I think short term, yeah, I think so. Medium term and I think we'll see a bunch of model collapse or people will get tired of the same story line repeatedly so it won't be profitable (or won't be regaining the money they thought they'd save on actual creative folks). Long term, I have no fucking clue if they'll get around the fact that training AI on AI makes it even weirder.

Yup. Mountains of slop is gonna replace schlock. What was before schlock will soon be slop. Well, it won't be the end of schlock entirely. I'm sure we're still gonna get some schlock that's also slop. Slop schlock.

Probably kinda.

I imagine that someone who can't draw for crap using AI to create the visual component to their stories. They may also use AI to create character "voices" who say things in their specific manner

Manga production costs drop as a writer doesn't need as many skills to write them and the AI handles more of the heavy lifting when it comes to generating content.

Eventually one of these slop mangas becomes popular enough to get animated. Since it is animated, it becomes a lot easier to make. My guess is that the beginning looks like AI empowered rotoscoping, human actors provide the movements which become the basis of animated characters. You can even do voice modulation too, so the vocal performance gets swapped to the right voice.

These animes might be less popular, but if they are being made at a fraction of the cost of human animation.
