Most people have terrible eyes for distinguishing content.

I’ve worked in CG for many years and despite the online nerd fests that decry CG imagery in films, 99% of those people can’t tell what’s CG or not unless it’s incredibly obvious.

It’s the same for GenAI, though I think there are more tells. Still, most people cannot tell reality from fiction. If you just tell them it’s real, they’ll most likely believe it.
