinctions, and it could ultimately b be much smarter and also be attached to information that w we feel is reliable. Um, so that's where we're headed,

0:27:45
Lex Fridman

So you think that there will be a a merger in the thirties, an increasing amount of merging between the the human brain and the AI brain.

0:27:56
Ray Kurzweil

exactly. And and the AI brain is really an an emulation of human beings. I mean, that's why we're creating them, because human beings act the same way, and this is basically to amplify them. I mean, this amplifies our brain. Um, it's a little bit clumsy to interact with, but it definitely, it's, you know, way beyond what w what we had fifteen years ago,

0:28:22
Lex Fridman

But the implementation becomes different, just like a bird versus the airplane. The even though the AI brain is an emulation, it starts adding features we might not otherwise have, like ability to consume a huge amount of information quickly, like look up thousands of Wikipedia articles in one take.

0:28:43
Ray Kurzweil

exactly. And we can get, for example, to issues like simulated biology, where you can, uh, simulate many different things at once. Um, I mean, we w. We already had one example of simulated biology, which is the Moderna vaccine, um, and and that's gonna be now the way in which we create, uh, medications. But they were able to simulate what each example of an mRNA would do to a human being, and they were able to simulate that quite reliably.

0:29:21

And we actually simulated billions of different mRNA sequences, and they found the ones that they were the best, and they created the vaccine, and they did and talk about doing it quickly. They did that in two days. Now, how long would a human being take to to simulate billions of different mRNA sequences? Uh, I don't know that we could do it at all, but it would take many years. They did it in two days. And one of the reasons that people didn't like vaccines is because it was done too quickly.

0:29:55

You know, it was done too fast. Uh, and they actually included the time it it took to test it out, which was ten months. So this is so they figured, okay, it took ten months to create this. Actually, it took us two days. And we also will be able to ultimately do the tests in a in a few days as well.

0:30:14
Lex Fridman

Oh, cause we can simulate how the body will respond to it more and more

0:30:17
Ray Kurzweil

now that's a little bit more complicated, cause the body's has a lot of different elements, and we have to simulate all of that. Uh, but that's coming as well. So ultimately, we could create it in a few days and then test it in a few days, and we'd be done. Uh, and we can do that with every type of medical ins, you know, insufficiency that we have. so curing all diseases, Yes, yeah,

0:30:43
Lex Fridman

um, improving f certain functions of the body, supplements, drugs for recreation, for health, for performance, for productivity, all that well, that's kind of stuff.

0:30:57
Ray Kurzweil

where we're headed. Cause, I mean, right right now, we have a very inefficient way of creating these new medications. Um, but we've already shown it, and the Moderna vaccine is actually the best, uh, of the of the vaccines we've had, uh, and it literally took two days to create, uh. And we'll get to the point where we can test it out also quickly.

0:31:20
Lex Fridman

Are you impressed by AlphaFold and, uh, the PR, the S solution to the protein folding, which, uh, essentially is simulating modeling this primitive building block of life, which is a protein and its three D shape?

0:31:36
Ray Kurzweil

It's pretty remarkable that they can actually predict what the three D shape of these things are. But they did it with the same type of neural net, the one, for example, the Go, uh, test.

0:31:51
Lex Fridman

So it's all the same,

0:31:53
Ray Kurzweil

It's all the same. I

0:31:54
Lex Fridman

all the same approaches.

0:31:54
Ray Kurzweil

mean, they, they took that same thing and just changed the rules to chess, and within a couple of days, it it now played a master level of chess greater than any human being. Um, and and the same thing then worked for AlphaFold, uh, which no human had done. I mean, human beings could do the best humans could maybe do fifteen, 20%, uh, of figuring out what the shape would be, and the this after a few takes it, uh, it ultimately did just about 100%.

0:32:33
Lex Fridman

Do you still think the singularity will happen in twenty forty five, and what does that look like?

0:32:40
Ray Kurzweil

You know, o, once we can amplify our brain with computers directly, which will happen in the twenty thirties, that's gonna keep growing. It's another whole theme, which is the exponential growth of computing power. Yeah,

0:32:55
Lex Fridman

Yeah, so looking at price, performance of computation from 1939 to 2021.

0:33:00
Ray Kurzweil

right. So that starts with the very first computer actually created by a German during World War II. And you might have thought that that might be significant, but actually, the Germans didn't think computers were significant, and they completely rejected it. And the second one was also the ZUSA two.

0:33:20
Lex Fridman

And by the way, we're looking at a plot with the X-axis being the year from 1935 to 2025. And on the Y-axis in log scale is competition per second per constant dollar, so dollar normalized to inflation. And it's growing linearly on the log scale, which means it's growing exponentially.

0:33:42
Ray Kurzweil

the third one was the British computer, uh, which the Allies did take very seriously, and it cracked the Ger, the German code, and enabled the British to win the Battle of Britain. Which otherwise absolutely would not have happened if they hadn't cracked the code using that computer. But that's an exponential graph, so a straight line on that graph is exponential growth, and you see eighty years of exponential growth. And I would say about every five years, and this happened shortly before the pandemic, people saying, Well, they call it Moore's law, which is n not the correct, because that's not all.

0:34:24

Intel, in fact, this started decades before Intel was even created, and wasn't with transistors formed into a grid.

0:34:34
Lex Fridman

So it's not just transistor count or transistor size, Right, I mean, they it's a bunch of they started with different components.

0:34:39
Ray Kurzweil

rel with relays, then went to vacuum tubes, then went to individual transistors, and and then to integrated circuits. Um, and I integrated circuits actually starts like in the middle of this graph, and it has nothing to do with Intel. Intel actually was a a key part of this, but a few years ago, they s they stopped making the fastest chips, uh. But if you take the fastest chip of any technology in that year, you get this kind of graph, and it's it.

0:35:17

It's definitely continuing for eighty years,

0:35:20
Lex Fridman

so you don't think Moore's law, broadly defined, is dead. It's been declared dead multiple times throughout this process.

0:35:29
Ray Kurzweil

I don't like the term Moore's law because it has nothing to do with Moore or with Intel. But yes, uh, the the exponential growth of computing is continuing, uh, and has never stopped.

0:35:43
Lex Fridman

from various sources.

0:35:44
Ray Kurzweil

I mean, it went through World War II, it went through global recessions, it's just continuing. Um, and if you continue that out along with software gains, which is a whole nother issue, um, and they really multiply whatever you get from software gains, you multiply by the computer gains, you get fast and faster speed. Uh, this is actually the fastest computer models that have been created, and that actually expands roughly twice a year, like every six months, it expands by two.

0:36:23
Lex Fridman

So we're looking at a plot from 2010 to 2022. On the X-axis is the publication date of the model and the perhaps sometimes the actual paper associated with it. And on the Y-axis is training compute in flops. And so basically, this is looking at the increase in the not transistors, but the computational power of neural networks,

0:36:52
Ray Kurzweil

Yes, the computational power that created these models, and that's doubled every six months.

