To add to my above- I have spent a lot of time researching AR glasses tech that would allow for this that could potentially be available even as old dev kits to buy, and the tech is out there in a much smaller form factor than what Meta is needing here to get them the full color, high res, 3d display. To just get floating text, all you need is a micro laser projector in the arm of the glasses pointed at a section of the lens that reflects and focuses the projection onto your retina, at a virtual focus so that it appears in front of you. Google bought a company that was making a dev kit of these a few years ago (I believe it was called North and the glasses were called Focals). But, as we know, google does this all the time and then kills shit. So I was happy at first because google said they were going to use this to do exactly what I describe above as their first killer app for the glasses. But then... nothing. Vuzix is another player in the game but with micro-led displays via waveguide instead, and they seem to actually be selling product, but at something like $800 it's just too much to try out just to do my own dev work for.
