But we still don't have such a display tech or do we? I've never heard something like that. Probably someone can invent such tech within a decade. But seeing it in a consumer product takes time. So it's safe to assume that it won't happened within a decade if we don't even have such tech today. Especially in this context of investment.

That's not a VR glass. It's AR. They are completely different. For full VR, the display must be completely opaque. The side must be sealed to block environment. It's impossible to make it with a normal glasses shape with current tech and I don't think we can make it in a near future.

I don't need full VR, I just need a screen for a computer.

I'd love to be able to get some work done with just my glasses and maybe a Bluetooth keyboard ( this would be optional since finger tracker would also work )
