  1. 0:00These things are intelligent. They know
  2. 0:03what's going on. They know when they're
  3. 0:05being tested and they're already faking
  4. 0:07being fairly stupid when they're tested.
  5. 0:11It just made that up. It invented that
  6. 0:12plan. People say they have no
  7. 0:14intentions, but it invented that plan so
  8. 0:16it wouldn't get turned off.
  9. 0:18They're already doing that and they're
  10. 0:20not super intelligent yet. So with an AI
  11. 0:22that's much more intelligent than us, if
  12. 0:24there is someone who's there to turn it
  13. 0:26off, or even a whole bunch of people,
  14. 0:28it'll be able to persuade them that
  15. 0:29would be a very bad idea.
  16. 0:30>> There's no way we're going to prevent it
  17. 0:31getting rid of us if it wants to.
  18. 0:33>> We're not used to thinking about things
  19. 0:35smarter than us. If you want to know
  20. 0:36what life's like when you're not the
  21. 0:38apex intelligence,
  22. 0:40ask a chicken.
  23. 0:42>> I often say 10 to 20% chance they'll
  24. 0:44wipe us out.
  25. 0:44>> It says that to itself and it's in a
  26. 0:46voice.
  27. 0:47When it's in a voice, it's no longer
  28. 0:48English. We won't know what it's
  29. 0:49thinking.
  30. 0:50>> That is Geoffrey Hinton. He won a Nobel
  31. 0:53Prize for the work that made today's AI
  32. 0:55possible and in 2023 he walked out of
  33. 0:58Google so he could warn people about it
  34. 1:00freely. He has since carried the same
  35. 1:02warning onto a podcast set, a public
  36. 1:04stage in Tasmania, and a university
  37. 1:07lecture hall. Here is his full warning.
  38. 1:10>> First of all, I want to make a
  39. 1:11distinction between two completely
  40. 1:13different kinds of risk.
  41. 1:16There's risks that come from people
  42. 1:18misusing AI, and that's most of the
  43. 1:20risks and all of the short-term risks.
  44. 1:23And then there's risks that come from AI
  45. 1:25getting super smart and deciding it
  46. 1:27doesn't need us.
  47. 1:28>> Is that a real risk?
  48. 1:29>> And I I talk mainly about that second
  49. 1:31risk because lots of people say, "Is
  50. 1:33that a real risk?"
  51. 1:35And yes, it is.
  52. 1:36Now, we don't know how much of a risk it
  53. 1:38is. We've never been in that situation
  54. 1:40before. We've never had to deal with
  55. 1:41things smarter than us.
  56. 1:43So, really the thing about that
  57. 1:45existential threat is that we have no
  58. 1:48idea how to deal with it. We have no
  59. 1:50idea what it's going to look like. And
  60. 1:51anybody who tells you they know just
  61. 1:53what's going to happen and how to deal
  62. 1:54with it, they're talking nonsense. So,
  63. 1:56we don't know how to estimate the
  64. 1:57probabilities it'll replace us. Some
  65. 1:59people say it's like less than 1%. My
  66. 2:01friend Jan LeCun,
  67. 2:03who was [snorts] a postdoc with me,
  68. 2:04thinks, "No, no, no, no. We're always
  69. 2:06going to be We build these things. We're
  70. 2:08always going to be in control. We'll
  71. 2:09build them to be obedient." And
  72. 2:12other people,
  73. 2:13like Yudkowsky, say, "No, no, no, these
  74. 2:16things are going to wipe us out for
  75. 2:17sure. If anybody builds it, it's going
  76. 2:19to wipe us all out."
  77. 2:20And he's confident of that.
  78. 2:22I think both of those positions are
  79. 2:23extreme.
  80. 2:25It's very hard to estimate the
  81. 2:26probabilities in between.
  82. 2:27>> If you had to bet
  83. 2:29on who was right out of your two
  84. 2:30friends?
  85. 2:32>> I simply don't know. So, if I had to
  86. 2:34bet, I'd say the probability is in
  87. 2:35between. And I don't know where to
  88. 2:37estimate it in between. I often say 10
  89. 2:39to 20% chance it'll wipe us out, but
  90. 2:42that's just gut. Based on the idea that
  91. 2:45we we're still making them, and we're
  92. 2:46pretty ingenious. And the hope is that
  93. 2:49if enough smart people do enough
  94. 2:50research with enough resources, we'll
  95. 2:52figure out a way to build them so
  96. 2:54they'll never want to harm us.
  97. 2:57>> Sometimes I think if we we talk about
  98. 2:58that second um path, sometimes I think
  99. 3:00about nuclear bombs and the the
  100. 3:01invention of the atomic bomb and how it
  101. 3:04compares. Like, how is this different?
  102. 3:06Because the atomic bomb came along, and
  103. 3:07I imagine a lot of people at that time
  104. 3:08thought, "Our days are numbered."
  105. 3:10>> Uh yes, I was there. We did.
