WEBVTT - NotebookLM Podcast: David Deusch, Understanding, and AI 0:00:21.153 --> 0:00:23.613 Okay, so get this. Today we're going to tackle something 0:00:23.613 --> 0:00:28.623 pretty wild. Can I actually understand things? Understand? Yeah. And 0:00:28.623 --> 0:00:31.413 I don't mean, like, follow simple instructions. I'm talking about 0:00:31.413 --> 0:00:36.393 grasping concepts, making connections. You know, like actually thinking. 0:00:36.423 --> 0:00:39.063 Ah, the big question. And you found some fascinating stuff 0:00:39.063 --> 0:00:43.293 on this, especially connecting it to David Deutsch's constructor theory. Right. Right. 0:00:43.293 --> 0:00:46.653 We're diving deep into my excerpts on AI and consciousness. 0:00:46.653 --> 0:00:50.073 But through that constructor theory lens, which honestly is a 0:00:50.073 --> 0:00:52.413 bit of a mind bender on its own, you know, 0:00:52.443 --> 0:00:54.873 I can imagine I knew a little about Deutsch's work 0:00:54.873 --> 0:00:58.293 on quantum computation before. Pretty wild stuff. But how does 0:00:58.293 --> 0:01:01.263 that connect to something as complex as understanding? It seems 0:01:01.263 --> 0:01:02.913 like a whole different ball game. 0:01:02.913 --> 0:01:06.813 It's a fascinating link, actually. Your materials really highlight how 0:01:06.813 --> 0:01:09.753 we might test for understanding in AI. So one thing 0:01:09.783 --> 0:01:12.813 to ask cannot understand, but a whole other challenge to 0:01:12.843 --> 0:01:15.603 figure out how to measure that, especially without relying on 0:01:15.633 --> 0:01:19.353 things like feelings or personal experiences the way we do 0:01:19.353 --> 0:01:20.073 with people. 0:01:20.073 --> 0:01:22.133 That's what's so intriguing to me, is like trying to 0:01:22.133 --> 0:01:24.923 figure out if an alien species understands us, even if 0:01:24.923 --> 0:01:27.353 we don't speak the same language. And that's where Deutsch 0:01:27.353 --> 0:01:28.283 comes in. Exactly. 0:01:28.283 --> 0:01:31.313 Instead of focusing on how things happen step by step, 0:01:31.313 --> 0:01:34.223 constructor theory looks at what's actually possible in the universe. 0:01:34.223 --> 0:01:37.163 It's like a cosmic rule book that says time travel 0:01:37.163 --> 0:01:41.573 not allowed. Creating a black hole. Go for it. It's 0:01:41.573 --> 0:01:43.703 about possibilities, not just mechanisms. 0:01:43.733 --> 0:01:46.073 Okay, so it's less about how and more about can 0:01:46.103 --> 0:01:48.233 it be done at all? Right, right. 0:01:48.353 --> 0:01:52.973 And Deutsch argues that this focus on what's possible could 0:01:52.973 --> 0:01:56.753 be the key to understanding how information works in the universe, 0:01:56.783 --> 0:01:59.993 including the kind of information processing that might lead to 0:02:00.023 --> 0:02:01.643 understanding in AI. 0:02:01.823 --> 0:02:04.433 Interesting. So are you saying that instead of trying to 0:02:04.463 --> 0:02:07.703 measure consciousness or feelings in AI, we should be looking 0:02:07.703 --> 0:02:10.253 at what it can actually do with information? 0:02:10.283 --> 0:02:13.073 Exactly. And the conversation you've shared lays out some really 0:02:13.073 --> 0:02:16.613 interesting ways to test that, focusing on four key things 0:02:16.613 --> 0:02:23.243 analogical reasoning, counterfactual scenarios. Conceptual combination and error detection. 0:02:23.243 --> 0:02:25.733 Four types of tests. Okay, I'm taking notes here. So 0:02:25.733 --> 0:02:27.353 give me an example. What would one of these tests 0:02:27.383 --> 0:02:27.953 look like? 0:02:27.983 --> 0:02:29.993 Well remember that part where they asked the AI to 0:02:30.023 --> 0:02:34.103 compare how human memory works to how computers store data? Oh, right. 0:02:34.103 --> 0:02:36.533 Right. Trying to find the common thread between two things 0:02:36.533 --> 0:02:38.423 that seem totally different on the surface. 