0:36:58
Lex Fridman

which is even faster than transistor division.

0:37:02
Ray Kurzweil

and actually, since it goes faster than the the amount of cost, this has actually become a a greater investment to create these. But at any rate, by the time you get to twenty forty five, we'll be able to multiply our intelligence many millions fold. And it's just very hard to imagine what that will be like,

0:37:25
Lex Fridman

And that's the singularity, where we can't even imagine.

0:37:28
Ray Kurzweil

right? That's why we call it the singularity. It's a singularity in physics. Something gets sucked into a singularity and you can't tell what's going on in there because no information can get out of it. There's various problems with that, but that's the idea. It, it's too, uh, it's too much beyond what we can imagine.

0:37:49
Lex Fridman

Do you think it's possible? We don't notice that what the singularity actually feels like is we just live through it with exponentially increasing, uh, cognitive capabilities. And we almost, because everything's moving so quickly, don't aren't really able to introspect that our life has changed.

0:38:14
Ray Kurzweil

Yeah, but I mean, we will have that much greater capacity to understand things, so we should be able to look back.

0:38:21
Lex Fridman

looking at history, understand history,

0:38:23
Ray Kurzweil

But but we will need people, basically like you and me, to actually think about these

0:38:28
Lex Fridman

think about it. things. But we might be distracted by all the other sources of entertainment and fun, because the exponential power of intellect is growing. But also the

0:38:41
Ray Kurzweil

That'll be a lot of fun. Uh,

0:38:44
Lex Fridman

the the amount of ways you can have, you know,

0:38:46
Ray Kurzweil

I mean, we already have a lot of fun with computer games and so on, that are really quite remarkable.

0:38:52
Lex Fridman

what do you think about, uh, the digital world, uh, the metaverse, virtual reality? Will that have a component in this, or will most of our advancement be in physical reality?

0:39:02
Ray Kurzweil

Well, that's a little bit like Second Life, although the Second Life actually didn't work very well because it couldn't actually handle too many people. And I don't think the metaverse has come to being. I think there will be something like that. It it won't necessarily be from that one company. Th. I mean, there's gonna be C competitors, but yes, we're gonna live increasingly online, uh, and particularly when if our brains are online, I mean, how could we not be online?

0:39:32
Lex Fridman

Do you think it's possible that, given this merger with AI, most of our meaningful, uh, interactions will be in this virtual world? Most of our life? We fall in love, we make friends, we come up with ideas, we do collaborations, we have fun.

0:39:49
Ray Kurzweil

I actually know somebody who's marrying somebody that they never met. Uh, I think they just met her briefly before the wedding, but she actually, she actually fell in love with this other person, uh, never having met them. Uh, and I think it's, I think the love is real. So,

0:40:10
Lex Fridman

that's a beautiful story, but do you think that story is one that might be experienced as opposed to by hundreds of thousands of people, but instead by hundreds of millions of people?

0:40:22
Ray Kurzweil

I mean, it really gives you appreciation for these virtual ways of, uh, communicating, uh. And if anybody can do it, then it's really not such a a freak story, uh. So I think more and more people will do that.

0:40:38
Lex Fridman

But that's turning our back on our entire history of evolution, or the old days. We used to fall in love by holding hands and and sitting by the fire, that kind of stuff. Here Well, I you're, you're put

0:40:51
Ray Kurzweil

actually, I actually have five patents on where you can hold hands, even if you're separated. great. Um,

0:40:59
Lex Fridman

So the touch, the sense, it's all just senses, it's all just yeah, I mean, touch to be replicated.

0:41:04
Ray Kurzweil

is. It's not just that you're touching someone or not, there's a whole way of doing it, and it's very subtle. And but ultimately, we can emulate all of that.

0:41:18
Lex Fridman

Are you excited by that future? Do you worry about that future?

0:41:24
Ray Kurzweil

I have certain worries about the future, but not Not that virtual touch.

0:41:30
Lex Fridman

well, I agree with you. You described six stages in the evolution of information processing in the universe, as you started to describe. Can you maybe talk through some of those stages? From the physics and chemistry to DNA and brains, and then to the to the very end, to the very beautiful end of this process?

0:41:52
Ray Kurzweil

Well, it actually gets more rapid. So physics and chemistry, that's how we started. Um, So, so, from and we had,

0:42:01
Lex Fridman

the very beginning of the universe,

0:42:02
Ray Kurzweil

we had lots of electrons so and various things traveling around, and and that took actually many billions of years. Kind of jumping ahead here to kind of some of the last stages, where we have things like love and creativity. It's really quite remarkable that that happens. But finally, physics and chemistry created biology and DNA, and now you had actually one type of molecule that described the cutting edge of of this process. Um, and we go from physics and chemistry to biology, and finally, biology created brains.

0:42:48

I mean, not all, not everything that's created by biology has a brain, but eventually brains came along.

0:42:56
Lex Fridman

and all of this is happening faster and faster.

0:42:59
Ray Kurzweil

Yeah, it created an increasingly complex organisms. Another key thing is actually not just brains, but our thumb, uh, because th cause there's a lot of, uh, animals with brains even bigger than humans. I mean, elephants have a bigger brain, whales have a bigger brain, uh, but they've not created technology because they don't have a thumb. So that's o one of the really key elements in the evolution of humans,

0:43:34
Lex Fridman

this, uh, physical manipulator device that's useful for puzzle solving in the physical reality.

0:43:41
Ray Kurzweil

So I mean, I could think I could look at a tree and go, Oh, I could actually strip that branch down and eliminate the leaves and carve a t tip on it, and I would create technology. Uh, and you can't do that if you don't have a thumb. Um, so, uh, thumbs then created technology, and technology also, uh, had a memory, and now those memories are competing with the the scale and scope of human beings, and ultimately we'll go beyond it.

0:44:18

And then we're gonna merge human technology with, uh, with human intelligence, and understand how human, uh, intelligence works, which I think we already do, and we're putting that into, uh, our human technology.

0:44:39
Lex Fridman

So create the technology inspired by our own intelligence, and then that technology supersedes us in terms of its capabilities. And we ride along, or do you do you ultimately see it as

0:44:50
Ray Kurzweil

And and we ride along,

0:44:51
Lex Fridman

fucking?

0:44:51
Ray Kurzweil

but a lot of people don't see that. They say, well, okay, you've got humans and you got machines, and there's no way we can ultimately compete with humans. And you can already see that, uh, Lee Sedol, who's like the best Go player in the world, says he's not gonna play Go anymore. Because playing Go for human, that was like the ultimate in intelligence, because no one else could do that. Uh, but now a machine can actually go way beyond him.

0:45:22

And so he says, Well, there's no point playing it anymore.