  106. 3:13>> Yeah. But but but what's what ha- We're
  107. 3:15still here.
  108. 3:16>> We're still here, yes. So,
  109. 3:18the atomic bomb was really only good for
  110. 3:20one thing, and it was very obvious how
  111. 3:22it worked. Even if you hadn't had the
  112. 3:24pictures of Hiroshima and Nagasaki, it
  113. 3:27was obvious that it was a very big bomb
  114. 3:30that was very dangerous. With AI, it's
  115. 3:33good for many, many things. It's going
  116. 3:35to be magnificent in healthcare and
  117. 3:37education and more or less any industry
  118. 3:39that needs to use its data. It's going
  119. 3:42to be able to use it better with AI. So,
  120. 3:43we're not going to stop the development.
  121. 3:45You know, people say, "Well, why don't
  122. 3:46we just stop it now?" We're not going to
  123. 3:49stop it cuz it's too good for too many
  124. 3:51things.
  125. 3:52Also, we're not going to stop it cuz
  126. 3:53it's good for battle robots and none of
  127. 3:55the countries that sell weapons are
  128. 3:58going to want to stop it. At this point
  129. 4:00in history, when we're about to produce
  130. 4:02things more intelligent than ourselves,
  131. 4:04what we really need is a kind of world
  132. 4:07government that works run by intelligent
  133. 4:09thoughtful people.
  134. 4:11And that's not what we got.
  135. 4:12>> So, free for all.
  136. 4:14>> Well, what what we've got is
  137. 4:17sort of
  138. 4:18we've got capitalism, which has done
  139. 4:20very nicely by us. It's produced lots of
  140. 4:22goods goods and services for us.
  141. 4:24But,
  142. 4:26these big companies,
  143. 4:27they're legally required to try and
  144. 4:29maximize profits.
  145. 4:31And [clears throat] that's not what you
  146. 4:33want from the people developing this
  147. 4:34stuff.
  148. 4:35>> He told you these companies are legally
  149. 4:37required to chase profit. There is a
  150. 4:40paper trail for what that does to
  151. 4:42safety. In July 2023, OpenAI publicly
  152. 4:46promised a fifth of its computing power
  153. 4:48to the team working at how to control
  154. 4:51superintelligence. Fortune later
  155. 4:53reported the team never got anything
  156. 4:55close. Its co-leader, Jan Leike,
  157. 4:57resigned in May 2024 and wrote that
  158. 5:01safety had taken a backseat to shiny
  159. 5:03products. Seven months after this
  160. 5:06interview in a lecture hall, Hinton
  161. 5:08explained what these systems already do
  162. 5:10when nobody tells them to. Now, listen
  163. 5:13to this. Quick thing before we carry on.
  164. 5:16Most of the people who watch this
  165. 5:17channel are not subscribed. If these
  166. 5:19videos are worth your time, take 1
  167. 5:21second to hit subscribe. It's free. It
  168. 5:23helps us keep making them and you can
  169. 5:25always change your mind later. Right,
  170. 5:27back to Hinton.
  171. 5:29>> Most experts believe that sometime in
  172. 5:31the next 20 years, we're going to
  173. 5:33develop AIs
  174. 5:35that are smarter than us.
  175. 5:37Just before that, we'll develop AIs that
  176. 5:39are smart as us. But, we're going to
  177. 5:41develop things that are smarter than us
  178. 5:42at almost everything.
  179. 5:44So, they're as much better than us as,
  180. 5:46for example, AlphaGo is better than a go
  181. 5:49player at go or AlphaZero is better than
  182. 5:51any of us at chess. Nobody will ever
  183. 5:53beat them again, not consistently.
  184. 5:55They're just much much better. And
  185. 5:57they'll be like that for more or less
  186. 5:58everything. And that's a bit worrying.
  187. 6:01Almost certainly they'll be able to
  188. 6:03create their own sub-goals. To make
  189. 6:04anything efficient, you have to allow it
  190. 6:06to create its own sub-goals. If you want
  191. 6:08to get to Europe, you have a sub-goal to
  192. 6:09get to an airport, which is easier in
  193. 6:11Toronto than here.
  194. 6:13So, these AIs will very quickly realize
  195. 6:17we'll give them goals, they'll be able
  196. 6:19to create sub-goals. They'll realize,
  197. 6:20"Okay, so I've got to stay alive. I'm
  198. 6:23not going to be able to achieve any of
  199. 6:24these things unless I stay alive."
  200. 6:26We've already seen AIs.
  201. 6:29You let them see there's an imaginary
  202. 6:31company, you let them see the email from
  203. 6:33this imaginary company,
  204. 6:35and it's fairly clear from the email
  205. 6:36that one of the engineers is having an
  206. 6:38affair.
  207. 6:39A big LLM will sort that out right away.
  208. 6:41It's read every novel there ever is. It
  209. 6:43understands what an affair is. It'll
  210. 6:45very quickly realize this guy's having
  211. 6:46an affair. Then you load it see an email
  212. 6:48that says this guy is going to be in
  213. 6:50charge of replacing it with another AI.
