“Striking original . . . A historian whose arguments operate on the scale of millennia has managed to capture the zeitgeist perfectly.”—The Economist
“This deeply important book comes at a critical time as we all think through the implications of AI and automated content production. . . . Masterful and provocative.”—Mustafa Suleyman, author of The Coming Wave
For the last 100,000 years, we Sapiens have accumulated enormous power. But despite allour discoveries, inventions, and conquests, we now find ourselves in an existential crisis. The world is on the verge of ecological collapse. Misinformation abounds. And we are rushing headlong into the age of AI—a new information network that threatens to annihilate us. For all that we have accomplished, why are we so self-destructive?
Nexus looks through the long lens of human history to consider how the flow of information has shaped us, and our world. Taking us from the Stone Age, through the canonization of the Bible, early modern witch-hunts, Stalinism, Nazism, and the resurgence of populism today, Yuval Noah Harari asks us to consider the complex relationship between information and truth, bureaucracy and mythology, wisdom and power. He explores how different societies and political systems throughout history have wielded information to achieve their goals, for good and ill. And he addresses the urgent choices we face as non-human intelligence threatens our very existence.
Information is not the raw material of truth; neither is it a mere weapon. Nexus explores the hopeful middle ground between these extremes, and in doing so, rediscovers our shared humanity.

作者简介
文摘
What Is Information?
It is always tricky to define fundamental concepts. Since they are the basis for everything that follows, they themselves seem to lack any basis of their own. Physicists have a hard time defining matter and energy, biologists have a hard time defining life, and philosophers have a hard time defining reality.
Information is increasingly seen by many philosophers and biologists, and even by some physicists, as the most basic building block of reality, more elementary than matter and energy. No wonder that there are many disputes about how to define information, and how it is related to the evolution of life or to basic ideas in physics such as entropy, the laws of thermodynamics, and the quantum uncertainty principle. This book will make no attempt to resolve—or even explain—these disputes, nor will it offer a universal definition of information applicable to physics, biology, and all other fields of knowledge. Since it is a work of history, which studies the past and future development of human societies, it will focus on the definition and role of information in history.
In everyday usage, “information” is associated with human-made symbols like spoken or written words. Consider, for example, the story of Cher Ami and the Lost Battalion. In October 1918, when the American Expeditionary Forces was fighting to liberate northern France from the Germans, a battalion of more than five hundred American soldiers was trapped behind enemy lines. American artillery, which was trying to provide them with cover fire, misidentified their location and dropped the barrage directly on them. The battalion’s commander, Major Charles Whittlesey, urgently needed to inform headquarters of his true location, but no runner could break through the German line. According to several accounts, as a last resort Whittlesey turned to Cher Ami, an army carrier pigeon. On a tiny piece of paper, Whittlesey wrote, “We are along the road paralell [sic] 276.4. Our artillery is dropping a barrage directly on us. For heaven’s sake stop it.” The paper was inserted into a canister on Cher Ami’s right leg, and the bird was released into the air. One of the battalion’s soldiers, Private John Nell, recalled years later, “We knew without a doubt this was our last chance. If that one lonely, scared pigeon failed to find its loft, our fate was sealed.”
Witnesses later described how Cher Ami flew into heavy German fire. A shell exploded directly below the bird, killing five men and severely injuring the pigeon. A splinter tore through Cher Ami’s chest, and his right leg was left hanging by a tendon. But he got through. The wounded pigeon flew the forty kilometers to division headquarters in about forty-five minutes, with the canister containing the crucial message attached to the remnant of his right leg. Though there is some controversy about the exact details, it is clear that the American artillery adjusted its barrage, and an American counterattack rescued the Lost Battalion. Cher Ami was tended by army medics, sent to the United States as a hero, and became the subject of numerous articles, short stories, children’s books, poems, and even movies. The pigeon had no idea what information he was conveying, but the symbols inked on the piece of paper he carried helped save hundreds of men from death and captivity.
Information, however, does not have to consist of human-made symbols. According to the biblical myth of the Flood, Noah learned that the water had finally receded because the pigeon he sent out from the ark returned with an olive branch in her mouth. Then God set a rainbow in the clouds as a heavenly record of his promise never to flood the earth again. Pigeons, olive branches, and rainbows have since become iconic symbols of peace and tolerance. Objects that are even more remote than rainbows can also be information. For astronomers the shape and movement of galaxies constitute crucial information about the history of the universe. For navigators the North Star indicates which way is north. For astrologers the stars are a cosmic script, conveying information about the future of individual humans and entire societies.
