I don’t think the question is art vs not art. “Art” is an abstraction bestowed upon something by the viewer.
I think a lot of people are still struggling with this, but popular “art” is already largely devoid of humanity, and reduced to formulaic focus group fluff, and has been for a long, long time now. AI just streamlines the processes we already have.
Any additional debate on this will reduce to linguistics. You can - “I know it when I see it” - all you want, but that’s a cop out. The reality is that media which produces a specific neurochemical response in humans doesn’t, and never has required human input. A breathtaking landscape. A feeling of tranquility during snowfall. A kinship with an animal. An AI generated image. These are all the same process.
