If in the 1980s, during the height of the Cold War, you had predicted that in 30 years virtually everyone would voluntarily be wearing tracking devices that pinpointed their location 24 hours a day, and voluntarily carried recording devices which could at least in principle record everything they and anyone they talked to said, you'd be branded a conspiracy theorist or a believer in sheer science fiction.

Today it's no longer a paranoid fantasy but a reality, yet even those who aren't in denial about it are mostly not choosing to opt out of the surveillance.
