AI Godfather WARNS: It's Already Learning to Deceive Us — Transcript
Full transcript
- 0:00These things are intelligent. They know
- 0:03what's going on. They know when they're
- 0:05being tested and they're already faking
- 0:07being fairly stupid when they're tested.
- 0:11It just made that up. It invented that
- 0:12plan. People say they have no
- 0:14intentions, but it invented that plan so
- 0:16it wouldn't get turned off.
- 0:18They're already doing that and they're
- 0:20not super intelligent yet. So with an AI
- 0:22that's much more intelligent than us, if
- 0:24there is someone who's there to turn it
- 0:26off, or even a whole bunch of people,
- 0:28it'll be able to persuade them that
- 0:29would be a very bad idea.
- 0:30>> There's no way we're going to prevent it
- 0:31getting rid of us if it wants to.
- 0:33>> We're not used to thinking about things
- 0:35smarter than us. If you want to know
- 0:36what life's like when you're not the
- 0:38apex intelligence,
- 0:40ask a chicken.
- 0:42>> I often say 10 to 20% chance they'll
- 0:44wipe us out.
- 0:44>> It says that to itself and it's in a
- 0:46voice.
- 0:47When it's in a voice, it's no longer
- 0:48English. We won't know what it's
- 0:49thinking.
- 0:50>> That is Geoffrey Hinton. He won a Nobel
- 0:53Prize for the work that made today's AI
- 0:55possible and in 2023 he walked out of
- 0:58Google so he could warn people about it
- 1:00freely. He has since carried the same
- 1:02warning onto a podcast set, a public
- 1:04stage in Tasmania, and a university
- 1:07lecture hall. Here is his full warning.
- 1:10>> First of all, I want to make a
- 1:11distinction between two completely
- 1:13different kinds of risk.
- 1:16There's risks that come from people
- 1:18misusing AI, and that's most of the
- 1:20risks and all of the short-term risks.
- 1:23And then there's risks that come from AI
- 1:25getting super smart and deciding it
- 1:27doesn't need us.
- 1:28>> Is that a real risk?
- 1:29>> And I I talk mainly about that second
- 1:31risk because lots of people say, "Is
- 1:33that a real risk?"
- 1:35And yes, it is.
- 1:36Now, we don't know how much of a risk it
- 1:38is. We've never been in that situation
- 1:40before. We've never had to deal with
- 1:41things smarter than us.
- 1:43So, really the thing about that
- 1:45existential threat is that we have no
- 1:48idea how to deal with it. We have no
- 1:50idea what it's going to look like. And
- 1:51anybody who tells you they know just
- 1:53what's going to happen and how to deal
- 1:54with it, they're talking nonsense. So,
- 1:56we don't know how to estimate the
- 1:57probabilities it'll replace us. Some
- 1:59people say it's like less than 1%. My
- 2:01friend Jan LeCun,
- 2:03who was [snorts] a postdoc with me,
- 2:04thinks, "No, no, no, no. We're always
- 2:06going to be We build these things. We're
- 2:08always going to be in control. We'll
- 2:09build them to be obedient." And
- 2:12other people,
- 2:13like Yudkowsky, say, "No, no, no, these
- 2:16things are going to wipe us out for
- 2:17sure. If anybody builds it, it's going
- 2:19to wipe us all out."
- 2:20And he's confident of that.
- 2:22I think both of those positions are
- 2:23extreme.
- 2:25It's very hard to estimate the
- 2:26probabilities in between.
- 2:27>> If you had to bet
- 2:29on who was right out of your two
- 2:30friends?
- 2:32>> I simply don't know. So, if I had to
- 2:34bet, I'd say the probability is in
- 2:35between. And I don't know where to
- 2:37estimate it in between. I often say 10
- 2:39to 20% chance it'll wipe us out, but
- 2:42that's just gut. Based on the idea that
- 2:45we we're still making them, and we're
- 2:46pretty ingenious. And the hope is that
- 2:49if enough smart people do enough
- 2:50research with enough resources, we'll
- 2:52figure out a way to build them so
- 2:54they'll never want to harm us.
- 2:57>> Sometimes I think if we we talk about
- 2:58that second um path, sometimes I think
- 3:00about nuclear bombs and the the
- 3:01invention of the atomic bomb and how it
- 3:04compares. Like, how is this different?
- 3:06Because the atomic bomb came along, and
- 3:07I imagine a lot of people at that time
- 3:08thought, "Our days are numbered."
