I have a different take
The information is out there, we cannot rely forever on the inefficiency of an attacker.
Computers and their internet are making it easier to index and correlate this information.
Our location, gait and so on is constantly tracked by phone companies.
But everything else can be found in public by CCTV cameras, drones etc. They are able to literally know where you are at all times. They can analyze your gait, face, tag your car, and so on. Law enforcement can use wifi to see if you’re inside a building and find a good correlation between that and any video.
AI can predict when and where a network of dissidents will organize, and flag police to intercept (palantir is just one company that does this). It would be trivial for an AI-powered government to predict and defuse any uprising or organizing.
People have been outed by timing attacks (being in real-time chatrooms and having their internet cut to confirm it’s them). JK Rowling has been outed by analyzing her style.
Robots will be able to track down a human, outrun and and incapacitate them easily. Forget speeding tickets by cop. They’ll have drones spot the car from the sky, cameras by the road snap the car’s info. If it’s a criminal suspect, they can release little bots to roll up next to a car and puncture its tires to slow it down. Come and collect. No more high speed chases.
We need to let the public have access to this. We need encrypted CCTV video from cameras in college dorm tooms stored and decrypted when there is a need to solve eg a rape court case.
In some way this may also be helpful in the future for preserving alibis because video and audio can now be totally faked with deepfakes, and adversarial iteration will make it go past the uncanny valley into indistinguishability from real video. So the future will have immutable records with timestamps of everything. Where you were and when. Deal with it.
The genie is out of the bottle. More here:
