I read this post hoping it would articulate the challenges of VR at a high level in an innovative way. After a promising start it turns out only to cover the problems that oculus has addressed — which all deal with the headset. The other problems that remain either unaddressed or poorly addressed aren't even discussed, ie motion tracking and motion in general (walking around), gesture and pose tracking, facial capture, force feedback, and eventually things like true spatial sound. Let's not even discuss olfactory capture and synthesis or temperature or breezes or wetness. Yes the optics and latency issues are interesting, but Carmack has actually discussed this on stage on several occasions.
