With Pollock, he was exploring the process. The end result looks like splatters but it's actually really hard to make a fake. Also sometimes those splatters are because he was doing shit like throwing the paint into a jet engine, which is cool.

Andy Warhol can fuck himself, his whole gimmick was people will buy the dumbest stuff if you call it art, the whole thing was a gaff and a grift at the same time and everyone knew it but bought into it anyway.

However they are both superior to slop makers. Because art is about choice. Each color splatted onto a canvas and each color chosen to repeat on a silkscreen by those two was a choice they made. Bots don't make those choices, it's just stolen pictures turned to static turned to numbers and then covering words into numbers into static into an image. The prompter doesn't make a choice about the image and neither does the bot.
