I would argue Valve is the main driver of VR in terms of actual software + hardware + platform building. Facebook is just the biggest spender on VR right now.
> Who would actually use this?
Which is funny to me, because I can instantly think of over a dozen use cases for this stuff -- if Facebook was never involved. Use it for training, especially on-site training, use it for conferencing, use it for 3D visualization (basically half of the Hololens demos cross over)
But with Facebook owning it, the value prop of Oculus Quest is zero. It's no longer a hardware or software platform, it's a console, effectively no different than a Nintendo Switch or a PlayStation. Doesn't matter if the Quest was the best thing ever invented, no one reading Hacker News could deliver any products or solutions on it without Facebook owning/controlling it, so there's no reason for anyone to try.
