Why is everyone looking at VR in terms of what exists? VR is not gaming, though it shares many aspects of gaming. VR is not social, though it will overlap with a lot of how we use social today. It also won't be the Web, though, if it takes off, it will need to borrow the same open network-anyone-can-set-up-there-tent-where-they-want infrastructure.

But will Facebook be the company to make that happen? The great walled garden will turn into the great walled immersive world. If Facebook manages to pull that off we will all be poorer for it.
