"Humans are now hackable" - Yuval Harari

"Whoever accumulates enough data about us might come to rule our lives. In the past, nobody had enough biological knowledge and enough computing power to hack people. Even if the KGB followed you around all day, they did not know what you were feeling and thinking. In the future, by combining our increasing biological knowledge with advanced artificial intelligence, external systems could know you better than you know yourself. Such systems could then control and manipulate people with unprecedented efficiency. And it is easiest to manipulate people who believe that their opinions and choices reflect their own free will. We should come to terms with the fact that humans are now hackable."  - Yuval Noah Harari, the Israeli author of Sapiens (2014), Homo Deus (2015), 21 Lessons for the 21st Century (2018)
