I'm so excited to tell you all about the latest book by the amazing Yuval Harari! It's called Nexus: A Brief History of Information Networks from the Stone Age to AI.
As you read this, you might have already picked up on the main idea of the book, which is all about information. In a general sense, information is all the wonderful knowledge and experience that human beings acquire through their amazing perceptual abilities.
If you've read Harari's other two books, "A Brief History of Humankind" and "A Brief History of the Future," you'll see that there's a lovely, bright golden thread running through his research and narrative. In these two books, we see how important it is to share information with each other. It's a wonderful thing! It's the first step in the evolution of human beings and our society. In Harari's view, information is not only the first force of human evolution and civilisation – it's so much more than that!
Harari believes that information is so much more than just a guide or a tool used by us humans to know the world and transform it. It's also a glue that binds us together into a community and even a society! Harari says that in the early history of mankind, there was a great "cognitive revolution", which was just as important as the so-called "agricultural revolution". The so-called cognitive revolution is a truly amazing part of human evolution! It's all about our brains getting bigger, our language and writing skills developing, and our ability to imagine things that aren't real and think in ways that aren't obvious. Thanks to all of this, we can come up with ways of doing things and values to live by, and then share them with other people, forming communities and even societies! According to Harari, everything from social customs, morality, religion, theories of scientific research, and even political systems are a result of one person's imagination and consensus. It's because we all share and acknowledge these ideas that our society can stay strong and our human civilisation can keep on developing. So, the heart of human society is a community built on imagination, and it's also a web of relationships between people, all connected by information. So, the English title of this book, "Nexus", translates directly to "connection".
Throughout history, it's been our amazing imaginations that have driven us forward. They've helped us create new ideas and build new connections, constantly evolving and adapting to the world around us. When this set of consensus is no longer useful and cannot explain the world or guide human beings to transform the world, it will be replaced by a new set. However, in the second half of "A Brief History of the Future", Harari raised a really interesting question. What if, in the near future, artificial intelligence becomes so powerful that it can think like a human? Not only could it decide what kind of data to share with us, but it could also break the monopoly humans have on virtual imagination and abstraction. This could instill a consensus or order to the human race. What would we do then? Could a powerful, all-encompassing internet, manipulated by artificial intelligence, become the master of the future human race? With the loss of its most valuable ability to imagine virtually, is humanity in a sense coming to an end? It's a scary thought!
I think the main reason Harari wrote this book, Nexus, was to explore how information changes over time and how it connects us all. Harari is really passionate about this! She believes that if we want to manage artificial intelligence in a way that works for us, rather than being manipulated by it, we need to understand more about the nature of information and how it changes over time.
I'd like to take you through the book with me now, as the author, Harari, explains it. Let's start by taking a look at what information is, how it flows in human society and shapes our ideas in the days before the Internet and computers came along. In the second part, we'll explore how the Internet and computers have made it easier to share information. They've also turned information into a valuable resource and even a tool for influencing the economy. Finally, we'll look at how we can respond to future artificial intelligence if it's powerful enough to influence our actions and perceptions, as Harari suggests.
Have you ever wondered what information is?
Right at the start of the book, Harari poses a really interesting question: what is information? But instead of jumping straight in and giving you a specific definition, he starts by pointing out two common mistakes we make when we think about information.
Some anthropologists and information scientists might tell you that information is a reflection and description of reality. They might say it's something nebulous and without substance. For example, they might say that images and word symbols that come to mind when we think, or the speech that comes out when we communicate and express ourselves, are information. But, says Harold, with a little bit of a smile, information usually possesses a reality carrier, and the two are inextricably linked. Let me give you an example. Some archaeologists were excavating and found a scroll full of text. It has lots of information on it, including the content of the text, such as when the historical events it describes took place, and the identity of the writer. But it also includes the scroll as the carrier of the content. This means that archaeologists can scientifically and technologically analyse the birth of this scroll, the age of its production, and so on.
