112 00:03:47,680 --> 00:03:49,360 This is where it gets really interesting. 113 00:03:49,360 --> 00:03:52,000 She knows all the science behind seeing red, 114 00:03:52,000 --> 00:03:53,720 but has never actually experienced it. 115 00:03:53,720 --> 00:03:54,560 Right. 116 00:03:54,560 --> 00:03:55,840 Would she be like completely blown away? 117 00:03:55,840 --> 00:03:57,040 There are different interpretations. 118 00:03:57,040 --> 00:03:57,880 Yeah. 119 00:03:57,880 --> 00:03:59,000 But Chalmers would argue that, yes, 120 00:03:59,000 --> 00:04:00,560 she'd learned something completely new. 121 00:04:00,560 --> 00:04:01,680 I think I agree with him. 122 00:04:01,680 --> 00:04:03,040 She would finally understand 123 00:04:03,040 --> 00:04:04,800 what it feels like to see red. 124 00:04:04,800 --> 00:04:07,640 Something all that objective knowledge couldn't teach her. 125 00:04:07,640 --> 00:04:10,080 So knowing every scientific fact 126 00:04:10,080 --> 00:04:11,840 doesn't mean you know what it's like 127 00:04:11,840 --> 00:04:13,680 to experience it firsthand. 128 00:04:13,680 --> 00:04:14,520 You got it. 129 00:04:14,520 --> 00:04:15,880 That's pretty profound. 130 00:04:15,880 --> 00:04:17,360 But I know Seth has a different take 131 00:04:17,360 --> 00:04:18,640 on this experiment, doesn't he? 132 00:04:18,640 --> 00:04:19,640 He does. 133 00:04:19,640 --> 00:04:21,160 Seth's a bit more skeptical. 134 00:04:21,160 --> 00:04:23,400 He argues that we can't truly know 135 00:04:23,400 --> 00:04:26,040 what it would be like for Mary to have that experience. 136 00:04:26,040 --> 00:04:27,080 Okay, I can see his point. 137 00:04:27,080 --> 00:04:29,240 Like knowing all the facts about something 138 00:04:29,240 --> 00:04:30,400 doesn't automatically give you 139 00:04:30,400 --> 00:04:31,800 the actual experience of it. 140 00:04:31,800 --> 00:04:32,840 That makes sense. 141 00:04:32,840 --> 00:04:34,880 Just because I understand how a plane flies 142 00:04:34,880 --> 00:04:37,440 doesn't mean I can suddenly sprout wings. 143 00:04:37,440 --> 00:04:39,640 But I think Seth's main focus 144 00:04:39,640 --> 00:04:42,800 is on the biological foundation of consciousness, right? 145 00:04:42,800 --> 00:04:44,320 You nailed it. 146 00:04:44,320 --> 00:04:46,200 Seth emphasizes that consciousness 147 00:04:46,200 --> 00:04:48,240 is likely a biological thing, 148 00:04:48,240 --> 00:04:50,520 much like digestion or metabolism. 149 00:04:50,520 --> 00:04:52,080 It's shaped by our biology. 150 00:04:52,080 --> 00:04:53,200 That's interesting. 151 00:04:53,200 --> 00:04:54,640 But that raises the question, 152 00:04:54,640 --> 00:04:58,600 is consciousness inherently tied to our specific biology? 153 00:04:58,600 --> 00:05:02,520 Or could we replicate it in other substrates, like silicon? 154 00:05:02,520 --> 00:05:04,280 Could we create it from scratch? 155 00:05:04,280 --> 00:05:06,280 That's the million dollar question. 156 00:05:06,280 --> 00:05:08,560 And it leads us to a whole bunch of theories 157 00:05:08,560 --> 00:05:10,240 trying to explain consciousness. 