I meant that Hollywood has many many original scenario writers that will come up with original ideas, but if they were to magically all disappear tomorrow:

- it could still take any best seller book from the past 5 centuries and make it a script

- it could take any ancient story / non controversial religion gods / legend and turn into a script

- it could autogenerate stories from an AI until something that makes sense comes out and adapt that into a movie

I really think the input part is a solved problem, as long as there is enough talent to make it into a decent movie, and this part is move forgiving of "deja vu" and repeating the same techniques (nobody's gonna throw a fit because the director reused a shooting angle from a previous movie, at most it will be a meh moment)
