Jeff Hawkins is asking questions about locations of mobiles here kzbin.info/www/bejne/ppCug6Z8YtOWgLM that I think could eventually be answered by the future GPT3… Here is my hypothesis: I was thinking of this last week : Brain makes maps of the environment. But I was wondering how it managed mobile objects. How it worked to know where it is. It's location. And then I remembered that when I was a kid, my mom would always ask me this question when I had lost something: When did you use it the last time? The question when. And I would try to remember what happened the last days, all the chronological events with a context linked to the object. And then I would remember where it could be. I'm amazed to consider that finally, the brain has a chronological map of events and their context, remembering every sequence and is able to navigate in this chronological map of events. And every object is there, the brain has all these objects identified and painted in every events, and keep all these pictures (I say picture, but it can be linked to any senses) chronologically and can navigate in this chronological mapping, like if the events were layers it can access. Soooooo if the events are like layers that can be accessed chronologically (or you can make jumps, but knowing where it stands in the chronology), could a future GPT3 do pattern recognitions on sequences. Could it learn sequences of patterns and then make predictions?

You might want to ask in the Q&A 00:29:55.989,00:29:58.989 Yitz: asked there, sorry about that 00:30:05.713,00:30:08.713 Trevor Hill-Hand: I've been starting to think of game design as the art of showing a system through a carefully chosen lens. 00:33:00.624,00:33:03.624 Jonathan Blow: kzbin.info/www/bejne/hXi2ln-JorR0grc 00:33:21.615,00:33:24.615 Yitz: ooh, I've really been enjoying watching that game develop 00:33:28.546,00:33:31.546 Greg: I would like to play miegakure and I hope the developer has something playable soon 00:42:07.124,00:42:10.124 Yitz: Godel strikes again! 00:48:39.058,00:48:42.058 Yitz: he has said roughly as much in a recent blogg post 00:52:24.623,00:52:27.623 David Manheim: ...and the ways that specific laws get passed then circumvented tends not to eliminate the underlying pattern. 00:53:50.314,00:53:53.314 David Manheim: (The obvious way to fix most of this is for Google Play, Apples, etc. to limit the amount any one player can spend on a game's IAP. But that's against their interest in collecting a percentage, so it's probably not a real possibility.) 00:54:10.097,00:54:13.097 James Friesen: thanks for the answer jon! 00:57:17.494,00:57:20.494 Yitz: ethics-it's tricky! 01:05:19.367,01:05:22.367 Isaac Leonard: en.wikipedia.org/wiki/Beresheet 01:06:03.843,01:06:06.843 David Manheim: Isaac: What is that link supposed to relate to? 01:06:33.370,01:06:36.370 Isaac Leonard: Landing an archive on the moon. 01:06:49.651,01:06:52.651 Isaac Leonard: > The spacecraft carried a "time capsule" containing over 30 million pages of data, including a full copy of the English-language Wikipedia, the Wearable Rosetta disc,... 01:07:07.192,01:07:10.192 Isaac Leonard: (I think this is what he was referring to.) 01:07:52.817,01:07:55.817 Yitz: oh cool, my work on Wikipedia is on the Moon then! 01:10:28.767,01:10:31.767 Yitz: that's fine, as an artist myself I totally get it :) 01:11:11.803,01:11:14.803 Haru Glory: I love the longform answers :) 01:11:25.791,01:11:28.791 Trevor Hill-Hand: I see a lot of good questions, so my vote goes towards "as short as reasonable for the question, but no shorter" 01:12:46.766,01:12:49.766 Yitz: I think the current work of Nathalie Lawhead (creator of EVERYTHING IS GOING TO BE OKAY, etc.) is really intriguing in that respect 01:13:43.380,01:13:46.380 Yitz: en.wikipedia.org/wiki/Langton%27s_ant is my favorite cellular automata 01:15:12.170,01:15:15.170 mako yass: Jon should probably read the questions and decide for himself what would be interesting to answer, at least a few? He knows more than we do about what he has to say. 01:18:55.900,01:18:58.900 Yitz: would someone mind typing out the name of this book? I didn't catch the name 01:19:35.559,01:19:38.559 Mo Zhu: Baumol's cost disease 01:19:43.816,01:19:46.816 Yitz: thanks :) 01:19:53.067,01:19:56.067 Cameron Mulhern: I'm guessing it's this: www.goodreads.com/book/show/13594020-the-cost-disease 01:20:57.379,01:21:00.379 Caleb Rudnick: Thank you! 01:22:45.796,01:22:48.796 Greg: I think people are tempted to interpret Braid in that way because of the specific and rather jarring, way in which the atomic bomb reference happens in the game 01:22:59.372,01:23:02.372 Yitz: the best interpretations are those that leave you with even more questions than you had before, imo 01:25:36.084,01:25:39.084 Maxwell Joslyn: A good read about the technical aspects/challenges of decentralized systems: medium.com/swlh/a-unified-theory-of-decentralization-151d6f39e38 01:30:35.471,01:30:38.471 Yitz: I think you'd enjoy the altgame space; although much of the art in that scene isn't technically super impressive, there is an incredible amount of care and uniqueness put into it 01:32:44.765,01:32:47.765 Angelique Po: Thanks for answering. That's about what I was thinking re: AI-gen art.

