The answer to this question after a lot of reflection: games.

AI can slop fork or clone existing software well, but a clone of an existing game is pointless, it's basically guaranteed to be derivative and worse than the original game, and games aren't so expensive that you can't just buy the original. AI can't know if new mechanics or angles to an existing genre will feel good to play, or if a new genre is fun, that requires a human to experience the game in its totality.

Games are also very resilient to sloppy AI coding, and if an indy game crashes nobody is getting paged.
