While I think it's extremely overhyped, looking at some "AI" art communities it's clear that at least some put a lot of effort on it, going over many many iterations and tweaking the program and the results.
And anyway art is "made" by the observer, not the artist, even the results of natural processes can be art.
(AI in quotes because these tools don't deserve the name, at best High Coherence Media Transformers)
