Imagine a plot like Idiocracy but AIdiocracy, where someone wakes up in a future where all books, movies, music, art and architecture are created by AIs, and all *consumed* by AIs. Humans are asleep or dead behind their curator bots.
Everything runs, but it's all nonsense. Billboards sell plates of cooked toilet paper, stairways go in circles, boy bands play car crash sounds by stuffing string into their nostrils. Machines guess what humans want and the machines approve.
