Nexus: A Brief History of Information Networks from the Stone Age to AI
How information networks have shaped human history and will shape our future
"Information is the tie that binds together complex systems."
— Yuval Noah Harari
My Review
Harari traces how information networks - from myths to algorithms - shape human cooperation. The concept of information as the organizing force of society parallels biological information flow in organisms and ecosystems.
Why It Matters
Information flow is central to both biological and social systems. Harari's analysis illuminates how communication networks shape collective behavior.
Key Ideas
- Information networks enable large-scale cooperation
- Each information technology changes social structure
- AI represents a fundamentally new type of information network
- Information can be true or false, but networks shape behavior regardless
How It Connects to This Framework
Book 5 (Communication & Signaling) and the information flow concepts throughout.
