> Virtually all the innovation in VR was made by Valve, the only innovation Facebook has added is inside out tracking.
That hasn't been true for a long while. Having a room-scale VR system back in 2016 certainly made Valve look quite a bit ahead of Oculus's "Rift is a sitting experience, have an Xbox controller" disaster.
But these days Oculus is far ahead, they are constantly adding new features (AR, hand tracking, wireless, standalone, 2D app integration, etc), while SteamVR is still mostly the same as it was back in 2016. At the moment SteamVR is barely even usable and full of bugs (resolution and input settings regularly disappear).
That's not to say that Oculus is the only one innovating, Microsoft's WMR Portal was a great attempt at bringing the Desktop into VR and they were the first ones with 6DOF tracking in a standalone headset. Some of the AR pass-through stuff, that Quest2 has just added, could be done on Daydream years ago.
But Daydream is dead, WMR seems to be on life support and SteamVR isn't getting any improvements either, all while Facebook went full throttle and is pumping out new VR features every few months. The only one that might have a chance at competing with Facebook's VR effort at this point is Sony with PSVR2 and maybe Apple, but their VR doesn't seem to not be aiming at the mass market.
