Fantastic book - I listened to the audio version doing my daily walks。 Great tone， language and pace - kept me totally engaged and thinking the whole time。The author was not preachy or teachy， but walked the talk from his introduction， in that he drew together lots of ideas and information and got the reader thinking about it。 Where do I stand on this？ How does this make me feel？ Do I need to find out more about this？I have a background in science， education and I am a mother and so that informe Fantastic book - I listened to the audio version doing my daily walks。 Great tone， language and pace - kept me totally engaged and thinking the whole time。The author was not preachy or teachy， but walked the talk from his introduction， in that he drew together lots of ideas and information and got the reader thinking about it。 Where do I stand on this？ How does this make me feel？ Do I need to find out more about this？I have a background in science， education and I am a mother and so that informed my approach to the education chapter - there were a couple of points the author made that caused me to shout out loud on my walk！ Good job I only had the dogs with me。He talks about the older person not being able to change/not wanting to change， how the latest generation when they hit 50 will be required to train again at a time humans would not normally want to。。。。。as a 50+ mother， I have to say my experience has been that mothers/primary caregivers who have 'paused working life' to bring up children have been doing this kind of flexible learning for many， many years - in fact （again this is anecdotal） my experience over the pandemic is that women 'over a certain age' are taking life by the horns， they are lifelong learners， crafts， arts， courses of all sorts。。。。。could we not harness this to support our children going into the future of flux？ （Rather than middle-aged white males designing education？）With that in mind， the author also said education systems are trying to catch up with the shift in learning emphasis - i。e。 skills rather than transmission of knowledge - teachers are poorly prepared for this etc。。。。。I would suggest a look， a serious look， at what Montessori Education provision is about and how it manifests in different parts of the world - I trained in both mainstream and Montessori secondary education - my children were Montessori ECE and a little primary provided - this is my opinion， but I truly believe it slots into that chapter - I think chapter 9。。。。we don't need to make up new education systems， the blueprint has been there all along。。。。。There！ You see， the author has absolutely succeeded in engaging the reader。。。top marks Mr Harari 。。。more

Lettura molto interessante questo saggio di Harari。Concentrandosi su 21 temi di attualità （le 21 lezioni del titolo）， l'autore fondamentalmente discute sullo stato delle cose nel mondo dei nostri giorni， con alcuni spunti riguardo al futuro prossimo。In particolare l'intera analisi， sotto 21 punti di vista differenti （si passa dai sistemi politici alle religioni， per dire）， è volta alla ricerca di possibili soluzioni riguardo ai tre grandi problemi del nostro 21esimo secolo: il progresso nella co Lettura molto interessante questo saggio di Harari。Concentrandosi su 21 temi di attualità （le 21 lezioni del titolo）， l'autore fondamentalmente discute sullo stato delle cose nel mondo dei nostri giorni， con alcuni spunti riguardo al futuro prossimo。In particolare l'intera analisi， sotto 21 punti di vista differenti （si passa dai sistemi politici alle religioni， per dire）， è volta alla ricerca di possibili soluzioni riguardo ai tre grandi problemi del nostro 21esimo secolo: il progresso nella conoscenza biologica， il progresso della tecnologia e， ovviamente， il famigerato cambiamento climatico。Quest'ultimo a me sembra quasi essere lasciato in secondo piano da Harari; la sua analisi si concentra in particolare sulle prime due questioni， che， in maniera un po' apocalittica， porteranno i computer/algoritmi a essere migliori degli umani sotto tutti gli aspetti。Pur essendo di fatto un saggio di tuttologia， se ne traggono delle idee e degli insegnamenti interessanti， e consiglio la lettura a tutti coloro vogliano farsi un'idea di come va il mondo oggi （non se ne esce particolarmente ottimisti， però）。 。。。more

A book that makes us think about big questions for the upcoming near and far future。 Every central idea makes one stop and think for a minute about simple facts that usually don't come up to our minds as we are always in a rush。 Great for trying to understand how the world would be and how to be prepared。 A book that makes us think about big questions for the upcoming near and far future。 Every central idea makes one stop and think for a minute about simple facts that usually don't come up to our minds as we are always in a rush。 Great for trying to understand how the world would be and how to be prepared。 。。。more

