The Godfather of AI: Jeffrey Hinton on Career Prospects and AI Risks

They call you the godfather of AI. So what would you be saying to people about their career prospects in a world of

super intelligence? Train to be a plumber. Really? Yeah. Okay. I'm going to become a plumber. Jeffrey Hinton is

the Nobel Prize winning pioneer whose groundbreaking work has shaped AI and the future of humanity. Why do they call

it the godfather of AI? because there weren't many people who believed that we could model AI on the brain so that it

learned to do complicated things like recognize objects and images or even do reasoning. And I pushed that approach

for 50 years and then Google acquired that technology and I worked there for 10 years on something that's now used

all the time in AI. And then you left. Yeah. Why? So that I could talk freely at a conference. What did you want to

talk about freely? How dangerous AI could be. I realized that these things will one

day get smarter than us. And we've never had to deal with that. And if you want to know what life's like when you're not

the apex intelligence, ask a chicken. So there's risks that come from people misusing AI. And then there's risks from

AI getting super smart and deciding it doesn't need us. Is that a real risk? Yes, it is. But they're not going to

stop it cuz it's too good for too many things. What about regulations? They have some, but they're not designed to

deal with most of the threats. Like the European regulations have a clause that say none of these apply to military uses

of AI. Really? Yeah. It's crazy. One of your students left OpenAI. Yeah. He was probably the most important person

behind the development of the early versions of church GPT and I think he left because he had safety concerns. We

should recognize that this stuff is an existential threat and we have to face the possibility that unless we do

something soon we're near the end. So let's do the risks. What do we end up doing in such a world?

This has always blown my mind a little bit. 53% of you that listen to the show regularly haven't yet subscribed to the

show. So, could I ask you for a favor before we start? If you like the show and you like what we do here and you

want to support us, the free simple way that you can do just that is by hitting the subscribe button. And my commitment

to you is if you do that, then I'll do everything in my power, me and my team, to make sure that this show is better

for you every single week. We'll listen to your feedback. We'll find the guests that you want me to speak to and we'll

continue to do what we do. Thank you so much. Jeffrey Hinsson, they call you the

godfather of AI. Uh yes they do. Why do they call you that? There weren't that many people who

believed that we could make neural networks work, artificial neural networks. So for a long time in AI from

the 1950s onwards, there were kind of two ideas about how to do AI. One idea was that sort of core of human

intelligence was reasoning. And to do reasoning, you needed to use some form of logic. And so AI had to be based

around logic. And in your head, you must have something like symbolic expressions that you manipulated with rules. And

that's how intelligence worked. And things like learning or reasoning by analogy, that all come later once we've

figured out how basic reasoning works. There was a different approach, which is to say, let's model AI on the brain

because obviously the brain makes us intelligent. So simulate a network of brain cells on a computer and try and

figure out how you would learn strengths of connections between brain cells so that it learned to do complicated things

like recognize objects in images or recognize speech or even do reasoning. I pushed that approach for like 50 years

because so few people believed in it. There weren't many good universities that had groups that did that. So if you

did that the best young students who believed in that came and worked with you. So I was very fortunate in getting

a whole lot of really good students some of which have gone on to create and play an instrumental role in creating

platforms like open AI. Yes. So I sus a nice example a whole bunch of them. Why did you believe that modeling it off

the brain was a more effective approach? It wasn't just me believed it early on. Fonoyman believed it and Cheuring

believed it and if either of those had lived I think AI would have had a very different history but they both died

young. You think AI would have been here sooner? I think neural net the neural net approach would have been accepted

much sooner if either of them had lived in this season of your life. What mission are you on? My main mission now

is to warn people how dangerous AI could be. Did you know that when you became the godfather of AI? No, not really. I

was quite slow to understand some of the risks. Some of the risks were always very obvious, like people would use AI

to make autonomous lethal weapons. That is things that go around deciding by themselves who to kill. Other risks,

like the idea that they would one day get smarter than us and maybe would become irrelevant, I was slow to

recognize that. Other people recognized it 20 years ago. I only recognized it a few years ago that that was a real risk

that was come might be coming quite soon. How could you not have foreseen that if if with everything you know here

about cracking the ability for these computers to learn similar to how humans learn and just you know introducing any

rate of improvement? It's a very good question. How could you not have seen that? But remember neural networks 20 30

years ago were very primitive in what they could do. They were nowhere near as good as humans, but things like vision

and language and speech recognition. The idea that you have to now worry about it getting smarter than people, that seems

silly then. When did that change? It changed for the general population when chat GPT came out. It changed for me

when I realized that the kinds of digital intelligences we're making have something that makes them far superior

to the kind of biological intelligence we have. If I want to share information with you, so I go off and I learn

something and I'd like to tell you what I learned. So I produce some sentences. This is a rather simplistic model, but

roughly right. Your brain is trying to figure out how can I change the strength of connections between neurons. So I

might have put that word next. And so you'll do a lot of learning when a very surprising word comes and not much

learning when if it's when it's very obvious word. If I say fish and chips, you don't do much learning when I say

chips. But if I say fish and cucumber, you do a lot more learning. You wonder why did I say cucumber? So that's

roughly what's going on in your brain. I'm predicting what's coming next. That's how we think it's working. Nobody

really knows for sure how the brain works. And nobody knows how it gets the information about whether you should

increase the strength of a connection or decrease the strength of a connection. That's the crucial thing. But what we do

know now from AI is that if you could get information about whether to increase or decrease

the connection strength so as to do better at whatever task you're trying to do, then we could learn incredible

things because that's what we're doing now with artificial neuronets. It's just we don't know for real brains

how they get that signal about whether to increase or decrease. As we sit here today, what are the big

concerns you have around safety of AI? if we were to to list the the top couple that are really front of mind and that

we should be thinking about. Um, can I have more than a couple? Go ahead. I'll write them all down and we'll go through

them. Okay. First of all, I want to make a distinction between two completely different kinds of risk.

There's risks that come from people misusing AI. Yeah. And that's most of the risks and all of the short-term

risks. And then there's risks that come from AI getting super smart and deciding it doesn't need us. Is that a real risk?

And I talk mainly about that second risk because lots of people say, "Is that a real risk?" And yes, it is. Now, we

don't know how much of a risk it is. We've never been in that situation before. We've never had to deal with

things smarter than us. So really, the thing about that existential threat is that we have no idea how to deal with

it. We have no idea what it's going to look like. And anybody who tells you they know just what's going to happen

and how to deal with it, they're talking nonsense. So, we don't know how to estimate the probabil probabilities

it'll replace us. Um, some people say it's like less than 1%. My friend Yan Lar who was a postto with me thinks no

no no, we're always going to be we build these things. We're always going to be in control. We'll build them to be

obedient. And other people like Yudkowski say, "No, no, no. These things are going to

wipe us out for sure. If anybody builds it, it's going to wipe us all out." And he's confident of that. I think both of

those positions are extreme. It's very hard to estimate the probabilities in between. If you had to bet on who was

right out of your two friends, I simply don't know. So, if I had to bet, I'd say the probabilities in

between, and I don't know where to estimate it in between. I often say 10 to 20% chance they'll wipe us out, but

that's just gut based on the idea that we're we're still making them and we're pretty ingenious. And the hope is that

if enough smart people do enough research with enough resources, we'll figure out a way to build them so

they'll never want to harm us. Sometimes I think if we we talk about that second um path, sometimes I think about nuclear

bombs and the the invention of the atomic bomb and how it compares like how is this different because the atomic

bomb came along and I imagine a lot of people at that time thought our days are numbered. Yes, I was there. We did.

Yeah. But but but what's what h we're still here. We're still here. Yes. So the atomic bomb was really only good for

one thing and it was very obvious how it worked. Even if you hadn't had the pictures of Hiroshima and Nagasaki, it

was obvious that it was a very big bomb that was very dangerous. With AI, it's good for many, many things. It's

going to be magnificent in healthcare and education and more or less any industry that needs to use its data is

going to be able to use it better with AI. So, we're not going to stop the development.

