Art is in the eye of the beholder. Doesn't matter if it was created by a human, an insect, a computer program or even the arrangement of rocks by random weather events.
Art should give you a sense of wonder, amusement, a deep appreciation of the skills involved in its creation or (in the case of things like photography) delight in seeing how someone sees something in the world in a way you'd never previously thought of. Art should expand your mind (man). Sadly art collectors have turned the whole thing into a giant festival of snobbery and the older I get the more convinced I am that the art "markets" are primarily a front for money laundering.
I remember seeing Marcel DuChamp's "fountain" as a young kid and didn't get it at first - I thought "anyone could do that" and it was just another artist with their head up their arse. But then I read about DaDa and how it was sticking two fingers up at pompousness and pretentiousness and I loved it (and DaDa in general).
Personally I'm a big fan of AI generated art - the weirder the better ! and am looking forward to what it spews out next ("Killer AI Duck" has some superb videos on YouTube). I think it's a lot more interesting that some of the uninspiring "proper" art I've seen in galleries recently.
Really good art should make a giant exclamation mark pop into your brain ("Aha !")
P.S. Hopefully AI "art" can't be copyrighted too :)
