That's not the entire point of art. There are many points of art: inspiration, expression, fun, interior design, exterior design, etc.

AI can create art that covers all of the above, except maybe expression.

Interior and exterior design are applications of art/design, not reasons. The other three things are human experiences. I’m not saying a human cannot create art using gen AI. In fact, whoever thought of making Gemini generate a “17th century British monarch eating watermelon” created a piece of art as provocative commentary on gen AI itself. But if we remove the artists and just have machines churning out materials to consume, maybe based on some signal of consumer preferences, I do not believe that is art. What fun, inspiration, or expression would be enjoyed by either creator or consumer?
