I've been an avid Quest 2 user. There is nothing else like it. I use it for portable workouts and it does the job pretty well. Meta is years ahead of anyone else in this field.
But will this ever reach mainstream adoption? I think Zuck and others need to understand that the ask of putting a headset on is a pretty big one and is one of the biggest impediments, even if the stuff inside that headset can be pretty cool! I just don't see a path to that ever becoming normalized in our society or workplace.
I feel Zuck is letting his personal bias inform his decisions because he is an avid early adopter and is perhaps super comfy with VR headsets. I mean he bought Oculus in the first place !
I personally think stuff like VR/AR doesn't become truly mainstream until we hit a contact lenses level form factor. I know that sounds way out there but I don't see any other way. Getting to a sunglasses form factor will be a big win but still won't be enough to go mainstream, perhaps 25% of the way. And even that is easily 10 years away if not more.
If I was part of their innovation team, I'd buy another smaller company like Nreal Air that's innovating in he sunglasses display/AR space quite well and then try to marry VR/AR with that. If they can achieve that, they will get a big jump in adoption. It will require an external computation box, perhaps a smartphone sized one, but that's still an easier ask than putting a whole headset on.
