You make a good point. I'm just spitballing here, but I think what sets generative art apart for me is the element of deception.

I'd be perfectly fine with a hypothetical world in which all generated art is clearly denoted as such. Like you said, art is in the eyes of the beholder. I welcome a world in which AI art lives side-by-side with traditional art, but clearly demarcated.

Unfortunately, the reality is very different.

AI art inherently tries to pass off as if it were made by a human. The result of the tools released in the past year is that my relationship with media online has become adversarial. I've been tricked in the past by AI music and images which were not labelled as such, which fosters a sort of paranoia that just isn't there with the examples you mentioned.
