IT has been disrupting itself for six decades and there are more developers than ever, with high pay.

Have to temper expectations with fact that a generated video of a thing is also a recording of a simulation of the thing. For long video, you'd want everything from temporal consistency and emotional affect maintenance to conservation of energy, angular momentum and respecting this or that dynamics.

A bunch of fields would be simultaneously impacted. From computational physics to 3D animation (if you have a 3D renderer and video generator, you can compose both). While it's not completely unfounded to extrapolate that progress will be as fast as with everything prior, consequences would be a lot more profound while complexities are much compounded. I down weight accordingly even though I'd actually prefer to be wrong.

It's not about random short clips - imagine introducing a character like Mickey Mouse and reusing him everywhere with the same character - my guess is it's going to take a while until "transfer" like that will work reliably.

Dreambooth and Texual inversion is already here, and it's been just over a month since Stable Diffusion was released, so I'd bet on sooner rather than later.
