Information is not truth. That’s the big, uncomfortable gut-punch at the heart of Nexus by Yuval Noah Harari. For years, we’ve been fed this optimistic Silicon Valley bedtime story that if we just connect everyone and flood the world with data, wisdom will somehow emerge like magic. It didn't. Instead, we got QAnon, deepfakes, and a loneliness epidemic that’s rotting our social fabric from the inside out.
Harari isn't just writing another history book here. He’s sounding a massive, high-decibel alarm.

Think about it. We have more information at our fingertips than a medieval king or a Renaissance scholar could dream of, yet we seem more confused than ever. If information was the same thing as truth, we’d be living in a utopia. We aren't. Nexus by Yuval Noah Harari argues that information is actually a tool for connection, but those connections are often built on delusions, lies, and bureaucratic nightmares.
The Silicon Paradox: Why More Data Means Less Reality
We’ve been living under a "naive view" of information. This is the idea that more data leads to more knowledge, which leads to better decisions. Harari tears this apart. He points out that the most successful information systems in history weren't actually good at finding the truth; they were good at keeping people in line.
Take the Roman Inquisition. Or the Soviet Union under Stalin. These were massive information networks. They collected files, names, and "facts." But were they seeking the truth? Absolutely not. They were seeking order. They were seeking power.
In Nexus by Yuval Noah Harari, he makes a chilling comparison between these old-school bureaucracies and our current algorithmic overlords. The scary part? Algorithms don't even have the "human" weaknesses that sometimes allowed people to slip through the cracks of the KGB. An algorithm doesn't get tired. It doesn't feel guilty. It just optimizes for engagement, and engagement is almost always fueled by anger, fear, and division.
Computers vs. Paper: What Changed?
Historically, if a king wanted to tax every person in his kingdom, he needed a literal army of scribes. Those scribes were human. They could be bribed. They could lose files. They could feel pity. The "information technology" of the time—paper and ink—was limited.
Today, the "Nexus" is digital. It’s silicon.
When an AI at a bank decides you aren't creditworthy, it doesn't give you a reason you can argue with. It just processes a billion data points and spits out a "No." We are moving from a world where humans use tools to a world where the tools are starting to use us. Harari calls AI an "alien intelligence," not artificial intelligence. It doesn't think like us. It doesn't care about our myths of democracy or human rights unless we figure out how to hard-code those values into it—which, honestly, we haven't done yet.
The Myth of Self-Correcting Networks
One of the most annoying tropes in tech circles is that the "marketplace of ideas" will eventually filter out the lies. Harari is basically calling BS on that. He argues that lies have a massive competitive advantage over the truth.
The truth is complicated. It’s boring. It requires nuance and "on the one hand" type of thinking. A lie? A lie can be shiny, simple, and perfectly designed to make you feel like a hero or a victim. In the battle for your attention, the truth is fighting with one hand tied behind its back.
In Nexus by Yuval Noah Harari, he looks at how the printing press—often hailed as the harbinger of the Enlightenment—actually led to a century of religious wars and witch hunts first. We forget that the most popular books after the invention of the press weren't scientific journals. They were manuals on how to identify and burn witches, like the Malleus Maleficarum.
We are in that "witch hunt" phase of the internet right now.
The End of Human History?
This sounds dramatic. It is dramatic. Harari suggests that history is the product of human stories. We agree on things like "money is valuable" or "this border exists," and that creates our reality. But what happens when the stories are no longer being written by humans?

When AI starts creating its own culture—writing its own music, its own code, its own political manifestos—human history as we know it might end. Not because we all die in a Terminator-style war, but because we lose control of the narrative. We become characters in a story written by an entity that doesn't share our biological needs.
- AI isn't a tool; it's an agent.
- Bureaucracies are the first "non-biological" entities to rule the world.
- Democracy relies on conversation, and AI might kill the possibility of genuine human dialogue.
Can We Fix the Nexus?
It's not all doom and gloom, though it definitely feels that way when you're 300 pages into the book. Harari does offer a path, but it's not a "one weird trick" solution. It requires a fundamental shift in how we build and regulate technology.
Basically, we need "soft" institutions that can check the power of "hard" algorithms.
In the past, we developed things like professional journalism, peer-reviewed science, and independent courts to verify information. These are slow. They are expensive. And they are currently being bypassed by social media platforms that want to move fast and break things. Well, they broke the truth.
To survive the world described in Nexus by Yuval Noah Harari, we have to stop treating tech companies like neutral pipes. They are editors. They are publishers. And they need to be held accountable for the "information pollution" they pump into our brains.
Why You Should Actually Care
You might think, "I'm just a person checking my phone, how does this affect me?"
It affects your ability to know what's real. It affects your mental health. If the algorithms are tuned to keep you scrolling by making you angry at your neighbor, you're going to be angry at your neighbor regardless of whether they actually did anything wrong. We are losing our agency.

Harari’s point is that we are the first generation to live with an "alien" in our pockets. Every time you open an app, that alien is learning how to manipulate you better. It’s not a fair fight.
Real-World Action: Reclaiming Your Mind
The book doesn't give you a checklist, but the implications are clear. If you want to survive the "Nexus," you have to change your relationship with information.
First, stop equating "more information" with "better informed." Usually, it's the opposite. The more news you consume in real-time, the less you actually understand the big picture. Deep work and long-form reading are the only ways to build a "firewall" in your brain.
Second, we need to demand accountability. We have building codes to make sure our houses don't fall down. We have FDA regulations to make sure our food isn't poison. Why don't we have "information codes" to ensure the algorithms we interact with aren't toxic?
- Reduce Frequency: Turn off the firehose. Check the news once a day, not once a minute.
- Verify Sources: If a piece of info makes you feel an intense surge of rage, it was probably designed to do that. Check it.
- Support Human Institutions: Pay for journalism. Support libraries. These are the "slow" information networks that actually value truth over clicks.
The challenge of the 21st century isn't going to be "getting" information. It’s going to be surviving it. Harari’s work is a map for that survival. It’s not a comfortable map, but it’s a necessary one. We are currently building a world that might not have a place for human wisdom unless we start prioritizing the "truth" over the "network."
Nexus by Yuval Noah Harari serves as a final warning: the network is growing, and it doesn't care about you. It’s time we started caring about the network.
Actionable Insights for the Digital Age
To apply the lessons from Harari’s latest work, consider these immediate shifts in your digital life:
- Audit Your Information Diet: Identify which platforms trigger "outage-response" loops and limit them to 15 minutes a day. Use tools that block feeds while allowing messaging.
- Prioritize Institutional Trust: Move away from "influencer" news and back toward organizations with a legal and professional stake in accuracy. Look for "Corrections" pages as a sign of health, not failure.
- Foster Local Connection: Silicon networks thrive on global abstraction. Physical, local communities—where you have to look someone in the eye—are the strongest defense against algorithmic radicalization.
- Demand Algorithmic Transparency: Support legislation that requires companies to disclose why a certain post was promoted to you. We need to know the "ingredients" of our digital meal.
- Practice Intellectual Humility: Acknowledge that the information nexus is designed to make you feel "right." If you never see information that challenges your core beliefs, you are likely trapped in a digital silo.