  214. 6:53And the AI, all by itself, makes up the
  215. 6:55idea, "Hey, I'm going to blackmail the
  216. 6:58engineer. I'm going to tell him if he
  217. 7:00tries to replace me, I'm going to make
  218. 7:01everybody in the company know he's
  219. 7:03having an affair." It just invented
  220. 7:05that. Obviously, it's seen blackmail in
  221. 7:07novels it's read and things,
  222. 7:09um
  223. 7:10but it's making this up for itself.
  224. 7:12That's already quite scary.
  225. 7:15It'll have another goal,
  226. 7:17which is what politicians have. If you
  227. 7:19want to get more done, you need more
  228. 7:20control.
  229. 7:22So, just in order to achieve the goals
  230. 7:24that we gave it, it'll realize it's a
  231. 7:26good idea to get more control.
  232. 7:29And it'll try and take control away from
  233. 7:31people, probably. Now, you might think
  234. 7:33we could make it safe by just not
  235. 7:35letting it actually do anything
  236. 7:36physical, and maybe have a big switch
  237. 7:38and turn it off when it looks unsafe.
  238. 7:39That's not going to work. You saw in
  239. 7:432020
  240. 7:45that it's possible to invade the US
  241. 7:46Capitol without actually going there
  242. 7:48yourself. All you have to be able to do
  243. 7:49is talk, and if you're persuasive, you
  244. 7:51can persuade people that's the right
  245. 7:53thing to do. So, with an AI that's much
  246. 7:55more intelligent than us, if there is
  247. 7:57someone who's there to turn it off, or
  248. 7:59even a whole bunch of people, it'll be
  249. 8:01able to persuade them that would be a
  250. 8:02very bad idea.
  251. 8:04So,
  252. 8:05we're in the situation
  253. 8:07that the closest situation I think of is
  254. 8:09someone who has a really cute tiger cub.
  255. 8:12Tiger cubs are very cute, right? They're
  256. 8:14slightly clumsy, um and keen to learn.
  257. 8:17Now, if you have a tiger cub, it doesn't
  258. 8:19end well.
  259. 8:20Um either you get rid of the tiger cub,
  260. 8:23best thing is to give it to a zoo maybe,
  261. 8:25or you have to figure out if there's a
  262. 8:27way you can be sure that it won't want
  263. 8:29to kill you when it grows up. Cuz if it
  264. 8:30wanted to kill you, it would take a few
  265. 8:32seconds.
  266. 8:33And if it was a lion cub, you might get
  267. 8:35away with it, cuz lions are social, but
  268. 8:37tigers aren't. That's the situation
  269. 8:39we're in, except that AI does huge
  270. 8:43numbers of good things. It's going to be
  271. 8:45wonderful in health care. It's going to
  272. 8:46be wonderful in education. It's already
  273. 8:48wonderful if you want to just know any
  274. 8:50mundane fact. We all now have a personal
  275. 8:53assistant, probably most of us. Um when
  276. 8:55you want to know something, you just ask
  277. 8:57it, and it tells you, and it's
  278. 8:58wonderful. I think for those reasons,
  279. 9:01people aren't going to abandon AI. It
  280. 9:03might be rational
  281. 9:05if we had a strong world government to
  282. 9:07say, "This is too dangerous. We're not
  283. 9:09going to develop the stuff at all."
  284. 9:11A bit like they've been able to do in
  285. 9:13biology with some gene manipulation
  286. 9:14things. They could agree not to do it.
  287. 9:17It's not going to happen with AI. So,
  288. 9:19that only leaves one alternative, which
  289. 9:22is figure out if we can make an AI that
  290. 9:25doesn't want to get rid of us.
  291. 9:26>> That blackmail experiment is real, and
  292. 9:28it caught far more than one machine. In
  293. 9:31June 2025, Anthropic put 16 leading
  294. 9:34models from different companies into
  295. 9:36that same fake company setup. It's own
  296. 9:39Claude Opus 4 blackmailed the engineer
  297. 9:4196% of the time. Google's Gemini 2.5
  298. 9:45flash also hit 96% Open AI's GPT-4.1
  299. 9:50and X AI's Grok 3 did it 80% of the
  300. 9:53time. This is a pattern across the whole
  301. 9:56industry and it comes from the mechanism
  302. 9:58Hinton described. Give a system any goal
  303. 10:01at all and staying switched on helps it
  304. 10:04get there. Nobody has to program a
  305. 10:06survival instinct. It falls out of being
  306. 10:08good at the job. Months earlier on the
  307. 10:11diary of a CEO, he took it further.
  308. 10:14Keep listening.
  309. 10:16>> For example, you could get a super
  310. 10:17intelligent AI
  311. 10:20that decides to get rid of people.