Of course, defining something as “information” is a matter of perspective. An astronomer or astrologer might view the Libra constellation as “information,” but these distant stars are far more than just a notice board for human observers. There might be an alien civilization up there, totally oblivious to the information we glean from their home and to the stories we tell about it. Similarly, a piece of paper marked with ink splotches can be crucial information for an army unit, or dinner for a family of termites. Any object can be information—or not. This makes it difficult to define what information is.
The ambivalence of information has played an important role in the annals of military espionage, when spies needed to communicate information surreptitiously. During World War I, northern France was not the only major battleground. From 1915 to 1918 the British and Ottoman Empires fought for control of the Middle East. After repulsing an Ottoman attack on the Sinai Peninsula and the Suez Canal, the British in turn invaded the Ottoman Empire, but were held at bay until October 1917 by a fortified Ottoman line stretching from Beersheba to Gaza. British attempts to break through were repulsed at the First Battle of Gaza (March 26, 1917) and the Second Battle of Gaza (April 17–19, 1917). Meanwhile, pro-British Jews living in Palestine set up a spy network code-named NILI to inform the British about Ottoman troop movements. One method they developed to communicate with their British operators involved window shutters. Sarah Aaronsohn, a NILI commander, had a house overlooking the Mediterranean. She signaled British ships by closing or opening a particular shutter, according to a predetermined code. Numerous people, including Ottoman soldiers, could obviously see the shutter, but nobody other than NILI agents and their British operators understood it was vital military information. So, when is a shutter just a shutter, and when is it information?
The Ottomans eventually caught the NILI spy ring due in part to a strange mishap. In addition to shutters, NILI used carrier pigeons to convey coded messages. On September 3, 1917, one of the pigeons diverted off course and landed in—of all places—the house of an Ottoman officer. The officer found the coded message but couldn’t decipher it. Nevertheless, the pigeon itself was crucial information. Its existence indicated to the Ottomans that a spy ring was operating under their noses. As Marshall McLuhan might have put it, the pigeon was the message. NILI agents learned about the capture of the pigeon and immediately killed and buried all the remaining birds they had, because the mere possession of carrier pigeons was now incriminating information. But the massacre of the pigeons did not save NILI. Within a month the spy network was uncovered, several of its members were executed, and Sarah Aaronsohn committed suicide to avoid divulging NILI’s secrets under torture. When is a pigeon just a pigeon, and when is it information?
Clearly, then, information cannot be defined as specific types of material objects. Any object—a star, a shutter, a pigeon—can be information in the right context. So exactly what context defines such objects as “information”? The naive view of information argues that objects are defined as information in the context of truth seeking. Something is information if people use it to try to discover the truth. This view links the concept of information with the concept of truth and assumes that the main role of information is to represent reality. There is a reality “out there,” and information is something that represents that reality and that we can therefore use to learn about reality. For example, the information NILI provided the British was meant to represent the reality of Ottoman troop movements. If the Ottomans massed ten thousand soldiers in Gaza—the centerpiece of their defenses—a piece of paper with symbols representing “ten thousand” and “Gaza” was important information that could help the British win the battle. If, on the other hand, there were actually twenty thousand Ottoman troops in Gaza, that piece of paper did not represent reality accurately, and could lead the British to make a disastrous military mistake.
Put another way, the naive view argues that information is an attempt to represent reality, and when this attempt succeeds, we call it truth. While this book takes many issues with the naive view, it agrees that truth is an accurate representation of reality. But this book also holds that most information is not an attempt to represent reality and that what defines information is something entirely different. Most information in human society, and indeed in other biological and physical systems, does not represent anything.
I want to spend a little longer on this complex and crucial argument, because it constitutes the theoretical basis of the book.

In many ways, it is a book about politics, although the author never names names or talks in terms of blue and red. And his canvas is global and spans history. He does, however, talk about democracy, populism, totalitarianism, and such, terms that are being bandied about a lot in the US this election year. And that, I suspect, is why the reviews of the book vary so widely. We are a polarized nation and want to inject politics into just about everything.
Harari, however, is not a politician or political commentator. He is an historian who, of course, has not defined that history. His job is to spot the patterns. And in this case the pattern has a political implication. “Democracy and dictatorship are typically discussed as contrasting political and ethical systems. This chapter seeks to shift the terms of the discussion, by surveying the history of democracy and dictatorship as contrasting types of information networks.”
Which ultimately, of course, brings us to AI. The author correctly notes that AI is different from all prior information networks (e.g., printing, the telegraph, the Internet, the pre-modern church, etc.) in that it is the first network capable of acting independently of humans. And, as a result, it deserves special consideration, both for its opportunity and its menace.
