I have prosopagnosia. Glasses that could tell me the name of the person talking to me would be amazing. But not if I have to give big tech data about everyone around me
I try to explain it is a lot like the subway scenes from Pink Floyd's "The Wall". Everyone has the same distorted indistinguishable face.
Very likely I have lost a lot of "new friends" and business contacts from walking past not recognizing them.
But I'm not wearing something where the content might get viewed by a random person in Nigeria for "cataloging content".