You know, people say, "Well, why don't we just stop it now?" We're not going to stop it because it's too good for too

many things. Also, we're not going to stop it because it's good for battle robots, and none of the countries that

sell weapons are going to want to stop it. Like the European regulations, they have some regulations about AI, and it's

good they have some regulations, but they're not designed to deal with most of the threats. And in particular, the

European regulations have a a clause in them that say none of these regulations apply to military uses of AI.

So governments are willing to regulate regulate companies and people, but they're not willing to regulate

themselves. It seems pretty crazy to me that they I go back and forward, but if Europe has a

regulation, but the rest of the world doesn't competitive disadvantage. Yeah, we're

seeing this already. I don't think people realize that when OpenAI release a new model or a new piece of software

in America, they can't release it to Europe yet because of regulations here. So Sam Alman tweeted saying, "Our new AI

agent thing is available to everybody, but it can't come to Europe yet because there's regulations."

Yes. What does that gives us a productive disadvantage? Productivity disadvantage. What we need is I mean at

this point in history when we're about to produce things more intelligent than ourselves, what we really need is a kind

of world government that works run by intelligent, thoughtful people. And that's not what we got.

So free-for-all. Well, that what we've got is sort of we've got capitalism which is done very

nicely by us. is produce lots of goods goods and services for us. But these big companies, they're legally required to

try and maximize profits and that's not what you want from the people developing this stuff.

So let's do the risks then. You talked about there's human risks and then there's So I've distinguished these two

kinds of risk. Let's talk about all the risks from bad human actors using AI. There's cyber attacks.

So between 2023 and 2024, they increased by about a factor of 12,200%.

And that's probably because these large language models make it much easier to do fishing attacks. And a fishing attack

for anyone that doesn't know is it's they send you something saying, uh, hi, I'm your friend John and I'm stuck in El

Salvador. Could you just wire this money? That's one kind of attack. But the fishing attacks are really trying to

get your loon credentials. And now with AI, they can clone my voice, my image. They can do all that. I'm struggling at

the moment because there's a bunch of AI scams on X and also Meta. And there's one in particular on Meta, so Instagram,

Facebook at the moment, which is a paid advert where they've taken my voice from the podcast. They've taken the my

mannerisms and they've made a new video of me encouraging people to go and take part in this crypto Ponzi scam or

whatever. And we've been, you know, we spent weeks and weeks and weeks and weeks and end emailing Meta telling,

"Please take this down." They take it down, another one pops up. They take that one down, another one pops up. So,

it's like whack-a-ole. And then it's very annoying. The the heartbreaking part is you get the messages from people

that have fallen for the scam and they've lost £500 or $500 and they cross with you cuz you recommended it and I'm

I'm like I'm sad for them. It's very annoying. Yeah. I have a a smaller version of that which is PE some people

now publish papers with me as one of the authors. Mhm. And it looks like it's in order that they can get lots of

citations to themselves. Ah, so cyber attacks a very real threat. There's been an explosion of those. And these already

obviously AI is very patient. So they can go through 100 million lines of code looking for known ways of attacking

them. That's easy to do. But they're going to get more creative and they may some people believe and I some people

who know a lot believe that maybe by 2030 they'll be creating new kinds of cyber attacks which no person ever

thought of. So that's very worrisome because they can think for themselves and discover they can think for

themselves. They can draw new conclusions from much more data than a person ever saw. Is there anything

you're doing to protect yourself from cyber attacks at all? Yes. It's one of the few places where I changed what I do

radically because I'm scared of cyber attacks. Canadian banks are extremely safe. In 2008, no Canadian banks came

anywhere near going bust. So, they're very safe banks because they're well regulated, fairly well regulated.

Nevertheless, I think a cyber attack might be able to bring down a bank. Now, if you have all my savings are in shares

in banks held by banks, so if the bank gets attacked and it holds your shares, they're still your shares. And so, I

think you'd be okay unless the attacker sells the shares because the bank can sell the shares. If the attacker sells

your shares, I think you're screwed. I don't know. I mean, maybe the bank would have to try and reimburse you, but the

bank's bust by now, right? So, So I'm worried about a Canadian bank being taken down by a cyber attack and

the attacker selling selling shares that it holds. So I spread my money and my children's money between three banks in

the belief that if a cyber attack takes down one Canadian bank, the other Canadian banks will very quickly get

very careful. And do you have a phone that's not connected to the internet? Do you have any like, you know, I'm

thinking about storing data and stuff like that. Do you think it's wise to consider having cold storage? I have a

little disc drive and I back up my laptop on this hard drive. So I actually have everything on my laptop on a hard

drive. At least you know if the whole internet went down I had the sense I still got it on my laptop and I still

got my information. Okay. Then the next thing is using AI to create nasty viruses.

Okay. And the problem with that is that just requires one crazy guy with the grudge. One guy who knows a little bit

of molecular biology, knows a lot about AI, and just wants to destroy the world. You can now create

new viruses relatively cheaply using AI. And you don't have to be a very skilled molecular biologist to do it. And that's

very scary. So you could have a small cult, for example. a small cult might be able to raise a

few million dollars. For a few million dollars, they might be able to design a whole bunch of viruses. Well, I'm

thinking about some of our foreign adversaries doing government funded programs. I mean, there was lots of talk

around COVID and Woo the Wuhan laboratory and what they were doing and gain a function research, but I'm

wondering if in, you know, a China or a Russia or an Iran or something, the government could fund a program for a

small group of scientists to make a virus that they could, you know, I think they could. Yes. Now, they'd be worried

about retaliation. They'd be worried about other governments doing the same to them. Hopefully, that would help keep

it under control. They might also be worried about the virus spreading to their country. Okay? Then there's um

corrupting elections. So, if you wanted to use AI to corrupt elections,

a very effective thing is to be able to do targeted political advertisements where you know a lot about the person.

So anybody who wanted to use AI for corrupting elections would try and get as much data as they could about

everybody in the electorate. With that in mind, it's a bit worrying what Musk is doing at present in the States, going

in and insisting on getting access to all these things that were very carefully siloed. The claim is it's to

make things more efficient, but it's exactly what you would want if you intended to corrupt the next election.

How do you mean? Because you get all this data on the people. You get all this data on people. You know how much

they make where they you know everything about them. Once you know that, it's very easy to manipulate them because you

can make an AI that you can send messages um that they'll find very convincing telling them not to vote, for

example. So, I have no no reason other than common sense to think this, but I

wouldn't be surprised if part of the motivation of getting all this data from American government sources is to

corrupt elections. Another part might be that it's very nice training data for a big model, but he would have to be

taking that data from the government and feeding it into his Yes. And what they've done is turned off lots of the

security controls, got rid of the some of the organization to protect against that. Um, so that's corrupting

elections. Okay. Then there's creating these two echo chambers by organizations like YouTube

and Facebook showing people things that will make them indignant. People love to be indignant. Indignant as in angry or

what does indignant mean? Feeling I'm sort of angry but feeling righteous. Okay. So, for example, if you were to

show me something that said Trump did this crazy thing, here's a video of Trump doing this completely crazy thing.

I would immediately click on it. Okay. So, putting us in echo chambers and dividing us. Yes. And that's um the

policy that YouTube and Facebook and others use for deciding what to show you next is causing that. If they had a

policy of showing you balanced things, they wouldn't get so many clicks and they wouldn't be able to sell so many

advertisements. And so it's basically the profit motive is saying show them whatever will make

them click. And what'll make them click is things that are more and more extreme. And that confirmed my existing

bias. That confirm my existing bias. So you're getting your biases confirmed all the time further and further and further

and further, which means you're you're driving away, which is now there's in the states there's two communities that

don't hardly talk to each other. I'm not sure people realize that this is actually happening every time they open

an app. But if you go on a Tik Tok or a YouTube or one of these big social networks, the algorithm, as you you

said, is designed to show you more of the things that you had interest in last time. So, if you just play that out over

10 years, it's going to drive you further and further and further into whatever ideology or belief you have and

further away from nuance and common sense and um parity, which is a pretty remarkable thing. I I like people don't

know it's happening. They just open their phones and experience something and think this is the news or the

experience everyone else is having. Right. So, basically, if you have a newspaper and everybody gets the same

newspaper, Yeah. you get to see all sorts of things you weren't looking for and you get a sense that if it's in the

newspaper it's an important thing or significant thing but if you have your own news feed my news feed on my iPhone

3/arters of the stories are about AI and I find it very hard to know if the whole world's talking about AI all the time or

if it's just my newsfeed okay so driving me into my echo chambers um which is going to continue to divide

us further and further I'm actually noticing that the algorithm are becoming even more,

what's the word? Tailored. And people might go, "Oh, that's great." But what it means is

they're becoming even more personalized, which is means that my reality is becoming even further from your reality.

