Magic Leap One Teardown
No matter what you think of Magic Leap generally, they did some amazing engineering here and I think that's worth appreciating. The stacked waveguide model is a great hack around the varifocal plane (accommodation) problem, but to make it work in a form factor that isn't gargatuan was a feat. Yes, it's only two planes, but it's a step forward.<p>Not to mention that it runs on batteries and is a fully integrated development environment - you gotta hand it to them that this was an engineering feat.
