Where Harari writes about the future and the technology that is coming the book is actually interesting and thought provoking, but about 2/3 is devoted to him narrating history through his own biases. Such as throughout the book he condemns religion for all sorts of reasons, and yet claims our feelings are algorithms for understanding the world, as if religious teachings don't distill thousands of years of contemplation and wisdom about human feelings and cultural understanding.
All in all if your a Secular Liberal Humanist, whom sympathizes with Marx and Lenin, this book will speak right to you and reinforce your beliefs and cement your biases even further, as this book may as well be propaganda.
I felt that the author used his knowledge of history and the modern world to paint an enigmatic portrait of the future. I was impressed and captivated throughout. The amount of research and study it took to put his works together is a representation of the questions and ideas that he presents. His seemingly dark yet profound outlook on free will made me question my own foundational beliefs of cognition, while simultaneously, his relentless use of scientific facts and sound theories gave little room to argue. It is somewhat disheartening to entertain the idea that the world as we know it may be spiraling out of control, but comforting at the same time that the spiraling effect may answer the unanswerable questions that we humans have always had and never been able to answer. As far as the evolution of technology goes, I am an idealist of the Jacque Fresco school of thought. There is no reason to believe that we can't mutually coexist with technology and benefit from it no matter how advanced it becomes, barring the wrong people aren't influential enough to lead it down a path of avarice and clandestine ends. However, Harari's outlined suppositions possess an almost magnetic captivation, due to his matter of fact approach. His logic and reasoning are grounded with mostly objective knowledge. Unless you are primarily a subjective, spiritual, or religious person, it would be hard to argue his positions. And even then, you would be overwhelmed by the vast amount of knowledge. Being that he knows more about the various religions of the world than most people know about their own religion.
If you are a religious person that is scared to death to have your foundation shaken, this book isn't for you. Wether you take that as a challenge or a warning is up to you. At the very least this book will make a religious person very upset.
This entire book gave the impression of an attempt to present mundane rhetorical tricks as profound insights. The majority of the book was colored by a recasting of the definition of 'religion' in a way that added or elucidated nothing but was instead used for dramatic effect. This book felt like it was presenting material that had been cut from Harari's Sapiens (a better book indeed). I am tempted to believe that Harari was surprised by the success of Sapiens and simply wrote Homo Deus as a cash grab. I wish that I had not paid him for the scheme.
One of the best book I have ever read. And I have read a lot of books. It is so deep and reasonable that it is scary. Author has amazing ability to analyse us, world.
Opens up our horizont by millions miles.
As other reviewers have noted, the third part of this book is the most impressive. The first 40% of the book felt like a "... last time, in sapiens ..." rehashing, but it's welcomed and genuinely different from sapiens. The latter half of the book is new, engaging and absolutely brilliant. Harari is an entertaining writer and his synthesis of information is concise and easy to follow. I imagine 10 years from now this book will appear as click bait (or whatever equivalent we then have) saying "This is the book that predicted it all."
I really liked Harari's previous work, Sapiens. A lot. But, holy crap, where did this come from??!
This book is so expansive, so entertaining, so prescient, and so crammed with refreshing wisdom that I don't even know where to begin!
I'll start by saying this is one of the top three modern philosophical EPICS of our time. It paints a future that is not only believable, but -for the most part - unavoidable. Its common sense anecdotes are insightful, which seems like an oxymoron at first, but makes sense when you really think about it. Like Jerry Seinfeld, Harari has a way of making you see reality through a lens that you never knew existed before; or maybe you knew it existed, but were always too afraid to hold it up to your iris.
Everyone should read this book. I don't say that lightly, either. EVERYONE. It will make you see reality differently. And, at the end of the day, any book that can do that is WELL WORTH your time!