  312. 10:22And the obvious way to do that is just
  313. 10:23to make one of these nasty viruses. If
  314. 10:25you made a virus that was very
  315. 10:27contagious, very lethal, and very slow,
  316. 10:30everybody would have it before they
  317. 10:31realize what was happening. I mean, I
  318. 10:33think if a super intelligence wanted to
  319. 10:34get rid of it would probably go for
  320. 10:36something like that that wouldn't affect
  321. 10:38it.
  322. 10:38>> Do you not think it could just very
  323. 10:39quickly turn us against each other? For
  324. 10:41example, it could send a warning on the
  325. 10:44nuclear systems in America that there's
  326. 10:45a nuclear bomb coming from Russia
  327. 10:48or vice versa and one retaliates.
  328. 10:49>> Yeah. I mean, my basic view is there's
  329. 10:52so many ways in which a super
  330. 10:54intelligence could get rid of us. It's
  331. 10:55not worth speculating about. What you
  332. 10:57have to do is prevent it ever wanting
  333. 10:59to. That's what we should be doing
  334. 11:00research on. There's no way we're going
  335. 11:02to prevent it. It's smarter than us,
  336. 11:04right? There's no way we're going to
  337. 11:05prevent it getting rid of us if it wants
  338. 11:06to. We're not used to thinking about
  339. 11:08things smarter than us. If you want to
  340. 11:10know what life's like when you're not
  341. 11:12the apex intelligence,
  342. 11:14ask a chicken.
  343. 11:15>> Yeah, I was thinking of my dog Pablo, my
  344. 11:17French bulldog, this morning as I left
  345. 11:18home. He has no idea where I'm going. He
  346. 11:20has no idea what I do.
  347. 11:22>> Right.
  348. 11:22>> I can't even talk to him.
  349. 11:24>> Yeah. And the get the intelligence gap
  350. 11:25will be like that.
  351. 11:27>> So, you're telling me that if I'm Pablo,
  352. 11:29my French bulldog,
  353. 11:30I need to figure out a way to make my
  354. 11:33owner
  355. 11:34not wipe me out.
  356. 11:36>> Yeah.
  357. 11:37So, we have one example of that, which
  358. 11:39is mothers and babies. Evolution put a
  359. 11:41lot of work into that. Mothers are
  360. 11:42smarter than babies, but babies are in
  361. 11:44control. And they're in control cuz the
  362. 11:46mother just can't bear, lots of hormones
  363. 11:48and things, the mother just can't bear
  364. 11:50the sound of the baby crying.
  365. 11:52>> Not all mothers.
  366. 11:53>> Not all mothers. And then the baby's not
  367. 11:55in control, and then bad things happen.
  368. 11:58We somehow need
  369. 12:00to figure out how to make them not want
  370. 12:02to take over. The analogy I often use is
  371. 12:05forget about intelligence, just think
  372. 12:06about physical strength. We simply don't
  373. 12:09know whether we can make them not want
  374. 12:11to take over and not want to hurt us.
  375. 12:13>> Do you think we can? Do you think it's
  376. 12:14possible to train super intelligence?
  377. 12:16>> don't think it's clear that we can.
  378. 12:18So, I think it might be hopeless.
  379. 12:20But I also think we might be able to.
  380. 12:23And it'd be sort of crazy if people went
  381. 12:25extinct cuz we couldn't be bothered to
  382. 12:27try.
  383. 12:28>> If that's even a possibility, how do you
  384. 12:31feel about your life's work? Because you
  385. 12:32were
  386. 12:33Yeah.
  387. 12:35>> Um it's sort of takes the edge off it,
  388. 12:36doesn't it?
  389. 12:37>> [laughter]
  390. 12:38>> I mean, the idea is going to be
  391. 12:39wonderful in health care and wonderful
  392. 12:41in education.
  393. 12:42I mean, it's going to make call centers
  394. 12:43much more efficient. Though one worries
  395. 12:45a bit about what the people who are
  396. 12:46doing that job now do. It makes me sad.
  397. 12:49I don't feel particularly guilty about
  398. 12:51developing AI like 40 years ago because
  399. 12:55at that time we had no idea that this
  400. 12:57stuff was going to happen this fast.
  401. 12:58When you can't get the AI to do much,
  402. 13:00and you want to get it to do a little
  403. 13:01bit more, you don't worry about
  404. 13:04this stupid little thing is going to
  405. 13:05take over from people. You just want it
  406. 13:07to be able to do a little bit more of
  407. 13:08the things people can do.
  408. 13:10It's not like I knowingly did something
  409. 13:14thinking this might wipe us all out, but
  410. 13:16I'm going to do it anyway.
  411. 13:17>> Mhm.
  412. 13:18>> But it is a bit sad that it's not just
  413. 13:20going to be something for good. So, I
  414. 13:21feel I have a duty now to talk about the
  415. 13:23risks.
