It’s very difficult to not be truly unique if someone out there is purposefully tracking you as an individual.
And the neat part about that is... it used to be very expensive to do it. Now it blew right on through free, and into highly profitable. So it can be done to everyone everywhere at every moment.
No one knows how many people the Nazis employed to spy on the rest. Some estimates are like 1/4 of the population spied on the others! Today? We can put that to shame using only 0.01% or w/e of our population to spies on the rest. B/c that 0.01% has surveilance tools unimaginably powerful compared to anything the Nazis dreamed about.
There is a place in the world for targeted surveilance of bad people, mass murders, drug kingpins, w/e. You get a judge to sign off, and go to town. But dragnet surveilance of everyone at all times erodes the foundation of free societies.