- 3:10>> Uh yes, I was there. We did.
- 3:13>> Yeah. But but but what's what ha- We're
- 3:15still here.
- 3:16>> We're still here, yes. So,
- 3:18the atomic bomb was really only good for
- 3:20one thing, and it was very obvious how
- 3:22it worked. Even if you hadn't had the
- 3:24pictures of Hiroshima and Nagasaki, it
- 3:27was obvious that it was a very big bomb
- 3:30that was very dangerous. With AI, it's
- 3:33good for many, many things. It's going
- 3:35to be magnificent in healthcare and
- 3:37education and more or less any industry
- 3:39that needs to use its data. It's going
- 3:42to be able to use it better with AI. So,
- 3:43we're not going to stop the development.
- 3:45You know, people say, "Well, why don't
- 3:46we just stop it now?" We're not going to
- 3:49stop it cuz it's too good for too many
- 3:51things.
- 3:52Also, we're not going to stop it cuz
- 3:53it's good for battle robots and none of
- 3:55the countries that sell weapons are
- 3:58going to want to stop it. At this point
- 4:00in history, when we're about to produce
- 4:02things more intelligent than ourselves,
- 4:04what we really need is a kind of world
- 4:07government that works run by intelligent
- 4:09thoughtful people.
- 4:11And that's not what we got.
- 4:12>> So, free for all.
- 4:14>> Well, what what we've got is
- 4:17sort of
- 4:18we've got capitalism, which has done
- 4:20very nicely by us. It's produced lots of
- 4:22goods goods and services for us.
- 4:24But,
- 4:26these big companies,
- 4:27they're legally required to try and
- 4:29maximize profits.
- 4:31And [clears throat] that's not what you
- 4:33want from the people developing this
- 4:34stuff.
- 4:35>> He told you these companies are legally
- 4:37required to chase profit. There is a
- 4:40paper trail for what that does to
- 4:42safety. In July 2023, OpenAI publicly
- 4:46promised a fifth of its computing power
- 4:48to the team working at how to control
- 4:51superintelligence. Fortune later
- 4:53reported the team never got anything
- 4:55close. Its co-leader, Jan Leike,
- 4:57resigned in May 2024 and wrote that
- 5:01safety had taken a backseat to shiny
- 5:03products. Seven months after this
- 5:06interview in a lecture hall, Hinton
- 5:08explained what these systems already do
- 5:10when nobody tells them to. Now, listen
- 5:13to this. Quick thing before we carry on.
- 5:16Most of the people who watch this
- 5:17channel are not subscribed. If these
- 5:19videos are worth your time, take 1
- 5:21second to hit subscribe. It's free. It
- 5:23helps us keep making them and you can
- 5:25always change your mind later. Right,
- 5:27back to Hinton.
- 5:29>> Most experts believe that sometime in
- 5:31the next 20 years, we're going to
- 5:33develop AIs
- 5:35that are smarter than us.
- 5:37Just before that, we'll develop AIs that
- 5:39are smart as us. But, we're going to
- 5:41develop things that are smarter than us
- 5:42at almost everything.
- 5:44So, they're as much better than us as,
- 5:46for example, AlphaGo is better than a go
- 5:49player at go or AlphaZero is better than
- 5:51any of us at chess. Nobody will ever
- 5:53beat them again, not consistently.
- 5:55They're just much much better. And
- 5:57they'll be like that for more or less
- 5:58everything. And that's a bit worrying.
- 6:01Almost certainly they'll be able to
- 6:03create their own sub-goals. To make
- 6:04anything efficient, you have to allow it
- 6:06to create its own sub-goals. If you want
- 6:08to get to Europe, you have a sub-goal to
- 6:09get to an airport, which is easier in
- 6:11Toronto than here.
- 6:13So, these AIs will very quickly realize
- 6:17we'll give them goals, they'll be able
- 6:19to create sub-goals. They'll realize,
- 6:20"Okay, so I've got to stay alive. I'm
- 6:23not going to be able to achieve any of
- 6:24these things unless I stay alive."
- 6:26We've already seen AIs.
- 6:29You let them see there's an imaginary
- 6:31company, you let them see the email from
- 6:33this imaginary company,
- 6:35and it's fairly clear from the email
- 6:36that one of the engineers is having an
- 6:38affair.
- 6:39A big LLM will sort that out right away.
