I don't think VR will have a big impact for the next 5-10 years.The article has a tone of fear or bemusement rather than criticism. Imagine a dude in some lost Amazonian tribe seeing a mirror and his own reflection for the first time. Could be that kind of thing.
FOIP will be great for the rollplayers and scripted Youtube video mob but otherwise I suspect it will be relatively little used unless it takes off because it helps you look around the cockpit... I still say you'll need a lot of light for the average webcam to be able to make it work properly though.
And as @Zull Reicher points out, VR will negate it, because if you are wearing a VR headset that covers half your face, a webcam is going to pick up shit-all face movements, so it seems its a feature that is disabled by another feature that the kind of people who would use the feature will be wanting to use unless they can account for that... Can they account for that?
It'll be a battle between VR and FOIP as to which comes out on top, if either, but it's nice to actually have the options.
too expensive
yet not enough (useful) applications
also last time i had a VR on i got the thing called motion sickness (might be me but i'm definitly not the only one)
also i agree that you will need enough light to use it. There is a reason why faceware sells this as a "desktop kit" (2500$)
But we will see how it really turns out (probably at citizencon)
