"It wouldn't make a difference" - To whom? And how do you know? Even if a bot passes the Turing test, a community where there isn't any creativity or new information will die out. LLM is not the be all and end all of the human experience.

To take it further. even if we were all in the matrix, the statement "it wouldn't make a difference" is not true - philosophically speaking.

Also, humans have a circular reference with society at-large. Humans shape society, and society shapes humans. So something completely different might shape future societies, but I'd rather discuss the situation as it exists today, rather than an imagined future.