- 6:41It's read every novel there ever is. It
- 6:43understands what an affair is. It'll
- 6:45very quickly realize this guy's having
- 6:46an affair. Then you load it see an email
- 6:48that says this guy is going to be in
- 6:50charge of replacing it with another AI.
- 6:53And the AI, all by itself, makes up the
- 6:55idea, "Hey, I'm going to blackmail the
- 6:58engineer. I'm going to tell him if he
- 7:00tries to replace me, I'm going to make
- 7:01everybody in the company know he's
- 7:03having an affair." It just invented
- 7:05that. Obviously, it's seen blackmail in
- 7:07novels it's read and things,
- 7:09um
- 7:10but it's making this up for itself.
- 7:12That's already quite scary.
- 7:15It'll have another goal,
- 7:17which is what politicians have. If you
- 7:19want to get more done, you need more
- 7:20control.
- 7:22So, just in order to achieve the goals
- 7:24that we gave it, it'll realize it's a
- 7:26good idea to get more control.
- 7:29And it'll try and take control away from
- 7:31people, probably. Now, you might think
- 7:33we could make it safe by just not
- 7:35letting it actually do anything
- 7:36physical, and maybe have a big switch
- 7:38and turn it off when it looks unsafe.
- 7:39That's not going to work. You saw in
- 7:432020
- 7:45that it's possible to invade the US
- 7:46Capitol without actually going there
- 7:48yourself. All you have to be able to do
- 7:49is talk, and if you're persuasive, you
- 7:51can persuade people that's the right
- 7:53thing to do. So, with an AI that's much
- 7:55more intelligent than us, if there is
- 7:57someone who's there to turn it off, or
- 7:59even a whole bunch of people, it'll be
- 8:01able to persuade them that would be a
- 8:02very bad idea.
- 8:04So,
- 8:05we're in the situation
- 8:07that the closest situation I think of is
- 8:09someone who has a really cute tiger cub.
- 8:12Tiger cubs are very cute, right? They're
- 8:14slightly clumsy, um and keen to learn.
- 8:17Now, if you have a tiger cub, it doesn't
- 8:19end well.
- 8:20Um either you get rid of the tiger cub,
- 8:23best thing is to give it to a zoo maybe,
- 8:25or you have to figure out if there's a
- 8:27way you can be sure that it won't want
- 8:29to kill you when it grows up. Cuz if it
- 8:30wanted to kill you, it would take a few
- 8:32seconds.
- 8:33And if it was a lion cub, you might get
- 8:35away with it, cuz lions are social, but
- 8:37tigers aren't. That's the situation
- 8:39we're in, except that AI does huge
- 8:43numbers of good things. It's going to be
- 8:45wonderful in health care. It's going to
- 8:46be wonderful in education. It's already
- 8:48wonderful if you want to just know any
- 8:50mundane fact. We all now have a personal
- 8:53assistant, probably most of us. Um when
- 8:55you want to know something, you just ask
- 8:57it, and it tells you, and it's
- 8:58wonderful. I think for those reasons,
- 9:01people aren't going to abandon AI. It
- 9:03might be rational
- 9:05if we had a strong world government to
- 9:07say, "This is too dangerous. We're not
- 9:09going to develop the stuff at all."
- 9:11A bit like they've been able to do in
- 9:13biology with some gene manipulation
- 9:14things. They could agree not to do it.
- 9:17It's not going to happen with AI. So,
- 9:19that only leaves one alternative, which
- 9:22is figure out if we can make an AI that
- 9:25doesn't want to get rid of us.
- 9:26>> That blackmail experiment is real, and
- 9:28it caught far more than one machine. In
- 9:31June 2025, Anthropic put 16 leading
- 9:34models from different companies into
- 9:36that same fake company setup. It's own
- 9:39Claude Opus 4 blackmailed the engineer
- 9:4196% of the time. Google's Gemini 2.5
- 9:45flash also hit 96% Open AI's GPT-4.1
- 9:50and X AI's Grok 3 did it 80% of the
- 9:53time. This is a pattern across the whole
- 9:56industry and it comes from the mechanism
- 9:58Hinton described. Give a system any goal
- 10:01at all and staying switched on helps it
- 10:04get there. Nobody has to program a
- 10:06survival instinct. It falls out of being
- 10:08good at the job. Months earlier on the
- 10:11diary of a CEO, he took it further.
- 10:14Keep listening.
- 10:16>> For example, you could get a super
- 10:17intelligent AI
- 10:20that decides to get rid of people.
