Nexus looks through the long lens of human history to consider how the flow of information has brought us here. Taking us from the Stone Age through the canonisation of the Bible, the invention of print, the rise of mass media and the recent resurgence of populism, Yuval Noah Harari asks us to consider the complex relationship between information and truth, bureaucracy and mythology, wisdom and power. He explores how systems like the Roman Empire, the Catholic Church and the Soviet Union have wielded information to achieve their goals, for good and ill. And he addresses the urgent choices we face as non-human intelligence threatens our very existence.