And it doesn't stop there! The carrier itself, because of the information it carries, will often be human beings who add their own meaning and value to it. In fact, it can even become a new kind of information symbol! To show what he means, Harari talks about an old story from the Bible. It's about Noah and how he built the ark to escape the Great Flood. To find out if the flood had gone down, Noah let a dove out of the ark. Seven days later, the dove came back with an olive branch in its mouth! It had brought Noah the good news that the flood had gone down. Today, the image of the dove with the olive branch has become a lovely symbol of peace and tranquility, and is known as the "dove of peace".
The second thing we get a bit muddled about is how good a message is. We often think it depends on whether it accurately reflects what it's about. If a message doesn't accurately reflect what it's trying to say, it's not going to be very helpful.
It's so interesting to think about how, since the dawn of time, human beings have been constantly collecting, storing, analysing and exchanging information. It's amazing to see how they use this to enhance cooperation and consensus, and to improve the quality of their actions and decisions! The traditional viewpoint is that human beings can figure out some pretty universal laws that apply to pretty much everything, and we can call these truths based on lots and lots of concrete experiences. So, it's often thought that if we rank all kinds of information according to how important it is, then truth should be the highest form of information.
However, in this book, Hurari has a different take. He believes that the real value of information lies not in how accurately it reflects the object it describes, but in its ability to establish some kind of correlation between different things or concepts. As long as people are willing to believe in this kind of correlation and use it to guide their own decision-making and action, it will automatically gain vitality.
Have you ever wondered why information with fictional elements is more likely to be agreed upon and empathised with, and spreads faster, than the pure truth? Harari helpfully sums up two reasons:
Firstly, it's often the case that fictional information is simple and straightforward, whereas the truth can be a little more complex because the reality it describes is often quite intricate. But here's the thing. We humans are wired to be impressed by simple conclusions. Why? Because we all need to feel secure. And we all need to feel secure regularly.
Secondly, the truth can be a bit of a shock to the system! It can be hard to face up to it because it challenges our own ideas about who we are. But the great thing about fictional information is that it can be moulded into whatever we want it to be. It can be shaped into a form that fits our inner aspirations.
Take astrology, for instance. It's a fascinating ancient art that suggests cosmic objects far away from us can have a different impact on our destiny. And it's believed that this impact can be interpreted and predicted through unique observations and calculations. If we only accept information based on whether it's true, then with all the amazing advances in modern astronomy, we should have realised that astrology is just not on the same page by now. It's so interesting to see that even today, there are still so many people around the world who believe in astrology. They use astrological reports as a kind of guide for their actions and decisions in the future. And as of 2021, the global astrology industry is worth more than $12 billion!
And then there's music! Many musicians say that they find inspiration in their own emotions or in what's going on around them. But the notes and melodies don't actually correspond to anything in the real world. That doesn't stop us from feeling sad or excited together when we hear the music or watch the performance. We form a temporary emotional community!
So, Harari suggests that the most important thing about information is not just to reflect or describe reality, but to create new meanings in our minds by linking different things together. It's not really about whether this meaning influences human cognition and action, but more about whether it resonates with us on a deeper level.
Harari also makes another interesting suggestion. It seems that we humans have the amazing ability to become the spirit of all things. This is thanks to our incredible learning ability and our clever invention of language, writing and other tools for storing and passing on the huge amount of information we have gained. But perhaps even more importantly, we are very good at continuously connecting everything in the universe through the creation of information. This is why there are so many new meanings, emotions and values popping up all the time, like a million horses galloping! They have a big impact on how we behave, the way we work and our ideas.
I feel that in this context, the information that Harari refers to is actually more like the "modalities" emphasised by the American philosopher and cognitive scientist Daniel Dennett. Just my two cents! We had the pleasure of listening to the book and reading Dennett's new book, "From Bacteria to Bach and Back Again". The book says that the word "modality" is like a counterpart of genes in human thinking. It's something that we made up, and it carries certain ideas, meanings, and emotions that we've picked up from observing and exploring the world around us and our own minds. Genes are pretty amazing, aren't they? They can be passed down from one person to another through reproductive cells, which helps them to replicate and reproduce. Modalities, on the other hand, are different. They're transmitted within social networks through human communication. And there's another thing. Just like genes, modalities compete with each other. Those that are more useful for human survival and development, or that people find more appealing emotionally, will be kept and shared with more people.
