Delightfully terrifying!

ByAlways Trust In Bookson October 30, 2016

Audience: Readers looking ahead to the future and wondering what the world may look like in 100 years. People interested in all aspects of humanity and the science, psychology, technology and politics behind everything we have done, are doing and will do in the future.

Summed up in a few words: Relevant. Unbiased. Necessary.

First Impression: Homo Deus was a book I was really excited to read! The tagline ' A brief history of tomorrow' really intrigued me as I don't really put much thought into my life life years down the line. This book is a must read! Not only does Harari talk about the future, he does so in such a wide spectrum of elements and details that I was impressed by how much information I took in. It also helps that he kept the language to an accessible and easy to read level, though there is technicality in some of the areas of the text. When I finished the book I was stuck between two very distinct and conflicting thoughts, the first was that I am comfortable with the steps that we as humans are taking to secure our futures and the other is that I am massively concerned about our future.

Book Summary/Review

Homo Deus: A Brief History Of Tomorrow is one of many groundbreaking books that are coming out this year that will influence certain non-fiction titles for the next decade or so. I have many of these books on my to-read list but I started with Homo Deus as it seem like a book that would cover all the bases and show me what we as humans are doing to secure our futures on earth and how we plan to do so. Yuval Noah Harari definitely achieves this, though it took a long time to get to sections I really wanted to read.

Homo Deus started off strong, outlining what we have achieved up until today and where we may take life in the future. It did this from many different perspectives from agriculture, technology, economy, geography and medicine to psychology, politics, sociology, existentialism and science and it was incredibly interesting.

Unfortunately for some who already have read a lot of books about human history, Harari does typical 'to see where we are going we must go back to the start' section which for me was slightly irritating but if you know very little about our past, our struggles and how we came to be then you will be very pleased with this section. I know that sounds like a complaint but it is really just a warning, because though it has been covered many times before, I felt that Harari did a great job with this section.

The next section of the book covers how we brought the world to be in the last 2 or 3 centuries and again it has been done before, but Harari has such depth, understanding and control of the subject that I was left thoroughly informed and prepared for the last section, the one I had been waiting for, where are we going!

I was massively impressed with this section, it both made me excited about the future, what technologies, scientific discoveries and biological/medicinal advances we may create or discover. It also scared the hell out of me too, where societies may change, how our life may become automated and where religion may evolve.

I am not sure whether I enjoyed the subject or the author the most when reading this book. I feel that it is the subject overall as it is uncharted territory for me so to speak, I know I read a lot of science fiction but I have never read a book where someone has sat down and outlined all aspects of our actual humanity and extrapolated them into a realistic vision of our future, please let me know if you have read anything like this before.

In terms of content, it is overwhelming, Harari must do nothing but research as he knows more about humanity than I will ever know, but he is so down to earth and treats readers fairly, not bogging everything down in technicality and jargon but bringing the subject down to a comprehensible and comfortable level. This meant I could read this book without having to look up every other word and pretend I understanding what he is saying instead of actually understanding what he is saying.

If you want to know what we went through to get to this point, the famine, the war, the disease and hunger. If you want to know what life truly looks like today with social media, algorithms, happiness, religion and art. And if you want a vivid depiction of what are future may or may not become then Homo Deus is the book you want. I was most impressed with how Harari was so unbiased, he treated each viewpoint and opinion with respect and lets the reader make their own mind up of what to make of each scenario. Also there are great stories and case studies to back up his points as well as images to give the insights some context or texture.

Fortunately this is not an 'all is lost' viewpoint on the future of human existence but it is definitely not all peachy and full of promise. Read the book, see what you think and tell me what you thought on Harari's approach to this topic. I found Homo Deus engaging, thought provoking, extremely concerning and delightfully promising as well.

A mix of deft writing, sweeping ideas and incomplete speculation: 3.5 stars

ByAshutosh S. Jogalekaron January 5, 2017

Yuval Noah Harari's "Homo Deus" continues the tradition introduced in his previous book "Sapiens": clever, clear and humorous writing, intelligent analogies and a remarkable sweep through human history, culture, intellect and technology. In general it is as readable as "Sapiens" but suffers from a few limitations.

