Nexus
A Brief History of Information Networks from the Stone Age to AI
by Yuval Noah Harari
Brief overview
This book explores how human societies have used stories, documents, and organized networks to shape cooperation, from ancient myths to modern artificial intelligence. It shows how each new information technology reshapes politics and culture, often in unpredictable ways. Readers will discover how we went from telling campfire tales to relying on vast data systems, and why truth, bias, and power remain urgent questions in the age of AI.
Introduction
Imagine turning time back to an era when humans gathered around fires, sharing tales that bound them together. These stories, whether about gods or ancestral heroes, served as early threads stitching communities into cohesive groups. Over millennia, we developed more sophisticated ways of storing and sharing information, from clay tablets to the internet.
As societies grew, so did our reliance on structured networks that could coordinate armies, run economies, and define beliefs. The core aim was to harness the mass flow of information. But every technological leap came with unexpected consequences—from illusions that justified power to biases that spurred conflict.
Today, artificial intelligence stands poised to become an even more powerful force in determining truth, shaping trust, and guiding decisions that affect billions. The challenges of misinformation, flawed data, and unchecked authority show us that these networks need careful oversight.
In this summary, we’ll see how human groups move from small-scale myth-sharing to large-scale data-driven systems. Along the way, we’ll uncover how knowledge, belief, and control entangle—and why it’s vital to maintain self-correcting mechanisms in every era.
From Tribal Tales to Empires
Before writing, people relied on spoken myths to remember rules and forge deeper bonds. Hunter-gatherer communities shared stories that explained the world and clarified social duties. Even with limited group size, these tales motivated joint hunts or rituals, building trust vital for survival.
As agriculture spread, settlements ballooned in population. A few local leaders or chiefs tried to control resources, but oral storytelling alone no longer sufficed to coordinate far-flung lands. People needed new methods to track property, taxes, and alliances beyond immediate face-to-face encounters.
Empires like ancient Rome and China progressed precisely because they created new forms of documentation. Administrative scribes turned fleeting spoken decisions into permanent records, thereby unifying vast territories under a single authority. Yet these records often served rulers’ ambitions more than ordinary people.
Innovations in record-keeping led to grand civilizations, but each empire had to walk a fine line between harnessing data for the public good and using it to cement the power of an elite. This tension would continue for centuries, shaping how societies responded to truth and change.