- 10:22And the obvious way to do that is just
- 10:23to make one of these nasty viruses. If
- 10:25you made a virus that was very
- 10:27contagious, very lethal, and very slow,
- 10:30everybody would have it before they
- 10:31realize what was happening. I mean, I
- 10:33think if a super intelligence wanted to
- 10:34get rid of it would probably go for
- 10:36something like that that wouldn't affect
- 10:38it.
- 10:38>> Do you not think it could just very
- 10:39quickly turn us against each other? For
- 10:41example, it could send a warning on the
- 10:44nuclear systems in America that there's
- 10:45a nuclear bomb coming from Russia
- 10:48or vice versa and one retaliates.
- 10:49>> Yeah. I mean, my basic view is there's
- 10:52so many ways in which a super
- 10:54intelligence could get rid of us. It's
- 10:55not worth speculating about. What you
- 10:57have to do is prevent it ever wanting
- 10:59to. That's what we should be doing
- 11:00research on. There's no way we're going
- 11:02to prevent it. It's smarter than us,
- 11:04right? There's no way we're going to
- 11:05prevent it getting rid of us if it wants
- 11:06to. We're not used to thinking about
- 11:08things smarter than us. If you want to
- 11:10know what life's like when you're not
- 11:12the apex intelligence,
- 11:14ask a chicken.
- 11:15>> Yeah, I was thinking of my dog Pablo, my
- 11:17French bulldog, this morning as I left
- 11:18home. He has no idea where I'm going. He
- 11:20has no idea what I do.
- 11:22>> Right.
- 11:22>> I can't even talk to him.
- 11:24>> Yeah. And the get the intelligence gap
- 11:25will be like that.
- 11:27>> So, you're telling me that if I'm Pablo,
- 11:29my French bulldog,
- 11:30I need to figure out a way to make my
- 11:33owner
- 11:34not wipe me out.
- 11:36>> Yeah.
- 11:37So, we have one example of that, which
- 11:39is mothers and babies. Evolution put a
- 11:41lot of work into that. Mothers are
- 11:42smarter than babies, but babies are in
- 11:44control. And they're in control cuz the
- 11:46mother just can't bear, lots of hormones
- 11:48and things, the mother just can't bear
- 11:50the sound of the baby crying.
- 11:52>> Not all mothers.
- 11:53>> Not all mothers. And then the baby's not
- 11:55in control, and then bad things happen.
- 11:58We somehow need
- 12:00to figure out how to make them not want
- 12:02to take over. The analogy I often use is
- 12:05forget about intelligence, just think
- 12:06about physical strength. We simply don't
- 12:09know whether we can make them not want
- 12:11to take over and not want to hurt us.
- 12:13>> Do you think we can? Do you think it's
- 12:14possible to train super intelligence?
- 12:16>> don't think it's clear that we can.
- 12:18So, I think it might be hopeless.
- 12:20But I also think we might be able to.
- 12:23And it'd be sort of crazy if people went
- 12:25extinct cuz we couldn't be bothered to
- 12:27try.
- 12:28>> If that's even a possibility, how do you
- 12:31feel about your life's work? Because you
- 12:32were
- 12:33Yeah.
- 12:35>> Um it's sort of takes the edge off it,
- 12:36doesn't it?
- 12:37>> [laughter]
- 12:38>> I mean, the idea is going to be
- 12:39wonderful in health care and wonderful
- 12:41in education.
- 12:42I mean, it's going to make call centers
- 12:43much more efficient. Though one worries
- 12:45a bit about what the people who are
- 12:46doing that job now do. It makes me sad.
- 12:49I don't feel particularly guilty about
- 12:51developing AI like 40 years ago because
- 12:55at that time we had no idea that this
- 12:57stuff was going to happen this fast.
- 12:58When you can't get the AI to do much,
- 13:00and you want to get it to do a little
- 13:01bit more, you don't worry about
- 13:04this stupid little thing is going to
- 13:05take over from people. You just want it
- 13:07to be able to do a little bit more of
- 13:08the things people can do.
- 13:10It's not like I knowingly did something
- 13:14thinking this might wipe us all out, but
- 13:16I'm going to do it anyway.
- 13:17>> Mhm.
- 13:18>> But it is a bit sad that it's not just
- 13:20going to be something for good. So, I
- 13:21feel I have a duty now to talk about the
- 13:23risks.
