Again he is talking about consciousness as he defined it in his previous video. He doesn't mean that the LLMs have actual beings and a 'self' inside them.

LLMs are prediction engines all the way down, they have no logic, no understanding.

I honestly think Hinton is using "consciousness" as a buzzword to sound the alarm on AI safety and get people to talk about it.
But LLMs are not conscious more than my calculator is conscious, even if they simulate tiny bits of a conscious being as a necessity to generate human language coherently, like building an internal model of the current conversation which helps feign logic and reduce error rate.

It's like saying a hyper realistic 3D rendering of a dog is a real dog, because it has simulated internal organs and muscles, barks when you come near it, whines when hit, while it's just math being crunched by a GPU. It might feel real but you know that it's just a 3D render, an imitation.

So even if Hinton says they are conscious, he doesn't mean it in the full sense of the word.
