The most exciting long-term effect of this, in my view, will be the democratization of storytelling. The sort of stories we get given today by Hollywood / Netflix / Apple TV / national TV channels tend towards duplication and are dominated by particular ideologies and beliefs. The lack of optimistic sci-fi is one symptom of this. I think it happens due to budget increases driving centralization. YouTube is far more diverse and vibrant, but even great YouTube content is very low budget compared to a typical TV show or film. Combining Epic's tech stack (Unreal 5, Quixel MegaScans, Metahuman) with AI generated assets could break this and allow for the production of stories that would be considered too risky, niche or ideologically unacceptable by existing studios. By allowing the assets to be forked it will also become possible to scale up story production far beyond the episodes-in-seasons format required by conventional TV, in which fanfic and canonical lore blur together with "canonical" becoming the set of fan-produced episodes that are blessed by the original creators.
