> whether there's compelling use cases outside of that
Indeed, this is the billion dollar question. It's very clear there are compelling use cases but the really obvious ones are niche industrial uses, commercial applications etc. So the real question is compelling mass market use cases.
The two mass market ones that are apparent at the moment are fitness and virtual office spaces. Fitness is already well on the way, virtual office use is still tenuous and really needs hardware improvements to get off the ground. Those improvements look likely in the next generation of hardware so it's going to be an interesting 24 months to see whether it takes off or not.
The elephant in the room, as you point out, is that neither of these match Faceook's supposed aspiration to create a Metaverse. So I see Facebook/Meta's ultimate success here being dictated heavily by how fast they can get over that and target the real mass market use cases as their primary focus.
