Sidenote: is he writing equations comically large on the blackboard for a reason?
VR instead of AR is a dealbreaker for me though- I want AR virtual monitors that overlay the displays on my actual vision. Even VR which uses a camera to pass through to the display isn't really what I want.
My ideal hardware would just be a "dumb" AR display with wide FOV and an HDMI input that just overlays the video data onto my normal vision.
From what I understand a big challenge is the wide FOV though, but I don't know enough about optics to really understand why this is the case.

The problem with AR is a basic technical one: you can't use a transparent lens to paint black pixels over white light. That's why Apple, despite being desperate to make the "Apple Glasses", has basically abandoned AR entirely in favor of VR-but-the-video-passthrough-is-so-good-it-feels-like-AR design, and I would expect most other companies working on AR devices to follow suit.
Well, yeah, he probably can't see them properly otherwise. Remember how grandma always used to tell you you'd ruin your eyesight by sitting too close to the TV?