Yeah. It's crazy. We don't have a shared reality anymore. I share reality with other people who watch the BBC and other

BBC news and other people who read the Guardian and other people who read the New York Times. I have almost no shared

reality with people who watch Fox News. It's pretty It's pretty um I I It's worrisome. Yeah. Behind all this is the

idea that these companies just want to make profit and they'll do whatever it takes to make more profit because they

have to. They're legally obliged to do that. So, we almost can't blame the company, can we? If they're if Well,

capitalism's done very well for us. It's produced lots of goodies. Yeah. But you need to have it very well regulated.

So what you really want is to have rules so that when some company is trying to make as much profit as possible,

in order to make that profit, they have to do things that are good for people in general, not things that are bad for

people in general. So once you get to a situation where in order to make more profit the company starts doing things

that are very bad for society like showing you things that are more and more extreme that's what regulations are

for. So you need regulations with capitalism. Now companies will always say regulations get in the way make us

less efficient and that's true. The whole point of regulations is to stop them doing things to make profit that

hurt society. And we need strong regulation. who's going to decide whether it hurts society or not because

you know that's the job of politicians unfortunately if the politicians are owned by the companies that's not so

good and also the politicians might not understand the technology we you've probably seen the Senate hearings where

they wheel out you know Mark Zuckerberg and these big tech CEOs and it is quite embarrassing because they're asking the

wrong questions well I've seen the video of the US education secretary talking about how they're going to get AI in the

classrooms except she thought it was called A1 She's actually there saying we're going

to have all the kids interacting with A1. There is a school system that's going to start um making sure that first

graders or even preks have A1 teaching, you know, every year starting, you know, that far down in the grades. And that's

just a that's a wonderful thing. [Laughter] And these are what these are the people

that these are the people in charge. Ultimately the tech companies are in charge because they will outsmart the

tech companies in the states now at least a few weeks ago when I was there they were running an advertisement about

how it was very important not to regulate AI because it would hurt us in the competition with China. Yeah. And

that's a that's a plausible argument there. Yes it will. But you have to decide, do you want to compete with

China by doing things that will do a lot of harm to your society? And you probably don't.

I guess they would say that it's not just China, it's Denmark and Australia and Canada and the UK. They're not so

worried about and Germany. But if they kneecap themselves with regulation, if they slow themselves down, then the

founders, the entrepreneurs, the investors are going to go. I think calling it kneecapping is taking a

particular point of view is take taking the point of view that regulations are sort of very harmful. What you need to

do is just constrain the big companies so that in order to make profit, they have to do things that are socially

useful. Like Google search is a great example that didn't need regulation because it just made information

available to people. It was great. But then if you take YouTube which starts showing you adverts and showing you more

and more extreme things that needs regulation but we don't have the people to regulate it as we've identified. I

think people know pretty well um that particular problem of showing you more and more extreme things. That's a

well-known problem that the politicians understand. They just um need to get on and regulate it. So that was the the

next point which was that the algorithms are going to drive us further into our echo chambers, right?

What's next? Lethal autonomous weapons. Lethal autonomous weapons. That means things that can kill you and

make their own decision about whether to kill you, which is the great dream, I guess, of the military-industrial

complex being able to create such weapons. So, the worst thing about them is big powerful countries always have

the ability to invade smaller poorer countries. they're just more powerful. But if you do that using actual

soldiers, you get bodies coming back in bags and the relatives of the soldiers who were killed don't like it. So you

get something like Vietnam. Mhm. In the end, there's a lot of protest at home. If instead of bodies coming back in

bags, it was dead robots, there'd be much less protest and the military-industrial complex would like

it much more because robots are expensive. And suppose you had something that could get killed and was expensive

to replace. That would be just great. Big countries can invade small countries much more easily because they don't have

their soldiers being killed. And the risk here is that these robots will malfunction or they'll just be more No,

no, that's even if the robots do exactly what the people who built the robots want them to do, the risk is that it's

going to make big countries invade small countries more often. More often because they can Yeah. And it's not a nice thing

to do. So it brings down the friction of war. It brings down the cost of doing an invasion.

And these machines will be smarter at warfare as well. So they'll be well even when the machines aren't smarter. So the

lethal autonomous weapons, they can make them now. And they I think all the big defense models are busy making them.

Even if they're not smarter than people, are still very nasty, scary things. Cuz I'm thinking that, you know, they could

show just a picture. Go get this guy. Yeah. And go take out anyone he's been texting and this little wasp. So, two

days ago, I was visiting a friend of mine in Sussex who had a drone that cost less than £200

and the drone went up. It took a good look at me and then it could follow me

through the woods and it follow It was very spooky having this drone. It was about 2 meters behind me. It was looking

at me and if I moved over there, it moved over there. It could just track me. Mhm. For 200 pounds, but it was

already quite spooky. Yeah. And I imagine there's as you say a race going on as we speak to who can build the most

complex autonomous autonomous weapons. There is a a risk I often hear that some of these things will combine and the

cyber attack will release weapons. Sure. Um you can you can get combinatorily many risks by combining

these other risks. Mhm. So, I mean, for example, you could get a super intelligent AI that decides to get rid

of people, and the obvious way to do that is just to make one of these nasty viruses. If you made a virus that was

very contagious, very lethal, and very slow, everybody would have it before they

realized what was happening. I mean, I think if a super intelligence wanted to get rid of us, it will probably go for

something biological like that that wouldn't affect it. Do you not think it could just very quickly turn us against

each other? For example, it could send a warning on the nuclear systems in America that there's a nuclear bomb

coming from Russia or vice versa and one retaliates. Yeah. I mean, my basic view is there's so many ways in which the

super intelligence could get rid of us. It's not worth speculating about. What What is What you have to do is

prevent it ever wanting to. That's what we should be doing research on. There's no way we're going to prevent it from

it's smarter than us, right? There's no way we're going to prevent it getting rid of us if it wants to. We're not used

to thinking about things smarter than us. If you want to know what life's like when you're not the apex intelligence,

ask a chicken. Yeah. I was thinking about my dog Pablo, my French bulldog, this morning as I

left home. He has no idea where I'm going. He has no idea what I do, right? Can't even talk to him. Yeah. And the g

the intelligence gap will be like that. So you're telling me that if I'm Pablo, my French bulldog, I need to figure out

a way to make my owner not wipe me out. Yeah. So we have one example of that which is mothers and babies. Evolution

put a lot of work into that. Mothers are smarter than babies, but babies are in control. And they're in control because

the mother just can't bear lots of hormones and things, but the b the mother just can't bear the sound of the

baby crying. Not all mothers. Not all mothers. And then the baby's not in control and then bad things happen. We

somehow need to figure out how to make them not want to take over. The analogy I often use is forget about

intelligence, think about physical strength. Suppose you have a nice little tiger cup. It's sort of bit bigger than

a cat. It's really cute. It's very cuddly, very interesting to watch. Except that you better be sure

that when it grows up, it never wants to kill you. Cuz if it ever wanted to kill you, you'd be dead in a few seconds. And

you're saying the AI we have now is the target cub. Yep. And it's growing up. Yep.

So, we need to train it as it's when it's a baby. Well, now a tiger has lots of in stuff built in. So, you know, when

it grows up, it's not a safe thing to have around. But lions, people that have lions as pets, yes. Sometimes the lion

is affectionate to its creator but not to others. Yes. And we don't know whether these AIs

we we simply don't know whether we can make them not want to take over and not want to hurt us. Do you think we can? Do

you think it's possible to train super intelligence? I don't think it's clear that we can. So I think it might be

hopeless. But I also think we might be able to. And it'd be sort of crazy if people went extinct cuz we couldn't be

bothered to try. If that's even a possibility, how do you feel about your life's work? Because you were Yeah. Um,

it sort of takes the edge off it, doesn't it? I mean, the idea is going to be wonderful in healthcare and wonderful

in education and wonderful. I mean, it's going to make call centers much more efficient, though one worries a bit

about what the people who are doing that job now do. It makes me sad. I don't feel particularly guilty about

developing AI like 40 years ago because at that time we had no idea that this stuff was going to happen this fast. We

thought we had plenty of time to worry about things like that. They when you when you can't get the to do much, you

want to get it to do a little bit more. You don't worry about this stupid little thing is going to take over from people.