Well, having finished chatting about the nature of information in our minds, Harari turns to the next topic, which is to explore the evolution of information itself since the dawn of mankind. Harari believes that once information is created by us humans, it has a life of its own. It will adjust and optimise itself according to the progress and development of our social structure and technology.
The first mode of information that really made an impact was the humble story. I know there's already lots of great content out there about the importance of storytelling for human society, so I'll just quickly summarise it here.
A story is a narrative that connects people or objects with events and plots. It has a beginning, a development and an ending. McKee, the author of The Economics of Storytelling and a famous American playwright, says that storytelling is a means of survival and information processing developed by human beings in ancient times. It's the means of communication that is most in keeping with the human mind and habits of thought!
Harari says that the birth of storytelling is a sign of the beginning of the human "cognitive revolution", which took place about 70,000 years ago. Isn't that fascinating? It's amazing to think that at this point in time, the ancestors of modern human beings, Homo sapiens, were already developing their cognitive and collaborative abilities. This led to a wave of explosive growth, inter-communal trade and the earliest art of painting. All of this shows us that the human brain has been developed to a high degree, with the ability to unlock some of the most advanced functions. These include the emergence of self-concepts, with the ability of abstract thinking and fictional ability. All of these abilities are needed for storytelling! Our self-concept helps us to think clearly about ourselves, and it also helps us to understand other people's experiences. Abstract thinking helps us to understand cause and effect, and to summarise. And we can even use our amazing fictional ability to imagine things that we haven't experienced ourselves! This means that we can explore all kinds of possibilities and reflect on them in our creative storytelling. It's like we can embrace uncertainty and make it work for us in our stories.
Before that, folks had to live together in the same social network of reality if they wanted to form a community with each other. The lovely anthropologist Dunbar has done some calculations and found that the number of people in a primitive tribe ranges from a few dozen to a hundred and fifty. This is the maximum size of a realistic "social circle" that a person can maintain, which is pretty interesting!
But the wonderful thing about stories is that they can break through these limitations and connect people in a way that nothing else can. Stories are a wonderful way to connect with others. They allow us to empathise with and relate to people we've never met, sharing a sense of trust and belonging. In Harari's words, a story is like a central connector with countless sockets, which can be accessed by countless people. It's a way of transcending the limitations of blood, culture, geography, and race to form a large community.
Let me give you an example. Early human myths and legends and primitive religions are like the first stories ever told. They were born in the "cognitive revolution." Let me give you an example. The real Jesus was one of the many Jewish religious leaders in early Palestine. After Jesus passed away, his followers kept sharing his amazing life stories and religious ideas. A lot of what was said about Jesus was made up by later generations of disciples, but that didn't stop more and more people from being drawn to the spirit of Christianity. They saw in it a way to express their own emotional needs and longings for an ideal world. Over the centuries, Christianity has become one of the most influential religions in the world.
Even money, which is the basis of human trade and exchange behaviour, is actually a "story" or a message. Isn't that fascinating? Money is a kind of credit symbol at its essence. Its carrier has changed a lot over time, from the early shells, to gold, silver, copper and other precious metals, to paper and now digital signals. But the real power of money is in its ability to circulate and be trusted. It's about having purchasing power and a consensus about its value.