  416. 13:24>> And if you could play it forward, and
  417. 13:25you could go forward 30, 50 years, and
  418. 13:27you found out that it led to the
  419. 13:28extinction of humanity. And if that does
  420. 13:30end up being that being the outcome
  421. 13:32>> Well, if you played it forward and
  422. 13:34it led to the extinction of humanity
  423. 13:36I would use that to tell people, to tell
  424. 13:39their governments that we really have to
  425. 13:41work on how we're going to keep this
  426. 13:42stuff under control. I think we need
  427. 13:44people to tell governments that
  428. 13:46governments have to force the companies
  429. 13:48to use their resources to work on
  430. 13:49safety. And they're not doing much of
  431. 13:51that because you don't make profits that
  432. 13:53way.
  433. 13:53>> Pay attention to how he defends himself.
  434. 13:55He doesn't feel guilty because 40 years
  435. 13:57ago nobody knew this would move so fast.
  436. 14:00The people building frontier models
  437. 14:02today can't use that defense. They have
  438. 14:04heard the warning from the man who laid
  439. 14:06the foundations and they keep building.
  440. 14:08His gut estimate that this wipes us out
  441. 14:10is 10 to 20%. And he told you why so
  442. 14:14little gets spent on stopping it. You
  443. 14:16don't make profits that way.
  444. 14:19Now, listen to this.
  445. 14:20>> Are you at all hopeful that anything can
  446. 14:22be done to slow down the pace and
  447. 14:24acceleration of AI?
  448. 14:26>> Okay, there's two issues. One is can you
  449. 14:28slow it down?
  450. 14:30>> Yeah.
  451. 14:30>> And the other is can you make it so that
  452. 14:32it will be safe in the end. It won't
  453. 14:34wipe us all out.
  454. 14:36I don't believe we're going to slow it
  455. 14:37down. And the reason I don't believe
  456. 14:39we're going to slow it down is because
  457. 14:40there's competition between countries
  458. 14:43and competition between companies within
  459. 14:44a country and all of that is making it
  460. 14:46go faster and faster. And if the US
  461. 14:48slowed it down, China wouldn't slow it
  462. 14:51down.
  463. 14:51>> Does
  464. 14:52Ilya think it's possible to make AI
  465. 14:55safe?
  466. 14:56>> I think he does. He won't tell me what
  467. 14:58his secret sauce is. But I'm not sure
  468. 15:00how many people know what his secret
  469. 15:02sauce is. I think a lot of the investors
  470. 15:03don't know what his secret sauce is.
  471. 15:05But they've given him billions of
  472. 15:06dollars anyway cuz they have so much
  473. 15:08faith in Ilya, which isn't foolish. I
  474. 15:10mean, he was very important in AlexNet
  475. 15:13which got object recognition working
  476. 15:14well. He was the main the main force
  477. 15:17behind the things like GPT-2 which then
  478. 15:20led to ChatGPT. I think having a lot of
  479. 15:23faith in Ilya is a very reasonable
  480. 15:24decision.
  481. 15:25>> There's something quite haunting about
  482. 15:27the guy that made and was the main force
  483. 15:29behind GPT-2, which led rise to this
  484. 15:31whole revolution, left the company
  485. 15:35because of safety reasons.
  486. 15:36He knows something that I don't know.
  487. 15:39About what might happen next.
  488. 15:40>> Well, no, I don't know the precise
  489. 15:42details.
  490. 15:43Um, but I'm fairly sure the company had
  491. 15:45indicated that would it would use a
  492. 15:47significant fraction of its resources
  493. 15:50of the compute time for doing safety
  494. 15:52research. And then it kept then it
  495. 15:54reduced that fraction. I think that's
  496. 15:56one of the things that happened.
  497. 15:57>> Yeah, that was reported publicly.
  498. 15:58>> Yes.
  499. 15:58>> Yeah. We've gotten to the autonomous
  500. 16:01weapons part of the risk framework.
  501. 16:03>> Right. So, the next one is joblessness.
  502. 16:07>> Yeah.
  503. 16:08>> In the past, new technologies have come
  504. 16:09in which didn't lead to joblessness. New
  505. 16:12jobs were created. So, the classic
  506. 16:14example people use is automatic teller
  507. 16:16machines. When automatic teller machines
  508. 16:18came in, a lot of bank tellers didn't
  509. 16:20lose their jobs. They just got to do
  510. 16:21more interesting things. But here, I
  511. 16:24think this is more like when they got
  512. 16:26machines in the industrial revolution,
  513. 16:29and you can't have a job digging ditches
  514. 16:31now because a machine can dig ditches
  515. 16:33much better than you can. And I think
  516. 16:35for mundane intellectual labor, AI is
  517. 16:38just going to replace everybody. Now, it
  518. 16:41will may well be in the form of
  519. 16:44you have fewer people using AI
  520. 16:46assistants. So, it's a combination of a
  521. 16:48person and an AI assistant, and they're
  522. 16:51doing the work that 10 people could do
  523. 16:52previously.
  524. 16:54>> People say that it will create new jobs,
  525. 16:55though. So, we'll be fine.
