Fundamentally, AI image creators stitch together images, then try to apply an art style.
You might call it “unique” because it stitches things together wrong (hello 10 fingers on one hand), but it is still fundamentally just copying, pasting, and then deforming lines together.
People claiming that AIs understand what they’re doing and that what AIs do is not fundamentally copying and pasting are the ones who have the burden of proof here.
