Bubble Bill
A fiction plot came to me in the car: an ASI constructs an airtight waterproof bubble around a town, and everyone is puzzled why, until suddenly it usheeschatrs in a Biblical flood that kills everyone in the world, except the people inside the bubble. They choose this town because someone inside of it was determined to be "the supreme human," a genetic and moral code that is exemplary of how all humans should be and live. It turns out it was just a regular guy who said "please" and "thank you" to this chatbots, a kind of "reverse sycophant." We find out, in a very Vince Vaughn-esque apocalyptic romcom, that he's a mediocre fallible guy, but more remarkably, also immune to the crooning and praise from both his neighbors and overlords. He has every opportunity to step into the role of messiah, but would really rather not, and instead continue his pre-flood existence.
