Apple is trying so hard to make these look like goggles you see through that just shows whatever you want wherever you want. So much they put the external display to show your eyes outside.
It's just a VR headset. AR is just really good pass-through, something most already have but isn't useful, mixed on the software side. You're still looking at screens. This isn't new tech, this is existing tech given the amount of development apple does. Just like everything else they've done.
Apple doesn't make new tech, they make existing tech nice.