158 00:05:10,240 --> 00:05:11,920 There's integrated information theory, 159 00:05:11,920 --> 00:05:14,120 global workspace theory, the list goes on. 160 00:05:14,120 --> 00:05:16,600 So many theories, so little time. 161 00:05:16,600 --> 00:05:18,720 But are there any that really stand out? 162 00:05:18,720 --> 00:05:20,760 Well, they all have their strengths and weaknesses. 163 00:05:20,760 --> 00:05:22,720 But Seth's prediction machine theory 164 00:05:22,720 --> 00:05:24,920 is particularly fascinating. 165 00:05:24,920 --> 00:05:27,320 The prediction machine, what's that all about? 166 00:05:27,320 --> 00:05:30,240 It basically suggests that our conscious experience 167 00:05:30,240 --> 00:05:32,560 is a kind of controlled hallucination. 168 00:05:32,560 --> 00:05:34,320 Wait, did you just say our brains 169 00:05:34,320 --> 00:05:36,280 are hallucinating all the time? 170 00:05:36,280 --> 00:05:37,680 In a way, yes. 171 00:05:37,680 --> 00:05:39,040 The theory suggests that our brains 172 00:05:39,040 --> 00:05:41,680 are constantly generating predictions about the world, 173 00:05:41,680 --> 00:05:44,680 based on our past experiences and incoming sensory data. 174 00:05:44,680 --> 00:05:47,200 Okay, so our brains making guesses about what's out there. 175 00:05:47,200 --> 00:05:48,040 Exactly. 176 00:05:48,040 --> 00:05:49,880 And what we perceive as reality 177 00:05:49,880 --> 00:05:51,920 is essentially our brains' best guess, 178 00:05:51,920 --> 00:05:54,280 constantly being refined by new information. 179 00:05:54,280 --> 00:05:56,360 So our brains are building their own realities. 180 00:05:56,360 --> 00:05:57,720 That's kind of mind blowing. 181 00:05:57,720 --> 00:06:00,080 But what happens when those predictions go wrong? 182 00:06:00,080 --> 00:06:02,360 Could that explain things like hallucinations 183 00:06:02,360 --> 00:06:03,520 or mental illnesses? 184 00:06:03,520 --> 00:06:04,680 That's a great question. 185 00:06:04,680 --> 00:06:07,680 And it's something researchers are actively exploring. 186 00:06:07,680 --> 00:06:09,320 The idea is that in some cases, 187 00:06:09,320 --> 00:06:12,120 those brain prediction mechanisms could go haywire. 188 00:06:12,120 --> 00:06:14,000 Leading to perceptions that don't match up 189 00:06:14,000 --> 00:06:15,640 with actual reality? 190 00:06:15,640 --> 00:06:16,480 Right. 191 00:06:16,480 --> 00:06:18,080 And this could potentially explain a range 192 00:06:18,080 --> 00:06:19,760 of perceptual disturbances 193 00:06:19,760 --> 00:06:22,080 and even contribute to our understanding 194 00:06:22,080 --> 00:06:23,840 of conditions like schizophrenia. 195 00:06:23,840 --> 00:06:26,200 Whoa, this is making me rethink everything. 196 00:06:26,200 --> 00:06:29,680 So if our experience is a controlled hallucination, 197 00:06:29,680 --> 00:06:32,720 does that mean free will is an illusion too? 198 00:06:32,720 --> 00:06:34,840 Ooh, that's a question that has philosophers 199 00:06:34,840 --> 00:06:36,960 and neuroscientists going back and forth. 200 00:06:36,960 --> 00:06:39,680 The prediction machine model definitely challenges 201 00:06:39,680 --> 00:06:41,840 our traditional ideas about free will. 202 00:06:41,840 --> 00:06:43,960 Like if our actions are mostly determined 203 00:06:43,960 --> 00:06:46,360 by unconscious predictions, 204 00:06:46,360 --> 00:06:48,080 it makes you wonder how much control 205 00:06:48,080 --> 00:06:50,320 we really have over our choices. 