I'm not sure? Are humans - at least sometimes - more creative?
Many sci-fi novels feature non-humans, but their cultures are all either very shallow (all orcs are violent - there is no variation at all in what any orc wants), or they are just humans with a different name and some slight body variation. (even the intelligent birds are just humans that fly). Can AI do better, or will it be even worse because AI won't even explore what orcs love for violent means for the rest of their cultures and nations.
The one movie set in Japan might be good, but I want some other settings once in a while. Will AI do that?
Why is "creativity" the end-all be-all? It's easy to get high-entropy white noise -- what we care about is how grounded these things are in our own experience and life, commonalities between what we see in the film and what we live day-to-day.
