Exactly what I was thinking. Will probably make current NV technology look ridiculously clunky.

I look at this way, 20-25 years ago nobody knew about electronic controlled auto darkening lenses for welding helmets, nice bit of hi-tech there that is common as heck now days.

First one I bought was over $100, now you can buy them for under $30.

Expecting NV to follow the same path, more complicated than fast electronic auto darkening, but doable.
