There will always be a difference between generated content and "the real deal". Even if both kinds of content feed into a fantasy, the human made kind has the allure of potentially (however slim the chance is) being with the actors in real life. That will never happen with generated characters.
In the back of the mind there will always be the knowledge that generated content is synthetic and imagining what it would feel like being with an actor is futile, as they don't exist. Which will cement human made content for the group who cares about such things.
That is the Achilles heel of AI. Pinocchio will never be a real boy.