This review has been hidden because it contains spoilers。 To view it， click here。 Yuval Noah Harari me ha abierto los ojos y ha hecho que tenga una mente más abierta con este libro， le debo mucho por ello。Es increíble la cantidad de temas， problemas e información que trata en solo 346 páginas， incluyendo los que ya desarrolló en sus dos anteriores libros （Homo sapiens y Homo deus）。 Sin duda este es mi preferido de los tres。 Su estilo ameno y cercano de escritura hace que no sea nada difícil comprender desde los términos sencillos hasta los más complejos。 Realmente no necesita Yuval Noah Harari me ha abierto los ojos y ha hecho que tenga una mente más abierta con este libro， le debo mucho por ello。Es increíble la cantidad de temas， problemas e información que trata en solo 346 páginas， incluyendo los que ya desarrolló en sus dos anteriores libros （Homo sapiens y Homo deus）。 Sin duda este es mi preferido de los tres。 Su estilo ameno y cercano de escritura hace que no sea nada difícil comprender desde los términos sencillos hasta los más complejos。 Realmente no necesitas tener estudios superiores para entender el objetivo y el desarrollo del libro。 Y gracias a la extensa bibliografía puedes ampliar cualquier tema que te haya interesado， con artículos， estudios y libros。Ahora que he terminado el libro y conozco las 21 lecciones puedo verlo desde una perspectiva más global y afirmar que todas y cada una de ellas son importantes para vivir en este siglo XXI en constante cambio。 De las 21 lecciones las que más me han llegado han sido: Inmigración， Educación y Significado。Es un libro que recomiendo a cualquier persona que tenga curiosidad y ganas de aprender y de comprender el mundo en el que vivimos。 Sobre todo a los jóvenes que como yo se sienten muchas veces confundidos， perdidos pero con ganas de mejorar el mundo y la sociedad a la que pertenecemos。De todas las frases que he sacado de este libro me quedo con esta: “Para correr deprisa， no lleves contigo mucho equipaje。 Deja atrás todas tus ilusiones。 Pesan mucho。” 。。。more

I really enjoyed aspects of this book including the chapters on AI， immigration， war and topics as we move through a digital world。 Other chapters felt a little disjointed and random tangents for me。 Overall enjoyed the read

Amazing book！ Author is an innovative thinker and touches on all kinds of subjects。 Data privacy， AI， religion and immigration。 A must read。

To najlepsza w mojej ocenie książka Harariego （z tych które czytałem）。 Wyraźny skręt ku filozofii， więcej niż dotychczas wątpliwości i mniej kategorycznych stwierdzeń。 Harari zaczyna dojrzewać i ja to kupuję。 4+/5

I took up this book in 2021 and yet it remains as relevant as it was when it initially came out。 This is a very easy to comprehend read and even though the writer remains critical of probably everything that would concern a human in this century， he doesn't comes off as an arrogant skeptical writer。 I took up this book in 2021 and yet it remains as relevant as it was when it initially came out。 This is a very easy to comprehend read and even though the writer remains critical of probably everything that would concern a human in this century， he doesn't comes off as an arrogant skeptical writer。 。。。more

Many great thoughts， but a noticeable overlap with the author’s other books and between the different topics discussed。

Well some of the chapters are highly insightful， this book did justice in exploring multiple dimensions （like terrorism， ecological disruption， rise of AI etc。） in a very lucid manner！

Yet another impressive book by one of the most brilliant thinkers of our time。

Not as impressed as his other work 'Sapiens'。 I feel like it's written for older generations （and it would be a great read for them） however all the tech topics are things i've already read about years ago online which meant I didn't really learn anything new。 Not as impressed as his other work 'Sapiens'。 I feel like it's written for older generations （and it would be a great read for them） however all the tech topics are things i've already read about years ago online which meant I didn't really learn anything new。 。。。more

Sprawling and thought provoking discussion on how things might evolve over the next 100 years。 Found it hard to draw any conclusions other than we don't know how things might go but it's important to analyze things deeply， and question what reality lies beneath and what are just stories created for the purpose of persuasion。 Sprawling and thought provoking discussion on how things might evolve over the next 100 years。 Found it hard to draw any conclusions other than we don't know how things might go but it's important to analyze things deeply， and question what reality lies beneath and what are just stories created for the purpose of persuasion。 。。。more

