Any chance on expanding on what the critical blocking tech is?

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.
Because demand is too low, and prior attempts at hyping it up with marketing ended like google glass?
I do work in an engineering consultancy that did a dozen of VR/AR toys over the last 5 years.
Some of quite big brands around use our tech, and engineering, though NDAs, NDAs, NDAs...
There is no magic trick behind any of product on the market. Physics, and optics of AR/VR glasses is very simple, high school level simple. Just too many companies want to make add "smoke, and mirrors" into the optical scheme...
Making AR/VR goggles power efficient, and lightweight enough for daily use is possible even with current day tech. It's not much of a secret now that there is an IP blocker on a critical technology owned by Beijing University that shuts everything down.
Microsoft, Facebook, Apple experimenting with lasers now is all about them trying to work around that blocker.
