All good points! Even more recent than camcorders, the awkward-tech-thing is to record video or take pictures with an iPad, so it's not like there's no precedent.

I'd completely forgotten about Facebook using the depth information for 3D photos. Now I'm wondering if the 3D photos and videos in the Vision are like that, or have even more depth information by virtue of having multiple cameras. It hadn't occurred to me (until people suggested it, and it should've seemed obvious in retrospect!) that existing cameras could be used to record these photos or videos, because I just assumed that of course you needed multiple cameras with at least as much separation as a person's IPD. But a) you could do that by putting a camera on either end of an iPhone, and b) as you mention, it might not even be necessary if you've got LIDAR already getting enough depth info to build a 3D model.

Speaking of synergy: I've been working on an AR project for the past couple of years, and it's amazing how well AR Kit works on the iPhones, even though Apple hasn't ever seemed to tout it as a big deal. It's not just image tracking, but entire scene tracking -- you can just put a 3d object somewhere in the room, and it'll do a pretty remarkable job of staying put.