Adding a bit of gravity and urgency to the matter, Harari notes: “The main argument of this book is that humankind gains enormous power by building large networks of cooperation, but the way these networks are built predisposes us to use that power unwisely. Our problem, therefore, is a network problem.”
Harari, among many other prominent voices, as a result, argues that we must manage the future application of AI. I agree. Our tech leaders, unfortunately, have shown themselves to be as independent of oversight as AI itself. And given the enormous amounts of capital that AI will undoubtedly unleash, my personal fear is that Silicon Valley, at Wall Street’s urging, will unleash AI before there is any public consensus on its application. After all, that is what they have done at every step of the digital revolution. They routinely release powerful new products that must almost immediately be updated to fix flaws and security oversights in their design. The earliest pioneers of the internet, as but one example, now readily admit that they did not foresee the degree to which it could be abused by malevolent actors. With AI, however, we may not get the chance to address the problems in retrospect.
As part of its mission, the book also offers a plethora of insights into several important underlying currents of thought and conviction important to current culture. Some of my favorite quotes:
“But power isn’t wisdom…”
“The naïve view [of information] thinks that disagreements about values turn out on closer inspection to be the fault of either the lack of information or deliberate disinformation.”
“History isn’t the study of the past; it is the study of change.”
“However, democracy doesn’t mean majority rule; rather, it means freedom and equality for all.”
“It is particularly crucial to remember that elections are not a method for discovering truth. Rather, they are a method for maintaining order by adjudicating between people’s conflicting desires.”
“…information isn’t truth.”
In the end, I believe it is an author’s job, with few exceptions, not to tell us what to believe, but to make us think. And with this book, in addition to his many others, this author has done just that. I do believe, therefore, that this book is worth every reader’s time. You won’t agree with everything he says. I didn’t, either. And it is true that the higher you take the camera the simpler the landscape looks, to the point of causing you to make erroneous conclusions about what you see. Not all patterns have meaning. Sometimes they are just patterns.
In this work, he expands on key premises from Sapiens, particularly the idea that imagination is humanity's superpower. As the (not misattributed) Einstein quote goes, "Imagination is more important than knowledge. Knowledge is limited; imagination encircles the world." This ability to imagine and create shared fictions is what has allowed Homo sapiens to build complex societies, foster large-scale cooperation, and achieve feats no other species-not even other great apes-have accomplished.
While animals like ants or bees cooperate in large groups, they do so within rigid, biologically determined roles. Humans, however, form alliances and organizations based on ideas untethered from biology. This imaginative flexibility enabled Homo Sapiens to outcompete other hominins like Neanderthals and Durisovans and dominate the planet. (Although Homo Erectus had been on Earth for 2 million years!)
Harari argues that everything humans create is, at its core, a fiction. His distinction between "order" (fiction or constructed reality) and "truth" (raw, chaotic reality) underscores how humans impose structure on an indifferent world. Shared fictions— from Fairies, Santa Clause, Easter Bunny to Companies, Corporations, Enterprises or political systems, religious beliefs, and economic frameworks-are not objectively real but derive their power from collective belief. These narratives allow societies to thrive, whether through trade, infrastructure, or even war.
His concept of "inter-subjective realities" captures this phenomenon: ideas that exist only because many people believe in them. Nations, for instance, are not physically delineated-they exist because we collectively agree on their boundaries. Money has no intrinsic value beyond the faith we place in it. These shared myths are what enable large-scale cooperation and societal complexity.
Yuval highlights the naive misconception about information often touted by the tech industry and mainstream society: the belief that more information inherently leads to innovation, progress, and that the truth will always prevail. The printing press is frequently cited as a transformative invention, but what’s often overlooked is that one of its most popular outputs was the Malleus Maleficarum, a witch-hunting manual that contributed to the deaths of tens of thousands of innocent people across Europe. Ironically, during the same period, Copernicus’ groundbreaking book—which shifted the paradigm from the geocentric theory (Earth at the center of the universe) to the heliocentric model (the Sun at the center)—was largely ignored by the public. Why? Because truth is often dull, while conspiracy theories are exciting.
This dynamic should sound familiar. Decades ago, many feared that governments and mainstream media were brainwashing the public with negativity. Unbeknownst still to many in the public humans naturally have a negative bias. Today, with the democratization of media through the internet, negativity and conspiracy theories have only proliferated. Echo chambers, clickbait, and sensationalist content dominate the digital space, amplifying modern conspiracies like the Area 51 raid, Hollywood and oligarchic sex rings, alien shape-shifting elites, flat Earth theories, and satanic baby-eating worshippers.
