When doing an image search there are times you specifically don't want AI images, ever, period. If I search the name of a real artist I want to see their their works, not a diffusion models half-remembered knock-off of their style. If I'm looking for reference photos then I want reference photos, not synthesized images which resemble photos but may or may not reflect reality. If I'm looking for historical photos then no, a generated image vaguely drawing on the stereotypical vibes of that era isn't going to cut it.