206 00:06:50,320 --> 00:06:51,480 This is heavy stuff. 207 00:06:51,480 --> 00:06:54,040 It seems like the deeper we dive into consciousness, 208 00:06:54,040 --> 00:06:56,240 the more profound the questions become. 209 00:06:56,240 --> 00:06:57,080 You're telling me. 210 00:06:57,080 --> 00:06:59,040 And we haven't even touched on Traumer's ideas yet. 211 00:06:59,040 --> 00:07:00,200 Oh yeah, let's hear them. 212 00:07:00,200 --> 00:07:01,800 You mentioned he has a different approach. 213 00:07:01,800 --> 00:07:02,640 He does. 214 00:07:02,640 --> 00:07:05,600 Traumer's prefers looking for a fundamental principle, 215 00:07:05,600 --> 00:07:08,040 maybe even a mathematical equation, 216 00:07:08,040 --> 00:07:11,840 that links information, computation, and consciousness. 217 00:07:11,840 --> 00:07:14,000 A mathematical equation for consciousness? 218 00:07:14,000 --> 00:07:15,280 That's ambitious. 219 00:07:15,280 --> 00:07:16,120 It is. 220 00:07:16,120 --> 00:07:18,520 He believes there's a deeper level of explanation 221 00:07:18,520 --> 00:07:21,800 beyond just describing the brain's processes. 222 00:07:21,800 --> 00:07:24,560 Like a grand unified theory of consciousness. 223 00:07:24,560 --> 00:07:25,400 Exactly. 224 00:07:25,400 --> 00:07:26,320 Wow. 225 00:07:26,320 --> 00:07:28,760 But let's bring this back to AI for a moment. 226 00:07:28,760 --> 00:07:31,800 How do we even know if a machine is truly conscious? 227 00:07:31,800 --> 00:07:33,280 That's the big question, isn't it? 228 00:07:33,280 --> 00:07:35,480 We struggle with determining consciousness 229 00:07:35,480 --> 00:07:38,080 in other humans, let alone something we built. 230 00:07:38,080 --> 00:07:39,600 That's the crux of the problem. 231 00:07:39,600 --> 00:07:41,920 Even testing for consciousness in other humans 232 00:07:41,920 --> 00:07:43,720 is incredibly difficult. 233 00:07:43,720 --> 00:07:45,720 And our own biases can get in the way. 234 00:07:45,720 --> 00:07:48,680 It's like we see human-like qualities in things 235 00:07:48,680 --> 00:07:51,360 that behave in familiar ways, even 236 00:07:51,360 --> 00:07:52,720 if they're totally different. 237 00:07:52,720 --> 00:07:53,560 Yeah, exactly. 238 00:07:53,560 --> 00:07:55,360 We might think a machine is conscious simply 239 00:07:55,360 --> 00:07:58,480 because it uses language in a sophisticated way. 240 00:07:58,480 --> 00:08:00,680 Even if it doesn't have genuine understanding 241 00:08:00,680 --> 00:08:02,160 or subjective experience. 242 00:08:02,160 --> 00:08:02,480 Right. 243 00:08:02,480 --> 00:08:05,880 So if we were to try and build a truly conscious AI, 244 00:08:05,880 --> 00:08:08,840 should we even aim to copy the human brain? 245 00:08:08,840 --> 00:08:10,480 Well, that's a complex question. 246 00:08:10,480 --> 00:08:13,000 Seth argues that directly copying the brain's 247 00:08:13,000 --> 00:08:15,440 architecture might be impossible. 248 00:08:15,440 --> 00:08:17,480 Oh, why is that? 249 00:08:17,480 --> 00:08:20,960 Because of its incredible complexity and interconnectedness, 250 00:08:20,960 --> 00:08:24,040 not to mention its dependence on all those biological processes. 