Show me some evidence, or even some compelling reasoning, for how something can make remote work more efficient, and I'll be all over it. If Meta's got some sort of doodad that will make it so that I can get all the benefits of in-person meetings from home, great, let's go, I'll pay to upgrade my team at work out of pocket.
But I don't see any sign of that here. You're saying that, if the headsets were easy to wear, everyone would use them, but I can't imagine why. How's this better than a laptop with a camera? I can read text more easily on the laptop. I can share documents more easily on the camera. I can see people's faces and emotions more clearly with the camera. This gets me nothing, and it does so at significant cost.
This appears to be a solution desperately searching for a problem, and remote meetings certainly have problems, but this doesn't seem to be able to solve any of them.
Sure, I'll be excited about this if I really need to collaboratively design the frame of a car with a team that's all working remotely. It'll work great for that. But you know how often my meetings would be greatly eased with a collaborative 3D space? Not often.
