The reward in Hollywood and most professional fields is about who makes the best/most cost efficient product no matter what.

If the same was true for chess or go then players would be using computer assistance in every top level game.

I see the point you're making, and well made, but I think it also highlights a distinction in problems between the two. In the case of go, people who want to play go are the main motivating force. In the case of movies, I don't give a damn about Hollywood, the money, the studios, the IP, the actors. I only care about the quality of the film. Maybe the autuer, if there is one.

AI changing conceptions about chess or go is very different than generative Ai which can radically change the means of how something is produced. I'm still going to play go because I love it. Meanwhile, I would happily cut out film studios (as we know them) if it meant I got to watch quality cinema.