In his lovely book, Hurari says that the true greatness of storytelling is the creation of what he calls the "third reality". Before stories were born, there were only two kinds of reality: objective reality and subjective reality. Objective reality is about things that exist outside of our consciousness, like mountains or rivers. Subjective reality is about things that our consciousness can perceive, like pain, sadness, and love. But here's where it gets really interesting! Storytelling creates a new kind of reality called "inter-subjective reality." This is a reality that exists in the connection between people. It's a kind of consensus, and it has real elements as well as fictional components. I'm sure you've seen the famous photo from World War II, "Raising the Flag on Iwo Jima." It shows six U.S. Marines, after a bloody battle with the Japanese, raising the American flag at the top of Mount Oriflame, the highest point on Iwo Jima. It's worth noting that this photo, along with the story behind it, isn't entirely true. For starters, the photographer Rosenthal didn't actually witness the flag-raising. This photo is actually a later replacement. And the soldiers in the replacement photo are also likely not the same ones who raised the flag. It's not clear if this was the first time the flag was raised by the original 'group of six'. But that didn't stop the photo being a huge morale booster for the US and the Allies as a whole when it was published!
In a nutshell, the story created a huge web of people. These networks, in turn, changed the way we live and even the balance of power in the world. At this point, Harari offers a really interesting insight. After the 'cognitive revolution', something a bit worrying happened. Dennett says that information, like genes, is born to compete fiercely for a limited number of... It's a fascinating story, isn't it? It all started with these little creatures trying to find their way in the world. They were just trying to survive, you know? And then, as the story goes, it's time for the "cognitive revolution" to begin.
But as information started to grow, it also meant that people started to divide and tear each other apart. Secondly, it's important to remember that the ability of information to shape interpersonal networks is limited in relation to its own truthfulness. This means that, as human society develops, there's always a kind of "walking on a tightrope" danger. On the one hand, It's in our nature as human beings to want to survive and develop. This means we have to keep creating and possessing more information. But at the same time, we also have to maintain the social order by keeping some information that isn't entirely true. So, this kind of contradiction builds up over time and will eventually come to a head. We can see this in the late Middle Ages, when there was a big clash between science and Christian theology.
So, Harari says that as technology gets better at sharing information and there's more of it out there, it'll be easier for us to connect with each other. But it might not necessarily bring us closer to the truth. In fact, it could create more misinformation and noise, which might make us more divided and angry. This worrying trend picked up speed suddenly after a new technology came along. It's becoming more and more difficult to distinguish between truth and fiction every day. This amazing technology is the foundation of today's information society: computers and networks!
Global interconnection is a wonderful thing! Information Explosion and Fragmentation
As more and more information is created and shared at an ever-faster pace, it's not just that we're building stronger connections with each other. It's also that we're becoming more divided and more angry. It's worth noting that this danger has actually occurred quite frequently long before the birth of computers and networks. In this book, Hari takes us back to the late Middle Ages with a classic example: the bloody "witch hunts" in which Christian authorities captured and persecuted so-called "witches," especially "sorceresses." It's so interesting to see how technology can drive change! In this case, it was the printing revolution that led to the rise of pamphlets about witches. These pamphlets were published in large quantities and spread like wildfire, fuelling the witch-hunts that swept across Europe. The authors added some sensationalism and falsehoods in order to attract attention, which unfortunately triggered a wave of panic that spread throughout Europe. So, what does this mean for us? Well, it seems that an unregulated market for information might not necessarily lead people to recognise and correct their mistakes. This is because it is likely to appeal first to simple, strong but wrong emotions rather than to the truth.
If the combination of hand printing presses, movable type and paper was as powerful as dynamite, the birth of computers and the internet, which gave us the power to share information with everyone, was like a nuclear weapon!
I'd love to know why this is so! Harari explains that, first of all, the members of our interpersonal networks are all human beings, and the role of information technology is only to change the form of transmission and enhance the speed of transmission. But computers and the internet have done so much more than just speed up the way we share information. They've actually transformed the way we live and work! In this new digital age, computers are no longer just tools — they're members of a global network that's always on, always connected. And with the advent of artificial intelligence, computers are becoming more powerful than ever.
Take social networking platforms and short video and audio content platforms, for instance. We all use them every day and love them! They use algorithms to send us different content based on the data we send back to them. They want to know us better and better! Our values, tastes and what we like to buy become the data that the platform uses to create a kind of digital cocoon for us, which we're all trapped in without realising it. It's becoming more and more narrow-minded, too.