0:45:25
Lex Fridman

that may be more true for games than it is for life. I think there's a lot of benefit to working together with AI in regular life. So if you were to put a probability on it, is it more likely that we merge with AI or AI replaces us?

0:45:44
Ray Kurzweil

A lot of people just think computers come along and they compete with them. We can't really compete, and that's the end of it, uh, as opposed to them increasing our abilities, and if you look at most technology, it it increases our abilities. Um, I mean, look at the history of work, uh, look at what people did a hundred years ago. Does any of that exist anymore? People, I mean, if you were to predict that all of these jobs would go away and would be done by machines, people would say, well, that's gonna be.

0:46:23

No one's gonna have jobs, and it's it's gonna be massive unemployment. Um, but I show in this book that's coming out, uh, the the amount of people that are working, even as a percentage of the population, has gone way up.

0:46:42
Lex Fridman

We're looking at the X-axis year from 1774 to 2024, and on the Y-axis, personal income per capita in constant dollars, and it's growing super linearly. I mean, it's

0:46:53
Ray Kurzweil

Yeah, 2021 constant dollars, and it's gone way up. That's not what you would predict, given that we would predict that all these jobs would go away. But the reason it's gone up is because we've basically enhanced our own capabilities by using these machines, as opposed to them just competing with us. That's a key way in which we're gonna be able to become far smarter than we are now by increasing the number of different parameters we can consider in making a decision,

0:47:27
Lex Fridman

I was very fortunate. I am very fortunate to be able to get a glimpse preview of your, uh, upcoming book, Uh, The Singularity Is Nearer. And, uh, one of the themes, outside of just discussing the increasing exponential growth of technology, one of the themes is that things are getting better in all aspects of life. And you talked just about, uh, uh, just about this. So one of the things you're saying is with jobs, so let me just ask about that.

0:47:58

There is a big concern that automation, especially powerful AI, will get rid of jobs, there, people will lose jobs. And as you were saying, the census throughout history of the twentieth century, automation did not do that ultimately. And so the question is, will this time be different?

0:48:21
Ray Kurzweil

right? That is the question, will will this time be different? And it really has to do with how quickly we can merge with this type of intelligence. Uh, whether Lambda GPT three is out there, and maybe it's overcome some of its, you know, key problems. Uh, and we really have an enhanced human intelligence, that might be a negative scenario. Um, but I mean, that's that's why we create technologies to enhance ourselves, uh, and I believe we will be enhanced.

0:48:59

We're not just gonna sit here with, uh, 300 million, uh, modules in our neocortex. We're gonna be able to go beyond that, um, because that's useful, but we can multiply that by ten, uh, hundred, thousand, a million. Um, and you might think, well, what's the point of doing that? It's like asking somebody that's never heard music, well, what? What's the value of music? I mean, you can't appreciate it until you've created it.

0:49:41
Lex Fridman

There's some worry that there will be a wealth disparity, you know, a class or wealth disparity. Only the rich people will be, basically, the rich people will first have access to this kind of thing. And then, because of this kind of thing, because the ability to merge will get richer exponentially faster.

0:50:03
Ray Kurzweil

and I say, that's just like cell phones. I mean, there's like 4 billion cell phones in the world today. In fact, when cell phones first came out, you had to be fairly wealthy. They weren't very inexpensive, so you had to have some wealth in order to afford them.

0:50:20
Lex Fridman

Yeah, there were these big, sexy, uh, And and phones,

0:50:23
Ray Kurzweil

and they didn't work very well, they did almost nothing. So you can only afford these things if you're wealthy at a point where they really don't work very well. So Um,

0:50:36
Lex Fridman

so achieving scale is, and, uh, making it inexpensive is part of making the thing work well.

0:50:42
Ray Kurzweil

exactly. So these are not totally cheap, but they're pretty, pretty cheap. Uh, I mean, you can get them for a few $100.

0:50:52
Lex Fridman

especially given the kind of things it provides for you. There's a lot of people in the third world that have very little, but they have a smartphone, and the same will be true with AI.

0:51:04
Ray Kurzweil

I mean, I see homeless people have their own cell phones, and

0:51:08
Lex Fridman

Yeah, so your sense is any kind of advanced technology will take the same trajectory.

0:51:15
Ray Kurzweil

right, it ultimately becomes cheap and will be affordable. Uh, I probably would not be the first person to put, uh, something in my brain to connect to computers, um, cause I think it will have limitations, but once it's really perfected, and at that point it'll be pretty inexpensive, I think it'll be pretty affordable.

0:51:40
Lex Fridman

So in in in which other ways, as you outline in your book, is life getting better? Cause I I think,

0:51:45
Ray Kurzweil

Well, I have, I mean, I have fifty charts in there where everything is getting better.

0:51:52
Lex Fridman

I think there's a kind of cynicism about, um, like, if, even if you look at extreme poverty, for example.

0:51:58
Ray Kurzweil

For example, th this is actually a poll taken on extreme poverty, and the people were asked, Has poverty gotten better or worse?

0:52:08
Lex Fridman

And the options are increased by 50%, increased by 25%, remain the same, decreased by 25%, decreased by 50%. If you're watching this or listening to this, try to m to try to vote for yourself.

0:52:21
Ray Kurzweil

70% thought it had gotten worse, and and that's the general impression. 88% thought it had gotten worse or it remained the same. Only 1% thought it decreased by 50%, and that is the answer. It actually decreased by 50%,

0:52:40
Lex Fridman

So only 1% of people got the right optimistic estimate of how, uh, poverty is.

0:52:45
Ray Kurzweil

right? And and and this is the reality, and it's true of almost everything you look at. You don't want to go back a hundred years or fifty years. Things were quite miserable then, but we tend not to remember that.

0:53:01
Lex Fridman

So literacy rate increasing over the past few centuries across all the different nations, nearly to 100% across many of the nations in the world,

0:53:12
Ray Kurzweil

It's gone way up, average years of education have gone way up, life expectancy is also increasing. Life expectancy was forty eight in 1,900,

0:53:24
Lex Fridman

and is over eighty now.

0:53:26
Ray Kurzweil

and it's gonna continue to go up, particularly as we get into more advanced stages of simulated biology.

0:53:33
Lex Fridman

For life expectancy, these trends are the same for at birth, age one, age five, age ten, so it's not just the infant mortality.

0:53:40
Ray Kurzweil

And I have fifty more graphs in the book about all kinds of things, uh, even spread of democracy, which might bring up s some sort of controversial issues. It still has gone way up,

0:53:55
Lex Fridman

Well, that one is, uh, it's gone way up, but that one is a bumpy road, right?

0:54:00
Ray Kurzweil

exactly. And some somebody might represent democracy and and go backwards. But we basically had no democracies before the creation of the United States, which is a little over two centuries ago, which, in the scale of human history, isn't that long.

