"I can't believe this has to be said (again), but cyberpunk was meant as a warning, not a business plan. It turns out that you need very few identifiers to make a guess about who a person standing in front of a billboard is, especially when you can suck data out of their phones.

"But it feels less creepy once you learn that these technologies don't have to rely on a camera to see where you are and what you're doing. Instead, they use radar.
