Have you used any optical see-through HMDs? There's heaps, and they all have no problem displaying text. If you look at the spec sheet for the BT-300 for example [0] you'll see "Virtual screen size: 80" support (virtual viewing distance 5m)", or in other words you need to focus your eyes five meters away to see the display sharply, at which point it will appear to take up 80in of diagonal space in the real world (don't know why they mixed the units like this though). I'm pretty sure most people could read text off a 720p 80" screen 5m away. As for not making things dark, yes that's true. You can of course tint the glasses or use an extra layer to darken the outside world, or you can really crank the brightness causes the user's iris to contract creating the impression of higher contrast in the dark regions. Best option is to combine the approaches with a camera observing the environment, which can even be done on a per-pixel basis as in the paper I helped write [1] As for power/performance, it's all a matter of desired form factor. If you don't mind a cable to an arm or hip attached android device, you can have everything you need right now. Alternatively there's the Hololens style huge headset. But if you want slimline glasses yes you'll be waiting a few years. A lot a people are bearish on the future of AR and I can appreciate that viewpoint, but the arguments you've brought for it are at best half true and I hope readers don't see this and think any of these problems are unsolvable (or indeed, haven't already been solved) [0] https://tech.moverio.epson.com/en/bt-300/
