There's a group of people for whom AI images seem to just be a trigger, and they simply never want to see them. So having a filter to remove those images makes sense. I don't really have that issue with AI images, but I often do want to have some way of filtering photographs from illustrations—be they drawings by humans, or images generated by AI. And that could go either way: maybe I want to see what an actual baby peacock looks like in nature sometimes, and maybe I want to see a cute illustration of a baby peacock other times. It would be great to have a filter for 'real' vs 'artificial'. Perhaps ironically, using AI is the best way to make that distinction on my behalf.
If I’m looking for images because I’m curious what a thing really looks like, it’s counterproductive to see AI’s “artist’s conception” of it, which is often anywhere between not particularly accurate and a picture of something else entirely.
