There's a popular youtuber named Joel Haver who films videos, then uses an AI tool to convert them into animations, so they can be magically put into a space or fantasy setting.
AI dungeon is an text adventure where the content is AI-generated.
I also imagine tools similar to Github Co-pilot for other markets. Some AI could generate music or video games levels based on inputs from a user, then the user can take or modify the best bits. The goal hopefully being that they get something no human could have thought up, instead of just generating a bunch of mediocre content.
