The quantity/quality tradeoff is horrific. And I speak as someone who's watched hundreds of low budget "B" movies. AI is going to allow churning out vastly more movies than anyone can ever watch. Even if some might be good, the average quality goes down, and the adverse selection problem of trying to decide if something is going to be worth committing two hours to becomes harder when you have to scroll for longer and longer distances.

There's already a bit of a fatigue with CGI and the "flat lighting" Netflix TV style. AI is just going to make that worse. Mind you, I'm old enough that I would call any movie where more than 50% of the frame for more than 50% of the runtime was never real objects and created entirely on computer "animation". It's a subtly different discipline.

But yes, there's going to be a lot of it, and it's going to rack up a lot of Netflix watch hours, in the same way that "4k crackling fireplace" does.
