Yuval Noah Harari’s Nexus: A Brief History of Information Networks from the Stone Age to AI explores the role of information in shaping human civilisation and the transformative impact of artificial intelligence. Harari argues that throughout history, power has always been tied to control over information, but AI introduces a new and unprecedented shift—one where machines can autonomously process, create, and influence information without human oversight.

The book warns of AI’s ability to reshape economies, governance, and public discourse, raising ethical concerns about surveillance, misinformation, and the loss of human agency. Harari compares AI’s unchecked growth to The Sorcerer’s Apprentice, illustrating the dangers of unleashing forces we cannot control. He highlights how AI already makes critical decisions about finance, hiring, and justice, often without transparency.

A striking metaphor in Nexus is the pigeon, symbolising both peace and war, reflecting the dual nature of information—it can empower societies or be weaponised for control. Harari urges responsible AI governance to prevent manipulation and inequality, emphasising the need for ethical oversight. As we navigate an AI-driven future, Nexus serves as a crucial reminder of the power of information and the importance of safeguarding its integrity.
