I’m pretty sure Mr Spielberg DOES something. If he does absolutely nothing, I really doubt the phrase “directed movie indicates a level of quality” can have any level of truth in a general case.

Ai is just another tool, it doesn’t do anything by itself, in the hands of a person with a great story it can be a great tool to help write it. In the hands of a bad writer it will probably just create bad content. Ai is a tool controlled by a person.

Do you really care if Spielberg’s team manually edits the movie or uses an AI powered video editing tool? In the end Spielberg is responsible for the end quality of the movie.