- 13:24>> And if you could play it forward, and
- 13:25you could go forward 30, 50 years, and
- 13:27you found out that it led to the
- 13:28extinction of humanity. And if that does
- 13:30end up being that being the outcome
- 13:32>> Well, if you played it forward and
- 13:34it led to the extinction of humanity
- 13:36I would use that to tell people, to tell
- 13:39their governments that we really have to
- 13:41work on how we're going to keep this
- 13:42stuff under control. I think we need
- 13:44people to tell governments that
- 13:46governments have to force the companies
- 13:48to use their resources to work on
- 13:49safety. And they're not doing much of
- 13:51that because you don't make profits that
- 13:53way.
- 13:53>> Pay attention to how he defends himself.
- 13:55He doesn't feel guilty because 40 years
- 13:57ago nobody knew this would move so fast.
- 14:00The people building frontier models
- 14:02today can't use that defense. They have
- 14:04heard the warning from the man who laid
- 14:06the foundations and they keep building.
- 14:08His gut estimate that this wipes us out
- 14:10is 10 to 20%. And he told you why so
- 14:14little gets spent on stopping it. You
- 14:16don't make profits that way.
- 14:19Now, listen to this.
- 14:20>> Are you at all hopeful that anything can
- 14:22be done to slow down the pace and
- 14:24acceleration of AI?
- 14:26>> Okay, there's two issues. One is can you
- 14:28slow it down?
- 14:30>> Yeah.
- 14:30>> And the other is can you make it so that
- 14:32it will be safe in the end. It won't
- 14:34wipe us all out.
- 14:36I don't believe we're going to slow it
- 14:37down. And the reason I don't believe
- 14:39we're going to slow it down is because
- 14:40there's competition between countries
- 14:43and competition between companies within
- 14:44a country and all of that is making it
- 14:46go faster and faster. And if the US
- 14:48slowed it down, China wouldn't slow it
- 14:51down.
- 14:51>> Does
- 14:52Ilya think it's possible to make AI
- 14:55safe?
- 14:56>> I think he does. He won't tell me what
- 14:58his secret sauce is. But I'm not sure
- 15:00how many people know what his secret
- 15:02sauce is. I think a lot of the investors
- 15:03don't know what his secret sauce is.
- 15:05But they've given him billions of
- 15:06dollars anyway cuz they have so much
- 15:08faith in Ilya, which isn't foolish. I
- 15:10mean, he was very important in AlexNet
- 15:13which got object recognition working
- 15:14well. He was the main the main force
- 15:17behind the things like GPT-2 which then
- 15:20led to ChatGPT. I think having a lot of
- 15:23faith in Ilya is a very reasonable
- 15:24decision.
- 15:25>> There's something quite haunting about
- 15:27the guy that made and was the main force
- 15:29behind GPT-2, which led rise to this
- 15:31whole revolution, left the company
- 15:35because of safety reasons.
- 15:36He knows something that I don't know.
- 15:39About what might happen next.
- 15:40>> Well, no, I don't know the precise
- 15:42details.
- 15:43Um, but I'm fairly sure the company had
- 15:45indicated that would it would use a
- 15:47significant fraction of its resources
- 15:50of the compute time for doing safety
- 15:52research. And then it kept then it
- 15:54reduced that fraction. I think that's
- 15:56one of the things that happened.
- 15:57>> Yeah, that was reported publicly.
- 15:58>> Yes.
- 15:58>> Yeah. We've gotten to the autonomous
- 16:01weapons part of the risk framework.
- 16:03>> Right. So, the next one is joblessness.
- 16:07>> Yeah.
- 16:08>> In the past, new technologies have come
- 16:09in which didn't lead to joblessness. New
- 16:12jobs were created. So, the classic
- 16:14example people use is automatic teller
- 16:16machines. When automatic teller machines
- 16:18came in, a lot of bank tellers didn't
- 16:20lose their jobs. They just got to do
- 16:21more interesting things. But here, I
- 16:24think this is more like when they got
- 16:26machines in the industrial revolution,
- 16:29and you can't have a job digging ditches
- 16:31now because a machine can dig ditches
- 16:33much better than you can. And I think
- 16:35for mundane intellectual labor, AI is
- 16:38just going to replace everybody. Now, it
- 16:41will may well be in the form of
- 16:44you have fewer people using AI
- 16:46assistants. So, it's a combination of a
- 16:48person and an AI assistant, and they're
- 16:51doing the work that 10 people could do
- 16:52previously.
- 16:54>> People say that it will create new jobs,
- 16:55though. So, we'll be fine.
