Starting point is 00:00:00 Welcome to StarTalk, your place in the universe where science and pop culture collide. StarTalk begins right now. Hello, good evening. I'm Susan Engel and I have the privilege of being the director of 92nd Street Y Talks. Tonight's event is part of our third annual Seven Days of Genius Festival, which invites leading thinkers to explore all aspects of genius, how we define it, how it emerges across communities and cultures, why it matters, and what the future of genius looks like. Neil deGrasse Tyson is an astrophysicist at the American Museum of Natural History and the Frederick P. Rose
Starting point is 00:01:02 director of the Hayden Planetarium at the Museum of Natural History. Please join me in welcoming to this stage Dr. Neil deGrasse Tyson. Thank you all for coming out. You come here to watch a conversation I'm about to have with the one and the very much only Ray Kurzweil. Ray, I've got his bio here and I'll read his bio and it just it's just stunning that he walks among us and so that someone such as he is there saving us from ourselves
Starting point is 00:01:45 and leading us into the future with the guiding light of wisdom, science, and technology. So he's one of the world's leading inventors, thinkers, and perhaps most importantly, futurists. And he's got a 30-year track record of accurate predictions. We will double verify that this evening. I want to know what predictions he swept under the rug that we didn't hear about later. And he's been called the restless genius by the Wall Street Journal.
Starting point is 00:02:16 That's the best kind, by the way. And the ultimate thinking machine by Forbes magazine. And he was selected as one of the top entrepreneurs by Inc. magazine. I-N-C. There's a separate one for pen lovers called I-N-K. That's not the one. Which described him as the rightful heir to Thomas Edison,
Starting point is 00:02:36 one of the most famous of the restful geniuses in our history books. PBS selected him as one of the 16 revolutionaries who made America. He was the principal inventor of the first CCD flatbed scanner, the first omniphon optical character recognition, the first print-to-speech reading machine for the blind, the first text-to-speech synthesizer,
Starting point is 00:03:03 the first music synthesizer capable of recreating a grand piano and other orchestral instruments, and the first commercially marketed large vocabulary speak recognition. All this is software. Somebody's got to do it. He did it. Somebody's got to do it first. He did it first. Among his many honors, he's received the 2015 Technical Grammy Award for Outstanding Achievements in the Field of Music.
Starting point is 00:03:27 And he's the recipient of the National Medal of Technology. This is a medal granted to you in a ceremony at the White House, which is undercovered by the press, by the way. Because I think somewhere deep down they think it's somehow political. But I was on one of these committees to tell the president who should get such a medal for the National Medal of Science. And we're just sitting there advising the president on what this is. And the president just basically does what we tell him at that level. And so it's basically the country's Nobel Prize, if you will, for the country honoring its own citizens for their contributions in science. And in this case, the National Medal of Technology.
Starting point is 00:04:07 And he was inducted into the National Inventors Hall of Fame. Why wouldn't he be? I'd be disappointed if this weren't here. Holds 20 honorary doctorates and honors from three U.S. presidents. He's written five national best-selling books, including the New York Times bestseller, The Singularity is Near. I think he was going to start a cult back then.
Starting point is 00:04:36 We'll find out. We'll get to the bottom of that one. And also, How to Create a Mind in 2012. And he is director of Engineering at Google, heading up a team developing machine intelligence and natural language understanding. Help me give a very warm 92nd Street welcome to Ray Kurzweil. Oh, very good. So, Ray, all right, here's what I want to know.
Starting point is 00:05:02 Are you some superhero's nemesis that will show up and bring Superman down when he shows up? Well, I mean, Superman... See, he's got to think. He's wondering if that's... See, he's taking that. That's a serious question to him. You're supposed to say, oh, stop joking.
Starting point is 00:05:22 No, you're thinking, okay, go on. I have thought about that, because I wrote a novel with a superheroine, but she doesn't melt steel with her eyes. She melts problems with her intellect. And so I think actually intelligence is the most powerful force in the universe. Ooh, good answer. Even stronger than gravity, say. Okay, all right.
Starting point is 00:05:42 But this is physics versus computer science, so. Well, good. So one of the things that have been on everyone's mind, especially lately, there have been movies on this,
Starting point is 00:05:51 and there's always been some attempt to portray it, but it seems to be more so lately, and that's the buzz about artificial intelligence. There seems to be fear factors
Starting point is 00:06:01 coupled with euphoria about what role that could play in our lives. And so, do you have any insight into why it's become all the buzz? Well, I've been following this for 50 years. In the 60s, some scientists at Carnegie Mellon said that within 10 years, computers will be able to do anything that a man can do. Now, maybe that was a positive, intended to be a positive comment on what women could do, but it did lend embarrassment to the field, and we entered what was called the AI winter,
Starting point is 00:06:33 where people were very pessimistic, and those of us in the AI fields were sort of embarrassed that, oh, this will never work. Now people suddenly are saying, oh, my God, it's going to work. Everything they thought would have happened in 10 years back in the 1960s, we are saying now is going to happen in 10 years. Well, I'm saying actually computers will reach human intelligence by 2029. I've been saying that consistently.
