This book is well researched and written like the other books by the author that I have read。The subtitle is a bit misleading as the author covers more than a brief history of information networks。 The most interesting part to me was how the development of Artificial Intelligence can easily go astray without the proper instructions on what to achieve。 Harari spends time demonstrating how it can wrong and leaving the discussion of the positives to AI enthusiasts。 Overall， interesting and thought This book is well researched and written like the other books by the author that I have read。The subtitle is a bit misleading as the author covers more than a brief history of information networks。 The most interesting part to me was how the development of Artificial Intelligence can easily go astray without the proper instructions on what to achieve。 Harari spends time demonstrating how it can wrong and leaving the discussion of the positives to AI enthusiasts。 Overall， interesting and thought provoking。I received a free Kindle copy of this book courtesy of Net Galley and the publisher with the understanding that I would post a review on Net Galley， Goodreads， Amazon and my nonfiction book review blog。 。。。more

Knowing from Harari that humans connect through stories， one day we were going to ask how those stories spread。 So here we are， at the shift in the nexus - maybe， better， the locus - of communication from human networks to computer networks unmediated by people。 Per now classic Harari， he asks and answers that question with a sweeping history then pushed forward into the future。

I received an advanced reader’s edition through Goodreads with the expectation that I would post an honest review of the book。 I was generally impressed with its breadth， depth， and accessibility。 The author brings the expertise of an old school polymath to the work。 He’s able to fruitfully integrate philosophy， history， religion， anthropology， science and technology into a coherent narrative of the role of information in human history。 There are times when the author unnecessarily ambles around I received an advanced reader’s edition through Goodreads with the expectation that I would post an honest review of the book。 I was generally impressed with its breadth， depth， and accessibility。 The author brings the expertise of an old school polymath to the work。 He’s able to fruitfully integrate philosophy， history， religion， anthropology， science and technology into a coherent narrative of the role of information in human history。 There are times when the author unnecessarily ambles around a point rather than just making it - like at the beginning when he spends pages defining what information isn’t but then eventually buries his definition of what it is。 He also makes a very sudden turn into AI and stays there for much of the book。 The book would have also benefited from more roadmapping to help the reader better understand the journey and where they were on it。 But ultimately the author’s points about how information serves to connect more than to represent， the consequences thot come from inabilities to correct mistakes in those connections， and the dangers we face from those dynamics in the age of AI， are deeply insightful。 A compelling read for any student of history， current affairs， and/or the human condition。 。。。more

