Meta seems like there was a wall of post-it notes in Zuck's office with a bunch of ideas to stop FB from becoming MySpace and the dart he threw landed on this one.
My gut tells me that Meta is dead in the water but with the billions that FB have in their war chest I wouldn't bet against it completely, however, the fact it requires a headset, a massive source of friction, will restrict the audience.
I dunno... seems like Zuck is living in a fantasy world here.