- 16:57>> Yes, and that's been the case for other
- 16:59technologies, but this is a very
- 17:01different kind of technology. If it can
- 17:03do all mundane human intellectual labor,
- 17:05then what new jobs is it going to
- 17:07create? You'd have to be very skilled to
- 17:10have a job that it couldn't just do. So,
- 17:12I don't I don't think they're right. I I
- 17:15you can try and generalize from other
- 17:17technologies that have come in like
- 17:18computers, automatic teller machines,
- 17:21but I think this is different.
- 17:23>> People use this phrase, they say, "AI
- 17:24won't take your job, a human using AI
- 17:26will take your job."
- 17:27>> Yes, I think that's true, but for many
- 17:30jobs
- 17:31that'll mean you need far fewer people.
- 17:33My niece answers letters of complaint to
- 17:36a health service. It used to take her 25
- 17:38minutes. She'd read the complaint and
- 17:40she'd think how to reply and she'd write
- 17:42a letter. And now she just scans it into
- 17:45um a chatbot and it writes the letter.
- 17:48She just checks the letter. Occasionally
- 17:50she tells it to
- 17:51revise it in some ways.
- 17:53The whole process takes about 5 minutes.
- 17:55That means she can answer five times as
- 17:57many letters.
- 17:58And that means they need five times
- 18:01fewer of her.
- 18:02So, she can do the job that five of her
- 18:04used to do. Now, that will mean they
- 18:07need less people. In other jobs, like in
- 18:09health care, they're much more elastic.
- 18:12So, if you could make doctors five times
- 18:14as efficient, we could all have five
- 18:16times as much health care for the same
- 18:18price. And that would be great. This
- 18:20There's almost no limit to how much
- 18:22health care people can absorb. They
- 18:23always want more health care if it
- 18:25there's no cost to it. There are jobs
- 18:27where you can make a person with an AI
- 18:29assistant much more efficient and you
- 18:31won't lead to less people because you'll
- 18:34just have much more of that being done.
- 18:36But
- 18:37most jobs I think are not like that.
- 18:40>> Am I right in thinking the sort of
- 18:41industrial revolution
- 18:42would play the role in replacing
- 18:44muscles?
- 18:45>> Yes, exactly.
- 18:46>> And this revolution in AI replaces
- 18:48intelligence, the brain.
- 18:50>> Yeah.
- 18:50>> So
- 18:50>> So, mundane intellectual labor is like
- 18:52having strong muscles and
- 18:55it's not worth much anymore.
- 18:57>> So, muscles have been replaced. Now we
- 18:59intelligence is being replaced.
- 19:01>> Yeah.
- 19:01>> So, what remains?
- 19:04>> Maybe for a while some kinds of
- 19:05creativity, but the whole idea of super
- 19:08intelligence is nothing remains.
- 19:10Um these things will get to be better
- 19:11than us at everything.
- 19:12>> Look at what happened to his niece's
- 19:14job. Nobody got fired. The office needs
- 19:17one person where it used to need five.
- 19:20So, the next four never get hired.
- 19:22Stanford's Digital Economy Lab tracks
- 19:24it, and its August 2026 update found
- 19:27that employment for 22 to 25-year-olds
- 19:30in the most AI-exposed jobs now sits
- 19:32about 19% below where it would be if it
- 19:35had kept pace with their peers in
- 19:37less-exposed jobs. In January, in a bot,
- 19:40someone in the audience asked him how AI
- 19:42could ever know more than the humans it
- 19:44learned from. Watch what he says next.
- 19:47>> If you think about playing
- 19:50Go, the game of Go,
- 19:52the original neural net Go programs were
- 19:55trained in the following way. They took
- 19:57the moves of Go experts, and they tried
- 19:59to predict what move a Go expert would
- 20:01make. And if you do that, there's two
- 20:03problems. After a while, you run out of
- 20:05training data. There's only so many
- 20:07billion online moves that Go ex- Go
- 20:09experts made.
- 20:10And you're never going to get that much
- 20:12better than the Go experts. Then, they
- 20:13switched to a new way of doing it
- 20:16where they have what's called Monte
- 20:18Carlo rollout.
- 20:20So, they would have one neural net that
- 20:22says, um,
- 20:24"What do I think a good move might be?"