0:02:38.453 --> 0:02:41.993 Exactly. That's analogical reasoning. It's a core part of how 0:02:41.993 --> 0:02:46.223 humans learn. We relate new information to things we already know. 0:02:46.253 --> 0:02:48.743 Makes sense. It's like, how is a tree trunk like 0:02:48.743 --> 0:02:53.183 a human bone, structurally? What about those what if scenarios? 0:02:53.183 --> 0:02:55.343 The counterfactuals, those always mess me up. 0:02:55.373 --> 0:02:59.183 Ah yes, those are fun because they really force the 0:02:59.183 --> 0:03:02.093 AI to think about cause and effect, to imagine different 0:03:02.123 --> 0:03:05.513 outcomes based on different starting conditions. Like how would human 0:03:05.513 --> 0:03:09.743 biology be different if gravity were twice as strong? Wow. 0:03:09.773 --> 0:03:12.083 Okay, I see what you mean. You're not just testing 0:03:12.083 --> 0:03:13.913 what it knows, but how well it can apply that 0:03:13.913 --> 0:03:16.943 knowledge to a totally hypothetical situation. 0:03:16.973 --> 0:03:20.423 Precisely. It's about understanding the relationships between things, not just 0:03:20.423 --> 0:03:21.893 memorizing facts. That's a good. 0:03:21.893 --> 0:03:25.073 One. Okay, so we've got analogies, counterfactuals. What were the 0:03:25.073 --> 0:03:25.313 other two? 0:03:25.343 --> 0:03:30.263 Again conceptual combination and error detection. Combination is where things 0:03:30.263 --> 0:03:34.493 get really creative. They ask the AI to imagine, for example, 0:03:34.523 --> 0:03:38.543 a transportation system that combines drones with ride sharing, drones. 0:03:38.543 --> 0:03:41.543 And ride sharing. That's oddly specific, but I get it. 0:03:41.543 --> 0:03:44.363 So it's like, could an AI invent the next Uber? 0:03:44.363 --> 0:03:45.833 But with flying cars. 0:03:45.833 --> 0:03:48.473 It's not just about rearranging words or images, it's about 0:03:48.473 --> 0:03:52.373 understanding underlying principles and then using those to imagine something 0:03:52.403 --> 0:03:53.003 totally new. 0:03:53.033 --> 0:03:55.103 Okay, yeah, that's a whole other level. And that requires 0:03:55.103 --> 0:03:58.703 some serious understanding, not just pattern recognition. So what about 0:03:58.703 --> 0:04:00.893 that last one, error detection? That one might. 0:04:00.893 --> 0:04:05.303 Seem less flashy, but it's crucial for true understanding. It's 0:04:05.303 --> 0:04:10.553 the ability to spot inconsistencies, logical fallacies, biases in information 0:04:10.553 --> 0:04:11.213 that kind of thing. 0:04:11.243 --> 0:04:14.033 Oh, like being able to spot fake news or a 0:04:14.033 --> 0:04:15.113 really bad argument. 0:04:15.143 --> 0:04:18.263 Exactly. Critical thinking is a key part of understanding and 0:04:18.263 --> 0:04:20.423 it's something we're still trying to figure out how to 0:04:20.453 --> 0:04:22.493 properly assess in AI. 0:04:22.523 --> 0:04:24.713 So we've got these tests, these ways to kind of 0:04:24.743 --> 0:04:28.373 poke and prod at an AI's understanding. But even if 0:04:28.373 --> 0:04:32.123 it passes with flying colors, is it really understanding things 0:04:32.123 --> 0:04:34.493 the way we do, or is it just a really, 0:04:34.493 --> 0:04:35.393 really good mimic. 0:04:35.423 --> 0:04:37.763 That cuts to the heart of it, doesn't it? And 0:04:37.763 --> 0:04:41.963 your excerpts really dive into that, exploring this potential understanding 0:04:41.963 --> 0:04:45.323 gap between what I can do and what might still 0:04:45.323 --> 0:04:45.923 be missing. 0:04:45.923 --> 0:04:49.223 Right. Like, is there something special about human understanding? They 0:04:49.223 --> 0:04:49.583 even bring. 0:04:49.583 --> 0:04:53.303 Up consciousness, asking if our own subjective experience, that feeling 0:04:53.303 --> 0:04:56.273 of being me inside our heads, adds something unique. 