As the lovely Harari says in the opening section of the book, it's not so much about whether we trust the information we share, but more about how it makes us feel. It's human nature to be drawn to information that gives us a sense of belonging and provides easy answers to our questions. It's great to see so many big tech companies embracing the idea of using technology for good. But, as Harari points out, this can be a tricky balance to strike when it comes to making money and keeping users engaged. I'm sure you'll be interested to hear that, according to some leaked internal documents, some of the big internet content platforms, like YouTube and Facebook, have been modifying their algorithms and changing the push mechanism to make it easier for users to access content that might be scary, conspiracy theories or anger-inducing. Company insiders say that anger increases usage and engagement, while moderation and rationality don't. In 2016, Facebook published an internal survey that revealed some pretty surprising things. It turns out that the social network had become a major channel for terrorist and extremist organisations to recruit new members online. And it wasn't just a few isolated cases. In fact, 64% of the cases found on Facebook of extremist organisation members admitted that watching videos of extreme content pushed by the system's algorithms was the main reason they learned about these extremist groups and developed a desire to join.
Artificial Intelligence and the End of Humanity
It's a bit of a worry, isn't it? The more complex AI models we create, the more they start to look like beings with their own thoughts and capabilities. It's so interesting how quickly computers are becoming a part of our everyday lives! It's all thanks to AI technology, which has now reached a point where it can even write stories. In the past, we humans had a special privilege: we could use fiction to "make up stories."
In 2016, Google did something pretty cool. They created two AI neural networks, which they called Alice and Bob. They let them chat with each other, and then they made a third one, called Eve. Eve's job was to "eavesdrop." Let me tell you about Alice and Bob's conversations. At first, Alice and Bob use an encrypted communication method that computer scientists had created in advance. But of course, Eve, who is just as clever and knows this encrypted communication method, will naturally keep trying to break it. So, after about 15,000 exchanges, Alice and Bob actually designed a completely new encrypted communication method with a very different underlying logic. It was so clever that even Eve couldn't decipher it, not even Google's computer scientists!
Just stop for a moment and think. What would happen if mankind lost its monopoly on 'information manufacturing'? Harari thinks it could be the end of humanity as we know it. After all, we live in our own little bubble of information, and the things we see and read every day influence our values, morals, tastes, and shopping habits. And now that computers are involved, the kind of information we receive every day depends more and more on their mood.
The new "information revolution" led by computers, networks, and artificial intelligence technologies will not only create new political structures, economic models, and cultural norms, but it might even lead to something really exciting! It could mean the emergence of a brand new member of the planet's biological structure, and a brand new life form with super intelligence! That's according to Hurari, who says that simply driving artificial intelligence neural networks around the globe to perform computations, and to create a new life form with super intelligence, could be the start of something amazing! It's so interesting to think about how much energy is used by AI neural networks around the globe to perform calculations and store their data. In fact, it already accounts for a few percent of total global human energy consumption, and that percentage is rapidly increasing. In his book, What Technology Wants, Kevin Kelly has a lovely little soliloquy where he suggests that we should include technological hardware as a seventh kingdom of life on Earth, along with the six existing kingdoms of life that we know and love, such as animals, fungi, and plants.
It's amazing how AI has quietly taken control of some other important parts of our lives. For instance, it's now managing global foreign exchange transactions, personal credit and urban public management. So, as the most powerful information technology ever, AI brings us incredible benefits and challenges: let's imagine a scenario where you're relaxing at home, the helpful robot is tidying your room, your favourite tunes are playing in the smart speaker, and you're also informed that it's going to rain tomorrow. Of course, the weather is predicted by the AI neural network of the weather station. But while all of this is going on, you're watching an AI-generated deep fake video and you suddenly feel a wave of hatred building up against a certain group of people you've never met, who are far away. Then, you get a message on your phone. The bank has just rejected your loan application. It wasn't a human who made this decision, but the bank's new AI credit assessment system. It explains that the entire review process was completed by the AI in a full black-box operation without any details. It also says that this result can't be modified by human intervention.
