Affordable 3D Mapping for AR and Autonomy

I've never posted on Hacker News before, but since getting introduced to this community yesterday, I figured I would try contributing something.

I personally find the work Pixel8 is doing to make positionally accurate, high-definition 3D scanning possible to do with commodity smartphones thrilling. It's akin to making cutting-edge archaeological techniques accessible for everyone. And the stuff that will be built on top of these maps (autonomous vehicles delivering your pizza, AR games like Pokemon Go but much more interactive, insanely detailed asset inventories, etc.) are pretty exciting to think about, too.
