With a few notable exceptions (James Cameron) the film industry is largely unconcerned with "possibility." I think this is often why there is such a big misunderstanding from tech folks about how movies are made, since tech is very feature and tool driven whereas filmmaking is very much process-driven.

The Odyssey was shot on IMAX cameras half the size of a car that weighed 400lbs. It's easy to call that out as being ridiculous, surely a much smaller camera system could have achieved 99% the same results, etc. but that totally misses the point. Nolan could have shot it on anything he wanted, and he chose the less convenient way, because that is his process. If he was forced to use a more reasonable camera, it would not have been a Christopher Nolan film.

Sure, I'm down with that mix of generation + animation + mocap workflow. But at some point, people will going to look around at all the equipment, the people in mocap suits, the thousands of hours of generation and the millions of dollars of compute, and just wonder...wouldn't it be easier to just film someone with a real camera?