To clarify, I kind of assume that a) similar opportunities are likely to appear in future, b) rational-ish circles might have advantage in detecting such opportunities the same way they had some advantage with Bitcoin/pandemic, c) opportunity window might be way shorter than the early days of cheap Bitcoin, so it might be important to stay alert. 00:33:28.735,00:33:31.735 David Manheim: Marcin: the problem is that the rationalist community now controls billions of dollars, easily. 00:34:00.977,00:34:03.977 David Manheim: So the window for noticing would need to be a subset of the community. 00:35:07.045,00:35:10.045 Joshua Fox: At the end we will meet and socialize in these rooms.

Does the example of extremely high positive valence in the experience of becoming a parent somehow contradict the whole 'replicators vs consciousness' notion?
3 жыл бұрын
I don't see why. Evolution recruited very high-valence states in order to motivate reproduction. But it also recruited extremely negative states as well, which certainly go against the interests/values of consciousness. If evolution could have gotten away with a less euphoric feeling of being a parent while still having the same motivating/reinforcing quality, being a parent wouldn't feel that great. In the long run, if we don't rationally steer evolution in the direction of serving consciousness, there is no guarantee we will feel good about anything.

Good talk, GPT-3 should be the fire alarm that wakes everyone up. AI safety research is the main field that is going to make a change long term.

Considering the ant analogy w.r.t. the hydro dam: even if we could explain it in ant-language, the fact that they have to move their whole society means they probably just won't do a damn thing: see climate change. also: Good example of the fire alarm, never thought about it that way.

You mentioned you have experimented with GPT-3. I would love to do so myself, but I was not able to find GPT-3's model and weights available. Is it only available for certain people? Or you have to register somewhere?

They have an invite-only beta you can apply for (see the "Join the waitlist" link openai.com/blog/openai-api/) but they will change it to a pricing model soon seen here www.reddit.com/r/GPT3/comments/ikorgs

27:54 Not only is our planet not new, but it is thought that it took well over a billion years after life started before it got lucky and created the innovation of sex, and the specialization provided by mitochondria, and then more than another billion years for multicellular Eukyrotic life to evolve. Presumably our luck could have been better (but it could equally be that our timeline was unusually luckily.) 31:56 If I lived to be a trillion years old, I'd probably decide that it is likely I will want to live to be a quadrillion years old and therefore I'd want to start capturing the energy of stars (and do what with it? A better approach might be to somehow prevent fusion from starting inside nebulas until it is deliberately triggered, thus creating "battery stars" to be activated trillions of years later). But in a younger universe like ours, perhaps there is little urge to actually do this. To the extent there is an urge, Dyson spheres could be hard to notice once completed, and our tools of observation are limited. 42:40 All evidence points to the simulation hypothesis being false. If it is true, the simulation must devote a lot of processing power to deceiving us with evidence that it is false, and therefore the simulation was designed for us specifically. But then, why deceive us with evidence and yet allow people to believe in it anyway? medium.com/big-picture/sorry-youre-not-in-the-matrix-4a321eed8384 cosmosmagazine.com/physics/physicists-find-we-re-not-living-in-a-computer-simulation

17:05 The formation of intelligent life could be extremely unlikely, putting a Great Filter behind us, but that doesn't mean there isn't another one in front of us. Keep this in mind before deciding that a Paperclip Maximizer (or happy face maximizer, or happy-acting otherwise-useless hominid maximizer) is unlikely. Or, if civilizations rarely make them because it's such an obvious trap, we must still be careful to avoid the trap. Also note that an organization that makes a dangerous Paperclip Maximizer necessarily does so by accident, and so may tend not design it in such a way that it expands beyond its home planet, or it may eventually become self-defeating, which would explain why we wouldn't notice it. Another version of great filter is where any biological civilization that expands will eventually colonize a planet ruled by a paranoid dictator who decides that all other colonies are a potential threat and decides to kill them all off with biological weapons, sent on probes, before they can attack. Synthetic civilizations could face an analogous problem in a form that is unpredictable (if they are intelligent enough, they might develop decision theory to the point where they detect that expansion is inherently unsafe and must not be done; of course it is not possible to know whether this scenario is plausible without ourselves being as advanced as they are). 24:40 Err... huh? what? See Stargate Universe Season 2 (fourth quarter) for a depressing scenario that could be imagined in which it would be extremely unwise to broadcast our presence to the rest of the galaxy. In all cases we must remember that destruction is generally easier than creation, in our universe anyhow. Note also that in recent years we ourselves have reduced our output of intelligent-looking radio signals (digital signals, as they become more efficient, tend to both get weaker, and more focused/directed, and resemble noise to a greater and greater extent), implying it is hard to find signals from advanced civilizations unless they broadcast intentionally.