Starting point is 00:06:58 So that's a little more than 10 years, but not that much more. So just a few years ago, the accusation was, well, AI can't even tell the difference between a dog and a cat. Now it can do that in 10,000 other categories, and you can give this Google program a picture, and it'll say, oh, that's a cat and a dog playing with a ball of yarn on a TV set, and it can accurately describe pictures. It can actually create things that are funny. It can paint a picture in the style of Van Gogh. Why does anyone fear this? This sounds quite primitive. To what, compared with
Starting point is 00:07:33 what scares people. But they've been watching too many AI dystopian futurist movies, where it's usually the AI versus the humans for control of the world, or two groups of humans for control of the AI. We don't have one or two AIs in the world. We have one or two billion AIs. You know, each of these things we carry around with us is an AI. We can access all of human knowledge with a few keystrokes. And that, I think, will keep it safe,
Starting point is 00:08:02 because it's very deeply integrated with humanity. But that's not how it's been portrayed in these dystopian movies. Well, of course, as early as, was it 1985, the film Terminator, the net achieves consciousness and then takes on its own identity. So to say there's a billion AIs and we all share it on our pocket, once the cloud was introduced, this smacks of a centralization of all of our knowledge and all of our decision making.
Starting point is 00:08:35 But it's actually not centralized, is it? I mean, we each have our own cloud, we have our own information. So they want us to believe. Well, interestingly, you know, AI. You're telling me we're all walking around with our own cloud over our head. That's what you're telling me. Well, yeah.
Starting point is 00:08:58 I mean, we're already expanded in the cloud. We're going to do that quite literally in the 2030s. We'll have nanorobots that go inside our brain and connect our neocortex to the cloud. So just the way that this can multiply itself a million fold, like, you know, this is actually a billion times more powerful than the computer I used when I was a student at MIT per dollar. But it can multiply itself thousands of millions fold
Starting point is 00:09:22 in the cloud whenever it needs to. So we can't yet do that with our brains. If you remember, two million years ago, we got these big foreheads. I remember, yeah. And we, so we got additional... The frontal lobe became developed, making
Starting point is 00:09:37 human birth catastrophic for the woman. Right, but there was a benefit to it also. You ever see cats being born? They just pop right out. Because cats have these little heads, nothing complicated in the birth canal. But it was worth it. We got these mondo craniums.
Starting point is 00:09:54 But it was worth it because we got this additional neocortex. Says the man, it was worth it, right? Okay. Well, women got the additional neocortex also. Okay. And what we did with that is we put it at the neocortex, which is where we do our thinking,
Starting point is 00:10:14 is organize in a hierarchy. We put that additional neocortex at the top of the hierarchy. And as you go up the hierarchy, we get more intelligent. Things get more abstract. So at the top of the hierarchy, we say, oh, that's funny, that's ironic, she's pretty. The bottom of the hierarchy, I can tell that the edge of this stage is straight, very simple things. But at the top, we can do humor and music. And in fact, that additional neocortex was the enabling factor for us to
Starting point is 00:10:42 invent language and art and science and physics and StarTalk programs and no other species does any of those things. We're going to add to our neocortex again. Two million years ago that was a one-shot deal. You know, no other primate has this big forehead. They have slanted brows. But it was, you know, it didn't continue to expand otherwise it really would have been a problem with birth. But so we're going to... In fact, it's been suggested that that was the limiting factor
Starting point is 00:11:11 to how much more intelligent we would ever get. Because once you start killing 100% of your mothers, that's the end of the species right there. Right? So there's a trade-off between how many mothers die and how many children are born. Until we go to a whole new paradigm, which is basically to connect
Starting point is 00:11:30 wirelessly our knee cortex to the cloud. Or just birth everyone with a C-section. Then they can have huge heads coming out in the future. Yeah, but still, how big could it be? I mean, it would be very hard to carry them around. The heads would just be... I mean, this multiplies itself a million fold,
Starting point is 00:11:48 but if it were physically a million times heavier, we couldn't carry it around. Good point. We will connect wirelessly our neocortex to the cloud. This is with nanobots that enter your neocortex. Right. So we have 300 million modules in our neocortex, each of which can recognize a pattern that are organized in this hierarchy. We create that hierarchy with our own thinking.