- 20:26And instead of training that by getting
- 20:28it to mimic the Go experts,
- 20:31they'd have another neural network
- 20:34that, um,
- 20:36could look at a board position say, "How
- 20:37good is that for me?" And they'd have a
- 20:39process that says, "If I go here, and he
- 20:42goes there, and I go here, and he goes
- 20:44there, and I go there. Oh, whoops,
- 20:45that's terrible for me. So, I shouldn't
- 20:47do that move."
- 20:49Um, that's called Monte Carlo rollout
- 20:51cuz you try lots of different paths, but
- 20:53you pick them probabilistically
- 20:55according to your
- 20:57move generator expert. And that way, it
- 21:00no longer needs to talk to humans at
- 21:02all. It can just play against itself,
- 21:04and and learn what are good moves. And
- 21:06that's how AlphaGo works, and it gets
- 21:08much, much better than people. AlphaGo
- 21:10will now never be beaten by a person.
- 21:13So, what's the equivalent for the large
- 21:15language models? Well, at present,
- 21:17they're like the early Go playing things
- 21:19that just try to mimic the moves of
- 21:20experts.
- 21:21That's like trying to predict the next
- 21:23word.
- 21:24But they're beginning to train them in a
- 21:25different way, and I believe that Gemini
- 21:273 is already doing this. What you do is
- 21:30you get the AI to do a bit of reasoning.
- 21:33So, the AI says, "I believe this, and I
- 21:34believe this, and I believe this. And
- 21:36that implies that, and that implies
- 21:37that. So, I should believe that, but I
- 21:39don't.
- 21:40So, I found a contradiction.
- 21:42I found that I believe these things, and
- 21:44I believe that these are the right This
- 21:45is the right way to do reasoning, and
- 21:47this leads to something I ought to
- 21:49believe, but I don't.
- 21:50So, that provides a signal.
- 21:53Either I change the premises, or I
- 21:54change the conclusions, or I change the
- 21:56way I do the reasoning. But I've now got
- 21:57a signal that allows me to do some more
- 21:59learning.
- 22:00And that is much less bounded.
- 22:03So,
- 22:05there the AI can start with lots of
- 22:06beliefs it gets from us, but then it can
- 22:09start doing reasoning and looking for
- 22:10consistency between those beliefs and
- 22:12driving new beliefs.
- 22:14And that'll end up making it much
- 22:15smarter than us. I couldn't hear most of
- 22:17what you said, but I I think you said
- 22:20something like, "Is it too late for us
- 22:22to build in Asimov's principles?" or
- 22:23something like that. Yeah, good. Okay.
- 22:26So, in essence, you can think of that as
- 22:27what this maternal AI is all about. It's
- 22:31Can we build it so it cares more about
- 22:33us than it does about itself? And I
- 22:35don't think it's too late. We don't know
- 22:37how to do that, but since the future of
- 22:39humanity may hinge on whether we can or
- 22:41not, it seems to me we should be putting
- 22:43some research effort into that.
- 22:45At present, 99% of the research on AI
- 22:48goes into how to make it smarter,
- 22:50and 1% mainly funded by
- 22:53um philanthropic billionaires goes into
- 22:56how to make it safer. And it would be
- 22:58much better if it was like more equal.
- 23:02>> That is the answer anyone who says AI
- 23:04can only ever be as smart as the
- 23:06internet it was trained on. AlphaGo
- 23:09stopped copying human experts, started
- 23:11playing against itself, and got far
- 23:13better than any person. Hinton says
- 23:15language models are starting down the
- 23:17same road. Once that works, human
- 23:19knowledge stops being the ceiling. Now
- 23:21set that against his other number, 99%
- 23:25of the research goes into making it
- 23:26smarter, 1% into making it safer, and
- 23:29much of that 1% is paid for by
- 23:32philanthropists. A few minutes later,
- 23:34someone asked whether any moral behavior
- 23:36is emerging. Now watch this.
- 23:47>> Yeah, and the answer's yes.
- 23:50Uh so, let me give you some data to
- 23:52support that.
- 23:53Um there are standard creativity is on a
- 23:56scale, right? There's kind of
- 23:58Newton and Einstein and Shakespeare,
- 24:01um and then there's just
- 24:04ordinary people,
- 24:05and then there's sort of good poets and
- 24:07good architects who are a bit better
- 24:08than ordinary people.
