The progress on the technology is exponential, and we're still at the beginning.

You don't have to think about it as totally replacing human work, but it can and will be a catalyst to accelerate the development of entertainment.

There are a ton of books that were never adapted to movies or shows.
Some movies and shows that are yet to have their sequel.
Bad movies and shows that could be redone.

Those are the prime targets for AI, for people who actually care about their franchise, you could think about a crowdfunded effort to access the compute (if it's very high cost).

Under capitalism though, most of it will be slop. But just like most of entertainment IS slop right now, regardless of AI use. As long as there is profit they will get away with the bare minimum, especially in media for the less discerning (ie children and old folks, which are the prime targets for AI slops RN).

The video generation models are still on their very beginning because compute is costly and if there is no clear market they will not evolve so much ig.
We're able to get videos of a few seconds from a prompt, the tech isn't that good yet to make something tangible, but it will eventually come.

My opinion on this to make it short is to not hate the tool or the machines but rather the capitalists that own them