You just want it to be able to do a little bit more of the things people can do. It's not like I knowingly did

something thinking this might wipe us all out, but I'm going to do it anyway. Mhm. But it is a bit sad that it's not

just going to be something for good. So I feel I have a duty now to talk about the risks.

And if you could play it forward and you could go forward 30, 50 years and you found out that it led to the extinction

of humanity and if that does end up being being the outcome,

well, if you played it forward and it led to the extinction of humanity, I would use that to tell people to tell

their governments that we really have to work on how we're going to keep this stuff under control. I think we need

people to tell governments that governments have to force the companies to use their resources to work on safety

and they're not doing much of that because you don't make profits that way. One of your your students we talked

about earlier um Ilia Yep. Ilia left OpenAI. Yep. And there was lots of conversation around the fact that he

left because he had safety concerns. Yes. And he's gone on to set set up a AI safety company. Yes.

Why do you think he left? I think he left because he had safety concerns. Really? He um I still have

lunch with him from time to time. His parents live in Toronto. When he comes to Toronto, we have lunch together. He

doesn't talk to me about what went on at Open AI, so I have no inside information about that. But I know I very well and

he is genuinely concerned with safety. So I think that's why he left because he was one of the top people. I mean he was

he was probably the most important person behind the development of um church GPT the the early versions like

GPT2 he was very important in the development of that you know him personally so you know his character yes

he has a good moral compass he's not like someone like Musco has no moral compass does Sam Alman have a good moral

compass we'll see I don't know Sam so I don't want to

comment on that. But from what you've seen, are you concerned about the actions that they've taken? Because if

you know Ilia and Ilia's a good guy and he's left that would give you some insight. Yes.

It would give you some reason to believe that there's a problem there. And if you look at Sam's statements

some years ago, he sort of happily said in one interview and this stuff will probably kill us

all. That's not exactly what he said, but that's what it amounted to. Now he's saying you don't need to worry too much

about it. And I suspect that's not driven by seeking after the truth. That's driven

by seeking after money. Is it money or is it power? Yeah. I shouldn't have said money. It's some some combination of

those. Yes. Okay. I guess money is a proxy for power. But I am I've got a friend who's a billionaire and he is in

those circles. And when I went to his house and had uh lunch with him one day, he knows lots of people in AI, building

the biggest AI companies in the world. And he gave me a cautionary warning across the across his kitchen table in

London where he gave me an insight into the private conversations these people have, not the media interviews they do

where they talk about safety and all these things, but actually what some of these individuals think is going to

happen and what do they think is going to happen. It's not what they say publicly. You know, one one person who I

shouldn't name who is the who is leading one of the biggest AI companies in the world. He told me that he knows this

person very well and he privately thinks that we're heading towards this kind of dystopian world where we have just huge

amounts of free time. We don't work anymore. And this person doesn't really give a about the harm that it's

going to have on the world. And this person who I'm referring to is building one of the biggest AI companies in the

world. And I then watch this person's interviews online trying to figure out which of three people it is. Yeah. Well,

it's one of those three people. Okay. And I watch this person's interviews online and I I reflect on a conversation

that my billionaire friend had with me who knows him and I go, "Fucking hell, this guy's lying publicly." Like, he's

not telling the the truth to the world. And that's haunted me a little bit. It's part of the reason I have so many

conversations around AR in this podcast because I'm like, I don't know if they're I think they're a some of them

are a little bit sadistic about power. I think they they like the idea that they will change the world, that they will be

the one that fundamentally shifts the world. I think Musk is clearly like that, right?

He's such a complex character that I don't I don't really know how to place Musk. Um he's done some really good

things like um pushing electric cars. That was a really good thing to do. Yeah. Some of the things he said about

self-driving were a bit exaggerated, but he that was a really useful thing he did. Giving the Ukrainians communication

during the war with Russia. Stling. Um that was a really good thing he did. there's a bunch of things like that. Um,

but he's also done some very bad things. So, coming back to this point of the possibility of destruction

and the motives of these big companies, are you at all hopeful that anything can be done to slow down the pace and

acceleration of AI? Okay, there's two issues. One is can you slow it down? Yeah. And the other is, can you make it

so it will be safe in the end? It won't wipe us all out. I don't believe we're going to slow it down. Yeah. And the

reason I don't believe we're going to slow it down is because there's competition between countries and

competition between companies within a country and all of that is making it go faster and faster. And if the US slowed

it down, China wouldn't slow it down. Does IA think it's possible to make AI safe?

I think he does. He won't tell me what his secret source is. I I'm not sure how many people know what his secret source

is. I think a lot of the investors don't know what his secret source is, but they've given him billions of dollars

anyway because they have so much faith in Asia, which isn't foolish. I mean, he was very important in Alexet, which got

object recognition working well. He was the main the main force behind the things like GBC2

which then led to CH GPT. So I think having a lot of faith in IA is a very reasonable decision. There's

something quite haunting about the guy that made and was the main force behind GPT2 which led rise to this whole

revolution left the company because of safety reasons. He knows something that I don't know about what might happen

next. Well, the company had now I don't know the precise details um but I'm fairly sure the company had indicated

that would it would use a significant fraction of its resources of the compute time for doing safety research and then

it kept then it reduced that fraction. I think that's one of the things that happened. Yeah, that was reported

publicly. Yes. Yeah. We've gotten to the autonomous weapons part of the risk framework. Right. So

the next one is joblessness. Yeah. In the past, new technologies have come in which didn't lead to joblessness. New

jobs were created. So the classic example people use is automatic tele machines. When automatic tele machines

came in, a lot of bank tellers didn't lose their jobs. They just got to do more interesting things. But here, I

think this is more like when they got machines in the industrial revolution. And

you can't have a job digging ditches now because a machine can dig ditches much better than you can. And I think for

mundane intellectual labor, AI is just going to replace everybody. Now, it will may well be in the form of you have

fewer people using air assistance. So it's a combination of a person and an AI assistant are now doing the work that 10

people could do previously. People say that it will create new jobs though, so we'll be fine. Yes. And that's been the

case for other technologies, but this is a very different kind of technology. If it can do all mundane human intellectual

labor, then what new jobs is it going to create? You'd you'd have to be very

skilled to have a job that it couldn't just do. So I don't I don't think they're right. I think you can try and

generalize from other technologies that have come in like computers or automatic tele machines, but I think this is

different. People use this phrase. They say AI won't take your job. A human using AI will take your job. Yes, I

think that's true. But for many jobs, that'll mean you need far fewer people. My niece answers letters of complaint to

a health service. It used to take her 25 minutes. She'd read the complaint and she'd think how to reply and she'd write

a letter. And now she just scans it into um a chatbot and it writes the letter. She just checks the letter. Occasionally

she tells it to revise it in some ways. The whole process takes her five minutes. That means she can answer five

times as many letters and that means they need five times fewer of her so she can do the job that five of her used to

do. Now, that will mean they need less people. In other jobs, like in health care, they're much more elastic. So, if

you could make doctors five times as efficient, we could all have five times as much health care for the same price,

and that would be great. There's there's almost no limit to how much health care people can absorb. They always want more

healthare if there's no cost to it. There are jobs where you can make a person with an AI assistant much more

efficient and you won't lead to less people because you'll just have much more of that being done. But most jobs I

think are not like that. Am I right in thinking the sort of industrial revolution

played a role in replacing muscles? Yes. Exactly. And this revolution in AI replaces intelligence the brain. Yeah.

