I think that the real ceiling for quality content, film or no, is the writing and there's no way to generate more high-quality writers on demand. Editing? You can walk down a street in Brooklyn and find an editor no problem. Cinematography? Art schools produce tons of people who are good at taking pretty pictures.
But there's only one Charlie Kaufman. There's only one Aaron Sorkin. There's only one Quintin Tarantino. There's just the Coen Brothers. No amount of art school or trial and error can make you a compelling writer.
So we're at a point where there's an abundance of people who can help you make a movie technically, an abundance of people who will finance a movie, an abundance of people who will act in your movie (everyone I remember from the 90s is still available as an actor on top of everyone else trying to be one) but just not an abundance of good writers and that'll probably always be true.