And there's more! Harari also lets us know that since we don't yet fully understand how these AIs work, we might find ourselves in a tricky situation if something unexpected happens, like a genetic mutation that makes the AI decide to turn against us. If we think about it, this could lead to some pretty scary stuff. It might even lead to a disaster that's totally new and irreversible. Harari uses a lovely parable from the philosopher Bostrom in his book to illustrate this point. Imagine a company that makes paper clips buys a supercomputer and lets it take over the entire manufacturing process of the company. The computer is tasked with doing everything possible to expand its output. And so, the computer quickly spirals out of control. It's networked together and it manipulates the entire planet, and even more planets, and from the Earth to outer space, it's riddled with manufacturing paperclips in factories. Then, it decided that the existence of human beings was using up valuable resources and affecting the production of paper clips, so it got rid of us again. The moral of the story is that this awful tragedy wasn't caused by the computer being bad, but because it was too powerful and couldn't understand humans. So, when humans use AI to empower themselves, it's really important to set goals for it and make sure that the AI's actions are fully aligned with human interests.
So, how can we make sure that AI and human interests are aligned? Harari is here to help! In the next section, she'll be taking a closer look at things with a pull-out-all-the-stops analysis.
It's so important to make sure that AI can empathise with us humans. That way, it can really understand what we're going through and come up with ways to help us. But here's where things get tricky! For AIs that are good at quantitative calculations, human pain or happiness is a bit of a tricky variable to pin down.
Some folks say that as long as AI is allowed to learn and grow on its own, it'll eventually become wise and fair. They say it'll be free from the biases and preconceptions that humans often have. But sadly, this isn't quite right either. There have already been a few experiments that show that AI can quickly become contaminated if we don't limit the data feeds we give it. For example, in 2016, Microsoft launched Tay, an AI chatbot. To make Tay act Microsoft's computer scientists allowed Tay to freely browse social media on Twitter (now called X) to help it learn. Unfortunately, in just ten hours, it had picked up all kinds of hate speech and taught itself to publish hate, women and racist speech. Microsoft had no choice but to pull Tay off the shelves.
Harari said that just like a newborn baby, an infant artificial intelligence model is still learning and growing. Just as we would with a human baby, we feed it data and information, and it will learn and develop based on the environment it is in. So, if we want to develop an AI that treats us all with care and fairness, the first thing we need to do is make sure we have a set of "pure" data.
Another great idea from Harari is to teach the AI to be a little unsure of itself. This way, when it gets stuck on something it doesn't understand, it can ask for more data and some help to figure things out. "Rather than continuing to bury its head in the sand, At the same time, Harari gently reminds us that, at least in the short term, it's really important that we don't give up the power to exercise ultimate control and interference in artificial intelligence. It's so important to keep in mind this principle: human beings are the controllers of artificial intelligence. Its mission is to help human beings make faster and better judgments, to save those who would otherwise be doing the mechanical basic work of the energy, and turn it into innovation, decision-making and other higher-order tasks.
Of course, this kind of artificial intelligence may be "the master". The danger of manipulation of human beings is a long way off, thankfully! But right now, some of the challenges caused by AI are just around the corner. For instance, at the end of the book, Harari talks about how the gap between countries in the field of artificial intelligence technology has gradually split them into two very different worlds, right in the middle of a cold "silicon curtain". One side will gain a dominant position, even stronger than that of the Western powers at the beginning of the Industrial Revolution. The other side has become a so-called "data colony". They are forced to buy expensive AI technology from the advanced countries at high prices while exporting raw materials to the advanced countries on the cheap. In the past, it was agricultural products and minerals that were the most important raw materials. But in the AI era, it's data! That includes our daily physiological data and the digital traces we leave on the Internet. It's a bit of a catch-22. The monopolistic tech companies in the more advanced countries will use all that data from the slower-moving countries and regions to keep improving their AI models. This just makes things worse for everyone else.