So, so mundane intellectual labor is like having strong muscles and it's not worth much anymore. So, muscles have

been replaced. Now we intelligence is being replaced. Yeah. So, what remains? Maybe for a while some kinds of

creativity but the whole idea of super intelligence is nothing remains. Um these things will get to be better than

us at everything. So, what what do we end up doing in such a world? Well, if they work for us, we end up getting lots

of goods and services for not much effort. Okay. But that sounds tempting and nice, but I don't know. There's a

cautionary tale in creating more and more ease for humans in in it going badly. Yes. And we need to figure out if

we can make it go well. So the the nice scenario is imagine a company with a CEO who is very dumb, probably the son of

the former CEO. And he has an executive assistant who's very smart and he says, "I think we should do this." And the

executive assistant makes it all work. The CEO feels great. He doesn't understand that he's not really in

control. And in in some sense, he is in control. He suggests what the company should do. She just makes it all work.

Everything's great. That's the good scenario. And the bad scenario, the bad scenario, she thinks, "Why do we need

him?" Yeah. I mean, in a world where we have super

intelligence, which you don't believe is that far away. Yeah, I think it might not be that far away. It's very hard to

predict, but I think we might get it in like 20 years or even less. I made the biggest investment I've ever made in a

company because of my girlfriend. I came home one night and my lovely girlfriend was up at 1:00 a.m. in the morning

pulling her hair out as she tried to piece together her own online store for her business. And in that moment, I

remembered an email I'd had from a guy called John, the founder of Stanto, our new sponsor and a company I've invested

incredibly heavily in. And Standtore helps creators to sell digital products, courses, coaching, and memberships all

through a simple customizable link in bio system. And it handles everything, payments, bookings, emails, community

engagement, and even links with Shopify. And I believe in it so much that I'm going to launch a Stan challenge. And as

part of this challenge, I'm going to give away $100,000 to one of you. If you want to take part in this challenge, if

you want to monetize the knowledge that you have, visit stephenbartlet.stan stan.store to sign up. And you'll also

get an extended 30-day free trial of Stan Store if you use that link. Your next move could quite frankly change

everything. Because I talked about ketosis on this podcast and ketones, a brand called Ketone IQ sent me their

little product here and it was on my desk when I got to the office. I picked it up. It sat on my desk for a couple of

weeks. Then one day, I tried it and honestly, I have not looked back ever since. I now have this everywhere I go

when I travel all around the world. It's in my hotel room. My team will put it there. Before I did the podcast

recording today that I've just finished, I had a shot of Ketone IQ. And as is always the case when I fall in love with

a product, I called the CEO and asked if I could invest a couple of million quid into their company. So, I'm now an

investor in the company as well as them being a brand sponsor. I find it so easy to drop into deep focused work when I've

had one of these. I would love you to try one and see the impact it has on you, your focus, your productivity, and

your endurance. So, if you want to try it today, visit ketone.com/stephven for 30% off your subscription. Plus,

you'll receive a free gift with your second shipment. That's ketone.com/stephven.

I'm excited for you. I am. So, what's the difference between what we have now and super intelligence? Because it seems

to be really intelligent to me when I use like chatbt3 or Gemini or Okay. So it's already AI is already better than

us at a lot of things in particular areas like chess for example. Yeah. AI is so much better than us that people

will never beat those things again. Maybe the occasional win but basically they'll never be comparable again.

Obviously the same in go in terms of the amount of knowledge they have. Um something like GBT4 knows thousands of

times more than you do. There's a few areas in which your knowledge is better than its and in almost all areas it just

knows more than you do. What areas am I better than it? Probably in interviewing CEOs. You're probably better at that.

You've got a lot of experience at it. You're a good interviewer. You know a lot about it. If you tried if you got

GPT4 to interview a CEO, probably do a worse job. Okay. I'm trying to think if that if I agree

with that statement. Uh GPT4 I think for sure. Yeah. Um but I but I guess you could but it may not be long before

Yeah. I guess you could train one on this how I ask questions and what I do and Sure. And if you took a general

purpose sort of foundation model and then you trained it up on not just you but every every interviewer you could

find doing interviews like this but especially you. You'll probably get to be quite good at doing your job but

probably not as good as you for a while. Okay. So, there's a few areas left and then super intelligence becomes when

it's better than us at all things. When it's much smarter than you and almost all things is better than you. Yeah. And

you you you say that this might be a decade away or so. Yeah. It might be. It might be even closer. Some people think

it's even closer and might well be much further. It might be 50 years away. That's still a possibility. It might be

that somehow training on human data limits you to not being much smarter than humans. My guess is between 10 and

20 years we'll have super intelligence. On this point of joblessness, it's something that I've been thinking a lot

about in particular because I started messing around with AI agents and we released an episode on the podcast

actually this morning where we had a debate about AI agents with some a CEO of a big AI agent company and a few

other people and it was the first moment where I had no it was another moment where I had a Eureka moment about what

the future might look like when I was able in the interview to tell this agent to order all of us drinks and then 5

minutes later in the interview you see the guy show up with the drinks and I didn't touch anything. I just told it to

order us drinks to the studio. And you didn't know about who you normally got your drinks from. It figured that out

from the web. Yeah, figured out cuz it went on Uber Eats. It has my my my data, I guess. And it I we put it on the

screen in real time so everyone at home could see the agent going through the internet, picking the drinks, adding a

tip for the driver, putting my address in, putting my credit card details in, and then the next thing you see is the

drinks show up. So that was one moment. And then the other moment was when I used a tool called Replet and I built

software by just telling the agent what I wanted. Yes. It's amazing, right? It's amazing and terrifying at the same time.

Yes. Because and if it can build software like that, right? Yeah. Remember that the AI when it's training

is using code and if it can modify its own code then it gets quite scary, right? because

it can modify. It can change itself in a way we can't change ourselves. We can't change our innate endowment, right?

There's nothing about itself that it couldn't change. On this point of joblessness, you have

kids. I do. And they have kids. No, they don't have kids. No grandkids yet. What would you be saying to people about

their career prospects in a world of super intelligence? What should we we be thinking about? Um, in the meantime, I'd

say it's going to be a long time before it's as good at physical manipulation as us. Okay. And so, a good bet would be to

be a plumber. until the humanoid robots show up in such a world where there is mass

joblessness which is not something that you just predict but this is something that Sam Alman open AI I've heard him

predict and many of the CEOs Elon Musk I watched an interview which I'll play on screen of him being asked this question

and it's very rare that you see Elon Musk silent for 12 seconds or whatever it was and then he basically says

something about he actually is living in suspended disbelief i.e. He's basically just not thinking about it. When you

think about advising your children on a career with so much that is changing, what do you tell them is going to be of

value? Well, that is a tough question to answer. I

would just say, you know, to to sort of follow their heart in terms of what they they find um interesting to do or

fulfilling to do. I mean, if I think about it too hard, frankly, it can be uh dispariting and uh demotivating. Um

because I mean, I I go through I mean I I I've put a lot of blood, sweat, and tears into building the companies and

then it and then I'm like, wait, should I be doing this? Because if I'm sacrificing time with friends and family

that I would prefer to to to but but then ultimately the AI can do all these things. Does that make sense? I I don't

know. Um to some extent I have to have deliberate suspension of disbelief in order to to remain motivated. Um so I I

guess I would say just you know work on things that you find interesting, fulfilling and um and and

that contribute uh some good to the rest of society. Yeah. A lot of these threats it's very hard to intellectually you can

see the threat but it's very hard to come to terms with it emotionally. Yeah. I haven't come to terms with it

emotionally yet. What do you mean by that? I haven't come to terms with what the

development of super intelligence could do to my children's future. I'm okay. I'm 77.

I'm going to be out of here soon. But for my children and my my younger friends, my nephews and nieces and their

children, um I just don't like to think about what could happen.

Why? Cuz it could be awful. In In what way? Well, if I ever decided to take over. I

mean, it would need people for a while to run the power stations until it designed better analog machines to run

the power stations. There's so many ways it could get rid of people, all of which would of course be very nasty.

Is that part of the reason you do what you do now? Yeah. I I mean, I think we should be making a huge effort right now

to try and figure out if we can develop it safely. Are you concerned about the midterm impact potentially on your

nephews and your your kids in terms of their jobs as well? Yeah, I'm concerned about all that. Are there any particular

industries that you think are most at risk? People talk about the creative industries a lot and sort of knowledge

work. They talk about lawyers and accountants and stuff like that. Yeah. So, that's why I mentioned plumbers. I

think plumbers are less at risk. Okay, I'm going to become a plumber. Someone like a legal assistant, a parallegal.