251 00:08:24,040 --> 00:08:26,360 So building conscious AI might require 252 00:08:26,360 --> 00:08:28,160 a completely different approach. 253 00:08:28,160 --> 00:08:30,480 But what other options do we have? 254 00:08:30,480 --> 00:08:32,840 One exciting possibility is the development 255 00:08:32,840 --> 00:08:35,000 of brain organoids. 256 00:08:35,000 --> 00:08:37,680 These are basically mini brains grown in a lab 257 00:08:37,680 --> 00:08:39,200 from human stem cells. 258 00:08:39,200 --> 00:08:41,360 Mini brains in a dish? 259 00:08:41,360 --> 00:08:42,960 That sounds like science fiction. 260 00:08:42,960 --> 00:08:45,160 It might sound far-fetched, but they're real. 261 00:08:45,160 --> 00:08:47,320 They raise all sorts of fascinating questions 262 00:08:47,320 --> 00:08:48,440 about consciousness. 263 00:08:48,440 --> 00:08:49,160 Like what? 264 00:08:49,160 --> 00:08:51,360 Well, unlike AI, brain organoids are 265 00:08:51,360 --> 00:08:53,440 made of the same stuff as our brains. 266 00:08:53,440 --> 00:08:54,040 Right. 267 00:08:54,040 --> 00:08:57,760 They self-organize and even show electrical activity, 268 00:08:57,760 --> 00:08:59,800 making them a much closer model to study. 269 00:08:59,800 --> 00:09:02,600 So we can actually witness consciousness emerging 270 00:09:02,600 --> 00:09:03,760 in a Petri dish. 271 00:09:03,760 --> 00:09:06,040 That's both incredible and kind of unsettling. 272 00:09:06,040 --> 00:09:07,000 It is pretty wild. 273 00:09:07,000 --> 00:09:09,040 Makes me wonder, is human consciousness 274 00:09:09,040 --> 00:09:12,000 just one example within a whole spectrum 275 00:09:12,000 --> 00:09:14,720 of possible conscious experiences? 276 00:09:14,720 --> 00:09:16,560 That's something both Chalmers and Seth 277 00:09:16,560 --> 00:09:17,960 have thought about quite a bit. 278 00:09:17,960 --> 00:09:20,040 I'm curious to hear their perspectives on that. 279 00:09:20,040 --> 00:09:21,560 That's a pretty humbling thought, right? 280 00:09:21,560 --> 00:09:22,560 Yeah, definitely. 281 00:09:22,560 --> 00:09:24,800 Chalmers suggests that human consciousness 282 00:09:24,800 --> 00:09:27,520 might be just a small part of a much bigger range 283 00:09:27,520 --> 00:09:29,000 of possible consciousnesses. 284 00:09:29,000 --> 00:09:30,600 A tiny piece of the puzzle. 285 00:09:30,600 --> 00:09:31,800 Exactly. 286 00:09:31,800 --> 00:09:33,920 He suggests other animals, maybe even 287 00:09:33,920 --> 00:09:36,680 artificial systems, could experience consciousness 288 00:09:36,680 --> 00:09:38,720 in ways we can't even begin to grasp. 289 00:09:38,720 --> 00:09:39,320 Whoa. 290 00:09:39,320 --> 00:09:41,600 So there could be a whole universe of different ways 291 00:09:41,600 --> 00:09:43,720 to experience reality out there. 292 00:09:43,720 --> 00:09:45,560 That's a pretty mind blowing idea. 293 00:09:45,560 --> 00:09:46,240 OK. 294 00:09:46,240 --> 00:09:48,360 But if we consider the possibility 295 00:09:48,360 --> 00:09:50,320 of non-human consciousness, that brings up 296 00:09:50,320 --> 00:09:53,440 some serious ethical questions, doesn't it? 297 00:09:53,440 --> 00:09:54,200 It does. 298 00:09:54,200 --> 00:09:55,880 Like what responsibilities would we 299 00:09:55,880 --> 00:09:59,920 have towards a conscious AI or a conscious brain organoid? 