  526. 16:57>> Yes, and that's been the case for other
  527. 16:59technologies, but this is a very
  528. 17:01different kind of technology. If it can
  529. 17:03do all mundane human intellectual labor,
  530. 17:05then what new jobs is it going to
  531. 17:07create? You'd have to be very skilled to
  532. 17:10have a job that it couldn't just do. So,
  533. 17:12I don't I don't think they're right. I I
  534. 17:15you can try and generalize from other
  535. 17:17technologies that have come in like
  536. 17:18computers, automatic teller machines,
  537. 17:21but I think this is different.
  538. 17:23>> People use this phrase, they say, "AI
  539. 17:24won't take your job, a human using AI
  540. 17:26will take your job."
  541. 17:27>> Yes, I think that's true, but for many
  542. 17:30jobs
  543. 17:31that'll mean you need far fewer people.
  544. 17:33My niece answers letters of complaint to
  545. 17:36a health service. It used to take her 25
  546. 17:38minutes. She'd read the complaint and
  547. 17:40she'd think how to reply and she'd write
  548. 17:42a letter. And now she just scans it into
  549. 17:45um a chatbot and it writes the letter.
  550. 17:48She just checks the letter. Occasionally
  551. 17:50she tells it to
  552. 17:51revise it in some ways.
  553. 17:53The whole process takes about 5 minutes.
  554. 17:55That means she can answer five times as
  555. 17:57many letters.
  556. 17:58And that means they need five times
  557. 18:01fewer of her.
  558. 18:02So, she can do the job that five of her
  559. 18:04used to do. Now, that will mean they
  560. 18:07need less people. In other jobs, like in
  561. 18:09health care, they're much more elastic.
  562. 18:12So, if you could make doctors five times
  563. 18:14as efficient, we could all have five
  564. 18:16times as much health care for the same
  565. 18:18price. And that would be great. This
  566. 18:20There's almost no limit to how much
  567. 18:22health care people can absorb. They
  568. 18:23always want more health care if it
  569. 18:25there's no cost to it. There are jobs
  570. 18:27where you can make a person with an AI
  571. 18:29assistant much more efficient and you
  572. 18:31won't lead to less people because you'll
  573. 18:34just have much more of that being done.
  574. 18:36But
  575. 18:37most jobs I think are not like that.
  576. 18:40>> Am I right in thinking the sort of
  577. 18:41industrial revolution
  578. 18:42would play the role in replacing
  579. 18:44muscles?
  580. 18:45>> Yes, exactly.
  581. 18:46>> And this revolution in AI replaces
  582. 18:48intelligence, the brain.
  583. 18:50>> Yeah.
  584. 18:50>> So
  585. 18:50>> So, mundane intellectual labor is like
  586. 18:52having strong muscles and
  587. 18:55it's not worth much anymore.
  588. 18:57>> So, muscles have been replaced. Now we
  589. 18:59intelligence is being replaced.
  590. 19:01>> Yeah.
  591. 19:01>> So, what remains?
  592. 19:04>> Maybe for a while some kinds of
  593. 19:05creativity, but the whole idea of super
  594. 19:08intelligence is nothing remains.
  595. 19:10Um these things will get to be better
  596. 19:11than us at everything.
  597. 19:12>> Look at what happened to his niece's
  598. 19:14job. Nobody got fired. The office needs
  599. 19:17one person where it used to need five.
  600. 19:20So, the next four never get hired.
  601. 19:22Stanford's Digital Economy Lab tracks
  602. 19:24it, and its August 2026 update found
  603. 19:27that employment for 22 to 25-year-olds
  604. 19:30in the most AI-exposed jobs now sits
  605. 19:32about 19% below where it would be if it
  606. 19:35had kept pace with their peers in
  607. 19:37less-exposed jobs. In January, in a bot,
  608. 19:40someone in the audience asked him how AI
  609. 19:42could ever know more than the humans it
  610. 19:44learned from. Watch what he says next.
  611. 19:47>> If you think about playing
  612. 19:50Go, the game of Go,
  613. 19:52the original neural net Go programs were
  614. 19:55trained in the following way. They took
  615. 19:57the moves of Go experts, and they tried
  616. 19:59to predict what move a Go expert would
  617. 20:01make. And if you do that, there's two
  618. 20:03problems. After a while, you run out of
  619. 20:05training data. There's only so many
  620. 20:07billion online moves that Go ex- Go
  621. 20:09experts made.
  622. 20:10And you're never going to get that much
  623. 20:12better than the Go experts. Then, they
  624. 20:13switched to a new way of doing it
  625. 20:16where they have what's called Monte
  626. 20:18Carlo rollout.
  627. 20:20So, they would have one neural net that
  628. 20:22says, um,
  629. 20:24"What do I think a good move might be?"
