I think you’d be hard pressed to find a group of people with minimal education in art who couldn’t reliably pice out the AI generated images. You might be able to trick them with abstract images or things intended to look like computer generated art that doesn’t have a complex or human subject matter.
Frankly humans and animals generated by these things look like blurry trash or are wrong on details in a way a human wouldn’t be, even intentionally. I’ve yet to see examples that don’t look kind of shitty.