This last book in the "Harari-trilogy" in many ways serves as a synthesis of the two previous books。 While Sapiens focused on the human past and Homo Deus on our far future， 21 Lessons focuses on the present and our more immediate future。 It does so through 21 chapters， each focusing on a certain aspect of human reality。 These are structured into five largers themes: The technological challenge， the political challenge， despair and hope， truth， and resilience。 Altough the book is interesting， ma This last book in the "Harari-trilogy" in many ways serves as a synthesis of the two previous books。 While Sapiens focused on the human past and Homo Deus on our far future， 21 Lessons focuses on the present and our more immediate future。 It does so through 21 chapters， each focusing on a certain aspect of human reality。 These are structured into five largers themes: The technological challenge， the political challenge， despair and hope， truth， and resilience。 Altough the book is interesting， many of the topics are recycled from his previous books。 One of the main insights structuring this book is that the joining of life-sciences and computer-science will radically transform our future。 Computer algorithms may controll us and a new human species may develop。 This insight is the main topic of Homo Deus。 The other main topic comes from Sapiens and relates to humanity's ability to create stories and fictions and imbue them with meaning。 These stories， which contain everything from religions to nations， ideologies and even the concept of the self， are what has allowed humanity to "conquer the world"。 These stories allowed humans to coexist in ever larger collectices and transcend genetical evolution through the much faster cultural evolution。 Based on these two recycled insights， Harari's main takeaway is that we do not truly know ourselves， as the stories we create hinder us from exploring it （if it even exists）。 Furthermore， the coming algorithmical revolution entails that soon， algorithms may know us better than we know ourselves。 Thus， his main advice is that we truly start searching for and understanding both ourselves and consciousness， before it is too late。 How？ He suggests meditation。 All in all， this is an interesting book， but it falls short of his two previous books。 Where I consider Sapiens a "masterpiece" and Homo Deus "highly interesting"， this book is merely "interesting"。 It is still definitely worth a read/listen， especially if you enjoyed the previous book， just don't expect too much from it。 。。。more

So first things first， any book claiming to have more than 2 or 3 good ideas or concepts in it should immediately raise a red flag with the reader， and this is no different。 There are not 21 lessons in here and it’s debatable that there is even one。 Rather I would call this a collection of 21 blogposts or newspaper articles on subjects that interest the author to varying degrees （spoiler: he’s really interested in AI and biotechnology）， and then heavily padded out to fill a book。 I think I would So first things first， any book claiming to have more than 2 or 3 good ideas or concepts in it should immediately raise a red flag with the reader， and this is no different。 There are not 21 lessons in here and it’s debatable that there is even one。 Rather I would call this a collection of 21 blogposts or newspaper articles on subjects that interest the author to varying degrees （spoiler: he’s really interested in AI and biotechnology）， and then heavily padded out to fill a book。 I think I would have preferred it without the padding， since over 370 pages of this was just self-indulgent as far as I am concerned。 Had it not been for a bookclub， I would have called it a day after about 150 pages。 While Sapiens had an obvious purpose， and Homo Deus was to some extent a logical follow-up， the cynic in me can see no purpose to 21 Lessons other than to take commercial advantage of the success of the first two。The author， as always， writes clearly and fluidly which allows you to turn the pages fairly quickly， and if you’re passing through an airport lounge looking for some philosophy-lite then maybe this would appeal to you。 For me， while the author is an intelligent and eloquent individual， I found the book to be a rather banal， meandering stream of consciousness of very little value。The problem wasn’t that I disagree with the author’s points， but rather that for the most part he rarely says anything that wasn’t either already obvious， or so speculative that the reader is left with no option but to say “well， yes， I suppose that could possibly happen。 Or possibly not”。 The first section of the book in particular could be summed up as “X and/or Y = maybe this”， where X and Y are more often than not AI and biotechnology。 Looking through the other reviews I see that many people enjoyed the book， so obviously there’s something in there for some。 If I was being mean I’d say it’s because Harari has discovered the trick to convincing a large number of people that he is being profound， which is basically to say things that you know most people will agree with （or at least cannot really disagree with）， but framing it in a way that they probably haven’t thought of themselves。 If I’d read some of the chapters as stand-alone newspaper articles I might have enjoyed them more， but cobbled together into a single book it just became a chore。 Some of the chapters are so banal that they have clearly been thrown in just to hit the magical number 21。 。。。more