OverviewNexus is Yuval Noah Harari's first major book in six years。 The book's subtitle—A Brief History of Information Networks from the Stone Age to AI—is both overly ambitious and highly misleading。 For a book ostensibly about information networks， there is no discussion of information theory—nor even a mention of Claude Shannon。 Those hoping for a proper history of information should look elsewhere to a book such as James Gleick's The Information。What we get instead is essentially an updated OverviewNexus is Yuval Noah Harari's first major book in six years。 The book's subtitle—A Brief History of Information Networks from the Stone Age to AI—is both overly ambitious and highly misleading。 For a book ostensibly about information networks， there is no discussion of information theory—nor even a mention of Claude Shannon。 Those hoping for a proper history of information should look elsewhere to a book such as James Gleick's The Information。What we get instead is essentially an updated synthesis of Harari's first two books， Sapiens and Homo Deus。 Sapiens developed the thesis that humans became the dominant species on earth not due to superior intelligence but due to our ability to create shared stories that enable us to collaborate on a far greater scale than any other species。 The book's concluding chapter raised the question of just how AI would impact the future development of humanity， a discussion that was expanded in the sequel Homo Deus。 What Nexus does is examine how subsequent generations of information technology， from orality and writing to the telegraph and the internet， have shaped the contours of human societies—making， breaking， and reforming the ways in which we interact with each other。 This culminates in yet another discussion of the present and future of AI。Since so much of this information is recycled from his prior books and is discussed pretty much everywhere these days， I'll restrict my analysis to the few points that I consider most notable。 As it will become clear， these insights all have something in common， revealing the shortcomings of Harari's approach。Information As a Form of CurrencyEach day billions of us conduct numerous transactions with the tech giants， but one could never guess that from our bank accounts， because hardly any money is moving。 We get information from the tech giants， and we pay them with information。 As more transactions follow this information-for-information model， the information economy grows at the expense of the money economy， until the very concept of money becomes questionable。 Classical economics has a problem。 By focusing almost exclusively on money and financial assets as a measure of value， it systematically discounts the importance of non-monetary exchange。 More recent economic analyses of slavery and unpaid domestic work have helped to fill in some of the gaps， but of particular importance to our digital age are the economic effects of the exchange of digital information。 As Harari notes， more and more transactions involve an exchange of information rather than money， and neither our economic nor our legal systems are prepared to account for or limit the excesses of informational wealth or digital bribes。 Left unchecked， big tech companies can exercise data colonialism， defining the terms of digital existence across borders。 For this reason， some scholars have even argued that countries should recognize big tech companies diplomatically so that they may better negotiate terms for their citizens。The Problem of DefinitionsHarari points to the philosophical arguments between deontologists and utilitarians in order to demonstrate how difficult it is to give AI a set of instructions that would ensure it behaved as humans expect。 Deontologists argue that ethical actions follow universal moral laws， while utilitarians argue that good is defined by maximizing pleasure and minimizing pain for as many people as possible。 He notes how when deontologists face difficulties in defining their moral laws， they tend to break down and appeal to utilitarian arguments， while utilitarians tend to fall back on deontological arguments when they struggle to define relative happiness and suffering in quantitative terms。 Harari simply ends the analysis here， suggesting that if philosophers over the ages haven't been able to reconcile these two viewpoints， then it's arrogant and unwise for the designers of AI to believe that they can solve this problem。However， I believe that there is a common thread which explains why both models break down in the ways that they do， turning back on each other like an ouroboros。 In both cases the culprit is the inability of abstract concepts to fully reflect the real world without some loss of context。 Universal application of any deontological maxim will lead to disaster in some contexts， while an absolute reliance on some utilitarian calculus is ill-advised because bias is introduced both in deciding what to measure and how to calculate its value。 In short， both models are tools that are more or less useful depending on the context。 So what we've really discovered here is that some decisions which have a major impact on people's lives should never be decided purely based upon heuristics。 This poses a potential challenge and limit to the authority of legal and bureaucratic systems， but most importantly for our discussion it suggests we examine the contexts in which we allow AI algorithms to make decisions for living beings without oversight。 Rather than send diplomats to the likes of Amazon and Google， should we not question why we allow them to wield such power in the first place and define sane limits on autonomously made decisions？To his credit， towards the end of the book Harari comes to terms with this， suggesting several principles of AI governance which all involve human institutions to oversee and regulate AI。 However， he primarily discusses this on the level of algorithmic design and use in public institutions， not at the level of defining human rights and appropriate contexts for use in the first place。 Furthermore， Harari almost never stops to question the political and economic contexts in which some usages of AI are favored over others。 This leads to my final criticism of the book。Context Is EverythingThe truth is that while we can easily observe that the democratic information network is breaking down， we aren’t sure why。 This is a startling statement which reveals that in the midst of Harari's laser-focus on how information is propagated and manipulated， he has entirely set aside any consideration of the political and economic contexts in which the networks he studies exist。 While we of course cannot provide a full explanation of all the factors that have contributed to our present moment， to treat it as something beyond understanding is bizarre。Of course， a part of the answer is the way that social media fuels rage， but the more pertinent question is why does it do so in the first place？ Clearly because it's wildly profitable to do so。 In a time when the safeguards of democratic systems are being systematically eroded by an increasingly financialized economy， young people are worse off than their parents in most countries， rent is unaffordable in many cities， and global financial crises and a worsening climate crisis are ongoing with little response from traditional political leadership， it's little wonder that trust in institutions is at an all-time low and populist movements are taking advantage of the legitimate pain and anger felt by so many。 Harari of all people should understand that the absence of a coherent narrative is a dangerous thing since it leaves people in a state of confusion and pain that makes them easy targets for manipulation。 I suspect he might argue that my previous points are "just a story" and that stories， while important， cannot be fully trusted， and that it is safer and more rational to stick with what has worked best historically—the devil we know。 He is correct that caution is required， but incorrect in his refusal to recognize that the roots of many of our problems lie in the way the system functions。 He clearly espouses a form of capitalist realism that is more scientism than science—otherwise， wouldn't the scientific approach be to at least run limited tests of alternative political structures and see which performed the best？ Harari may have the luxury to maintain this form of reserved conservatism， but those harmed by our society's worst excesses certainly have no such luxury。ConclusionHarari has his blind spots， but he examines the nature of AI and its effects deeply enough to give the reader room to form their own interpretations and conclusions， regardless of the weaknesses of his own arguments。 Overall， the book is well worth reading。 For those interested in exploring the political elephant in the room， I highly recommend Technofeudalism: What Killed Capitalism by Yanis Varoufakis。 。。。more

