Every time I see phrases like this I just cringe. As someone who spent a ton of time in the gamedev/3D UI space I've yet to see anything about VR that points to be being successful in anything other than small markets. I think there are some amazing applications in architecture and gaming but I really don't see something you have to strap to you face making the mainstream in a meaningful way.
I really hope this doesn't dilute Servo's effort too much because they've been doing awesome stuff lately.
