Who is the target market for this?
Young hip companies don't have anything to do with Facebook, that's their parents' social media. The people who use Facebook the most likely have zero interest in "VR meetings". Not sure anyone really does - how is that an improvement over Zoom other than not having to make your upper body and face presentable?
If they had done this 10 years ago I could have seen some Silicon Valley startups using this, or if we had covid-09. They are too late, this will disappear without a trace by next summer.
