I suspect that the current design of VR/AR is not likely to get cheap enough and light/small enough to catch on in a big way. Kind of seems like diminishing returns on headset improvements at this point.
If the price of leading edge VR price drops two orders of magnitude every 35 years or so, it's probably only going to be another 10-15 years for $200 headsets.
So it's not here yet, but will be soon.