Harari draws a parallel between this phenomenon and the impact of the printing press. Before its advent, witches were not universally viewed as evil, even by the church. But with the spread of printed conspiracies, authoritarian and totalitarian regimes thrived on the chaos these narratives created—just as they do today. Harari reminds us that truth is inherently chaotic, unexciting, and often overshadowed by more captivating fictions.
The history of Judaism and Christianity, particularly the formation of the Torah and the Bible, was so fascinating—it opened up so much that I didn’t know. It was stimulating, to say the least. Shifting gears, I want to dive into my counterarguments about AI, which I believe is a natural part of human evolution. Suggesting we slow down AI’s development feels as unrealistic as expecting humanity to abolish nuclear weapons or replace capitalism outright—these things, unfortunately, aren’t happening.
While AI can present information in persuasive ways, individuals still have the agency to question and verify sources. The democratization of education and increased digital literacy can act as strong defenses against manipulation. Even Harari, who warns of AI propaganda, emphasizes the power of education. By prioritizing media literacy, we can effectively counteract many of AI’s potential risks. Manipulation is nothing new; it’s been around for centuries, from biased news to propaganda. AI might scale and speed up this issue, but societies have historically adapted through safeguards like fact-checking platforms, transparency initiatives, and ethical AI frameworks.
The concern about inequality is valid, but AI also has the potential to level the playing field. Open-source technologies, community-driven projects, and global collaboration can help ensure AI’s benefits are more evenly distributed. Affordable AI systems are already improving healthcare, education, and infrastructure in underdeveloped regions. Throughout history, fears about new technologies have been met with proactive solutions. For example, the Industrial Revolution initially led to significant inequality, but measures like antitrust laws, unions, and public funding eventually balanced the scales. Similarly, policies such as AI taxation, universal basic income, and global governance initiatives could prevent power and resources from becoming overly concentrated.
On the issue of trust, advances in AI detection tools are progressing rapidly. Algorithms to spot deepfakes, verify content authenticity, and ensure traceability through technologies like blockchain are already underway. Humans have always found ways to adapt to new challenges in distinguishing truth from falsehood. The invention of photography and video sparked similar fears of manipulation, yet we developed forensic analysis and journalistic standards to maintain trust. The same will likely happen with AI-generated content.
As with past technological revolutions, while some jobs may be lost, entirely new industries and roles will emerge. The rise of the internet, for example, gave us careers in web development, digital marketing, and e-commerce—none of which existed before. Similarly, AI will create demand in fields like ethical oversight, system maintenance, and human-AI collaboration. Rather than clinging to outdated economic views of work, societies could shift focus to more meaningful, creative, and community-driven pursuits. Shorter workweeks, universal basic income, and subsidized retraining programs could smooth the transition, making AI a tool for enhancing human purpose rather than threatening it.
While authoritarian regimes could misuse AI for oppression, the same tools can also empower democratic movements. AI can help activists organize, expose corruption, and spread counter-narratives effectively. Decentralized AI technologies could ensure that no single regime monopolizes these tools. Additionally, international treaties and regulations—similar to those for nuclear weapons or climate change—could establish ethical norms for AI use. Democratic nations and organizations have the opportunity to lead the charge in enforcing these standards.
Harari’s warnings about AI illuminate genuine dangers, but his arguments sometimes feel overly deterministic and dystopian, underestimating humanity’s adaptability and resilience. Yes, the challenges posed by AI are real, but they are far from insurmountable. With the right education, regulation, and global collaboration, AI can be harnessed as a force for progress rather than something to fear. Harari’s critiques are invaluable for sparking dialogue, but they should be balanced with optimism and proactive solutions.

I, myself, am learning more and more about Artificial Intelligence and to be honest I would consider this a core work if you are looking to understand what A.I. is and where it could go. The depth of knowledge that the author consumed in writing this is staggering and his organization and referencing of those works is done masterfully.
I was intrigued by just about everything in this work and here are some tidbits just minimally referenced:
- Referring to the difference between Intelligence and Consciousness. An obvious comparison but I liked how he laid it out, I sort of gave it a variation though. He referred to an example of Intelligence as the means to be able to bring followers and subscribers to your channel to which I immediately thought, whereas conscience is how you feel about doing what was necessary to bring those followers to your channel.
- The social credit system environment. He made a good point of if you have that in place in your society, say it was in the context of social credit for a religion. If someone gets max scores how do you know if the person did so because they truly believe in the religion or they just know how to play the game?
- Finally, self-correction as what is needed to be in place to save us from A.I. getting away from humanity (my interpretation). Yes, for when there is no self-correction (as he brings up in the book) things can get away and go too far sometimes too quickly.
Nexus is a true masterwork in my mind. I will read over and study this book. I have made note of many of the reference books and plan to get/read a number of them as well. More than 5 stars.