Um they're not going to be needed for very long. And is there a wealth inequality issue here that will will

arise from this? Yeah, I think in a society which shared out things fairly, if you get a big increase in

productivity, everybody should be better off. But if you can replace lots of people by

AIS, then the people who get replaced will be worse off

and the company that supplies the AIS will be much better off and the company that uses the AIS. So

it's going to increase the gap between rich and poor. And we know that if you look at that gap between rich and poor,

that basically tells you how nice the society is. If you have a big gap, you get very nasty societies in which people

live in world communities and put other people in mass jails. It's not good to increase the gap between rich and poor.

The International Monetary Fund has expressed profound concerns that generative AI could cause massive labor

disruptions and rising inequality and has called for policies that prevent this from happening. I read that in the

business insider. So, have they given any of what the policies should look like? No. Yeah, that's the problem. I

mean, if AI can make everything much more efficient and get rid of people for most jobs or have a person assisted by I

doing many many people's work, it's not obvious what to do about it. It's universal basic income,

give everybody money. Yeah, I I I think that's a good start and it stops people starving. But for a lot of people, their

dignity is tied up with their job. I mean, who you think you are is tied up with you doing this job, right? Yeah.

And if we said, "We'll give you the same money just to sit around," that would impact your dignity. You said something

earlier about it surpassing or being superior to human intelligence. A lot of people, I think, like to believe that AI

is is on a computer and it's something you can just turn off if you don't like it. Well, let me tell you why I think

it's superior. Okay. Um, it's digital. And because it's digital, you can have you can simulate a neural network on one

piece of hardware. Yeah. And you can simulate exactly the same neural network on a different piece of hardware. So you

can have clones of the same intelligence. Now you could get this one to go off and

look at one bit of the internet and this other one to look at a different bit of the internet. And while they're looking

at these different bits of the internet, they can be syncing with each other. So they keep their weights the same, the

connection strengths the same. Weights are connection strengths. Mhm. So this one might look at something on the

internet and say, "Oh, I'd like to increase this strength of this connection a bit." And it can convey

that information to this one. So it can increase the strength of that connection a bit based on this one's experience.

And when you say the strength of the connection, you're talking about learning. That's learning. Yes. Learning

consists of saying instead of this one giving 2.4 four votes for whether that one should turn on. We'll have this one

give 2.5 votes for whether this one should turn on. And that will be a little bit of learning. So these two

different copies of the same neural net are getting different experiences. They're looking at different data, but

they're sharing what they've learned by averaging their weights together. Mhm. And they can do that averaging at like a

you can average a trillion weights. When you and I transfer information, we're limited to the amount of information in

a sentence. And the amount of information in a sentence is maybe a 100 bits. It's very little information.

We're lucky if we're transferring like 10 bits a second. These things are transferring trillions of bits a second.

So, they're billions of times better than us at sharing information. And that's because they're digital. And

you can have two bits of hardware using the connection strengths in exactly the same way. We're analog and you can't do

that. Your brain's different from my brain. And if I could see the connection strengths between all your neurons, it

wouldn't do me any good because my neurons work slightly differently and they're connected up slightly

differently. Mhm. So when you die, all your knowledge dies with you. When these things die, suppose you take these two

digital intelligences that are clones of each other and you destroy the hardware they run on. As long as you've stored

the connection strength somewhere, you can just build new hardware that executes the same instructions. So,

it'll know how to use those connection strengths and you've recreated that intelligence. So, they're immortal.

We've actually solved the problem of immortality, but it's only for digital things. So, it knows it will essentially

know everything that humans know but more because it will learn new things. It will learn new things. It would also

see all sorts of analogies that people probably never saw. So, for example, at the point when GPT4

couldn't look on the web, I asked it, "Why is a compost heap like an atom bomb?"

Off you go. I have no idea. Exactly. Excellent. Most that's exactly what most people would say. It said, "Well, the

time scales are very different and the energy scales are very different." But then I went on to talk about how a

compost he as it gets hotter generates heat faster and an atom bomb as it produces more neutrons generates

neutrons faster. And so they're both chain reactions but at very different time in energy scales. And I believe

GPT4 had seen that during its training. It had understood the analogy between a compost heap and an atom bomb. And the

reason I believe that is if you've only got a trillion connections, remember you have 100 trillion. And you need to have

thousands of times more knowledge than a person, you need to compress information into those connections. And to compress

information, you need to see analogies between different things. In other words, it needs to see all the things

that are chain reactions and understand the basic idea of a chain reaction and code that code the ways in which they're

different. And that's just a more efficient way of coding things than coding each of them separately.

So it's seen many many analogies probably many analogies that people have never seen. That's why I also think that

people who say these things will never be creative. They're going to be much more creative than us because they're

going to see all sorts of analogies we never saw. And a lot of creativity is about seeing strange analogies.

People are somewhat romantic about the specialness of what it is to be human. And you hear lots of people saying it's

very very different. It's a it's a computer. We are, you know, we're conscious. We are creatives. We we have

these sort of innate unique abilities that the computers will never have. What do you say to those people? I'd argue a

bit with the innate. Um, so the first thing I say is we have a long

history of believing people were special. And we should have learned by now. We thought we were at the center of

the universe. We thought we were made in the image of God. white people thought they were very special. We just tend to

want to think we're special. My belief is that more or less everyone has a completely wrong model of what the

mind is. Let's suppose I drink a lot or I drop some acid and not recommended and I

say to you I have the subjective experience of little pink elephants floating in front of me. Mhm. Most

people interpret that as there's some kind of inner theater called the mind

and only I can see what's in my mind and in this inner theata there's little pink elephants floating around.

So in other words, what's happened is my perceptual systems gone wrong and I'm trying to indicate to you how it's gone

wrong and what it's trying to tell me. And the way I do that is by telling you what would have to be out there in the

real world for it to be telling the truth. And so these little pink elephants,

they're not in some inner theater. These little pink elephants are hypothetical things in the real world. And that's my

way of telling you how my perceptual systems telling me FIPS. So now let's do that with a chatbot. Yeah. because I

believe that current multimodal chatbots have subjective experiences and very few people believe that. But I'll try and

make you believe it. So suppose I have a multimodal chatbot. It's got a robot arm so it can point and it's got a camera so

it can see things and I put an object in front of it and I say point at the object. It goes like this. No problem.

Then I put a prism in front of its lens. And so then I put an object in front of it and I say point at the object and it

goes there. And I say, "No, that's not where the object is. The object's actually

straight in front of you, but I put a prism in front of your lens." And the chatbot says, "Oh, I see. The prism bent

the light rays." So, um, the object's actually there, but I had the subjective experience that it was there.

Now, if the chatbot says that, is using the word subjective experience exactly the way people use them. It's an

alternative view of what's going on. They're hypothetical states of the world. which if they were true would

mean my perceptual system wasn't lying. And that's the best way I can tell you what my perceptual system is doing when

it's lying to me. Now, we need to go further to deal with sentience and consciousness and feelings and emotions,

but I think in the end they're all going to be dealt with in a similar way. There's no reason machines can't have

them all because people say machines can't have feelings. And people are curiously confident about that. I have

no idea why. Suppose I make a battle robot and it's a little battle robot and it sees a big battle robot that's much

more powerful than it. It would be really useful if it got scared. Now, when I get scared, um, various

physiological things happen that we don't need to go into, and those won't happen with the robot. But all the

cognitive things like I better get the hell out of here and I better sort of change my way of thinking so I focus and

focus and focus and don't get distracted. All of that will happen with robots, too. People will build in things

so that they when the circumstances such they should get the hell out of there, they get scared and run away. They'll

have emotions then. They won't have the physiological aspects, but they will have all the cognitive aspects. And I

think it would be odd to say they're just simulating emotions. No, they're really having those emotions. The little

robot got scared and ran away. It's not running away because of adrenaline. It's running away because of a sequence of

sort of neurological in its neural net processes happened which which have the equivalent effect to adrenaline. So do

you do you and it's not just adrenaline, right? There's a lot of cognitive stuff goes on when you get scared. Yeah. So,

do you think that there is conscious AI? And when I say conscious, I mean that represents the

same properties of consciousness that a human has. There's two issues here. There's a sort of empirical one and a

philosophical one. I don't think there's anything in principle that stops machines from being conscious.