Starting point is 00:12:12 But it's 300 million. So is that a big number or a little? Well, it was big enough for us to invent language and physics. But it's also limited when you realize how long it takes to read a book or learn a language. We will be able to expand that. And that expansion will not be a one-shot deal. It will be connected to the cloud. The cloud is pure information technology. One of my themes is that information technology grows exponentially. It roughly doubles in power every year.
Starting point is 00:12:38 That's what the cloud is doing. The cloud is twice as powerful every year. And when we can connect and expand our neocortex in the cloud, it will expand without limit. And so we'll be funnier and we'll be sexier. So, just to clarify what I think you just said, that in 20 years, plus or minus, so the mid-2030s, we will have nanobots that we can feed into our brain
Starting point is 00:13:07 that directly connect to the cloud rather than through anything we carry in our pocket. And in that way, wirelessly, we can basically download entire books, entire languages, and we will then know these things just by the act of downloading them. Well, that's one implication. Into our brains.
Starting point is 00:13:28 But we'll have more neocortex. So we won't be limited to a mere 300 million pattern modules. We'll have billions or 10 billion. But biologically, or just simply because we have these nanobots? We'll have this extension that's non-biological. Non-biological, right. I mean, this would be pretty useless if it didn't have an extension. I mean, when you access all of Google...
Starting point is 00:13:49 Yes, it would just be a gaming device otherwise. You can access all of knowledge and... I got that. So isn't this like the scene in The Matrix where they sit in the chair and they upload... One of my favorite lines of the film is Keanu Reeves. You know, they teach him martial arts. And he says, I know Kung Fu.
Starting point is 00:14:12 And you mean I'm going to know, you know, or Jiu Jitsu, whatever. So in 20 seconds, he's now an expert. Are you telling me that's what's going to happen? The non-biological portion of our thinking will be able to download skills, right? Wow. All right, so this is intellectual psychological dimension that you're describing. But another fear that people have of AI
Starting point is 00:14:34 is that it might take over all of our jobs that previously used our intellect. That kind of happened 200 years ago and 100 years ago when machines took over human physical labor and people thought that would be the end of all employment, but of course that wasn't the case. It was a naive fear. It's happened many times. I mean, if I were a freshman futurist in 1900, I'd say, okay, a third of you work on farms and a third of you work in factories, but I predict in 100
Starting point is 00:15:04 years, by the year 2000, it will be 3% 3% that is what happened today it's 2% 2% and everyone go oh my god so you were way off all right so all right but that the fear factor is what jobs do the rest of that 60% so what so what happened 65% of jobs today in the United States are information jobs. It didn't exist 25 years ago, let alone 100 years ago. So in 20 years, what's the profile?
Starting point is 00:15:34 Of the workforce? We're going to be smarter, as I said, because we're going to enhance our intelligence, as we already have. Even though this isn't connected in my brain, it may as well be. And it does make us smart. Just a quick insert there. Because it's not
Starting point is 00:15:49 physically connected, but it's at your fingertips, isn't that good enough? I would kind of rather carry this around than let someone inject nanobots into my frontal lobe. Okay, well, speak for yourself. No, I'm just saying... I'm just saying, how quickly do you want to access the data? Although I am nervous that you're not going to grab my phone.
Starting point is 00:16:10 I can wait 20 seconds for this. I'm cool with that. No, I mean, your fingers are very slow, right? I mean, it'll be much faster. Okay, so tell me, what is the... And it's not so futuristic. I mean, Parkinson's patients already have actually many computers connected into their brain.
Starting point is 00:16:31 There are places the part of their brain that was destroyed by that disease, that actually communicates wirelessly. They can download new software to the computers connecting their brain from outside the patient. That's today. They're not blood cell size yet.
Starting point is 00:16:45 They're actually the size of a tiny pea. They can be inserted with minimally invasive surgery. Once they're the size of blood cells, you know, we can just swallow them. Swallow the nanobots. Right. But miniaturization is another exponential trend. We're shrinking technology at a rate of 103 volume per decade. So these computers will be the size of blood cells in the 2030s.
Starting point is 00:17:11 Now, isn't there, I've got to get geeky on you now, isn't there a limit if we're communicating via microwaves, basically, which is the communication technology here? A microwave wavelength is sort of a millimeter up to a few centimeters. here. A microwave wavelength is sort of a millimeter up to a few centimeters, and the receiving device has to be at least as large as the wavelength in order to receive it and extract information from it. If you have something the size of a cell, that is much, much smaller than a millimeter. Okay, you're bringing up an engineering issue. They're not all going to communicate outside the body. They're going to be on a local area network sending
Starting point is 00:17:45 information to each other. So now your body has a local area network inside of it. A very local area network. Yeah, exactly. And that already exists. There are computerized technologies being put in the body where there are local area networks
Starting point is 00:18:01 inside the body. So you're basically creating your own neural net, basically, within you. Exactly. So you already thought this through. Okay, forgive me. Thought I could stump him on that one, but apparently not. So tell me again, what is the distribution of jobs in 20 years?
