VR needs a killer app.
The problem is, Zuck thinks it's going to be essentially VRChat, but that won't be it.
It won't be any sort of virtual office either, as the resolution still isn't good enough. Also, I can't imagine someone that does most of their work using a keyboard would actually want to do their work in VR, especially if doing anything in VR still requires a controller.
There are a lot of really good games, but VR gaming is still very niche, even among people that play a lot of games.
