There are plenty of great outsider storytellers and artists. Youtube is proof of this. People mostly do comedy on youtube because that's what the medium supports on a low budget, but AI is going to change that.
I'm really not seeing how that would happen from these examples. It would seem like achieving an adequate, directorial level of control would require writing a novel -- or, anyway, more than a conventional screenplay -- to get the AI to make the movie you wanted.
There is so much that has to be conveyed in making a film, if you want it to say something particular.

And? What's the problem with that? You seem to be locked in a "prompt to get a movie" mindset.
Those are the examples provided. When they deliver pro tools for generating movie clips, I will be more convinced, but that hasn't remotely happened yet.