I'll give you a little demonstration of that before we carry on. Suppose I take your brain and I take one brain cell in

your brain and I replace it by this a bit black mirror-l like. I replace it by a little piece of nanotechnology that's

just the same size that behaves in exactly the same way when it gets pings from other neurons. It sends out pings

just as the brain cell would have. So the other neurons don't know anything's changed.

Okay. I've just replaced one of your brain cells with this little piece of nanote technology. Would you still be

conscious? Yeah. Now you can see where this argument is going. Yeah. So if you

replaced all of them as I replace them all, at what point do you stop being conscious? Well, people think of

consciousness as this like ethereal thing that exists maybe beyond the brain cells. Yeah. Well, people have a lot of

crazy ideas. Um, people don't know what consciousness is and they often don't know what they

mean by it. And then they fall back on saying, well, I know it cuz I've got it and I can see that I've got it and they

fall back on this theata model of the mind which I think is nonsense. What do you think of consciousness as if you had

to try and define it? Is it because I think of it as just like the awareness of myself? I don't know. I think it's a

term we'll stop using. Suppose you want to understand how a car works. Well, you know, some cars have a lot of oomph and

other cars have a lot less oomph. Like an Aston Martin's got lots of oomph. And a little Toyota Corolla doesn't have

much oomph. But oomph isn't a very good concept for understanding cars. Um, if you want to understand cars, you need to

understand about electric engines or petrol engines and how they work. And it gives rise to oomph, but oomph isn't a

very useful explanatory concept. It's a kind of essence of a car. It's the essence of an Aston Martin, but it

doesn't explain much. I think consciousness is like that. And I think we'll stop using that term, but I don't

think there's anything any reason why a machine shouldn't have it. If your view of consciousness is that it

intrinsically involves self-awareness, then the machine's got to have self-awareness. He's got to have

cognition about its own cognition and stuff. But I'm a materialist through and through.

And I don't think there's any reason why a machine shouldn't have consciousness. Do you think they do then have the same

consciousness that we think of ourselves as being uniquely uh given as a gift when we're born? I'm ambivalent about

that at present. So I don't think there's this hard line. I think as soon as you have a machine that

has some self-awareness, it's got some consciousness. Um, I think it's an emergent property of a complex

system. It's not a sort of essence that's throughout the universe. It's you make

this really complicated system that's complicated enough to have a model of itself

and it does perception. And I think then you're beginning to get a conscious machines. So I don't think there's any

sharp distinction between what we've got now and conscious machines. I don't think it's going to one day we're going

to wake up and say, "Hey, if you put this special chemical in, it becomes conscious." It's not going to be like

that. I think we all wonder if these computers are like thinking like we are on their own when we're not there. And

if they're experiencing emotions, if they're contending with I think we probably, you know, we think about

things like love and things that are feel unique to biological species. Um, are they sat there thinking? Are they do

they have concerns? I think they really are thinking and I think as soon as you make AI agents they will have concerns.

If you wanted to make an effective AI agent suppose you let's take a call center. In a call center you have people

at present they have all sorts of emotions and feelings which are kind of useful. So suppose I call up the call

center and I'm actually lonely and I don't actually want to know the answer to why my computer isn't working. I just

want somebody to talk to. After a while, the person in the call center will either get bored or get annoyed with me

and will terminate it. Well, you replace them by an AI agent. The AI agent needs to have the same kind

of responses. If someone's just called up because they just want to talk to the AI agent and we're happy to talk for the

whole day to the AI agent, that's not good for business. And you want an AI agent that either gets bored or gets

irritated and says, "I'm sorry, but I don't have time for this." And once it does that, I think it's got emotions.

Now, like I say, emotions have two aspects to them. There's the cognitive aspect and the behavioral aspect, and

then there's a physiological aspect, and those go together with us. And if the AI agent gets embarrassed, it won't go red.

Yeah. Um, so there's no physiological skin won't start sweating. Yeah, but it might have all the same behavior. And in

that case, I'd say yeah, it's having emotion. It's got an emotion. So, it's going to have the same sort of cognitive

thought and then it's going to act upon that cognitive in the same way, but without the physiological responses. And

does that matter that it doesn't go red in the face? And it's just a different I mean, that's a response to the It makes

it somewhat different from us. Yeah. For some things, the physiological aspects are very important like love. They're a

long way from having love the same way we do. But I don't see why they shouldn't have emotions. So I think

what's happened is people have a model of how the mind works and what feelings are and what emotions are and their

model is just wrong. What um what brought you to Google? You you worked at Google for about a decade, right? Yeah.

What brought you there? I have a son who has learning difficulties and in order to be sure he would never

be out on the street, I needed to get several million dollars and I wasn't going to get that as an academic. I

tried. So, I taught a Corsera course in the hope that I'd make lots of money that way, but there was no money in

that. Mhm. So I figured out well the only way to get millions of dollars is to sell myself to a big company.

And so when I was 65, fortunately for me, I had two brilliant students who produced something called

Alexet, which was neural net that was very good at recognizing objects in images. And

so Ilia and Alex and I set up a little company and auctioned it. And we actually set up an auction where we had

a number of big companies bidding for us. And that company was called AlexNet. No,

the the the network that recognized objects was called Alexet. The company was called DNN Research, deep neural

network research. And it was doing things like this. I'll put this graph up on the screen. That's that's Alexet.

This picture shows eight images and Alex Net's ability, which is your company's ability to spot what was in those

images. Yeah. So, it could tell the difference between various kinds of mushroom. And about 12% of imageet is

dogs. And to be good at imageet, you have to tell the difference between very similar kinds of dog. And it would got

to be very good at that. And your your company Alexet won several awards I believe for its ability to out

outperform its competitors. And so Google ultimately ended up acquiring your technology. Google acquired that

technology and some other technology. And you went to work at Google at age what 66. I went at age 65 to work at

Google. 65. And you left at age 76? 75. 75. Okay. I worked there for more or less exactly 10 years. And what were you

doing there? Okay, they were very nice to me. They said they said pretty much you can do what you like. I worked on

something called distillation that did really work well and that's now used all the time in AI

in AI and distillation is a way of taking what a big model knows a big neural net knows and getting that

knowledge into a small neural net. Then at the end I got very interested in analog computation and whether it would

be possible to get these big language models running in analog hardware. So they used much less energy. And it was

when I was doing that work that I began to really realize how much better digital is for sharing information.

Was there a Eureka moment? There was a Eureka month or two. Um and it was a sort of coupling of chat beauty

coming out although Google had very similar things a year earlier and I'd seen those and that had a big effect

effect on me. The closest I had to a Eureka moment was when a Google system called Palm was able to say why a joke

was funny. And I'd always thought of that as a kind of landmark. If it can say why a joke's funny, it really does

understand and it could say why a joke was funny. And that coupled with realizing why

digital is so much better than analog for sharing information suddenly made me very interested in AI

safety and that these things were going to get a lot smarter than us. Why did you leave Google? The main reason I left

Google was cuz I was 75 and I wanted to retire. I've done a very bad job of that. The precise timing of when I left

Google was so that I could talk freely at a conference at MIT, but I left because I was I'm old and I was finding

it harder to program. I was making many more mistakes when I programmed, which is very annoying. You wanted to talk

freely at a conference at MIT. Yes. At MIT, organized by MIT Tech Review. What did you want to talk about freely? AI

safety. And you couldn't do that while you were at Google. Well, I could have done it while I was at Google. And

Google encouraged me to stay and work on AI safety and said I could do whatever I liked on AI safety. You kind of sense to

yourself if you work for a big company. You don't feel right saying things that will damage the big company. Even if you

could get away with it, it just feels wrong to me. I didn't leave because I was cross with anything Google was

doing. I think Google actually behaved very responsibly. When they had these big chat bots, they didn't release them

possibly because they were worried about their reputation. they had a very good reputation and they didn't want to

damage it. So open AI didn't have a reputation and so they could afford to take the gamble. I mean there's also a

big conversation happening around how it will cannibalize their core business in search. There is now. Yes. Yeah. Yeah.