Starting point is 00:18:29 What percent of people are doing what up and down the line? Well, if you were to describe the jobs that exist today, creating websites and mobile apps and chip designs and computers, if you describe that to people a century ago, they wouldn't know what you're talking about. And if you describe that to people a century ago, they wouldn't know what you're talking about. So we're going to have new types of jobs,
Starting point is 00:18:51 creating new types of knowledge that don't exist yet. And that's been the trend. Ray, that's a cop-out. No, no, I'm not going to accept that. You can't tell me that with some confidence that in 20 years, there'll be nanobots running around our frontal lobe, yet you don't know what the job market will be.
Starting point is 00:19:07 If you're predicting the future, don't tell me now, I have no idea what jobs we're going to have, but you'll have nanobots in your brain? No! Put something on the table. So that in 20 years, we'll put your ass back on the stage and find out
Starting point is 00:19:23 whether it happened. Excuse my language there. Radio podcast with comedians. It won't just be one or two of us that can do that. We'll all be able to do that. We'll be funnier. We'll be creating more profound music, literature, science, technology.
Starting point is 00:19:48 I mean, look at how many fields there are of science and technology, there's thousands of them. They didn't even exist 20 years ago, let alone 100. 100 years ago there was physics and chemistry, and that's why the Nobel Prizes. Physics, chemistry, biology, I mean, most of the fields didn't exist then. And now we have thousands of these fields.
Starting point is 00:20:07 It's going to, we're going to continue this exponential explosion of knowledge. And we're going to continue going up Maslow's hierarchy, where we don't have to do, you know, people are very eager to retire because they basically don't like their work. The goal of life is, I think, actually to love what you do. I like to say I retired when I was five because I decided I would do what I wanted.
Starting point is 00:20:33 I think that is really the goal, to be able to have a passion for what you do. How old were you when you wrote your first computer program? Well, 12, but there were only 12 computers in all of New York City. At the time. So why did they... What crazy, stupid person allowed a 12-year-old to touch one of the 12 computers of New York City?
Starting point is 00:20:54 So can we distinguish, just to get our lexicon on the same page, when I think of biotech, I don't think of nanobots. I think of just the future of possibly manipulating the genome, this sort of thing. So where are you with regard to advances we might make in our biological form
Starting point is 00:21:16 versus the connection between technology and our biological form? Right. So there are three overlapping revolutions. They all have to do with information. Biotechnology, nanotechnology and artificial intelligence. And they're
Starting point is 00:21:30 in that order. So biotechnology is here now. And it basically consists of the observation that we are software. Our biology is software. It's made up of genes. There's actual sequences of data. They evolved a long time ago and conditions are very different.
Starting point is 00:21:46 For example, one of our little 23,000 little software programs is called the fat insulin receptor gene. It says basically hold on to every calorie because the next hunting season may not work out so well. And that was a good idea a thousand years ago. You worked all day to get a few calories and there were no refrigerators so you stored them in the fat cells of your body.
Starting point is 00:22:06 I would like to tell my fat insulin receptor gene, you don't need to do that anymore. I'm confident the next hunting season will be good. Like three hours from now when you're served your next meal. At the supermarket.
Starting point is 00:22:21 Yeah. Supermarkets, like, food is spilling off the shelves of supermarkets. So that was done. We have means now of turning off genes. So they turned off this gene in animals, and these animals ate ravenously and remained slim, and they
Starting point is 00:22:37 lived 20% longer, and they got the benefits of caloric restriction while doing the opposite. And the Johnson Diabetes Center is working with a drug company to bring that to the human market that's just 23 this one of the 23,000 genes you'd like to tinker with biology is very limited in in capability it can only last so long and wears out and so ultimately we can go beyond the limitations of
Starting point is 00:23:01 biology so this is overlapping revolutions. The ultimate health revolution with nanobots is basically a little programmable nanobot that's just like the T cells in your body. It can go after pathogens, but it's not limited by the limitations of our immune system. Our immune system evolves. So we just do better than what you're born with, basically.
Starting point is 00:23:26 Right. For example, our immune system doesn't go after cancer. It says, oh, that's me, and it doesn't consider it an enemy. It doesn't work on retrovirus like HIV. Stupid immune system. It is stupid. I mean, life expectancy was 19,000 years ago. It was not in the interest of biology for people to live very long
Starting point is 00:23:42 because it was very limited food. And now there's some value for, you know, older folks like you and me to share our experience and accumulated knowledge. So we'd like to live longer and go beyond these natural limits. So just perfecting biology is not ultimately as good as going beyond the limitations.
