I don't know how you figure an independent studio or individual will be able to keep pace with the likes of Hollywood or HBO. The premise is ridiculous. There's more to it than good cameras, good microphones, and some minimal computer processing. There's the story writing, script and dialogue, sound and sound engineering, sometimes CGI, the location and set that is immersive and complementary, and a slew of other stuff covered in the credits to contend with. Unless you think everyone on the planet is going to prefer blair witch style movies your future isn't close by, it's literally never coming.

Now you might say that AI can solve this problem, but unless you've got lots of people with the vision and ability to write unreasonably explicit prompts, that future is also way, way, WAY off and still improbable: consider how many pictures of people with hands and teeth there are and see how bad AI generations are. You can't give 30 Marvel movies as training data and expect the next Ironman to emerge from your fanfic write up.
