> I wouldn't be surprised if the "AI Slop" art style wasn't already inspiring human artists. Maybe there are already painters out there doing portraits of people with the wrong number of fingers.

People adopt art styles because they like something about them, the aesthetic or what they represent. I don't think there are enough human artists who like AI slop (they tend to despise it categorically) enough to want to imitate it, unless it's as some form of satire. They aren't going to do so simply because it exists.
