I had a photo of one of those tricked out camper vans with solar cells on top. I asked AI to write a story based on the photo in a post apocalyptic world. About five hundred words in the style of Steven King. It wasn't quite up to King's quality, but the story was actually not bad. I guess if we run out of things to read AI can always come up with something.
I suspect wee are already unknowingly reading things written AI, but it may not be up to writing fine literature, quite yet.
