A holodeck and a human actor: a best-case scenario for AI filmmaking. Human actors reacting in human ways to whatever scenario the filmmaker invents, which is not much different from what goes on now.
The thing is, you can’t fake human, and maybe it’s not worth trying. Everything else in filmmaking—sets, props, locations, eldritch horrors—can be represented artistically and therefore generated with digital imaging. It’s the people you can’t fake.
Consider: we pay people to do nothing but be good at emoting. Certain people emote i.e. act more skillfully than others, and we make them millionaires and give them gold statues and big parties and all our attention. One individual, idiosyncratic human with their asymmetrical face and personality quirks and gut biome, singular among all other humans currently alive, can win the hearts of millions. You’re telling me a calculator (which is what a computer is, writ large) is going to be able to fake that any time soon?
AI research has over the years taken up billions of dollars, and we’re still nowhere near faking people. Maybe it can’t be done. A computer as intricately modeled as the human brain might need to be either the size of a mountain or be an actual biological brain, grown in situ.
We are clever soup. But we are like nothing else. We’re cheap to make, easy to teach, endlessly inventive. Why bother trying to mechanically replicate what’s already so abundant?
