The industry will shrink as the pipeline shrinks. I think there will be two skills that will remain valuable the coming years. Design and math/programming. Because you will still need someone with an artistic eye for world building and asset creation (like a concept artist) and you will need someone with the ability to describe behavior with math and code.

Producing stuff will be the cheapest and easiest part. Just like generating images or building simple websites with AI is now basically free.