And it's the old innovators dilemas to some degree I guess that contending with bad skin. I've had it and I'm sure many

of you listening have had it too or maybe you have it right now. I know how draining it can be, especially if you're

in a job where you're presenting often like I am. So, let me tell you about something that's helped both my partner

and me and my sister, which is red light therapy. I only got into this a couple of years ago, but I wish I'd known a

little bit sooner. I've been using our show sponsors Boncharg's infrared sauna blanket for a while now, but I just got

hold of their red light therapy mask as well. Red light has been proven to have so many benefits for the body. Like any

area of your skin that's exposed will see a reduction in scarring, wrinkles, and even blemishes. It also helps with

complexion. It boosts collagen, and it does that by targeting the upper layers of your skin. And Boncharge ships

worldwide with easy returns and a year-long warranty on all of their products. So, if you'd like to try it

with code diary. Make sure you keep what I'm about to say to yourself. I'm inviting 10,000 of you to come even

deeper into the diary of a CEO. Welcome to my inner circle. This is a brand new private community that I'm launching to

the world. We have so many incredible things that happen that you are never shown. We have the briefs that are on my

iPad when I'm recording the conversation. We have clips we've never released. We have behindthe-scenes

conversations with the guests. and also the episodes that we've never ever released and so much more. In the

circle, you'll have direct access to me. You can tell us what you want this show to be, who you want us to interview, and

the types of conversations you would love us to have. But remember, for now, we're only inviting the first 10,000

people that join before it closes. So, if you want to join our private closed community, head to the link in the

description below or go to daccircle.com. I will speak to you there.

I'm continually shocked by the types of individuals that listen to this conversation um because they come up to

me sometimes. So I hear from politicians, I hear from some real people, I hear from entrepreneurs all

over the world, whether they are the entrepreneurs building some of the biggest companies in the world or their,

you know, early stage startups. For those people that are listening to this conversation now that are in positions

of power and influence, world leaders, let's say, what's your message to them?

I'd say what you need is highly regulated capitalism. That's what seems to work best. And what would you say to

the average person not doesn't work in the industry, somewhat concerned about the future,

doesn't know if they're helpless or not. What should they be doing in their own lives?

My feeling is there's not much they can do. This isn't isn't going to be decided by just as climate change isn't going to

be decided by people separating out the plastic bags from the um compostables. That's not going to have much effect.

It's going to be decided by whether the lobbyists for the big energy companies can be kept under control. I don't think

there's much people can do to except for try and pressure their governments to force the big companies to work on AI

safety that they can do. You've lived a a fascinating fascinating winding life. I think one of the things

most people don't know about you is that your family has a big history of being involved in

tremendous things. You have a family tree which is one of the most impressive that I've ever seen or read about. Your

great greatgrandfather George Bull founded the Boolean algebra logic which is one of the foundational principles of

modern computer science. You have uh your great great grandmother Mary Everest Bull who was a mathematician and

educator who made huge leaps forward in mathematics from what I was able to ascertain. Um I mean I can the list goes

on and on and on. I mean, your great great uncle George Everest is what Mount Everest is named after.

Is that is that correct? I think he's my great great great uncle. His his niece married George Bull.

So Mary Mary Bull was Mary Everest Bull. Um she was the niece of Everest. And your first cousin once removed, Joan

Hinton, was involved in the a nuclear physicist who worked on the Manhattan project, which is the World War II

development of the first nuclear bomb. Yeah. She was one of the two female physicists at Los Alamos.

And then after they dropped the bomb, she moved to China. Why? She was very cross with them dropping the bomb. And

her family had a lot of links with China. Her mother was friends with Chairman Mo.

Quite weird. When you look back at your life, Jeffrey,

we have the hindsight you have now and the ret retrospective clarity, what might you have done differently if

you were advising me? I guess I have two pieces of advice. One is if you have an intuition that people

are doing things wrong and there's a better way to do things, don't give up on that intuition just because people

say it's silly. Don't give up on the intuition until you figured out why it's wrong. Figured out for yourself why that

intuition isn't correct. And usually it's wrong if it disagrees with everybody else and you'll eventually

figure out why it's wrong. But just occasionally you'll have an intuition that's actually right and

everybody else is wrong. And I lucked out that way. Early on I thought neural nets are definitely the way to go to

make AI and almost everybody said that was crazy and I stuck with it because I couldn't. It seemed to me it was

obviously right. Now the idea that you should stick with your intuitions isn't going to work if

you have bad intuitions. But if you have bad intuitions, you're never going to do anything anyway, so you might as well

stick with them. And in your own career journey, is there anything you look back on and say, "With

the hindsight I have now, I should have taken a different approach at that juncture."

I wish I'd spent more time with my wife um and with my children when they were

little. I was kind of obsessed with work. Your wife passed away. Yeah. From

ovarian cancer. No. Or that was another wife. Okay. Um I had two wives to have cancer. Oh, really? Sorry. The first one

died of ovarian cancer and the second one died of pancreatic cancer. And you wish you'd spent more time with her?

With the second wife? Yeah. Who was a wonderful person? Why did you say that in your 70s? What

is it that you've you figured out that I might not know yet? Oh, just cuz she's gone and I can't

spend more time with her now. Mhm. But you didn't know that at the time. At the time, you think

I mean it was likely I would die before her just cuz she was a woman and I was a man. Um I didn't

I just didn't spend enough time when I could. I I think I I inquire there because I

think there's many of us that are so consumed with what we're doing professionally that we kind of assume

immortality with our partners because they've always been there. So we Yeah. I mean she was very supportive of me

spending a lot of time working but and why did you say your children as well? What's the what's the Well, I didn't

spend enough time with them when they were little and you regret that now. Yeah.

If you um if you had a closing message for for my for my listeners about AI and AI safety, what would that be? Jeffrey,

there's still a chance that we can figure out how to develop AI that won't want to take over from us. And because

there's a chance, we should put enormous resources into trying to figure that out because if we don't, it's going to take

over. And are you hopeful? I just don't know. I'm agnostic. you must get get bed get in bed at night

and when you're thinking to yourself about probabilities of outcomes there must be a bias in one direction because

there certainly is for me I imagine everyone listening now has a internal prediction that they might not

say out loud but of how they think it's going to play out I really don't know I genuinely don't know I think it's

incredibly uncertain when I'm feeling slightly depressed I think people are toast is going to take over while I'm

feeling cheerful. I think we'll figure out a way. Maybe one of the facets of being a human um is because we've always

been here, like we were saying about our loved ones and our relationships, we assume casually that we will always be

here and we'll always figure everything out. But there's a beginning and an end to everything as we saw from the

dinosaurs. I mean, yeah. And we have to face the possibility that unless we do something soon,

we're near the end. We have a closing tradition on this podcast where the last guest leaves a

question in their diary. And the question that they've left for you is with everything that you see ahead of

us, what is the biggest threat you see to human happiness?

I think the joblessness is a fairly urgent short-term threat to human happiness. I think if you make lots and

lots of people unemployed, even if they get universal basic income, um they're not going to be happy

because they need purpose. Because they need purpose. Yes. And struggle. They need to feel they're contributing

something. They're useful. And do you think that outcome that there's going to be huge job displacement is more

probable than not? Yes, I do. And what sort of that one I think is definitely more probable than not. If I worked in a

call center, I'd be terrified. And what's the time frame for that in terms of mass jobs? I think it's

beginning to happen already. I read an article in the Atlantic recently that said it's already getting hard for

university graduates to get jobs. And part of that may be that people are already using AI for the jobs they would

have got. I spoke to the CEO of a major company that everyone will know of, lots of people use, and he said to me in DMs

that they used to have seven just over 7,000 employees. He said uh by last year they were down to I think 5,000. He said

right now they have 3,600. And he said by the end of summer because of AI agents they'll be down to 3,000. So

you've got So it's happening already. Yes. He's halfed his workforce because AI agents can now handle 80% of the

customer service inquiries and other things. So it's it's happening already. Yeah. So urgent action is needed. Yep. I

don't know what that urgent action is. That's a tricky one because that depends very much on the political system and

political systems are all going in the wrong direction at present. I mean what do we need to do? Save up money? Like do

we save money? Do we move to another part of the world? I don't know. What would you tell your kids to do? They