Starting point is 00:24:04 And the pure technology will enable that and empower that. Right, so that's another application of these nanobots. You wrote a book in 1999 called The Age of Spiritual Machines. Everybody's got their own private definition of how they use the word spiritual. And it's the latest thing when you want to say you're religious, you say, but I'm spiritual. So how are you using that word in the title of
Starting point is 00:24:25 that book? Well, what is the ultimate spiritual value? It's consciousness. We feel that a conscious entity is sacred, like a person or like an animal that has feelings. But not everybody actually agrees on which animals or if animals are conscious. Anyone who owns a dog or a cat is certain they have conscience. Well, that underlies the debate about animal rights. I mean, I feel my cat is conscious. Not everybody agrees with that. Those people probably haven't met my cat.
Starting point is 00:24:58 But... Did you create this cat? Well, my cat is robotic, actually, as it turns out. But we will have that debate about machines. Now, we don't worry today about causing pain and suffering to our computer software. We're more concerned about the pain and suffering it causes us. But that is actually, when I talk
Starting point is 00:25:24 about computers reaching human levels of intelligence, I'm not talking about logical intelligence. If you say, ah, well, emotions, spirituality, consciousness, those are all sideshows. The essence of intelligence is, you know, ability to think logically. Well, then computers are already smarter than we are. It is being funny and expressing a loving sentiment where humans have an edge today. That is the cutting edge of human intelligence. But that's where I think computers will match human intelligence by 2020. So let me ask, just to get a little philosophical on you. As a scientist, and I grew up basically in the geekosphere, and I'm curious, when we think of who is smart in the class, it's who knows the most, who can solve a problem the most. It's not the
Starting point is 00:26:14 person who's most emotional. Generally, we don't use the word smart for that person, yet you are grouping that feature of what it is to be human as something that computers have yet, a place where computers have yet to tread. And when they do, they'll then be truly smarter than us. But if your emotions, for example, interfere with your ability to make the correct decision given the outcome you seek, how can we possibly call that intelligence?
Starting point is 00:26:42 Well, I mean, you go around with a comedian for some of your presentations recognizing that humor is in fact a high form of intelligence it takes a lot of intelligence to think of what he's referring to is that the star talk radio show my co-host is always a professional stand-up comedian bringing a level of levity to the conversation and insight i mean yeah humor humor is a high form of intelligence, and creating poetic language is a form of intelligence. Expressing a loving sentiment, music, either recreating it or creating in the first place,
Starting point is 00:27:17 these are really the highest forms of intelligence. Computers are beginning to encroach on that. So what you're saying, not to put words in your mouth, but that's exactly what I'm going to do. What you're saying is right now, the computer can wipe our floor in a game of chess that we invented. The computer can beat us at Jeopardy, a game that we invented, and it's based basically on pop culture. So the computer can beat us at all of these things. It still can't beat us in our capacity to write a brilliant novel
Starting point is 00:27:52 or to compose a beautiful poem or to paint a transcendent work of art. Exactly, although Jeopardy is a step in that direction. I got you. So what I'm asking you is, are you saying the day will come where the computer will write the Nobel Prize winning novel and the poem that generations will study thereafter and supplant even that aspect of what it is to be human? Right. But I put it differently in that we're going to combine with that intelligence. We're going to become a merger of biological and non-biological intelligence.
Starting point is 00:28:25 We are already... So there'll still be humans who do this. It's enhanced. We create these tools to extend our reach. This allows us to remember all of human knowledge. We can build great structures like this building here, which we couldn't do with our bare muscles. So we extend our reach,
Starting point is 00:28:41 and we're going to do that intellectually. And we're doing that already, but it's going to become more profound. So you're ready to erase the difference between a machine that has this power and a human that has been enhanced by that which ever gave the machine power in the first place. But I mean, you know, what is a human? But it's a collection of physical stuff which follows the laws of physics. It's not a mystical property.
Starting point is 00:29:08 We can study a neuron, and it is a machine. So we are perhaps the most complex machine that we know about in the universe. So then the individuality will go away because we will all have exactly the same access. On the contrary. It will become more different. We're actually more the same access. On the contrary, we'll become more different. We're actually more the same now. We all have the same architecture, 300 million neocortical modules. Yeah, but we both eat the same set of nanobots,
Starting point is 00:29:34 and it goes to our frontal lobe. So aren't we still the same now with nanobots running around our head? No, we can become more different, because right now we have the same architecture brain. We may fill it with different thoughts and uh marvin minsky who died recently was my mentor and he wrote a book called the society of mind basically describing our neocortex as a society of different factions that fight each other and uh so some of those societies are more effective because they're harmonious and working together and some of our societies of mind are at war with each other and therefore we're
Starting point is 00:30:09 ineffective but we have basically the same architecture so what you're saying is with this new architecture there are more places to go emotionally and intellectually exact so that if I have leanings whatever is causing that towards poetry rather than physics I can then be a great poet enhanced by all of the nanobots that allow it you can profoundly study and master poetry or music or uh in a in a deeper way than we can today because we'll have more brain power to apply to it. We'll become more different. I got a question for you. All right.
