I said this in a previous thread and I'll repeat it here again.
Magic Leap[1] did it years ahead of them, and in my opinion better.
I mean - they're doing pass-through AR which is silly. There's all this work being done to emulate people and faces when they could just build lenses.
I feel like I'm taking crazy pills watch everyone get so hyped over this, because there's literally better devices already out on the mark. This is effectively a $3500 Oculus device. Like what the heck? I know it's just because Apple made it, but still. This is pretty weird to watch the reaction.
