> consciousness cannot be proven from the outside by definition.

If it invents a concept of consciousness, I don't think a being without consciousness would invent a concept like consciousness to describe itself.

So when we have LLM zero that doesn't have the word "consciousness" and no human inputs and it still starts talking about consciousness then I think we can say it is conscious. Humans did this, so I'd expect an AGI to be able to do it as well if it is conscious.
