That's cool, but I don't see why one would want to watch a movie like that.
For B-Roll it's different. I can somewhat see the why behind that. It's just to give your brain something to look at so that you don't have a voice-only podcast.
But movies OTOH are these creative endeavors where the shots _are_ the content instead of just augmenting the content.
This won't stop the industry from still trying to use this tech like that, of course.
Imagine a hybrid movie, where film maker spends $5000 filming a couple of actors, but uses $50 of AI shots for special effect or other footage that would have been completely out of budget before.
I mean, if you just want to claim that AI lacks soul, and its an abomination if every frame in film isn't make by a chemical process involving silver nitrate, like the good Lord intended, that's fine. But there are certainly film makers who don't share that sentiment.