Starting point is 00:30:48 As an astrophysicist, we think about aliens a lot. I'm not authorized to divulge any more about that than that. And what I think about often is how much on Earth in human civilization we invest in ways that titillate or stimulate or serve our five senses. So there's a sense of taste.
Starting point is 00:31:15 So there's fine dining and wine and restaurants. And there's a sense of touch. So we pay good money for a massage. There's a sense of sight. So we like looking at art. And there's a sense of sight. So we like looking at art. And there's a sense of hearing. So we make music. An alien might have 12 senses instead of five.
Starting point is 00:31:33 And so you visit their society. They might have whole tracks of their economy in the service of titillating their other senses that are completely oblivious to us. Can you imagine a future where we actually give ourselves more senses that we might get addicted to them being served? So you ask what kind of work we'll do.
Starting point is 00:31:58 We'll be creating art and experiences and virtual environments for these additional senses or enhanced senses. In a sense, we're already doing that, the kind of virtual reality, you know, environments and experiences that are now emerging. Would it be even hard to describe a couple of decades ago? So, yes, I think we can...
Starting point is 00:32:21 All this sensory information, you know, as a physicist, a lot of it we don't capture. Most of it, it just goes right by. Right. So we could capture that and create enhancements, you know, like culinary and musical and artistic experiences with these enhanced senses. So that's another way in which we can create a kind of work that we can't even describe today. There's another topic that makes the news every now and then, and it's the possibility that we might be on the brink of a medical advance
Starting point is 00:33:00 that would have humans live forever. So is that a good thing? Yes. You're going to need another planet. Because if people don't die, I did the math on this, okay? At the rate that we are now growing our population, in the same number of years in our future, as has elapsed since Columbus, we will have a population so large on Earth
Starting point is 00:33:28 that everyone will have to stand up straight in order to fit in the available landmass. You need another planet. That's with people dying, by the way. That's with regular people dying at age 80, 85. Now you want people to live forever? Well, I dispute that math, but before we get to that, let's talk about how we will actually
Starting point is 00:33:50 achieve... It's a 2% growth with a doubling time of 37 years. I mean, right now, if you take a train across America or any part of the world, 99% of the land is not used. And you could actually build a luxury housing for everybody in the world and fit them in a small part of Texas. So we actually have plenty of land mass. And we have plenty of resources. For example, energy. Oh, we're running peak oil, running out of energy.
Starting point is 00:34:24 We have 10,000... Just to be clear, peak oil is almost jargon, energy. Oh, we're running peak oil, running out of energy. We have 10,000... Just to be clear, peak oil is almost jargon, actually. And it refers to the point in time, whether or not, I don't think we've hit it yet, where thereafter, we will only be drawing less oil out of the ground than what had been drawn previously, which means the oil economy must shrink thereafter.
Starting point is 00:34:44 And so it's been all the talk in economic circles. Go on. Yeah, I mean, even with an oil, shale oil, we have like 5,000 times more oil than we need to meet all of our energy needs. But we have 10,000 times more energy than we need coming from the sun for free. And solar energy is growing exponentially.
Starting point is 00:35:03 That's one of my themes. It's doubling every two years. Our technology that enables us to harness solar energy is doubling every two years. And there's only six doublings now from 100%. So within 12 years we could meet all of our energy needs ultimately at very low cost. And at that point we'll be using one part
Starting point is 00:35:22 in 10,000 of the sunlight. So we have 10,000 times more energy than we need inside the earth with geothermal, there's tides and wind. I mean, we're awash in energy. We're also awash in water. It's just most of it can't be used because it's salinated or polluted.
Starting point is 00:35:41 But if we have clean energy, we know how to clean up water. That's actually a joke. We're awash in water. Yeah, just kidding if you caught that. All right, so you're not worried that Earth can support a quadrillion people. You're not worried about this.
Starting point is 00:35:54 You're not worried. Not about that issue, no. So what are you worried about? So if I were to ask, what is Ray's worry list? Give me your, like, top three or four things. Well, I mean, there's been a lot of concern now about the downsides of these technologies. What, such as?