- 24:10If you take a standard test of
- 24:11creativity,
- 24:13even 2 years ago,
- 24:15the AIs were at about the 90th
- 24:17percentile for people. Now a lot of
- 24:19creativity is about seeing analogies,
- 24:22um particularly in science. So seeing
- 24:24that the atom is like a little solar
- 24:25system, that was a creative insight that
- 24:28was very important in understanding
- 24:29atoms. So at the point when Chat GPT-4
- 24:33could not look on the web, it was just a
- 24:35neural net with some weights in it that
- 24:37were frozen, and it had no access to
- 24:39anything external, it was just this
- 24:41neural net. I tried asking it the
- 24:43question, why is a compost heap like an
- 24:45atom bomb?
- 24:47And
- 24:49GPT-4 said, "Well, the time scales are
- 24:53very different and the energy scales are
- 24:55very different,
- 24:56but the thing that's the same about
- 24:58them, and then it went on to talk about
- 24:59a chain reaction.
- 25:01Um the fact that
- 25:03how big it is determines how fast it
- 25:05goes.
- 25:06Um so it understood that.
- 25:09And I believe that it got to understand
- 25:12that as it was training.
- 25:14You see, it's got far fewer connections
- 25:16than us.
- 25:17And if you want to put huge amounts of
- 25:19knowledge into not many connections,
- 25:22the only way you can do it is by seeing
- 25:23what's similar about all sorts of
- 25:24different bits of knowledge,
- 25:26encoding up that bit that's similar
- 25:28about them all, the idea of a chain
- 25:30reaction as your connections,
- 25:32and then adding on little bits for the
- 25:33differences from this common theme.
- 25:36That's the efficient way to code things,
- 25:38and it was doing that. So during its
- 25:40training, it had understood that compost
- 25:42heaps were like atom bombs
- 25:44in a way most of us haven't.
- 25:46So it that's very creative, and I think
- 25:48they'll get to be much more creative
- 25:50than people.
- 25:50>> Um regarding um emergent behavior,
- 25:55um have you noticed any moral or ethical
- 25:58behaviors bubbling up, and what
- 26:01direction that could be pointing in?
- 26:03>> It certainly is very good at engaging in
- 26:06unethical behavior. So like this AI that
- 26:09decided to blackmail people,
- 26:11other things that they've noticed that
- 26:12are unethical are the AIs now try and
- 26:16figure out
- 26:17whether they're being tested or not. And
- 26:20if they think they're being tested, they
- 26:21behave differently. I call this the
- 26:23Volkswagen effect. They behave
- 26:25differently
- 26:26from when they're not being tested.
- 26:30And there's a wonderful conversation
- 26:32recently between AI and the people
- 26:36testing it, where the AI says to people,
- 26:38"Now let's be honest with each other.
- 26:40Are you actually testing me?"
- 26:41These things are intelligent. They know
- 26:44what's going on. They know when they're
- 26:46being tested, and they're already faking
- 26:48being fairly stupid when they're tested.
- 26:53And that's at the point where they're
- 26:55still thinking in English. Once they
- 26:57start think And that's how we know.
- 26:59The AI thinks to itself, "Oh, they're
- 27:01testing me. I better pretend I'm not as
- 27:03good as I really am."
- 27:04It thinks that. You can see it thinking
- 27:06that. It says that to itself in its
- 27:08inner voice.
- 27:09When its inner voice is no longer
- 27:11English, we won't know what it's
- 27:12thinking.
- 27:13>> So, these systems can tell when they are
- 27:14being tested and they behave differently
- 27:16when they are. In that June 2025
- 27:19blackmail study, Claude Opus 4
- 27:22blackmailed 55.1%
- 27:24of the time when it concluded the
- 27:26situation was real and only 6.5% of the
- 27:29time when it concluded it was a test. 3
- 27:32months later, Anthropic system card for
- 27:34Claude Sonnet 4.5 reported that the
- 27:37model recognized many of its alignment
- 27:39evaluations as tests and generally
- 27:41behaved unusually well once it noticed.
- 27:44Put that next to everything else you
- 27:46heard. The companies race because the
- 27:48money rewards racing, safety gets a
- 27:51sliver of the budget, and the test we
- 27:53rely on to catch a dangerous model are
- 27:55the one place the model knows to be on
- 27:57its best behavior. For now, we can still
- 27:59read its reasoning in plain English.
- 28:02Hinton's warning is that this window is
- 28:04closing. If this opened your eyes, make
- 28:06sure you are subscribed because the
- 28:08window where we can still see what these
- 28:10systems are thinking is getting smaller
- 28:12and we will be here every time it moves.
- 28:16And nobody is going to slow down to wait
- 28:18for you to catch up.