0:54:17
Lex Fridman

Do you think superintelligent systems will help with democracy? So what is democracy? Democracy is giving a voice to the populace, and um, having their ideas, having their beliefs, having um, their views represented.

0:54:38
Ray Kurzweil

Well, I hope so. Uh, I mean, we've seen social networks can spread uh, conspiracy theories, uh, which have been quite negative being, for example, being against a any kind of stuff that would help your health.

0:54:58
Lex Fridman

So those kinds of ideas have, uh, on social media, what you notice is they increase engagement, so dramatic division increases engagement. Do you worry about AI systems that will learn to maximize that division?

0:55:17
Ray Kurzweil

I mean, I do have some concerns about this, um, and I co have a chapter in the book about the perils of advanced AI. Um, spreading misinformation on social networks is one of them, but uh, there there are many others.

0:55:37
Lex Fridman

What's the one that worries you the most that we should think about to try to avoid?

0:55:47
Ray Kurzweil

Well, it's it's hard to choose. Um, we do have the nuclear power that evolved when I was a child, I remember, and we would actually do these drills against a nuclear war. We'd get under our desks and put our hands behind our heads to protect us from a nuclear war. Seemed to work. We're still around. So, um,

0:56:16
Lex Fridman

You're protected?

0:56:17
Ray Kurzweil

but that's still a concern. And there are t dangerous situations that can, uh, take place in biology. Someone could create, uh, a virus that's very, I mean, we have viruses that are, uh, hard to spread, and they can be very dangerous, and we have viruses that are easy to spread, but they're not so dangerous. Um, somebody could create something that would be very easy to spread and very dangerous, and be very hard to stop. Uh, and it could be something that would spread without people noticing, cause people could get it, they'd have no symptoms, and then everybody would get it, and then symptoms would occur, maybe a month later.

0:57:12

So, I mean, uh, and that, and that actually doesn't occur normally, because if we were t t to, uh, have a problem with that, we wouldn't exist. So the fact that humans exist means that we don't have viruses that can spread easily and and kill us, because otherwise we wouldn't exist.

0:57:38
Lex Fridman

Yeah, viruses don't wanna do that, they want, they want to spread and keep the host alive somewhat.

0:57:44
Ray Kurzweil

so you, you can describe various dangers with biology, uh, also nanotechnology, uh, which we actually haven't experienced yet, but there are people that creating nanotechnology. And I described that in the book.

0:57:58
Lex Fridman

Now you're excited by the possibilities of nanotechnology, of nanobots, of being able to do things inside our body, inside our mind. That's going to help. What's exciting, what's terrifying about nanobots

0:58:11
Ray Kurzweil

What's exciting is that that's a way to communicate with our neocortex, because it's each neocortex is pretty small, and you need a small entity that can actually get in there and establish a communication channel. And that's gonna really be necessary to connect our brains to AI w within ourselves, because otherwise it would be hard for us to compete with it.

0:58:39
Lex Fridman

in a high bandwidth way?

0:58:40
Ray Kurzweil

Yeah, yeah, and that's key, actually, cause a lot of the things like Neuralink are are really not high bandwidth yet.

0:58:50
Lex Fridman

So nanobots is the way you achieve high bandwidth. How much intelligence would those nanobots have?

0:58:56
Ray Kurzweil

Yeah, they don't need a lot, uh, just enough to basically establish a communication channel to one nanobot. So,

0:59:04
Lex Fridman

So it's primarily about communication between external computing devices and our biological thinking machine. What worries you about nanobots? Is it similar to with the viruses?

0:59:20
Ray Kurzweil

well, I mean, it's the great goo challenge. Um, if you had, uh, a nanobot that, uh, wanted to create any any kind of entity and repeat itself and was able to operate in a natural environment, it could turn everything I into that entity and basically destroy all, uh, uh, biological life.

0:59:52
Lex Fridman

so you mentioned nuclear weapons. I'd love to hear your opinion about the 21st century and whether you think we might destroy ourselves. And maybe your opinion, if it has changed by looking at what's going on in Ukraine, that we could have a hot war with nuclear powers involved and the tensions building and a seeming forgetting of how terrifying and destructive nuclear weapons are. Do you think humans might destroy ourselves in the 21st century? And if we do, how?

1:00:36

And how do we avoid it?

1:00:39
Ray Kurzweil

I don't think that's gonna happen, despite the terrors of that war, it is a possibility. But I mean, I, I, I don't.

1:00:50
Lex Fridman

It's unlikely in your mind.

1:00:53
Ray Kurzweil

Yeah, even with the tensions we've had with this one, uh, nuclear power plant that's been taken over, um, it's very tense, but I don't actually see a lot of people worrying that that's gonna happen. I think we'll avoid that. We had two nuclear bombs go off in 45, so now we're seventy seven years later.

1:01:21
Lex Fridman

Yeah, we're doing pretty good,

1:01:22
Ray Kurzweil

We've never had another one go off through anger.

1:01:27
Lex Fridman

but people forget, people forget the lessons of history.

1:01:31
Ray Kurzweil

Well, yeah, so I I mean, I am worried about it. I mean that that is definitely a a a challenge,

1:01:37
Lex Fridman

But you believe that we'll make it out, and ultimately, superintelligent AI will help us make it out, as opposed to, uh, destroy us.

1:01:48
Ray Kurzweil

I think so, but we we do have to be mindful of these dangers, and and there are other dangers besides nuclear weapons. So

1:01:56
Lex Fridman

So, to get back to merging with AI, would we be able to upload our mind in a computer in a way where we might even transcend the constraints of our bodies? So copy our mind into a computer and leave the body behind?

1:02:17
Ray Kurzweil

let me describe one thing I've already done with my father,

1:02:21
Lex Fridman

That's a great story.

1:02:24
Ray Kurzweil

so we we created a technology. This is public came out, I think, six years ago, where you could ask any question, and the the release product, which I think is still on the market. Uh, it would read 200,000 books, and then, and and then find the one sentence in 200,000 books that best answered your question. Uh, and it's actually quite interesting, you can ask all kinds of questions, and you get the best answer in 200,000 books.

1:02:57

Um, but I was also able to to take it and, uh, not go through 200,000 books, but go through a book that I'd put together, which is basically everything my father had written, so everything he had written, I had gathered, and we created a book, everything that Frederick Israel had written. Now, I didn't think this actually would work that well because, uh, stuff he'd written was stuff about how to lay out. S. I mean, he did, uh, directed choral groups and music groups, and he would be laying out how people should, where they should s sit, and and uh, how to fund this and all, all kinds of things that really weren't didn't seem that interesting.