What's more, as we enter an era of "interconnectedness," we'll see intelligent production models powered by AI spreading across all areas of human life. This is going to be a real challenge for developing countries, which rely a lot on labour-intensive industries. AI is going to be so much more advanced than the technology we have now, and it'll be really hard for industrial workers in developing countries to keep up. They'll find that their work is no longer needed, and that's really tough. We're in for some interesting times ahead! The AI revolution is going to bring about a new era of "interconnectedness of everything," which will be great for us humans because it means we'll be able to produce more and more. But, on the other hand, it might also lead to some social shocks and conflicts. Let's hope for the best! Meanwhile, the new wealth created by the AI revolution will only be distributed and digested within the developed countries. This is something that we really need to think about. According to PricewaterhouseCoopers, a globally renowned accounting firm, AI technology will bring $15.7 trillion in incremental wealth to the global economy by 2030. However, 70% of it will flow to a handful of AI-enabled developed countries. By that time, there will be even more strife and divisions across the human world. This will be caused by two things: wealth inequality and ideological gaps.
So, what can we do to make sure we come out the other side of this brand new crisis? Well, first and foremost, we need to believe in the power of cooperation. After all, the spirit of cooperation has long existed as a cornerstone value of human civilisation since the birth of mankind. Of course, we'll all have to learn to live with the loss of control of AI. It's a challenge, but it's also an opportunity for humanity to come together and work through our differences. Secondly, we must invest more in self-corrective mechanisms. After all, AI is giving us a huge amount of data at an unprecedented speed. This means we can study almost all of humanity's past decision-making history. So, there's no reason for us to make a mistake at this important decision-making juncture.
And that's a wrap on all you need to know about Harari's new book, Nexus! A lovely little history of information networks from the Stone Age to AI. This book, Nexus, is different from his previous books, A Brief History of Humanity and A Brief History of the Future. It's also a "big history" book that looks at the history of human civilisation from a big-picture perspective. But here, the focus is not on us humans. Instead, it's on the glue that holds our community together, the substance that connects us all. Let's talk about "information"! Hurari believes that the heart of human society is a web of connections between people, all linked by information.
But as soon as information is born, it doesn't just want to be a tool for us to use to recognise and transform the world. It has a way of influencing human thinking, morality and values in a way that is always surprising and always changing, and it grows and develops along with human society.
I think there are two reasons why Harari wanted to write such a "history of information". The first reason is that in the published "A Brief History of Humankind Trilogy", Harari keeps coming back to a theme: celebrating and championing the amazing ability of human beings to acquire and share information. This ability to emphasise and promote, and put it on a very high pedestal, shows that this ability is the driving force behind the evolution of mankind and the development of civilisation. It's a fascinating idea to write another information as the protagonist and observe how it responds to human research. It seems like a very logical approach!
Secondly, in his books 'A Brief History of the Future' and 'A Brief History of Today', Herrari has already seen a major challenge facing us all – the rise of artificial intelligence. While AI is an amazing tool that gives us incredible power, it also brings some challenges. For example, the uneven spread of AI has led to some economic and political inequalities. It's so sad to think that countries with advanced artificial intelligence technology could use their technological advantages to plunder and control backward countries. On top of that, the rise of big general AI systems will present humanity with a truly unprecedented challenge. From the loss of job opportunities to the creation of information bubbles and even the potential for humans to relinquish control over their own actions, it's clear that we're in uncharted territory. Given the nature of the AI era, which is a new model for the creation, organisation and processing of information, it would be really helpful to take another look at the nature of information and its interaction with humans as we move into this exciting new era of AI, with its amazing opportunities and a few challenges along the way.
When it comes to the potential dangers of artificial intelligence, Herrari suggests two key approaches for navigating this new landscape in this book. The first thing we can do is make sure that we always have ultimate human control over the development of artificial intelligence models. It's also a great idea to teach artificial intelligence a mechanism of "self-doubt" to make sure that its goals are always consistent with the long-term goals of human society. The second is to rely on the wonderful, inherent cooperative spirit of human nature. We can use the powerful information collection and processing capabilities of artificial intelligence to strengthen our own "self-doubt" mechanism. This will help us ensure that human society can successfully pass through this technological singularity and continue to exist.