On the positive side, Mr. Harari brings the same colorful and thought-provoking writing and broad grasp of humanity, both ancient and contemporary, to the table. He starts with exploring the three main causes of human misery through the ages - disease, starvation and war - and talks extensively about how improved technological development, liberal political and cultural institutions and economic freedom have led to very significant declines in each of these maladies. Continuing his theme from "Sapiens", a major part of the discussion is devoted to shared zeitgeists like religion and other forms of belief that, notwithstanding some of their pernicious effects, can unify a remarkably large number of people across the world in striving together for humanity's betterment. As in "Sapiens", Mr. Harari enlivens his discussion with popular analogies from current culture ranging from McDonald's and modern marriage to American politics and pop music. Mr. Harari's basic take is that science and technology combined with a shared sense of morality have created a solid liberal framework around the world that puts individual rights front and center. There are undoubtedly communities that don't respect individual rights as much as others, but these are usually seen as challenging the centuries-long march toward liberal individualism rather than upholding the global trend.

The discussion above covers about two thirds of the book. About half of this material is recycled from "Sapiens" with a few fresh perspectives and analogies. The most important general message that Mr. Harari delivers, especially in the last one third of the book, is that this long and inevitable-sounding imperative of liberal freedom is now ironically threatened by the very forces that enabled it, most notably the forces of technology and globalization. Foremost among these are artificial intelligence (AI) and machine learning. These significant new developments are gradually making human beings cede their authority to machines, in ways small and big, explicitly and quietly. Ranging from dating to medical diagnosis, from the care of the elderly to household work, entire industries now stand to both benefit and be complemented or even superseded by the march of the machines. Mr. Harari speculates about a bold vision in which most manual labor has been taken over by machines and true human input is limited only to a very limited number of people, many of whom because of their creativity and demand will likely be in the top financial echelons of society. How will the rich and the poor live in these societies? We have already seen how the technological decimation of parts of the working class was a major theme in the 2016 election in the United States and the vote for Brexit in the United Kingdom. It was also a factor that was woefully ignored in the public discussion leading up to these events, probably because it is much easier to provoke human beings against other human beings rather than against cold, impersonal machines. And yet it is the cold, impersonal machines which will increasingly interfere with human lives. How will social harmony be preserved in the face of such interference? If people whose jobs are now being done by machines get bored, what new forms of entertainment and work will we have to invent to keep them occupied? Man after all is a thinking creature, and extended boredom can cause all sorts of psychological and social problems. If the division of labor between machines and men becomes extreme, will society fragment into H. G. Wells's vision of two species, one of which literally feeds on the other even as it sustains it?

These are all tantalizing as well as concerning questions, but while Mr. Harari does hold forth on them with some intensity and imagination, this part of the book is where his limitations become clear. Since the argument about ceding human authority to machines is also a central one, the omission also unfortunately appears to me to be a serious one. The problem is that Mr. Harari is an anthropologist and social scientist, not an engineer, computer scientist or biologist, and many of the questions of AI are firmly grounded in engineering and software algorithms. There are mountains of literature written about machine learning and AI and especially their technical strengths and limitations, but Mr. Harari makes few efforts to follow them or to explicate their central arguments. Unfortunately there is a lot of hype these days about AI, and Mr. Harari dwells on some of the fanciful hype without grounding us in reality. In short, his take on AI is slim on details, and he makes sweeping and often one-sided arguments while largely skirting clear of the raw facts. The same goes for his treatment for biology. He mentions gene editing several times, and there is no doubt that this technology is going to make some significant inroads into our lives, but what is missing is a realistic discussion of what biotechnology can or cannot do. It is one thing to mention brain-machine interfaces that would allow our brains to access supercomputer-like speeds in an offhand manner; it's another to actually discuss to what extent this would be feasible and what the best science of our day has to say about it.

In the field of AI, particularly missing is a discussion of neural networks and deep learning which are two of the main tools used in AI research. Also missing is a view of a plurality of AI scenarios in which machines either complement, subjugate or are largely tamed by humans. When it comes to AI and the future, while general trends are going to be important, much of the devil will be in the details - details which decide how the actual applications of AI will be sliced and diced. This is an arena in which even Mr. Harari's capacious intellect falls short. The ensuing discussion thus seems tantalizing but does not give us a clear idea of the actual potential of machine technology to impact human culture and civilization. For reading more about these aspects, I would recommend books like Nick Bostrom's "Superintelligence", Pedro Domingos's "The Master Algorithm" and John Markoff's "Machines of Loving Grace". All these books delve into the actual details that sum up the promise and fear of artificial intelligence.

Notwithstanding these limitations, the book is certainly readable, especially if you haven't read "Sapiens" before. Mr. Harari's writing is often crisp, the play of his words is deftly clever and the reach of his mind and imagination immerses us in a grand landscape of ideas and history. At the very least he gives us a very good idea of how far we as human beings have come and how far we still have to go. As a proficient prognosticator Mr. Harari's crystal ball remains murky, but as a surveyor of past human accomplishments his robust and unique abilities are still impressive and worth admiring.

