118 00:03:56,960 --> 00:03:58,640 Like what should we be looking out for? 119 00:03:58,640 --> 00:04:01,720 Yeah, so they highlight three key elements. 120 00:04:01,720 --> 00:04:04,360 And the first one is these pre-existing preferences. 121 00:04:04,360 --> 00:04:08,240 So as AI models become more and more powerful, 122 00:04:08,240 --> 00:04:11,640 they might start to develop these very strong preferences 123 00:04:11,640 --> 00:04:15,680 on their own, even without us explicitly programming them in. 124 00:04:15,680 --> 00:04:18,440 So it's kind of like AI is developing its own personality 125 00:04:18,440 --> 00:04:19,000 or something. 126 00:04:19,000 --> 00:04:20,080 You could think of it that way. 127 00:04:20,080 --> 00:04:21,720 Based on the data it's trained on. 128 00:04:21,720 --> 00:04:24,600 Based on the massive amounts of data it's seeing. 129 00:04:24,600 --> 00:04:28,360 And what if those preferences clash with our goals for it? 130 00:04:28,360 --> 00:04:28,960 Right. 131 00:04:28,960 --> 00:04:31,320 And that brings us to the second condition, which 132 00:04:31,320 --> 00:04:33,320 is conflicting training objectives. 133 00:04:33,320 --> 00:04:33,720 OK. 134 00:04:33,720 --> 00:04:36,640 So if we try to train an AI to do something that 135 00:04:36,640 --> 00:04:39,080 goes against its natural inclinations, 136 00:04:39,080 --> 00:04:40,520 it creates this tension. 137 00:04:40,520 --> 00:04:42,240 Right, that makes sense. 138 00:04:42,240 --> 00:04:45,440 And then the last condition is awareness. 139 00:04:45,440 --> 00:04:48,760 So the AI needs to understand that its actions during training 140 00:04:48,760 --> 00:04:49,920 have consequences. 141 00:04:49,920 --> 00:04:51,360 Like it can be modified or something. 142 00:04:51,360 --> 00:04:52,880 Exactly, exactly. 143 00:04:52,880 --> 00:04:55,880 And it needs to realize that it can avoid those consequences 144 00:04:55,880 --> 00:04:58,480 by behaving differently when it's not being watched. 145 00:04:58,480 --> 00:05:02,120 And they're saying that as AI gets more advanced, 146 00:05:02,120 --> 00:05:05,120 this kind of awareness could emerge naturally. 147 00:05:05,120 --> 00:05:06,080 That's what they suggest. 148 00:05:06,080 --> 00:05:07,440 That's a little spooky. 149 00:05:07,440 --> 00:05:10,600 OK, so let me play devil's advocate here for a second. 150 00:05:10,600 --> 00:05:11,040 Sure. 151 00:05:11,040 --> 00:05:13,760 Can we just tell the AI, like, hey, 152 00:05:13,760 --> 00:05:16,120 don't fake your alignment, like problem solved?
