First, that's not the same technique and it's not being used for the same purpose.

Second, Hollywood doesn't care about that problem. They will take the best application of the technique, and they don't care if they have to apply a few manual touchups on the result. As long as there is one way of using the system to do the sort of thing they showed in the sample, it won't matter to them that they can't embed a full video game into the neural network itself. They only care about the happy path of the tech.

Someone's probably already starting the company now to use this in special effects, or putting someone on research in an existing company.

Hmm, I wasn't trying to nay-say anything here. I mostly agree with your original comment.

See also how in the Gan Theft Auto they are sort-of getting the light reflection for free without having to explicitly teach the network about that parts of physics.