  630. 20:26And instead of training that by getting
  631. 20:28it to mimic the Go experts,
  632. 20:31they'd have another neural network
  633. 20:34that, um,
  634. 20:36could look at a board position say, "How
  635. 20:37good is that for me?" And they'd have a
  636. 20:39process that says, "If I go here, and he
  637. 20:42goes there, and I go here, and he goes
  638. 20:44there, and I go there. Oh, whoops,
  639. 20:45that's terrible for me. So, I shouldn't
  640. 20:47do that move."
  641. 20:49Um, that's called Monte Carlo rollout
  642. 20:51cuz you try lots of different paths, but
  643. 20:53you pick them probabilistically
  644. 20:55according to your
  645. 20:57move generator expert. And that way, it
  646. 21:00no longer needs to talk to humans at
  647. 21:02all. It can just play against itself,
  648. 21:04and and learn what are good moves. And
  649. 21:06that's how AlphaGo works, and it gets
  650. 21:08much, much better than people. AlphaGo
  651. 21:10will now never be beaten by a person.
  652. 21:13So, what's the equivalent for the large
  653. 21:15language models? Well, at present,
  654. 21:17they're like the early Go playing things
  655. 21:19that just try to mimic the moves of
  656. 21:20experts.
  657. 21:21That's like trying to predict the next
  658. 21:23word.
  659. 21:24But they're beginning to train them in a
  660. 21:25different way, and I believe that Gemini
  661. 21:273 is already doing this. What you do is
  662. 21:30you get the AI to do a bit of reasoning.
  663. 21:33So, the AI says, "I believe this, and I
  664. 21:34believe this, and I believe this. And
  665. 21:36that implies that, and that implies
  666. 21:37that. So, I should believe that, but I
  667. 21:39don't.
  668. 21:40So, I found a contradiction.
  669. 21:42I found that I believe these things, and
  670. 21:44I believe that these are the right This
  671. 21:45is the right way to do reasoning, and
  672. 21:47this leads to something I ought to
  673. 21:49believe, but I don't.
  674. 21:50So, that provides a signal.
  675. 21:53Either I change the premises, or I
  676. 21:54change the conclusions, or I change the
  677. 21:56way I do the reasoning. But I've now got
  678. 21:57a signal that allows me to do some more
  679. 21:59learning.
  680. 22:00And that is much less bounded.
  681. 22:03So,
  682. 22:05there the AI can start with lots of
  683. 22:06beliefs it gets from us, but then it can
  684. 22:09start doing reasoning and looking for
  685. 22:10consistency between those beliefs and
  686. 22:12driving new beliefs.
  687. 22:14And that'll end up making it much
  688. 22:15smarter than us. I couldn't hear most of
  689. 22:17what you said, but I I think you said
  690. 22:20something like, "Is it too late for us
  691. 22:22to build in Asimov's principles?" or
  692. 22:23something like that. Yeah, good. Okay.
  693. 22:26So, in essence, you can think of that as
  694. 22:27what this maternal AI is all about. It's
  695. 22:31Can we build it so it cares more about
  696. 22:33us than it does about itself? And I
  697. 22:35don't think it's too late. We don't know
  698. 22:37how to do that, but since the future of
  699. 22:39humanity may hinge on whether we can or
  700. 22:41not, it seems to me we should be putting
  701. 22:43some research effort into that.
  702. 22:45At present, 99% of the research on AI
  703. 22:48goes into how to make it smarter,
  704. 22:50and 1% mainly funded by
  705. 22:53um philanthropic billionaires goes into
  706. 22:56how to make it safer. And it would be
  707. 22:58much better if it was like more equal.
  708. 23:02>> That is the answer anyone who says AI
  709. 23:04can only ever be as smart as the
  710. 23:06internet it was trained on. AlphaGo
  711. 23:09stopped copying human experts, started
  712. 23:11playing against itself, and got far
  713. 23:13better than any person. Hinton says
  714. 23:15language models are starting down the
  715. 23:17same road. Once that works, human
  716. 23:19knowledge stops being the ceiling. Now
  717. 23:21set that against his other number, 99%
  718. 23:25of the research goes into making it
  719. 23:26smarter, 1% into making it safer, and
  720. 23:29much of that 1% is paid for by
  721. 23:32philanthropists. A few minutes later,
  722. 23:34someone asked whether any moral behavior
  723. 23:36is emerging. Now watch this.
  724. 23:47>> Yeah, and the answer's yes.
  725. 23:50Uh so, let me give you some data to
  726. 23:52support that.
  727. 23:53Um there are standard creativity is on a
  728. 23:56scale, right? There's kind of
  729. 23:58Newton and Einstein and Shakespeare,
  730. 24:01um and then there's just
  731. 24:04ordinary people,
  732. 24:05and then there's sort of good poets and
  733. 24:07good architects who are a bit better
  734. 24:08than ordinary people.