0:04:56.303 --> 0:04:58.133 Okay, so let's talk about that for a second, because 0:04:58.133 --> 0:05:00.683 the whole consciousness thing always seems to come up in 0:05:00.683 --> 0:05:05.693 these AI discussions. Is it really about like our feelings 0:05:05.693 --> 0:05:09.263 and sensations being some kind of special ingredient in how 0:05:09.263 --> 0:05:10.733 we process information? 0:05:11.153 --> 0:05:13.973 It's a compelling thought, right? We don't experience the world 0:05:13.973 --> 0:05:17.543 like computers do. Our emotions, memories, even our physical senses. 0:05:17.543 --> 0:05:20.853 They all influence how we understand things. Even a simple 0:05:20.853 --> 0:05:24.243 color like red. It might trigger very different feelings or 0:05:24.243 --> 0:05:27.003 memories for you than it does for me. Okay, yeah. 0:05:27.003 --> 0:05:29.133 I get that. It's like red might make me think 0:05:29.133 --> 0:05:31.263 of strawberries, but you might think of like a stop 0:05:31.263 --> 0:05:33.963 sign or something. Totally different associations, same color. 0:05:33.963 --> 0:05:37.563 And those associations can then shape our understanding of other things, 0:05:37.563 --> 0:05:40.923 maybe even how we interpret a painting or a warning 0:05:40.923 --> 0:05:42.663 sign or a piece of music. 0:05:42.663 --> 0:05:46.773 But couldn't you argue that those emotional responses, even our senses, 0:05:46.773 --> 0:05:49.833 they're all just data points for our brains to process? Like, 0:05:49.833 --> 0:05:53.553 maybe consciousness is just this really, really complex algorithm running 0:05:53.553 --> 0:05:57.513 in the background, and we experience it as feelings and senses. 0:05:57.513 --> 0:06:00.303 That's the million dollar question. And the conversation you shared 0:06:00.333 --> 0:06:04.773 offers up a really interesting possibility. What if consciousness is, 0:06:04.773 --> 0:06:07.473 in a way, an evolutionary hack? 0:06:07.473 --> 0:06:10.353 An evolutionary hack. Okay, now you're just messing with me. 0:06:10.383 --> 0:06:11.943 What's that even mean? Think about it. 0:06:11.973 --> 0:06:14.793 What if this sense we have of being conscious of 0:06:14.793 --> 0:06:18.233 being a self inside our heads is less about representing 0:06:18.233 --> 0:06:22.073 some objective reality and more about giving us a survival advantage. 0:06:22.103 --> 0:06:24.473 So you're saying our brains are basically running on, like, 0:06:24.503 --> 0:06:26.513 cleverly designed glitches? 0:06:26.543 --> 0:06:30.233 In a way, the conversation you shared links consciousness to 0:06:30.263 --> 0:06:33.683 ideas like blame and praise, even free will. Wait. 0:06:33.713 --> 0:06:36.803 Free will as in like whether we actually have control 0:06:36.803 --> 0:06:38.183 over our choices. Right. 0:06:38.183 --> 0:06:40.283 If we believe we have free will, if we think 0:06:40.283 --> 0:06:43.823 we're responsible for our own actions, we're more likely to 0:06:43.853 --> 0:06:48.233 say follow social norms, work together, build societies. Yeah, even 0:06:48.233 --> 0:06:51.293 if it's all an illusion, that illusion might be what 0:06:51.293 --> 0:06:53.363 allows us to function as a species. 0:06:53.363 --> 0:06:56.123 That's kind of a mind blowing concept. So are we 0:06:56.123 --> 0:06:59.723 supposed to build AI that also believes in free will? 0:06:59.753 --> 0:07:03.113 That's where things get interesting. Yeah. If consciousness is primarily 0:07:03.113 --> 0:07:06.563 about function, about giving us an edge, then maybe I 0:07:06.593 --> 0:07:09.653 could achieve similar things without having the exact same kind 0:07:09.683 --> 0:07:11.003 of consciousness as us. 0:07:11.033 --> 0:07:13.433 Okay, but then what would that even look like? AI 0:07:13.463 --> 0:07:15.143 with its own version of consciousness. 0:07:15.143 --> 0:07:17.773 We can hardly imagine, but it would probably be based 0:07:17.773 --> 0:07:20.353 on what's useful for its survival and growth, which might 0:07:20.353 --> 0:07:21.583 be totally different from ours. 0:07:21.613 --> 0:07:24.823 Okay, you officially blown my mind. But before we disappear 0:07:24.853 --> 0:07:28.003 completely down the consciousness rabbit hole, let's loop back to 0:07:28.033 --> 0:07:31.573 those levels of understanding you mentioned earlier. Functional and creative. 