This is a good summary, thanks. And yeah, I only meant to speak to the argument in the comments over how many cycles we can "fit" in the next 20 years. I think a lot of VR's biggest hurdles for that time aren't dependent on processing power. Focus and resolution issues will side-step some of it (seriously, our eyes are terrible outside of their central focus region!) because there's simply no need to render everything flawlessly as on a TV. Beyond that, there are going to be all kinds of design hurdles. Right now, we have nausea-inducing roller coaster rides and people running into walls because we can't sync up the (already impressive) visual experience with inner-ear confusion and physical boundaries. Just working out what the most compelling designs are for our current VR tech is the work of years, and that's without doing it on the treadmill of ever-improving tech!
