That last point is also important; if it's not surprising, people will just accept it without being too critical about it. And since these AI tools are trained with real / existing content, creating realistic-enough content will be the norm. I think the first big AI generators - dall-e and co - had their model trained on more fantastical / artistic sources, and used that primarily as their model, also because realistic generation (like humans) wasn't yet good enough, or too uncanny. But uncanny and art work well together.