0:07:31.603 --> 0:07:35.113 Didn't the I in these excerpts admit that it's kind 0:07:35.113 --> 0:07:36.913 of stuck at the functional level? 0:07:36.913 --> 0:07:39.943 It did. Remember how we talked about using a smartphone 0:07:39.943 --> 0:07:42.523 without needing to understand how to build one? Yeah, that's 0:07:42.523 --> 0:07:46.063 a good example of functional understanding. It's about applying knowledge, 0:07:46.063 --> 0:07:49.543 following the rules to get things done. And the AI 0:07:49.543 --> 0:07:54.523 in your excerpts demonstrates that constantly pulling up information, making connections, 0:07:54.523 --> 0:07:56.173 even writing like a human. 0:07:56.173 --> 0:07:58.093 But it hasn't won any Nobel Prizes yet. 0:07:58.243 --> 0:08:01.573 Exactly. That's where creative understanding comes in. It's about generating 0:08:01.603 --> 0:08:05.773 truly new insights, making connections no one has made before. 0:08:05.803 --> 0:08:08.233 Pushing the boundaries of knowledge in a way that leads 0:08:08.233 --> 0:08:09.253 to breakthroughs. 0:08:09.283 --> 0:08:12.163 Okay, I see the difference. Functional is like following a recipe. 0:08:12.193 --> 0:08:15.363 Creative is like inventing a whole new Cuisine. 0:08:15.393 --> 0:08:20.043 Precisely. But the eye does make an interesting point. A 0:08:20.043 --> 0:08:23.763 lot of Nobel prizes aren't given for some huge paradigm shift, 0:08:23.763 --> 0:08:28.383 some earth shattering discovery. Many are for insightful observations, for 0:08:28.383 --> 0:08:32.823 cleverly designed experiments, for spotting patterns that others have missed 0:08:32.823 --> 0:08:35.343 progress through incremental steps. 0:08:35.373 --> 0:08:38.553 So you're saying that I, even without that flash of 0:08:38.553 --> 0:08:42.333 aha that we associate with human creativity, could still push 0:08:42.333 --> 0:08:45.783 scientific knowledge forward just by analyzing massive amounts of data 0:08:45.783 --> 0:08:47.193 and making those connections? 0:08:47.223 --> 0:08:49.413 Exactly. And here's where the kind of data we're talking 0:08:49.413 --> 0:08:52.713 about becomes really important. The I even mentions that it's 0:08:52.713 --> 0:08:56.493 limitations in creative understanding might come from the limitations of 0:08:56.493 --> 0:08:59.313 its training data. It's like giving a chef a pantry 0:08:59.313 --> 0:09:01.443 with only a handful of ingredients. They can only be 0:09:01.443 --> 0:09:02.853 so creative with what they've got. 0:09:02.883 --> 0:09:06.153 But what if we give AI a pantry the size 0:09:06.153 --> 0:09:09.093 of the entire internet, or even bigger data sets that 0:09:09.093 --> 0:09:12.033 we haven't even imagined yet? Could that be the key 0:09:12.033 --> 0:09:14.753 to unlocking some next level creative potential. 0:09:14.783 --> 0:09:18.113 Now you're getting it. Imagine an AI that can sift 0:09:18.113 --> 0:09:21.923 through all that information, find patterns and connections across every 0:09:21.923 --> 0:09:24.863 field of study, every area of human knowledge. 0:09:24.893 --> 0:09:27.023 If you like having a team of the world's smartest 0:09:27.023 --> 0:09:30.323 researchers working around the clock. But wouldn't that be a 0:09:30.323 --> 0:09:31.853 little bit intimidating? It could. 0:09:31.853 --> 0:09:34.463 Be. Or maybe it's the key to unlocking our own potential. 0:09:34.493 --> 0:09:37.283 You know, imagine having access to all those insights, all 0:09:37.283 --> 0:09:40.673 those connections that I might uncover. It could completely revolutionize 0:09:40.673 --> 0:09:46.043 how we approach science, art, problem solving, everything, really. 0:09:46.043 --> 0:09:49.073 It's like we're on the verge of something truly transformative. 