1:03:56

Um, and yet when you ask a question, it would go through it and it would actually give you a very good answer. So I said, Well, you know, who's the most interesting composer? and he said, Well, definitely Brahms. And he would go on about how Brahms was fabulous and talk about the importance of music education. And

1:04:18
Lex Fridman

so you could have a essentially a a

1:04:20
Ray Kurzweil

so I can have a

1:04:21
Lex Fridman

question and answer conversation with them.

1:04:22
Ray Kurzweil

can have a conversation with him, which was actually more interesting than talking to him. Because if you talk to him, he'd be concerned about how they're gonna lay out this property to give a choral group.

1:04:34
Lex Fridman

He'd be concerned about the day-to-day versus the big question. And you did ask about the meaning of life, and he answered, Love Do you miss him?

1:04:49
Ray Kurzweil

y, yes, I do. Um, you know, you get used to missing somebody after 52 years, and I didn't really have intelligent conversations with him until later in life. Um, in the last few years, he was sick, which meant he was home a lot, and I was actually able to talk to him about different things like music and other things. And, uh, so I, I miss that very much.

1:05:20
Lex Fridman

What did you learn about life from your father? What? What part of him is is with you now?

1:05:29
Ray Kurzweil

He was devoted to music, and when he would create something to music, it put him in a different world. Uh, otherwise, he was very shy, um, and if people got together, he tended not to interact with people just because of his shyness. But when he created music, that he, he was like a different person.

1:05:55
Lex Fridman

Do you have that in you, that that kind of light that shines?

1:06:00
Ray Kurzweil

I mean, I, uh, I got involved with technology at like, age five.

1:06:07
Lex Fridman

And you fell in love with it in the same way he did with music.

1:06:09
Ray Kurzweil

Yeah, yeah, I remember this actually happened with my grandmother, she had a a manual typewriter, and she wrote a book, one life is not enough, which is actually a good title for a book I might write. But and it was about a school she had created. Well, actually, her mother created it, so my mother's mother's mother created the school in 1868, and it was the first school in Europe that provided higher education for girls. It went through 14th grade.

1:06:46

If you were a girl and you were lucky enough to get an education at all, it would go through like 9th grade, and many people didn't have any education as a girl. Uh, this went through 14th grade. Um, her mother created it, she took it over, and the and the book was about, uh, the history of the school and her involvement with it. Um, when she presented to me, I was not so interested in the story of the book of the school, but I was totally amazed with this manual typewriter.

1:07:25

I mean, here is something you could put a blank piece of paper into and you could turn it l into something that looked like it came from a book and you could actually type on. And it looked like it came from a book. It was just amazing to me and I could see actually how it worked, and I was also interested in magic, um, but in magic, if somebody actually knows how it works, the magic goes away, the magic doesn't stay there.

1:07:54

If you actually understand how it works, but here was technology. I didn't have that word when I was five or six,

1:08:01
Lex Fridman

and the magic was still there for you.

1:08:03
Ray Kurzweil

the magic was still there, even if you knew how it worked. So I became totally interested in this and then went around, collected little pieces of mechanical objects, from bicycles, from broken radios. I would go through the neighborhood. Uh, this was an era where you would allow a five or six year old to like, roam through the neighborhood and do this. We don't of course, do that anymore. But but I didn't know how to put them together.

1:08:31

I said, if I could just figure out how to put these things together, I could solve any problem. And I actually remember talking to these very old girls, I think they were ten, um, and t telling them I if I could just figure this out, I we could fly, we could do anything. And they said, Well, you, you have quite an imagination, um, and then I get, then when I was in 3rd grade, so I was like eight, created like a virtual reality theater where people could come on stage and they could move their arms.

1:09:10

And all of it was controlled through one control box. It was all done with mechanical technology, and it was a big hit in my 3rd grade class. And then I went on to do things in junior high school science fairs and and and high school science fairs, where I won the Westinghouse Science Talent Search. So, I mean, I became committed to technology when I was five or six years old.

1:09:39
Lex Fridman

you've talked about how you use, uh, lucid dreaming to think, to come up with ideas as a source of creativity. Could you maybe talk through that? Maybe the process of how to? You've invented a lot of things, you've came up and thought through some very interesting ideas. What advice would you give? Or how can you speak to the process of thinking, of how to think, how to think creatively?

1:10:07
Ray Kurzweil

Well, I mean, sometimes I, I will think through in a dream and try to interpret that. But I think the key issue that I would tell younger people, um, is to put yourself in the position that what you're trying to create already exists, and then you're explaining like, uh,

1:10:35
Lex Fridman

How it works? e- exactly That's really interesting. You paint the world that you would like to exist, you think it exists, and reverse engineer and and then you that.

1:10:46
Ray Kurzweil

actually imagine you're giving a speech about how you created this. Well, you'd have to then work backwards as to, h, how, how you would create it in order to make it work.

1:10:57
Lex Fridman

that's brilliant, and that requires, uh, s some imagination, too, some first principles thinking. You have to visualize that world, that's really interesting.

1:11:08
Ray Kurzweil

And generally, when I talk about things we're trying to invent, I would use the present tense as if it already exists. Not just to give myself that that confidence, but everybody else who's working on it. Um, we just have to, kind of, uh, do all the steps in order to make it, uh,

1:11:29
Lex Fridman

How much?

1:11:29
Ray Kurzweil

act actual.

1:11:31
Lex Fridman

How much of a good idea is about timing? How much is it about your genius? Versus th that the it's time has come?

1:11:42
Ray Kurzweil

Timing's very important. I mean that that's really why I got into futurism. I'm not, I didn't, I wasn't inherently a futurist. That that's not really my goal. Uh, it's really to to figure out when things are feasible. We we see that now with large scale models, they're very f large scale models, like GPT three. It started two years ago, four years ago, it wasn't feasible. In fact, they did create, uh, GPT two, uh, which didn't work.

1:12:18

Uh, so it required a certain amount of timing, having to do with this exponential growth of of of computing power.

1:12:27
Lex Fridman

So futurism, in some sense, is a study of timing, trying to understand how the world will evolve and when will the capacity for certain ideas. M

1:12:38
Ray Kurzweil

and and that's become a thing Emerged. in itself. And to try to time things in the future. Uh, but really, its our original purpose was to time. My products. I mean, I did OCR in the 1970s, uh, because OCR is, uh, doesn't require a lot of computation.

1:13:01
Lex Fridman

Optical character recognition.

1:13:03
Ray Kurzweil

Yeah, so we were able to do that in the 70s, and I waited till the 80s to to address speech recognition, since that requires, uh, more computation.

1:13:14
Lex Fridman

So you were thinking through timing when you're developing those things, has its time come. And that's how you've developed that brain power to start to think in a futurist sense. When, how will the world look like in 2045? And work backwards and how it gets there?

