What do you consider a counterexample? Because I've been involved in local politics lately, and can say from experience that any foundation model is capable of more rational and detailed thought, and more creative expression, than most of the beloved members of my community.

If you're comparing AI to the pinnacle of human achievement, as another commenter pointed to Shakespeare, then I think the argument is already won in favor of AI.

I recently watched "Come See Me in the Good Light", about the life and death of poet Andrea Gibson. I find their poetry very moving, precisely because it's dripping with human emotion.

Or at least, that's the story I tell myself. The reality is that I perceive it to be written by a human full of emotion. If I were to find out it was AI, I would immediately lose interest, but I think we're already at the point where AI output is indistinguishable from human output in many cases, and if I perceive art to be imbued with human emotion, the actuality of it only matters in terms of how it shapes my perception of it.

I'm not really sure where we'll go with that from here. Maybe art will remain human-created only, and we'll demand some kind of proof of its provenance of being borne of a human mind and a human heart. Or maybe younger generations will really care only about how art makes them feel, not what kind of intelligent entity made it. I really don't know.
