Very interesting!

For someone with no knowledge about AR hardware, how is this different (from the perspective of the end user) than a traditional hololens style display?

That display type can be made bright enough to be outdoor visible while still keeping power consumption on sane levels.

The biggest problem of all waveguide systems is that they are freaking inefficient, with optics consuming 50-90%+ of all light.

And it is the same problem with pretty much all complex optical systems in AR/VR glasses.

This is why I am a proponent of using mirror optics in this application.

I wondered why google glass was canned, and I wondered if there was worries a bout liability for eyesight problems. I can imagine poorly matched AR could damage your eyes over time, in a way I suspect monitors currently do.
