What's the display tech?

There's a link above with much more details: https://www.theverge.com/24253908/meta-orion-ar-glasses-demo...

  [The display] features Micro LED projectors inside the frame that beam graphics in front of your eyes via waveguides in the lenses. These lenses are made of silicon carbide, not plastic or glass. Meta picked silicon carbide for its durability, light weight, and ultrahigh index of refraction, which allows light beamed in from the projectors to fill more of your vision.
This 2022 paper seems like a good explainer of the tech, def download the PDF for the Figures: https://www.nature.com/articles/s41598-022-09680-1

  Through careful dispersion control in the excited propagation and diffraction modes, we design and implement our high-resolution full-color prototype, via the combination of analytical–numerical simulations, nanofabrication and device measurements... Our MOE waveguide utilizes only a single glass layer for the whole RGB spectrum, reducing unwanted diffraction and with higher efficiency. Our single-layer implementation also brings compactness and lightweight operation, while simplifying the MOE fabrication and yield.
Sooo this layman is reading it as "used fancy ML workflows to fabricate extremely precise hologram guides." Pretty damn impressive and exciting! It's a good day/year/millennium to be nerd, no doubt about it.

This is cool from a technical standpoint, but ultimately just feels like another gimmick. This feels like it's doing stuff that I could do faster or better (and definitely, more safely) on a computer or phone. I don't personally see the appeal of hands-free as a paradigm in most cases. Do we really want people talking on and looking at Zoom as they walk around the office? Or as they drive? Or as they are out shopping…

I can see this being extremely useful, especially if the person on the other can see what you're looking at. Interactive remote troubleshooting!

No goofier than someone talking through their airpods.

Wow these look huge, I was expecting it from the comments but it still managed to surpass my expectations. I wonder if they managed to squeeze a battery in it and that's why it's so thick. Assuming it's light enough to not cause pain after some extended use it's a huge step up from the Quest series (and other VR headsets that cover your entire head pretty much!) and a completely different class of product compared to…

100g, has a battery, but still a power puck

I also see ESPN and YouTube, so yeah... this thing better detect when you're moving at speed and disable video apps. People already do that using mobile phones. With glasses there is at least some visibility of things in front of you.

You're assuming people look out front and are paying attention to the "background" of whatever they're watching with their glasses.

Earlier quoted context omitted.

> Imagine if Meta decided to run facial recognition on-device and upload the results to their advertising services More like when they decide to do that. They want to capture and extrapolate any and all data possible from every possible source.

Oh, I am sure they'll try. The sales pitch is way too enticing for them to ignore. Imagine you're in a brick and mortar wireless store shopping for a new cell plan. A Meta user walks by, and you get caught in a frame. A facial recognition scan quickly links you to your shadow profile, and an image recognition model identifies that you are phone shopping. Meta knows who you are and pings your current carrier who quick…

> Oh, I am sure they'll try.

They won't just try, they'll simply do it, by default, in the absence of proactive action preventing it.

Honestly, people used to say the same thing about Bluetooth hands-free devices years ago, and now no one even bats an eye when someone talks using AirPods.