A book following typical Yuval Noah Harari tradition。 Current events around Artificial intelligence provoke a look at the information technology from the stone age and simple information recording and storage to modern information processing and distribution。 Another thought provoking Grand History book by an author famous for his thought provoking ideas。The book will also create its fair share of controversies， but that is what a good book it all about。 Let's have these discussions now before w A book following typical Yuval Noah Harari tradition。 Current events around Artificial intelligence provoke a look at the information technology from the stone age and simple information recording and storage to modern information processing and distribution。 Another thought provoking Grand History book by an author famous for his thought provoking ideas。The book will also create its fair share of controversies， but that is what a good book it all about。 Let's have these discussions now before we make choices we regret。 。。。more

Occasionally I hear the term "Davos man。" I do not exactly know what it is， but I do not believe it is meant as a compliment， and I think it would apply to Yuval Harari， who pops up every year or so with a Big History book that is inevitably a mile wide and an inch deep。 At their worst， Harari's works can talk down to the reader。 At their best， and this is most of the time， they really shine。 They are the kind of books people like to be seen reading， like The Economist。Nexus is a work of artific Occasionally I hear the term "Davos man。" I do not exactly know what it is， but I do not believe it is meant as a compliment， and I think it would apply to Yuval Harari， who pops up every year or so with a Big History book that is inevitably a mile wide and an inch deep。 At their worst， Harari's works can talk down to the reader。 At their best， and this is most of the time， they really shine。 They are the kind of books people like to be seen reading， like The Economist。Nexus is a work of artificial-intelligence doomerism that is best appreciated by those who are interested in the subject but have little to no knowledge about it。 I don't know that the world needed 500 pages of hand-wringing in order to reach the author's bottom line， which is that societies should take steps to ensure that AI is and remains compatible with democracy。 You wonder whether he supposed anyone would disagree。Harari does not subscribe to "if it ain't broke， don't fix it。" He is a man of Big Ideas， and he is here to correct centuries of lesser minds steering you off course。 For instance， he says: "History isn't the study of the past; it is the study of change。 History teaches us what remains the same， what changes， and how things change。" I am embarrassed to admit that before reading Nexus， I believed that history studied the past。 In seriousness， though， I think that Harari's second sentence may well be true， but the first sentence need not logically follow。 And it does not take long for Harari to seem to forget his oddball redefinition and to revert to what he well knows history is: "Since [Nexus] 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。" And then: "History is often shaped not by deterministic power relations， but rather by tragic mistakes that result from believing in mesmerizing but harmful stories。"So much for "the study of change，" which did not seem to win over the ignoramuses at Merriam-Webster。 Am I being pedantic？ Knowing myself， probably， yes。 But one thing that I think is reasonable to expect from academics is the acceptance of the most basic of terms。 Not everything needs to be shaken up to wow the audiences at TED talks。 Later in the book， Harari turns his sights on the definition of democracy: "A democracy is not a system in which a majority of any size can decide to exterminate unpopular minorities; it is a system in which there are clear limits on the power of the center。" This is pretty wrong; at the founding of the American republic， democracy was the bogeyman government that was to be avoided at all costs lest a majority tyrannize the minority。 Harari likely knows this， but seeks nonetheless， for some reason that is not entirely clear， to rehabilitate democracy as an unalloyed good， and not what democracy really is。 A democracy is quite capable of exterminating unpopular minorities。Harari is open about his intention to "dedicate relatively little attention to the positive potential of algorithmic bureaucracies， because the entrepreneurs leading the AI revolution already bombard the public with enough rosy predictions about them。" It is for Harari， the Big Historian， to draw the world's attention to "the more sinister potential of algorithmic pattern recognition。"Finally， someone exposes the negative aspects of artificial intelligence。 Actually， this is being done almost constantly， which you may see for yourself by Googling "AI racist。" Now， there is nothing wrong with deciding to write a book that is critical of AI， but the fact is that AI's bulls and bears each have plenty of air time， and Harari's suggestion to the contrary does not stand to earn him much trust with his readership。 。。。more