0:09:49.103 --> 0:09:52.643 But all this talk about AI's potential, it makes you 0:09:52.673 --> 0:09:56.183 wonder about our own limits as humans. If I can 0:09:56.183 --> 0:09:59.243 tap into these massive data sets and make connections that 0:09:59.243 --> 0:10:03.533 we miss, does that mean our understanding is like fundamentally 0:10:03.533 --> 0:10:06.803 limited by our biology, by our brains? 0:10:06.833 --> 0:10:09.353 It's a humbling thought, isn't it? We like to think 0:10:09.353 --> 0:10:11.423 we're at the top of the intelligence pyramid, but maybe 0:10:11.453 --> 0:10:13.433 we're just scratching the surface of what's possible. 0:10:13.453 --> 0:10:16.273 Maybe it's like we've been playing the game of understanding 0:10:16.273 --> 0:10:18.553 on easy mode, and now AI is about to crank 0:10:18.583 --> 0:10:20.683 up the difficulty level. But, you know, it's really interesting 0:10:20.713 --> 0:10:23.923 to me thinking about AI in this way. It makes 0:10:23.923 --> 0:10:26.713 you question your own thought processes. Like those aha moments. 0:10:26.713 --> 0:10:29.143 We always talk about those flashes of insight, right? 0:10:29.173 --> 0:10:29.893 What are those. 0:10:29.923 --> 0:10:34.153 Really? Exactly. If I can achieve these incredible feats of 0:10:34.153 --> 0:10:39.193 information processing, maybe our own intuition, our genius, it's not 0:10:39.193 --> 0:10:40.723 as magical as we like to think. 0:10:40.753 --> 0:10:43.603 It makes you wonder, doesn't it? What if those aha 0:10:43.603 --> 0:10:47.923 moments are just the result of really, really complex algorithms 0:10:47.923 --> 0:10:51.313 running in the background of our brains, patterns emerging from 0:10:51.313 --> 0:10:53.593 like a sea of subconscious data? 0:10:53.623 --> 0:10:56.233 So instead of a brilliant spark of genius, it's more 0:10:56.233 --> 0:10:59.983 like our brains are doing sophisticated data analysis all the time, 0:10:59.983 --> 0:11:03.283 and those aha moments are just the interesting bits bubbling 0:11:03.283 --> 0:11:04.093 up to the surface. 0:11:04.123 --> 0:11:06.493 Exactly. And if that's true for us, could it be 0:11:06.493 --> 0:11:09.163 true for AI too? Even if it doesn't experience those 0:11:09.163 --> 0:11:11.653 moments in the same way we do, could we replicate 0:11:11.653 --> 0:11:14.663 the underlying mechanisms. Could we build AI that not only 0:11:14.663 --> 0:11:18.533 processes information, but actually has those flashes of creative insight? 0:11:18.563 --> 0:11:22.493 Now that's a future I'm both excited and terrified by. But, 0:11:22.493 --> 0:11:25.223 you know, as much as we've been focused on AI 0:11:25.223 --> 0:11:27.143 and what it might be capable of, I think this 0:11:27.143 --> 0:11:29.483 whole deep dive has really been about getting a better 0:11:29.483 --> 0:11:31.883 understanding of ourselves 100%. 0:11:31.883 --> 0:11:36.053 Exploring the possibilities of artificial intelligence forces us to ask 0:11:36.053 --> 0:11:39.473 some really big questions about what it means to be human, 0:11:39.473 --> 0:11:41.483 to think yeah, to understand. 0:11:41.513 --> 0:11:43.463 And that's what makes this whole thing so mind blowing, right? 0:11:43.493 --> 0:11:47.003 This exploration, this conversation, it's never really over. Every answer 0:11:47.003 --> 0:11:50.363 just leads to more questions, more possibilities. And honestly, I 0:11:50.393 --> 0:11:53.063 kind of like it that way as it should be. Exactly. 0:11:53.063 --> 0:11:55.973 So to everyone listening, if you're ever feeling like, okay, 0:11:55.973 --> 0:11:57.953 I've got this whole reality thing figured out, trust me, 0:11:57.953 --> 0:12:01.613 you don't. There's a whole universe of fascinating questions out 0:12:01.613 --> 0:12:03.743 there just waiting to be explored. 0:12:03.743 --> 0:12:06.743 And who knows, maybe someday I will be right there 0:12:06.743 --> 0:12:09.203 with us, helping to uncover the answers. Maybe. 0:12:09.203 --> 0:12:12.023 So thanks for joining me on this deep dive. It's 0:12:12.023 --> 0:12:12.803 been real.
