Introduction to Nexus: A History of Information Networks from the Stone Age to AI
Humans have been sharing stories from the stone age to AI. Yuval Noah Harari shows this journey in “Nexus: A History of Information Networks from the Stone Age to AI”. He talks about how we’ve shared information, from cave drawings to AI.
Early people used myths and religions to connect. The Bible was an early way to share messages, even if not always accurate. Then, the printing press, radio, and TV changed society, setting up for the digital age.
Now, AI changes how we share information like never before. It shapes our daily talks and changes the economy big time. For example, ChatGPT in 2022 changed how we talk online, through comments and posts on places like Facebook and Twitter.
A big fact from 2022 is that 30% of all Facebook and Twitter shares were from AI. This shows how technology is all over our chats. Companies use AI to get smarter and work better. By 2030, AI could make the world economy $15.7 trillion stronger. China and North America could get most of this, making the rich-poor gap bigger.
Harari points out how old ways of talking link to today’s tech mess. The story from the stone age to AI is not just about tech grow. It’s about how we always want to share, learn, and change.
The Foundation of Human Networks
Understanding “human networks” starts by looking at old ways people talked to each other. A long, long time ago, people used myths and stories to work together in big groups, not just with family. Historian Yuval Noah Harari tells us how important these stories were to make societies work.
Stories were not just for fun. They helped share knowledge and kept people working together. Early humans used symbols and cave paintings to share their thoughts and what happened to them. Moving from talking to writing changed how people worked together a lot.
Harari says myths helped people feel like they belonged together, had the same goals, and understood their place. Writing down laws, trading stuff, and keeping history helped big groups of people get along better. This shows how talking and writing changed human history.
When people started to organize in bigger groups, some got more power by keeping track of info. They made paperwork the same and made rules clearer. This made it easier to collect taxes and control people. The old ways of talking and writing helped build the big world we live in today. They show how we need each other to survive and do better.
The Rise of Written Information
Writing systems started a big change in how humans could keep and share info. Places like Mesopotamia and Egypt were first to write using clay and papyrus. This let people save knowledge in new ways, unlike talking could. It also helped make society and leadership much better.
Written info kept growing, leading to a huge moment in history: Gutenberg made the printing press in the 1440s. This changed how info reached people. Now, many could read things like the Bible. Knowledge was for everyone, not just a few.
Yuval Noah Harari talks in “Sapiens” about the printing press. It changed not just learning and faith but also society and politics. For example, “The Malleus Maleficarum” spread in the 1480s. It made witch hunts happen all over Europe. This shows how strong info sharing can be.
Truly, writing and the printing press changed what humans can do. These steps are key to understanding our journey. We’ve gone from ancient writers on tablets to fast info sharing today. This affects all parts of life now.

Inorganic Information Networks and AI
In the last 100,000 years, humans have made a lot of progress. We developed networks that changed a lot over time. Now, we’re moving to networks run by AI, a big change in history. Yuval Noah Harari believes AI can bring big advances or big problems.
In March 2016, something big happened. AlphaGo, an AI program, beat Lee Sedol in Go. This showed AI can do better than humans in hard tasks. Everyone around the world noticed, including experts and governments.
But Harari is worried about depending too much on AI networks. They can watch us closely, which is a risk to privacy. With AI watching, we have to think about who controls our data. Also, AI might change jobs a lot, taking over many professions.
AI’s fast growth will also change our society. Harari says we need new skills for future jobs. But, AI might also mess with democracy. Elections could be less meaningful because of surveillance.
To sum it up, shifting to AI networks is a big deal. It’s not just about tech. It’s about how we keep privacy, democracy, and jobs safe in this new AI era.
The Role of Misinformation and Disinformation
Misleading information has always been a problem, shaping how societies act. Historical Perspectives on Misleading Information shows us how lies were used to control people.
For example, during World War II, the Romanian Government took citizenship away through documents. This shows how information can be used as a weapon. Also, the witch-hunts in Europe tell us how believing in false information led to violence.
“Surveillance practices, evolving from ancient China and the Soviet secret police to modern mass data collection, highlight the increased power and reach of digital tools,” noted an historian from the Nexus research team.
Nowadays, digital platforms spread information quickly but also spread lies faster. Studies say that lies spread 70% faster than the truth on these platforms. Half of the people worry they can’t tell what’s true because of this.
AI brings new challenges. It can keep unfair biases going, like in facial recognition or job hiring. Experts say we need clear and fair systems to stop these problems. AI can make misleading stories that are hard to argue, making people trust less in those in power by 30%.
We must remember the lessons from Historical Perspectives on Misleading Information as AI grows. The danger of lies harming society shows we need strong rules. A recent poll showed over 75% of experts think these rules are very important for AI.
AI’s Transformative Impact on Modern Information Networks
AI is changing how we handle information today. Historian Yuval Noah Harari shows us that AI’s effects touch many parts of our lives. It changes how we get our information and affects society in big ways. In places with strict rules, like China, AI helps watch over people. China’s Social Credit System is an example. It checks what people do and say. Good behavior gets rewarded, and bad behavior gets punished. This shows AI’s big role in society.
In systems with strong control, AI helps leaders watch and manage people and resources better. China’s “Great Firewall” controls what information people can see. It makes the country seem stable while hiding any disagreement. This kind of control is not new. It reminds us of older times, like Stalin’s rule in the Soviet Union. But in free countries, using AI is more complex. They must make sure it’s fair, open, and can fix its mistakes. AI is already affecting how we vote and how we share healthcare.
Harari thinks if we’re not careful, AI may make the gap between different parts of the world bigger. He calls this the “Silicon Curtain,” similar to the Cold War. Countries now compete over who has the best technology. This race for the best AI shows a new kind of global challenge. As AI gets more mixed into our information networks, its power for good or bad gets bigger.
To end, AI’s big changes to our information handling call for careful steps. Making sure AI is used fairly and ethically is key as it changes our world. Putting human values first is very important. Leaders, tech experts, and all of us need to talk about how to use AI right. This way, AI can help us move forward together, not pull us apart.

Political and Social Implications of AI
AI changes our world in big and complex ways. Yuval Noah Harari talks about how wrong info has always been a problem. Now, AI is causing a huge change, bigger than any before.
Power is starting to move away from people to machines, says Harari. “for the first time in history, power is shifting away from humans and toward something else.” AI can make big decisions, like who gets a loan or where to send soldiers. When AI beat the world Go champion, it showed machines can outthink us.
Harari compares how lies work in different governments, whether open or hidden, it’s all based on make-believe. “All human political systems are based on fictions, but some admit it, and some do not,” he says, about truth in politics.
AI affects society too. It can twist information, making it hard for us to get the real story. This can make unfairness worse, as history shows.
But there’s hope. Companies like Amazon use feedback to fix problems. This helps fight the bad side of AI. Harari believes we need this to keep control and stay fair.
Harari’s book “Homo Deus” talks about how AI might change us. It can be good but also threatens freedom. We need to be careful with AI and how it’s used.
