I think the issue is that if we know only one thing about you, that one thing is your label.

I see a policeman on TV, he's a 'cop'. Sure he may be a father, avid sci-fi junkie, and so on, but all I see is one dimension.

If Star Wars Kid cured cancer, we wouldn't forget about his light saber antics but we'd add that to our impression of him----now he's a nobel winning scientist, with an impressive intellect, who has saved potentially billions of lives..... oh and in his youth he used to geek out on Youtube.

True, something of that magnitude would probably change expectations. But what if you are just a good software developer or something like that?

The policeman example is interesting, what happens in a society where a policeman is trying to be taken seriously and discourage you from some activity you are doing but your glasses automatically recognise his face and say "hey, I see you are being harassed by the police, these naked pictures leaked by his ex-wife might be of use to you".

A more useful feature would be for the device to automatically stream video to an off-site location whenever it recognizes a policeman, badge, or vehicle.
