Why would Disney fear you, though?

They'll still own all of the money-making IP that your models are trained on. You won't actually be able to get away with "X in the style of Disney or Y in the style of Pixar." And they'll have their own in-house models, far more expensive and powerful (likely through regulation) than you'll be able to afford.

You aren't talking about competition, you're talking about emulation. Putting an inferior version of existing properties on the market like The Asylum does.

I watched all of the links you provided. The "live action rotoscoped film" didn't need AI. They could have rented a knight costume or did that in AE, it wouldn't have even been that expensive. It wasn't even a good example of what rotoscoping could do - and I can actually accept rotoscoping and motion capture as a legitimate use of LLMs.

The concept for the Predator sketch was lame and it's ripping off the style of an Joel Haver, an animator with actual comedy talent. That legitimately kind of makes me mad. That's exactly the sort of thing that makes people hate AI. You aren't even ripping off a corporation here, which I could at least respect in abstract.

The Superman parody was generic and derivative, but it looked competent. Didn't really look like Robot Chicken though. The way they did the mouths was weird. And the whole plot revolved around a problem that was never actually a problem in the franchise.

The Grinch "anime" didn't look like a good anime. It looked like the kind of thing people criticize when an anime studio cuts costs for a second season. Still frames and very little animation. Inconsistent and generic style.

The horror movie posted below? The "blood" looked awful a lot of the time. The cinematography, as such, didn't carry the story at all. It isn't shot or cut the way an actual movie would be. The actors weren't compelling, the script was tepid.

Understand, I'm really trying not to just shit on this because it's AI, I'm trying to approach it as art because that's what it purports to be. And I can concede that the technical capability of AI has advanced dramatically in this field. They did a Robot Chicken and they did a Joel Haver and I saw a 90s cartoon but... it's bad art. I see no sense of actual unique creative vision anywhere. No sense of an actual artist trying to express something. Nothing that tells me "this could only have been done by AI, and would have been impossible beforehand."

It's like AI people think all you need is the aesthetic, and that the aesthetic they're imitating is a suitable replacement for the actual talent that went into it, but it isn't.
