Yes, but that shouldn't matter.
> most of the production spending is still using fancy optics and traditional production.
It used to be shot and physically spliced together celluloid, too.
Optics are punch card technology. The art, and indeed the end goal itself, is storytelling. The technology is just a means to an end. A grid of photons can be crafted and manipulated much easier with new techniques than by trying to put those photons in the correct places by hand. We're going to look back at optics and glass as the dinosaur age.
> And even for virtual production, the actors are still people
For now. Models can generate animated poses. This is moving faster than you're giving it credit.
(Even when robots replace us, people will still want to act - no question. The technology will still afford that. But just like ADR can now be model-based, so can posture correction.)
Your average ten year olds will be making their own Star Wars films by the end of the decade.