1:13:34
Ray Kurzweil

But that has become a thing in itself, because looking at what, uh, things will be like in the future reflects such dramatic changes in in how humans will live. Uh, that was worth communicating. Also,

1:13:51
Lex Fridman

So you develop that muscle of of predicting the future and then apply it broadly and start to discuss how it changes the world of technology, how it changes the world of human life on earth. In Danielle, one of your books, you write about someone who has the courage to question assumptions that limit human imagination to solve problems. S And you also give advice on how each of us can have this kind of, um, courage.

1:14:23
Ray Kurzweil

well, it's good that you picked that quote because I think that that symbolized what Danielle is about.

1:14:27
Lex Fridman

Courage. So how can each of us have that courage to quest? Question assumptions?

1:14:34
Ray Kurzweil

I mean, we see that when people can go beyond the current realm and and create something that's new. I mean, take Uber, for example, before that existed, y, you never thought that that would be feasible, and it did require changes in the way people work.

1:14:55
Lex Fridman

Is there practical, uh, advices you give in the book about each, what each of us can do to be a Danielle?

1:15:05
Ray Kurzweil

Well, she looks at at the situation and tries to imagine, uh, how she can overcome various obstacles, and then she goes for it. And she's a very good communicator, so she can communicate these ideas to other people.

1:15:25
Lex Fridman

And there's practical advice of learning to program and recording your life and things of this nature. Become a physicist. So you list a bunch of different, uh, suggestions of how to throw yourself into this world.

1:15:39
Ray Kurzweil

yeah, I mean, it's kind of a idea how young people can actually change the world by, uh, learning all of these different skills.

1:15:52
Lex Fridman

And at the core of that is the belief that you can change the world, that your mind, your body can change the world. yeah, that's right, And not letting anyone else tell you otherwise. that's very good. Exactly, When we upload, the the story you told about your dad and having a conversation with him, we're talking about uploading your mind to the computer. Do you think we'll have a future with something you call, uh, afterlife? We'll have avatars that mimic increasingly better and better our behavior, our appearance, all that kind of stuff.

1:16:34

Even those are perhaps not no longer with us.

1:16:37
Ray Kurzweil

yes. I mean, w we need some information about about them. I mean, I think about my father, I have what he wrote. Now. He didn't have a word processor, so he didn't actually write that much, and our memories of him aren't perfect. So how do you even know if you've created something that's satisfactory? You know, you could do a RA. a Frederick Kurzwell Turing test. He seems like Frederick Kurzwell to me, but the people who remember him, like me, don't have a perfect memory.

1:17:14
Lex Fridman

Is there such a thing as a perfect memory? Maybe the whole point is for him to make you feel a certain way,

1:17:26
Ray Kurzweil

Yeah, well, I think that would be the goal.

1:17:28
Lex Fridman

and that's the connection we have with loved ones. It's not really based on very strict definition of truth, it's more about the experiences we share and they get morphed through memory, but ultimately they make a smile.

1:17:42
Ray Kurzweil

I think we we could definitely can do that, and that would be very worthwhile.

1:17:47
Lex Fridman

So do you think we'll have a world of replicants of copies? Would there be a bunch of Ray Kurzweils? Like I could hang out with one? I can download it for five bucks and have a best friend, Ray, and, uh, you, the original copy, wouldn't even know about it. Is that? is that? Do you think that world is, um, first of all, do you think that world is feasible? And do you think there's ethical challenges there?

1:18:16

Like, how would you feel about me hanging out with Ray Kurzweil and you not knowing about it?

1:18:22
Ray Kurzweil

uh, doesn't strike, uh, me as a problem. Um, Which which you, the would would

1:18:30
Lex Fridman

original?

1:18:30
Ray Kurzweil

you? Stri? Would that cause a problem for you? No, I, So

1:18:35
Lex Fridman

I enjoy, I would really, very much enjoy it.

1:18:37
Ray Kurzweil

no, not just hang out with me, but if somebody hang out with you, a a replicant of you,

1:18:44
Lex Fridman

Well, I think I would start. It sounds exciting, but then what if they, uh, start doing better than me? And s and take take over my friend group? And then, and then I, because because they may be, um, an imperfect copy, or they're maybe more social, all these kinds of things. And then I become like the old version, that's not not nearly as exciting. Maybe they're a copy of the best version of me on a good day.

1:19:13
Ray Kurzweil

yeah. But if you hang out with a replicant of me and that turned out to be successful, I'd I'd feel proud of that person, cause it was based on me. So

1:19:25
Lex Fridman

So it's it, but it is a kind of death of this version of you,

1:19:32
Ray Kurzweil

well, not necessarily. I mean, you can still be alive, right?

1:19:36
Lex Fridman

but and you would be PR, okay? So it's like having kids, and you're proud that they've done even more than you were able to do. Hm,

1:19:48
Ray Kurzweil

uh. It does bring up new issues, but, uh, it seems like an opportunity.

1:19:55
Lex Fridman

well, that that replicant should probably have the same rights as you do.

1:20:00
Ray Kurzweil

Well, that, uh, that gets into a whole issue, uh, because when a replicant occurs, they're not necessarily gonna have your rights. And if a replicant occurs to somebody who's already dead, do they have all the obligations and that the original person had? Do they have all the agreements that they had? And, uh, so

1:20:26
Lex Fridman

I think you're gonna have to have laws that say yes, there has to be. If you wanna create a replicant, they have to have all the same rights as human rights.

1:20:36
Ray Kurzweil

well, you, you don't know. Someone could create a replicant, say, well, it's a replicant, but I didn't bother getting their rights. And so

1:20:42
Lex Fridman

But that would be illegal. I mean, like, if you do that, you have to do that on the black market, you have to, if you wanna get an official replicant,

1:20:49
Ray Kurzweil

okay, it's not. It's not so easy. Supposed to create multiple replicants. Uh, the original rights, uh, maybe for one person and not for a whole group of per people. And

1:21:05
Lex Fridman

sure. So, uh, so there has to be at least one, and then all the other ones kind of share the rights. Yeah, I, I just don't. I don't think that that's very difficult to conceive for us humans, the the the idea I mean, of destruction.

1:21:20
Ray Kurzweil

we don't. You could create a replicant that has certain. I mean, I've talked to people about this, including my wife, who would l like to get back her father. Um, and she doesn't worry about, uh, who has rights to what? She? She would have somebody that she could visit with and like, give her some satisfaction, uh, and they wouldn't. She wouldn't care about any, any of these other rights.

1:21:49
Lex Fridman

What does your wife think about multiple Ray Kurzweils? I haven't Have you had that discussion?

1:21:55
Ray Kurzweil

I haven't addressed that with him.

1:21:58
Lex Fridman

I th. I think ultimately that's an important question. Loved ones, how they feel about, there's, uh, there's something about love,

1:22:05
Ray Kurzweil

Well, that's the key thing, right? If if the loved one's rejected, it's not gonna work very well. So so the loved ones really are the key determinant whether or not this works or not.

