This seems like an Innovator's Dilemma (adjacent) trap. The actors will prevent hollywood or the mainstream studios from using synthetic actors, writers, etc. so it will be left up to some completely new entity to create that infrastructure. It will happen anyway because it is so compelling, and there are tens of thousands of actors who never make a living who would happily become digital.
