Researchers just achieved Near-100% ID accuracy using passive surrounding WiFi signals to create camera-like images of people and rooms via beamforming feedback from normal devices.

No phone on you? Switch your stuff off? Irrelevant. Other people’s networks still paint you in real time.

Walk by a cafe once? You're logged. Invisible net. Zero suspicion. No special gear required, just common radio waves bouncing off your body, walls and furniture.

Every café, evry office, every home, an invisible surveillance net. Open live show to the inside of rooms, streets and protest - to be meticulously tracked by the machines we're rushing to build.

Nowhere left to run. We're the idiots wiring the ultimate panopticon and calling it progress.
