I think down the line that would be true, but Facebook's willingness to burn literal billions of dollars at this point is basically the only thing carrying VR. Id love to see it split off in the future though.
I don't think the issue with VR at this point is so much technical than it is that nobody's yet been creative enough to make something truly unique with it.
I'm still a believer, but I suspect there are other non-VR technologies that either need to catch up or just figure out how to dovetail for VR to be anything other than a novelty.
