Quote from Homo Deus by Yuval Harari
Devices such as Amazon’s Kindle are able to collect data on their users while they are reading. Your Kindle can, for example, monitor which parts of a book you read quickly, and which slowly; on which page you took a break, and on which sentence you abandoned the book, never to pick it up again.
If Kindle is upgraded with face recognition and biometric sensors, it will know how each sentence you read influenced your heart rate and blood pressure. It will know what made you laugh, what made you sad and what made you angry. Soon, books will read you while you are reading them. And whereas you quickly forget most of what you read, Amazon will never forget a thing.
Such data will enable Amazon to choose books for you with uncanny precision. It will also enable Amazon to know exactly who you are, and how to turn you on and off.
Eventually we may reach a point when it will be impossible to disconnect from this all-knowing network even for a moment. Disconnection will mean death. If medical hopes are realised, future humans will incorporate into their bodies a host of biometric devices, bionic organs and nano-robots, which will monitor our health and defend us from infections, illnesses and damage.
Yet these devices will have to be online 24/ 7, both in order to be updated with the latest medical developments, and to protect them from the new plagues of cyberspace. Just as my home computer is constantly attacked by viruses, worms and Trojan horses, so will be my pacemaker, hearing aid and nanotech immune system. If I don’t update my body’s anti-virus program regularly, I will wake up one day to discover that the millions of nano-robots coursing through my veins are now controlled by a North Korean hacker.

If we are not careful the result might be an Orwellian police state that constantly monitors and controls not only all our actions, but even what happens inside our bodies and our brains. Just think what uses Stalin could have found for omnipresent biometric sensors – and what uses Putin might yet find for them.
