It can already happen... Kaliyuga's pixel art diffusion can be used to generate backgrounds or even art and assets for pixel art games. She is also working on a sprite sheet diffusion model, so we can make the characters with that too!

@dbddv01 is already making comics... only a matter of time before novels come out. And people are already using the GPT3 models to generate code for pretty much any task...

Exciting times!