Starting point is 00:36:17 Such as AI run amok, a la the kinds of futurist dystopian movies that we've seen, like Terminator. So, Elon Musk and Stephen Hawking have been sounding the alarm that oh my god, you know, AI is really going to work and maybe it's going to be dangerous. So I mean I wrote about this going back to the age of spiritual machines in 1999 and that led Bill Joy
Starting point is 00:36:41 who was then the chief technology officer of Digital Equipment Corporation. At that time he was a leading technologist and he wrote a cover story in Wired Magazine, Why the Future Doesn't Need Us, about the grave dangers of GNR, genetics, nanotechnology, robotics, which was artificial intelligence. And basically described these downsides
Starting point is 00:37:03 which I described in my book. So technology has been a double-edged sword ever since. The sword. Yeah. And fire, I mean, which kept us warm and cooked our food but burned down our houses. And these new technologies are very powerful and they can be used for good or ill.
Starting point is 00:37:21 So I do take comfort from the experience we've had with one of these technologies, which is already working, which is biotechnology. So the same technology which we can use to reprogram ourselves away from disease and away from cancer could also be used by a bioterrorist to reprogram a benign virus like a cold or flu virus to be deadly, communicable, and stealthy. Basically weaponize a virus, essentially. So that was recognized more than 25 years ago and they held a conference called the Asilomar Conference and came up with a set of guidelines to keep biotechnology safe. It's called the Asilomar Guidelines and they've been
Starting point is 00:37:58 reinvented every few years as the technology gets more sophisticated. This is our attempt to have a morality to keep track with the... Ethical standards, and this has actually worked. We're now getting benefits. You can now, for example, fix a broken heart. Not yet from romance. That'll take some more advances in virtual reality, but from
Starting point is 00:38:18 a heart attack... I won't even take that another step. We'll let that one go. Half of all heart attack survivors have a damaged heart. My father had that in the 60s. We didn't know anything about stem cells then. But I've talked to people who could hardly walk after a heart attack and now they've been rejuvenated
Starting point is 00:38:35 by reprogramming adult stem cells. So we're getting, I could go on, we could talk for hours about the benefits. And there have been no, the number of negative incidents have been zero. Now, that doesn't mean we can cross it off our worry list. Okay, we took care of that one. Because the technology gets more sophisticated and there are new dangers emerging all the time. But it's a good model for how we can keep these technologies safe.
Starting point is 00:39:02 That's number one, is you have a second concern. can keep these technologies safe. That's number one, is you have a second concern. Well, that's... There are existential risks, like biotech run them up. There are subtle risks, like losing privacy, for example, is very much on people's minds.
Starting point is 00:39:19 And as a computer guy, fundamentally, in spite of that you have these inventions and patents, you're a computer guy in your soul of souls. Does the lack of privacy concern you? I'm actually not... By the way, and I say that, the obvious answer should be yes. However, anyone younger than 25 puts everything they ever could possibly know about them on their Facebook page. So they have no commensurate concept of privacy relative to the Cold War generation
Starting point is 00:39:53 where there were spies and you had to keep secrets. I'm actually less concerned about that. I think we're doing a pretty good job on privacy. I mean, how often do you hear about major breaches with Apple's email or Google's email? I mean, these companies know how to keep this information secure. And actually. So tell me about the Apple versus FBI.
Starting point is 00:40:19 There's many layers to that dispute. Now, the FBI could crack that phone easily. I mean, it's very simple to do. many layers to that dispute. Now, the FBI could crack that phone easily. I mean, it's very simple to do. There's some code in there which detects... Wait, wait. Ray Kurzweil saying something is simple is not the same thing as the FBI saying something is simple. Well, they
Starting point is 00:40:37 can absolutely crack that phone. Wait, wait. If someone was good enough to crack the phone, they wouldn't be working for the FBI. They'd be working for Apple, getting five times the salary, wouldn't they? Well, there's software in the phone that detects if you're trying different combinations of passwords, of past numbers. And if it detects that, it then stops you and actually erases the information. It self-destructs. Right.
Starting point is 00:41:02 Without the Mission Impossible smoke coming out of it. So you could take the software, which is an object code, and disassemble it, and a competent programmer could find where that code is and bypass it. And the FBI can do that. So they would bypass the code, and therefore they'd be able to run through the 10,000 possible codes. So why is it that they're pressing this case? Both Apple and the government are really concerned about the precedent.
Starting point is 00:41:26 The FBI wants a precedent set so they can come with other requests in the future, and Apple doesn't want the precedent set. So this one phone is really, it's a federal case, more because it's a precedent than because they need phone numbers. Because of the underlying issue. Now, it's not an easy issue. I mean, suppose there was a phone that had information that could lead you to stop a terrorist attack using WMD.