1:22:20
Lex Fridman

but there's also ethical rules. Um, we have to contend with idea, and we have to contend with that idea with AI.

1:22:28
Ray Kurzweil

But but what's gonna motivate it is, I mean, I talk to people who really miss people who are gone and they would love to get s something back, even if it's isn't perfect. Uh, and that's what's gonna motivate this,

1:22:47
Lex Fridman

and that person lives on in some form, and is, uh. The more data we have, the more we're able to reconstruct that person and allow them to live on.

1:22:58
Ray Kurzweil

right? And, uh, eventually, as we go forward, we're gonna have more and more of this data. Because we're gonna have nanobots that are inside our neocortex, and we're gonna collect a lot of data. In fact, anything that's data is is always collected

1:23:16
Lex Fridman

There is something a little bit sad, which is becoming, or maybe it's hopeful, which is more and more common these days. Which when a person passes away, you'll have their Twitter account, you know, and you have the last tweet they tweeted, like something they and you can tweeted that day.

1:23:36
Ray Kurzweil

recreate them now with large language models and so on. I mean, you can create somebody that's just like them and can actually continue to, uh, communicate.

1:23:45
Lex Fridman

I think that's really exciting because I think, in some sense, like, if I were to die today, in some sense, I would continue on if I continued tweeting. I tweet, therefore I am Yeah, well, I, in some I, I'm. I mean, sense.

1:24:01
Ray Kurzweil

that's one of the advantages of a replicant. They can recreate the communications of that, that person.

1:24:10
Lex Fridman

Do you hope? Do you think? Do you hope humans will become a multiplanetary species? You've talked about the phases, the six epochs, and one of them is reaching out into the stars. In part,

1:24:24
Ray Kurzweil

Yes, but, uh, the kind of attempts we're making now to go to other s planetary objects doesn't excite me that much, cause it's not really advancing anything. it's not Uh,

1:24:40
Lex Fridman

efficient enough.

1:24:41
Ray Kurzweil

yeah, we're. And we're also putting out other, uh, human beings, which is a very inefficient way to explore these other objects. What I'm really talking about in the L in the sixth epoch, the universe wakes up. It's where we can spread our super intelligence throughout the universe, and that doesn't mean s sending very soft, squishy creatures like humans.

1:25:10
Lex Fridman

Yeah, the universe wakes up.

1:25:14
Ray Kurzweil

I mean, we, we would send intelligence, masses of nanobots, which can then go out and, um, colonize these these other parts of the universe.

1:25:29
Lex Fridman

Do you think there's intelligent alien civilizations out there that our bots might meet?

1:25:35
Ray Kurzweil

My hunch is no. Most people say, yes, absolutely, I mean, and and the Universe is and they'll,

1:25:43
Lex Fridman

too big.

1:25:43
Ray Kurzweil

and they'll cite the Drake equation, and and I think in, Uh, The Singularity Is Near. Um, I have two analyses of the Drake equation, both with very reasonable assumptions, and one gives you thousands of s advanced civilizations in each galaxy, and another one gives you one civilization. And we know of one. A lot of the analyses are forgetting the exponential growth of of of computation. Because we've gone from where the fastest way I could send a message to somebody was with a pony, which was what, like, uh, a century and a half ago, uh, to the advanced civilization we have today.

1:26:38

And and and if you accept what I've said, go forward a few decades, you can have absolutely fantastic amount of civilization compared to a pony. And that's in a a couple hundred years,

1:26:50
Lex Fridman

yeah. The speed and the scale of information transfer is just exp- is growing exponentially so in a blink of an eye.

1:26:59
Ray Kurzweil

now think about these other civilizations. Uh, they're gonna be spread out at at cosmic times. So if something is like ahead of us or behind us, it could be ahead of us or behind us by maybe millions of years, which isn't that much. I mean, the the the world is billions of years old, 14 billion or something, so even a thousand years. If if two or 300 years is enough to go from a pony to fantastic amount of civilization, we would see that.

1:27:36

So, uh, of other civilizations that have occurred, okay, some might be hi behind us, but some might be ahead of us. If they're ahead of us, they're ahead of us by thousands, millions of years, and they would be so far beyond us, they would be doing galaxy-wide engineering. But we don't see anything doing galaxy-wide engineering.

1:28:00
Lex Fridman

so either they don't exist, or this very universe is a construction of an alien species. We're living inside a video game.

1:28:12
Ray Kurzweil

Well, that's another explanation that, yes, uh, you've got some teenage kids in another civilization.

1:28:17
Lex Fridman

and basically, do you do you find compelling the simulation hypothesis as a thought experiment that we're living in a simulation?

1:28:26
Ray Kurzweil

The universe is computational, so we are an example in a computational world. Therefore, uh, it is a simulation. It doesn't necessarily mean an experiment by some high school kid in another world, but it's nonetheless is taking place in a computational world. And everything that's going on is is basically a form of of computation. Um, s, so you really have to define what you mean by, uh, this, this whole world being a simulation.

1:29:06
Lex Fridman

Well, then it's the it's the teenager that that makes the video game, you know, us humans, with our current limited cognitive capability, have, um, strived to understand ourselves, and we have created religions. We think of God, whatever that is. Do you think God exists? and if so, who is God?

1:29:35
Ray Kurzweil

I alluded to this before we. We started out with lots of particles going around and there's nothing that represents love and creativity. Um, and somehow we've gotten into a world where love actually exists, and that has to do actually with consciousness, because you can't have love without consciousness. So to me, that's God, the fact that we have something where love, where you can be devoted to someone else and and really feel that love. Um, that's, that's God.

1:30:19

And if you look at the Old Testament, it was actually created by several different ra rabbinets in in there. And I think they've identified three of them. One one of them dealt with God, uh, as a person that you can make deals with, and he gets angry, and he wreaks rev- uh, vengeance on various people. But two of them actually talk about God as a a symbol of love and peace and harmony and and so forth.

1:30:58

Uh, that's how they describe God, and so that's my view of God. Not not as a person in the sky that that you can make deals with.

1:31:09
Lex Fridman

it's whatever the magic that goes from basic elements to things like consciousness and love. Do you think one of the things I find extremely beautiful and powerful is cellular automata, which you also touch on? Do you think whatever the heck happens in cellular automata, where interesting, complicated objects emerge? God is in there, too. The emergence of love in this seemingly primitive Well, that's the goal universe.

1:31:38
Ray Kurzweil

of of of creating a replicant is that they would love you and you would love them. There wouldn't be much point of doing it if that didn't happen.

1:31:53
Lex Fridman

But all of it, I guess what I'm saying about cellular automata is it's, uh, primitive building blocks, and they somehow create beautiful things. Is there some deep truth to that about how our universe works? Is the the emergence from simple rules, beautiful, complex objects can emerge? Is that the thing that made us Yeah, well, as we went through all the six phases of reality?