Heartening, uplifting wisdom

ByEdward A. Tomchinon April 20, 2017

Format: PaperbackVerified Purchase

The book arrived very fast in excllent new condition. So far I'm only 100 or so pages into it but I'm impressed with it. Harari's going down paths I thought I traveled alone, but in much better detail and description. If you think well of our species this is a heartening book to read.

Start to think about the future but don't expect a description of how it will be

ByAmazon Customeron July 11, 2017

Format: Kindle EditionVerified Purchase

I have to confess that I haven't read the previous book ("Sapiens: a brief history of humankind") of this author, so the first chapters did not look repetitive to me although they might be for someone who has read Sapiens. If you are looking for a book that tells you how the future will look like, this is not your book. If you are looking for a book that gives you the tools to think about how the future MIGHT look like, then you will love this book as much as I do. The book helps you to adopt a different point of view when thinking about humankind and the power of the new "ideology" based on algorithms and data that has developed in the XXIst century and leave you with a blank slate to imagine how our society will evolve (or disappear.)

Getting Ready For Near Futute

ByKindle Customeron March 23, 2017

Format: Kindle EditionVerified Purchase

Yuval Noah summarized the accumulated scientific knowledge that most people are yet blind to and tried to warn them, urge them to prepare for the inevitable progress that will hit them sooner than they can imagine. Yuval has obviously kept himself up to date with the latest scientific progress and digested the information well. His projections are quite accurate and realistic. He has reviewed the latest developments genetics, behavioral sciences, cybernetics and so on and translated their findings into everyday peoples language. Hope people learn a lot from this book and update themselves accordingly.

If you have not read Harari's previous book you can jump straight to this one - it contains a pretty good summary of his ideas and notions expressed in his first book.
Harari's take on a lot of modern issues is surprising but well research and thought out. thus I founding it hard to argue with logic and ideas.

Mandatory reading for ALL Homo Sapiens!

ByLance Peytonon July 1, 2017

Format: PaperbackVerified Purchase

WOW!!! A Real eye opener. As an amateur student of evolution, the human race and it's future and most sci-fi themes, I find Mr. Harari's expositions and conclusions to be at least highly believable if not downright accurate! There's plenty of meat for a new generation of sci-fi plots, historical angles and unforeseen self-extinction twists! Oh, yeah! It's also a really easy read!

Thought provoking and prophetic

ByAmazon Useron April 30, 2017

Format: Kindle EditionVerified Purchase

Yuval does it again with Homo Deus. He treats a very difficult subject of what is coming tomorrow, where he scans a very broad front of developments and condenses the information in a way only Yuval can. Thought provoking, prodding and some times (most of the times) humorous author leads on the path to future showing the treatment we meted out to our lesser intelligent mammal cousins and sometimes wonders whether the new AI or IOT will do the same for us. Sit back and think deeply about this. This is the story of what might happen to your children.

Another Provocative Tract from Yuval Noah Harari

ByWilliam Davison March 26, 2017

Format: HardcoverVerified Purchase

Although I preferred his prior book "Sapiens" I found "Homo Deus" to be equally, if not more provocative. The possible futures he describes for Homo Sapiens is pretty grim, at least from my liberal, humanist perspective. His tone sometimes borders on arrogant, but it's always lively.

ByAmazon Customeron June 20, 2017

Format: HardcoverVerified Purchase

This is probably my first review on Amazon. The world is changing in such a humanly incomprehensible speed that humans are becoming obsolete by the second. This book reads both as history, prophecy, and warning.
Having bought the audiobook first was a good decision for me because I heard it as a student would have heard a professor. It is dense material and it is not relaxed reading by any means. I later bought the print version since I wanted to highlight some passages. The book raises more questions than it answers, but the questions are the essential ones we should ask regarding the survival of the human race.

Interesting predictions about the future of humankind.

ByPeter D. Blomquiston May 26, 2017

Format: PaperbackVerified Purchase

A lot of good information especially towards the end of the book where the author speculates about the future of humans, what kind of jobs there will be in the future, and about human's relationship with Artificial Intelligence. If we survive climate change, population increase and atomic bombs, the next hundred years will see significant, mind-boggling change. Author is a very good writer. Easy to read.

interesting premise but did not follow through

ByAlexandra Y. Kwanon June 27, 2017

Format: Kindle EditionVerified Purchase

It seems the author forgot his original premise about how our species will become like gods and ended up focusing on how humans will be reduced to algorithms in the future instead. I also disagree with his definition of what constitutes a religion.
The prose reads fine, though I don't find it as convincing as Sapiens.
