It bothers me in the same way art done by children bothers me, which is to say not much, but it’s usually pretty devoid of aesthetic value. Because they (AI, not children) draw on a huge variety of styles, they often also feel extremely generic, and like they don’t have any style of their own.
Some of them have been kind of funny because the poster had some sort of decent comedic idea. I’m happier to see this type.