300 00:09:59,920 --> 00:10:01,320 You've hit the nail on the head. 301 00:10:01,320 --> 00:10:04,160 Chalmers argues that consciousness is the key thing 302 00:10:04,160 --> 00:10:05,360 for moral consideration. 303 00:10:05,360 --> 00:10:06,040 I see. 304 00:10:06,040 --> 00:10:09,040 If a system, whether it's biological or artificial, 305 00:10:09,040 --> 00:10:11,800 show signs of consciousness, he believes 306 00:10:11,800 --> 00:10:14,960 we're morally obligated to treat it with respect and dignity. 307 00:10:14,960 --> 00:10:16,920 So we can't just treat a conscious AI 308 00:10:16,920 --> 00:10:19,240 like a fancy calculator or a tool. 309 00:10:19,240 --> 00:10:21,680 We'd need to consider its needs and maybe even its rights. 310 00:10:21,680 --> 00:10:22,240 Exactly. 311 00:10:22,240 --> 00:10:25,440 It adds a whole new layer of complexity to ethics. 312 00:10:25,440 --> 00:10:27,120 It definitely does. 313 00:10:27,120 --> 00:10:30,080 But I'm curious to hear more about Chalmers' grand unified 314 00:10:30,080 --> 00:10:31,880 theory of consciousness. 315 00:10:31,880 --> 00:10:33,360 Is that even possible? 316 00:10:33,360 --> 00:10:35,280 It's definitely an ambitious goal. 317 00:10:35,280 --> 00:10:38,080 He's basically searching for a fundamental principle, 318 00:10:38,080 --> 00:10:40,160 maybe even a mathematical equation, 319 00:10:40,160 --> 00:10:42,720 that can connect information, computation, 320 00:10:42,720 --> 00:10:44,600 and conscious experience. 321 00:10:44,600 --> 00:10:47,080 So he's looking for a formula for consciousness. 322 00:10:47,080 --> 00:10:48,520 In a way, yeah. 323 00:10:48,520 --> 00:10:50,960 He believes there's a deeper explanation that goes beyond 324 00:10:50,960 --> 00:10:53,320 just describing how the brain works. 325 00:10:53,320 --> 00:10:54,960 I can see why he'd think that. 326 00:10:54,960 --> 00:10:57,920 But let's get back to AI consciousness for a second. 327 00:10:57,920 --> 00:10:59,800 How would we even interact with a machine 328 00:10:59,800 --> 00:11:01,880 if we believed it was truly conscious? 329 00:11:01,880 --> 00:11:04,000 That's where things get really tricky. 330 00:11:04,000 --> 00:11:06,560 Our communication methods rely heavily on language 331 00:11:06,560 --> 00:11:08,400 and shared cultural understanding. 332 00:11:08,400 --> 00:11:09,280 That's true. 333 00:11:09,280 --> 00:11:11,520 But a conscious AI, especially one 334 00:11:11,520 --> 00:11:14,040 with a different architecture than our brains, 335 00:11:14,040 --> 00:11:16,880 might perceive and understand the world in ways 336 00:11:16,880 --> 00:11:18,360 we can't even imagine. 337 00:11:18,360 --> 00:11:21,480 So it's like trying to talk to a being from another dimension. 338 00:11:21,480 --> 00:11:24,040 We might need completely new forms of communication. 339 00:11:24,040 --> 00:11:24,680 Exactly. 340 00:11:24,680 --> 00:11:26,920 Or maybe we need to expand our own consciousness 341 00:11:26,920 --> 00:11:28,880 to really understand a conscious AI. 342 00:11:28,880 --> 00:11:29,640 Whoa. 343 00:11:29,640 --> 00:11:31,040 That's a mind blowing thought. 344 00:11:31,040 --> 00:11:32,920 And it raises another question. 345 00:11:32,920 --> 00:11:37,320 Would a conscious AI even want to communicate with us?