Starting point is 00:41:58 I mean, most people would support, oh, we've got to get that information and stop this kind of attack. I mean, there could be attacks that make San Bernardino and Paris seem trivial. I got to interject a story. Now, 20 years ago, we were exploring what technologies we might use for the new planetarium that we were building, what became the Rose Center for Earth and Space. And one of our trips was to East Germany. Now, this is seven years after the wall came down,
Starting point is 00:42:31 but I still call it East Germany because it was very different from West Germany. People's clothing was not very colorful. People hardly smiled. The culture, the mood was completely different from anything we had grown up and experienced in the West. And I finally had a long conversation with someone that I just never had a conversation, you know, I grew up in the West,
Starting point is 00:42:50 in the Bronx, right? And I had a conversation and I said, what was going on behind these walls? Oh, our government told us that all of these protections were necessary to keep us safe. We need the wall. We have to prevent you from watching these TV shows. We have to prevent you from traveling to these places or reading these newspapers. And so when I heard that, I said, wow, so you can basically subjugate an entire population
Starting point is 00:43:21 on the grounds that you are doing something in their best interest. So for you to say that surely you would want to break the code of privacy if it could prevent a weapon of mass destruction, that makes a good headline, but the total picture that that paints scares me. Well, I think... Thank you. Well, I think.
Starting point is 00:43:50 Okay, that's the other 40% on that side, right? Yeah. I think we have, you know, a basic conflict between privacy and security. But I think privacy is going to win. There are now encryption codes that are unbreakable. And, you know, regardless of what companies like Apple do, people are going to use a layer of encryption that cannot be broken and that already exists and it's already being used. So ultimately privacy is actually going to win,
Starting point is 00:44:18 which is good from that perspective. We'll have to find other ways to stop criminals and terrorists. And I'll, you know, I don't work for the intelligence agencies, so I'll leave it to them to. So is Ed Snowden a hero of yours or a traitor or a treasonist? What is he to you? We learned a lot that I think the American people needed to know from his revelations.
Starting point is 00:44:46 So in that regard it was a good thing. The authorities claim that he compromised information which put people's lives at risk. I have no way of evaluating that. But we do know a lot of things that the government was doing that we didn't know before. And I think that's a positive thing It's pretty amazing that this low-level contractor had access to so much information. He was really smart
Starting point is 00:45:13 In fact we interviewed him for StarTalk. Yeah, yeah He sent to a bot a motorized bot not a nano bot He didn't get in my head the end came in and I said, how do I know you're really controlling it? So he wanted to see me turn left and then he like turned left and then turned right. But he wouldn't tell me where he was hiding. But we have the whole, it's all on StarTalk. It's been posted.
Starting point is 00:45:33 So these are other challenges. I worry that if nanobots are coursing through my brain that someone one day might be able to control that. I kind of would rather stay biological as I... Well, your thoughts already in your emails and your texts, and you worry about that being... Yeah, because I did that on purpose. I'm cool with stuff I do on purpose.
Starting point is 00:45:54 It's when someone has access because my frontal lobe nanobots are connected somewhere in some cloud. I don't know who's coming back into my head. We do express ourselves pretty intimately in all of our communications, and all of that's electronic. And I travel around the world. I don't talk to very many people at all who say,
Starting point is 00:46:16 oh, my life was ruined because my privacy was infringed on. So I think we're doing a pretty good job on privacy. And it's just a technical reality that the technology of privacy, which is encryption, is outpacing decryption. So if you're on the side of privacy, I think... I like that phrase. Encryption is outpacing decryption. That's really good. That gives me hope. More hope than I had when you first sat down well actually actually has to do with physics because uh it was you know the big worry was quantum computers would break any possible encryption code and so that would be the end of privacy i i was always dubious that the quantum
Starting point is 00:46:57 computers would ever work and they they don't work and i don't think they will so privacy i think is alive and well uh so let me let me just ask, just because I love pop culture and I love going to movies, is there a film that, in your judgment, most accurately portrays the future of AI? Well, I thought a pretty good movie was Her because there wasn't one AI out there. Like, everybody had their operating system.
Starting point is 00:47:24 So Theodore had Samantha, and his human love interest also had her operating system that she fell in love with. And they were your administrative assistants and, but also it was Theodore's therapist and Theodore's lover and it expanded Theodore's capabilities and experiences. So I think something like that will take place. I thought it was didn't make sense that Samantha
Starting point is 00:47:54 didn't have a body. It'll be easier to provide a human level body in virtual and augmented reality. That would open up a whole other industry. Well that's always the case with all of these communication technologies.
Starting point is 00:48:11 You know, the first book printed was a Bible, but then came a whole century of more prurient titles. Okay, so, ladies and gentlemen, join me in thanking Ray Kurzweil.
