People say this all time, but I'm unconvinced. Your AR glasses can have two layers: * a transparent-or-black layer, whose only point is to block out the real

  Nope, I thought so too, but you can't. When the transparent-or-black layer activates, you end up with a blurry blob of black, not a sharp one. That means the best you can do is sort of muddy the image, not block it. It's the same reason you can't see scratches in glasses -- it gets blurred because your eyes' focal plane is in the distance. Or more precisely: You could do this, but it's probably not going to have the results you wanted. The effect has a good chance of being too distracting to be practical. But it's hard to know without trying it.

    Good analogy w/r/t scratches in glass ... but if that's a solvable problem for what you want to show (the additive layer), it seems like it should also be a solvable problem for the subtractive layer (?)

      It might be interesting to get a pair of glasses, put some black tape on the lenses and see what it might look like in practice. You could get some partially transparent tape to simulate what AR would end up doing. It seems like an experiment worth doing. If you put your finger up to your eye and close the other, then focus on your laptop screen, you can see the blurry edge of your finger interfere with whatever you're looking at. But that's opaque -- it's hard to know what a partially-transparent blob might look like, or how much of an impact it'd have.
