Nexus — Chapter 6: Computers vs Printing Presses and How It Changes You Book Summary

Computers didn’t just speed up the printing press—they changed who gets to speak and decide. In Chapter 6 of Yuval Noah Harari’s “Nexus: A Brief History of Information Networks from the Stone Age to AI,” we explore how computers enter our networks as active agents, not passive tools, and why that shift reshapes attention, choice, and power. You’ll see how broadcast became feedback loops, why personalization is leverage, and how opaque, high-speed decisions demand new habits of self-correction. This episode stays true to the chapter’s ideas while making them practical for your day.


What you’ll learn: the core difference between transmission and agency; how algorithms “move first”; where personalization helps and harms; and simple ways to keep yourself in the loop. If this helped, answer in the comments: Where did a system “decide for you” this week—and did it feel like help or pressure? Then tap the next episode on always-on networks to continue the journey, and share this chapter with one friend who keeps asking why their feed feels different today.