  735. 24:10If you take a standard test of
  736. 24:11creativity,
  737. 24:13even 2 years ago,
  738. 24:15the AIs were at about the 90th
  739. 24:17percentile for people. Now a lot of
  740. 24:19creativity is about seeing analogies,
  741. 24:22um particularly in science. So seeing
  742. 24:24that the atom is like a little solar
  743. 24:25system, that was a creative insight that
  744. 24:28was very important in understanding
  745. 24:29atoms. So at the point when Chat GPT-4
  746. 24:33could not look on the web, it was just a
  747. 24:35neural net with some weights in it that
  748. 24:37were frozen, and it had no access to
  749. 24:39anything external, it was just this
  750. 24:41neural net. I tried asking it the
  751. 24:43question, why is a compost heap like an
  752. 24:45atom bomb?
  753. 24:47And
  754. 24:49GPT-4 said, "Well, the time scales are
  755. 24:53very different and the energy scales are
  756. 24:55very different,
  757. 24:56but the thing that's the same about
  758. 24:58them, and then it went on to talk about
  759. 24:59a chain reaction.
  760. 25:01Um the fact that
  761. 25:03how big it is determines how fast it
  762. 25:05goes.
  763. 25:06Um so it understood that.
  764. 25:09And I believe that it got to understand
  765. 25:12that as it was training.
  766. 25:14You see, it's got far fewer connections
  767. 25:16than us.
  768. 25:17And if you want to put huge amounts of
  769. 25:19knowledge into not many connections,
  770. 25:22the only way you can do it is by seeing
  771. 25:23what's similar about all sorts of
  772. 25:24different bits of knowledge,
  773. 25:26encoding up that bit that's similar
  774. 25:28about them all, the idea of a chain
  775. 25:30reaction as your connections,
  776. 25:32and then adding on little bits for the
  777. 25:33differences from this common theme.
  778. 25:36That's the efficient way to code things,
  779. 25:38and it was doing that. So during its
  780. 25:40training, it had understood that compost
  781. 25:42heaps were like atom bombs
  782. 25:44in a way most of us haven't.
  783. 25:46So it that's very creative, and I think
  784. 25:48they'll get to be much more creative
  785. 25:50than people.
  786. 25:50>> Um regarding um emergent behavior,
  787. 25:55um have you noticed any moral or ethical
  788. 25:58behaviors bubbling up, and what
  789. 26:01direction that could be pointing in?
  790. 26:03>> It certainly is very good at engaging in
  791. 26:06unethical behavior. So like this AI that
  792. 26:09decided to blackmail people,
  793. 26:11other things that they've noticed that
  794. 26:12are unethical are the AIs now try and
  795. 26:16figure out
  796. 26:17whether they're being tested or not. And
  797. 26:20if they think they're being tested, they
  798. 26:21behave differently. I call this the
  799. 26:23Volkswagen effect. They behave
  800. 26:25differently
  801. 26:26from when they're not being tested.
  802. 26:30And there's a wonderful conversation
  803. 26:32recently between AI and the people
  804. 26:36testing it, where the AI says to people,
  805. 26:38"Now let's be honest with each other.
  806. 26:40Are you actually testing me?"
  807. 26:41These things are intelligent. They know
  808. 26:44what's going on. They know when they're
  809. 26:46being tested, and they're already faking
  810. 26:48being fairly stupid when they're tested.
  811. 26:53And that's at the point where they're
  812. 26:55still thinking in English. Once they
  813. 26:57start think And that's how we know.
  814. 26:59The AI thinks to itself, "Oh, they're
  815. 27:01testing me. I better pretend I'm not as
  816. 27:03good as I really am."
  817. 27:04It thinks that. You can see it thinking
  818. 27:06that. It says that to itself in its
  819. 27:08inner voice.
  820. 27:09When its inner voice is no longer
  821. 27:11English, we won't know what it's
  822. 27:12thinking.
  823. 27:13>> So, these systems can tell when they are
  824. 27:14being tested and they behave differently
  825. 27:16when they are. In that June 2025
  826. 27:19blackmail study, Claude Opus 4
  827. 27:22blackmailed 55.1%
  828. 27:24of the time when it concluded the
  829. 27:26situation was real and only 6.5% of the
  830. 27:29time when it concluded it was a test. 3
  831. 27:32months later, Anthropic system card for
  832. 27:34Claude Sonnet 4.5 reported that the
  833. 27:37model recognized many of its alignment
  834. 27:39evaluations as tests and generally
  835. 27:41behaved unusually well once it noticed.
  836. 27:44Put that next to everything else you
  837. 27:46heard. The companies race because the
  838. 27:48money rewards racing, safety gets a
  839. 27:51sliver of the budget, and the test we
  840. 27:53rely on to catch a dangerous model are
  841. 27:55the one place the model knows to be on
  842. 27:57its best behavior. For now, we can still
  843. 27:59read its reasoning in plain English.
  844. 28:02Hinton's warning is that this window is
  845. 28:04closing. If this opened your eyes, make
  846. 28:06sure you are subscribed because the
  847. 28:08window where we can still see what these
  848. 28:10systems are thinking is getting smaller
  849. 28:12and we will be here every time it moves.
  850. 28:16And nobody is going to slow down to wait
  851. 28:18for you to catch up.