Un saggio molto interessante， frutto di un lavoro e di una gestazione molto lunga e paziente。 L'autore comincia a mettere a ferro e fuoco diversi miti。 Uno di questi è la religione， ma non lo fa con acribia。 Il suo è un ragionamento completo， fatto senza voli pindarici。 La sola logica ci aiuta a capire， secondo lui， che la religione è una narrazione umana per tentare di spiegare l'inconoscibile。 Non nasconde qualche preoccupazione per il futuro。 Infatti con l'evoluzione sempre più massiccia dell Un saggio molto interessante， frutto di un lavoro e di una gestazione molto lunga e paziente。 L'autore comincia a mettere a ferro e fuoco diversi miti。 Uno di questi è la religione， ma non lo fa con acribia。 Il suo è un ragionamento completo， fatto senza voli pindarici。 La sola logica ci aiuta a capire， secondo lui， che la religione è una narrazione umana per tentare di spiegare l'inconoscibile。 Non nasconde qualche preoccupazione per il futuro。 Infatti con l'evoluzione sempre più massiccia dell'AI arriviamo a scoprire che il libero pensiero di un essere umano non è che una finzione。 Gli algoritmi arriveranno a comprendere meglio e più in fretta i nostri pensieri。 Come ci potremo difendere da questa onnipresenza della tecnologia？ C'è il pericolo che l'uomo non possa più decidere il suo futuro？ Non potremmo nemmeno scegliere per conto nostro un partner con cui convivere？ L'algoritmo sceglierà meglio di noi in base alle caratteristiche personali di ognuno？ Tutti interrogativi affascinanti， ai quali dare una risposta immediata è impossibile。 L'autore prova a lanciare la proposta， sta a noi analizzarla e vedere dove può essere migliorata。 。。。more

I learned a lot from this book。 I started it a while ago， then put it off for a while before getting back into it。 This book tackles a lot， so the second time around I read just a chapter or two at a time， which worked great for me。 Each chapter addresses a different concept （topics include religion， technology， immigration） and breaks it down， as a means of trying to understand how well-adapted we are to the world we live in。 The chapters of this book flow together really well。 The historical r I learned a lot from this book。 I started it a while ago， then put it off for a while before getting back into it。 This book tackles a lot， so the second time around I read just a chapter or two at a time， which worked great for me。 Each chapter addresses a different concept （topics include religion， technology， immigration） and breaks it down， as a means of trying to understand how well-adapted we are to the world we live in。 The chapters of this book flow together really well。 The historical references were a highlight for me， Yuval Noah Harari did a great job of finding interesting historical examples and connecting them to contemporary ideas about his topics。 Even where I disagreed， his points challenged me to think about my own beliefs and understand them in new ways。 One criticism I have is that it tackles many big concepts for one book， and sometimes it felt like they were oversimplified， or there wasn’t space to get to the root of some important aspects of those concepts。 My favourite takeaway from this book is when he talks about having meaningful conversations with people who have vastly different beliefs than your own。 He recommends that we take time to ask ourselves and others “what was the biggest mistake your religion， ideology， or worldview committed？ What did it get wrong？” and emphasizes the importance of understanding the fallibility of our own beliefs。 Yuval Noah Harari is a good historian and a good writer， and I learned not only some interesting facts （if we’re ever allowed to socialize again， I’ll break the ice by telling people where the term ‘hocus pocus’ came from） but also a different way of looking at some things I already knew。 。。。more

Ainda que Yuval continue trazendo pensamentos interessantes sobre a humanidade， desta vez o autor repete boa parte do que já foi dito em seus trabalhos anteriores sem acrescentar muita coisa， e foca em um discurso anti-comunista raso e gratuito。

I like the way Harari depicts singularity。 By the end of the day， it is consciousness that makes human different from AI。 Thus， mindfulness is a topic we have to raise， including in education。 One of the ways is through meditation。 It helps us connect with ourselves as a being。 In addition， I like that Harari also highlights how the world should've worked as a global entity in the present issue， global warming。 However， when it comes to fiction and about the truth， there are still points that I I like the way Harari depicts singularity。 By the end of the day， it is consciousness that makes human different from AI。 Thus， mindfulness is a topic we have to raise， including in education。 One of the ways is through meditation。 It helps us connect with ourselves as a being。 In addition， I like that Harari also highlights how the world should've worked as a global entity in the present issue， global warming。 However， when it comes to fiction and about the truth， there are still points that I disagree with him。 :） 。。。more
