Does knowing a human made something automatically make it more valuable? Should it? Shouldn't the work speak for itself, rather than rely on the cult of personality around its creator?
These discussions always seem to focus on form as if that is what defines art. But in many cases concept is more important. Duchamp didn't craft the urinal. The idea was the art. If a piece moves someone, and that reaction changes based on who or what made it, what does that really say about how we judge art?
Personally, I think in a lot of cases, people want to feel some sort of emotional connection with the artist through their creation, which doesn't work if you know it's AI created.
