I can't really this guy too seriously when the bolded "kicker" to his story are citations to studies from 1989. Equipment and research from that time period had latency in the hundreds of milliseconds. (For context, modern studies (2009) show that 5ms latencies are imperceptible in HMDs [1]) I'd be interested to hear what vintage and what specs those $80K headsets really were. Knowing the specs of older $50-100K research HMDs, I have extreme doubts that resolution, latency, or tracking accuracy match today's consumer headsets even (most of the tech stemming from the billions and billions of dollars of investment spent on smartphone development from the past decade). When talking about depth perception, hyperbole like "THAT problem can’t be fixed by any known technological means" (in reference to focal/depth plane projection) is completely inaccurate, and contributes to the feeling of crochety old man ranting. There are multiple VRD and light field solutions being worked on to address the multi/vari-focus issue (my current favorite approach is the micro-lensed near-eye light field displays, although I suspect that barrier-based LFDs will be what gets adopted first). Vection is a big issue, but there's a huge amount of 1:1 motion experiences available, and based on personal/anecdotal experience, most people have no problem spending 15-30m in them w/o having strong adverse effects. Thousands of people have done the 10m+ the Oculus Connect and Vive Experience demos w/ very few issues. Based on that, I believe that for experiences w/o artificial vection, comfort is primarily a software problem at this point, not hardware. Personally, I'm pretty bullish on all the locomotion experiments going on (teleportation, re-orientation, redirection). I'm a bit less convinced on vehicle/cockpit vection w/o linked motion control, but the price is certainly not an issue for high-end military simulators and lots of enthusiasts are making DIY 6DOF simulators.
