I think the difference is VR. At the moment, CGI is essentially a craft. You use a set of tricks, illusions, and hacks to deliver an immersive experience. Games like Doom show that when you get all these tricks right, the result is impressive. Unfortunately, like all hacks, they aren't robust. Most of them work on the assumption that the player won't look to closely at anything, or will only look at certain angles, or move through the game world at regular speeds. People who do CGI are already well aware that when you go into VR, a lot of the hacks just don't work. Often, to deliver a high-quality experience, you have to throw polygons at the problem. I'm pretty skeptical of this presentation - talking that much about optimization and performance makes me suspicious that their performance is terrible. However, ultimately, unless better hacks are devised, I think VR will be too much of a robustness test for the current model. In the short term, that will probably just result in some ugly graphics. In the long term, it'll put a lot of weight behind the drive to find better, less hacky solutions - and voxels are kinda first and foremost in that category.
