I'm trying to find a great story I read in an SF compilation book of some sort.
It was about a poet living in a world where we can simulate universes in computers, and people like him go in and basically plagiarize the art - stories, poetry - and sell it to people in our universe.
Problems occur when the universe in the simulation figure out how to do it, because it nests too many universes and it's too much data. At the end:
we realize his universe is collapsing because it's simulated too.
