All Meta has to do is wait a couple of months or a year for Google to inevitably lose interest in XR and abandon their current project. Easy peasy.
As much as I'd love to see Meta get fucked in any, even the tiniest, capacity, I don't think they have much to worry about.
At present all of these augmented reality pipe dreams are halfassed solutions looking for problems. Here in reality, nobody cares. We just want to play VR games and watch VR porn. The other stuff is just annoying noise from the boardroom.
