Surveillance of the Future – Yuval Noah Harari

„Imagine North Korea in twenty years, when everyone must wear a biometric wristband that monitors your blood pressure, heart rate, and brain activity around the clock. You hear a speech from the great leader on the radio and they know what you really feel. You can clap your hands and smile, but if you are angry, they know you will be in the gulag tomorrow.

And if we allow the emergence of such total surveillance regimes, do not think that the rich and powerful will be safe in places like Davos.“
