Can you elaborate on “photonic override”? Googling that phrase pretty much just returns more HN comments and tweets by you :)

A hardware/software proxy that governs all photons you see.

This is desirable?

Desirable or not is subjective, but what's not as subjective is the liklihood of this technology stack arriving and becoming popular, which seems very likely/guaranteed at this point.

it does seem likely to arrive but whether it becomes popular more difficult to predict as it's conditioned on the sway of public opinion, which seems heterogeneous regarding AR/VR

Certainly for someone with defective default hardware ;)

I certainly see the utility there!

Look into “diminished reality” - the ability to block things out that would be a distraction, for instance.
