on their own computer using open weight chinese models?

some people write fanfic, most just watch/read instead.
2) https://en.wikipedia.org/wiki/Rebel_Without_a_Crew explains how film maker will film, with whatever they have. AI will enable some people to make what is not financially feasible right now for a single person to do.
'Unique' movie/stories creation will continue.

Same question we have of 'AI generated code' vs 'this code was written by a person'.