1:32:22
Ray Kurzweil

that's a good way to look at it. It just makes some point to the whole value of having a universe.

1:32:31
Lex Fridman

Do you think about your own mortality? Are you afraid of it?

1:32:36
Ray Kurzweil

Yes, but I I keep going back to my, uh, idea of being able to expand human life quickly enough, uh, in advance of our getting there. Longevity escape velocity, um, which we're not quite at yet, but I think we're actually pretty close. Uh, particularly with, for example, doing simulated biology, uh, I think we can probably get there within, say, by the end of this decade, and that's my goal.

1:33:13
Lex Fridman

Do you hope to achieve the longevity escape velocity? Do you hope to achieve immortality?

1:33:21
Ray Kurzweil

Well, immortality is hard to say. I I can't really come on your program saying I've done it, I've achieved immortality because it's never forever. Um, but.

1:33:32
Lex Fridman

a long time, a long time of living well.

1:33:35
Ray Kurzweil

But we'd like to actually advance human life expectancy, advance my life expectancy more than a year every year, and I think we can get there within by the end of this decade.

1:33:48
Lex Fridman

How do you think we'd do it? So there's practical things, um, and transcend the nine steps to living well forever. Your book, you describe just that there's practical things like health, exercise, all those things, and is there a certain

1:34:02
Ray Kurzweil

I mean, we live in a body that doesn't last forever. There's no reason why it can't, though, and we're discovering things. I think that will extend it. Um, and but you do have to deal with. I mean, I've got various issues. Went to Mexico 40 years ago, developed salmonella that created pancreatitis, which gave me a strange form of diabetes. Um, it's not, uh, type one diabetes, cause that's an autoimmune disorder that destroys your pancreas. I don't have that, but it's also not type two diabetes, cause type two diabetes, it's your pancreas works fine, but your cells don't absorb the insulin well.

1:34:56

I don't have that either. Uh, the pancreatitis I had, uh, partially damaged my pancreas, but it was a one-time thing, it didn't continue, um, and I've learned now how to control it. But so that's just something I had to do, uh, in order to continue to exist.

1:35:19
Lex Fridman

since your particular biological system? You have to figure out a few hacks, and the idea is that science will be able to do that much better. Actually,

1:35:26
Ray Kurzweil

yeah. So I mean, I, I do spend a lot of time just tinkering with my own body to keep it going. Uh, so I do think I'll last till the end of this decade, and I think we'll achieve longevity escape velocity. I think that will start with people who are very diligent about this. Eventually, it'll become sort of routine, that that people will be able to do it. So if you're talking about kids today, or even people in their 20s or 30s, it it's really not a a a very serious problem.

1:36:01

I have had some discussions with relatives who are like almost a hundred and saying, well, we're working on it as quickly as possible, but I don't know if that's gonna work.

1:36:16
Lex Fridman

is there a case? This is a difficult question, but is there a case to be made against living forever? That a finite life, that mortality is a feature, not a bug, that that living Well, a shorter t. So dying makes ice cream taste delicious, makes life intensely beautiful. More than, uh, yeah, most people otherwise, maybe.

1:36:43
Ray Kurzweil

believe that way, except if you present a death of anybody they care about or love, they find that extremely depressing. And I know people who feel that way. Twenty, thirty, forty years later, they still want them back. Um, so, I mean, death is not something to celebrate, but we've lived in a world where people just accept this. Life is short, you see it all the time on TV. Ah, life is short, you have to take advantage of it.

1:37:21

And nobody accepts the fact that you could actually go beyond normal lifetimes. But any time we talk about death, or death of a person, even one death is a terrible tragedy. If you have some body that lives to a hundred years old, we still love them in in return, and there's no limit, l limitation to that. In fact, these kinds of, uh, trends are gonna provide greater and greater opportunity for everybody, even if we have more people.

1:37:57
Lex Fridman

So let me ask about an alien species or a superintelligent AI 500 years from now that will look back. And, uh, remember Ray Kurzweil version zero, the uh, before the replicants spread. Uh. W How do you hope they remember you in a um hitchhiker's guide to the galaxy? Summary of Ray Kurzweil, What do you hope your legacy is?

1:38:24
Ray Kurzweil

Well, I mean, I do hope to be around, so that's

1:38:27
Lex Fridman

Some version of you? Yes, so. Um, do you think you'll be the same person around?

1:38:32
Ray Kurzweil

I mean, am I the same person I was when I was That's true, exactly, 20 or ten? Or,

1:38:37
Lex Fridman

You would be the same person in that same way, but yes, we're different, we're different. All we have of that, all you have of that person, is your memories, which are probably, um, distorted in some way. Maybe you just remember the good parts, depending on your psyche, you might focus on the bad parts, might focus on the good parts.

1:39:03
Ray Kurzweil

right? But, uh, I mean, I'd still have a relationship to the way I was when I was earlier, when I was younger.

1:39:12
Lex Fridman

How will you and the other super intelligent AIs remember you of today from 500 years ago? What do you hope to be remembered by? This version of you before the singularity?

1:39:26
Ray Kurzweil

Well, I think it's expressed well in my books, trying to create some new realities that that people will accept. I mean, that's something that gives me great pleasure, um, and great greater insight into what what makes humans, uh, valuable. I'm not the only person who's, uh, attempted to comment on that, but

1:39:57
Lex Fridman

And, uh, optimism that permeates your work, optimism about the future is ultimately that optimism paves the way for building a better future.

1:40:07
Ray Kurzweil

yeah, no, I, I, I agree with that.

1:40:10
Lex Fridman

So you, uh, asked your dad about the meaning of life, and he said, Love, let me ask you the same question, What's the meaning of life? Why are we here? This beautiful journey that we're on in phase four, reaching for phase five of this evolution and information processing. Why?

1:40:35
Ray Kurzweil

Well, I think I'd give the same answer as as my father. Um, because if there were no love and we didn't care about anybody, there'd be no point existing.

1:40:50
Lex Fridman

Love is the meaning of life. The AI version of your dad had a good point. Well, I think that's a beautiful way to end it, right? Thank you for your work, thank you for being who you are, thank you for dreaming about a beautiful future and, uh, creating it, uh, along the way. And thank you so much for, uh, spending your really valuable time with me today. This was awesome.

1:41:12
Ray Kurzweil

Well, it was my pleasure, and, uh, you have some great insights, both into me and into humanity as well, so I appreciate that.

1:41:21
Lex Fridman

Thanks for listening to this conversation with Ray Kurzweil. To support this podcast, please check out our sponsors in the description. And now let me leave you with some words from Isaac Asimov. It is change, continuous change, inevitable change that is the dominant factor in society today. No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be. This, in turn, means that our statesmen, our businessmen, our every man must take on a science fictional way of thinking.

1:42:00

Thank you for listening and hope to see you next time.
