This book, and others by this author - Sapiens and Homo Deus - have got resounding reviews. I borrowed and ‘read’ Homo Deus and 21 Lessons. Found both to be very shallow collections of everyday issues. For 21 Lessons, all that an engaged reader has to do is read the chapter headings and subtitles - and would not need to read the book. Opinions are just that; an unbiased understanding of the issue is crucial starting point. Reading the author’s view did not provide me any additional perspective on the topics. The ink and paper would have been better used elsewhere. Save your time - skip it.

If lined up on that now-ubiquitous media bias chart, this book would be left-of-center. Written in 2018 (and read/reviewed in Jan 2019) it has all of the major players in our headlines, so is, obviously, timely and apropos. As an historian, the author does well with parlaying today's goings-on into a wider-timeline perspective. Mainly the book raises interesting points, interesting perspectives and interesting conjecture/guesses. A good read.

The book is generally quite engaging and does discuss many very important issues. I found the historical, social and geopolitical commentary to be quite illuminating, but when he occasionally wanders out of his lane into more technological or scientific aspects he is much less convincing. The book also does drag a bit in the last couple chapters.

Very entertaining. Read and think...it is not required that you agree.

Take what you read here with a grain of salt. Harari is a historian, not a scientist or engineer. When his writings touch these topics, which is most of the time, it is implausible speculation, based on sensationalist guesswork by popular science journalists. Go through the chapter on Work, for example, and count how many sentences start with "What if." First, does anyone who knows what they're talking about think these what-ifs might come to pass, and second, I'm looking to you, Harari, to tell me what's going to happen, not ask me!

Worth looking into, but not as good as the previous two books, which were works of history. One might suspect it was written to capitalize on their success. Comes across as a sophomore bull session, or what we used to call mental masturbation, meaning that it feels good to think about, but it just doesn't get the job done, if you know what I mean, and I think you do.

I was going to rate this book at 3 stars. However agonizing through the last two chapters which for me were just a numbing of a delusional mind, I downgraded it to 2 stars.

Twelve hours of my life well spent. There are enough concepts in this book to keep you pondering for the rest of your life. Best read with a very open mind.

I read the reviews of 21 lessons for 21 century, mixed. That readers-views demonstrate how complex is the issue(s). AI alone is said to solve problems is a myth; recent neuroscience studies shed light on the complexity of the neural works and the ever-changing matrix of that. To surrender to AI is give up our soul, the energy of the soul is so vastly superior that is immeasurable! Figuring out math solution faster than the fastest computer is one such, sterilization of solid gold ellipsoid within a human mouth is another science breaker. These and many others challenge AI on its face and will continue to demonstrate the ultimate power of the soul-energy. Any book is exciting to show modern thinking and commercial trends, cannot predict, pin-pointed.
thanks for reading

Excellent book. Read it. Lose your illusions. Well at least some of them.

I enjoyed the topics Harari brought up giving valuable perspectives for the readers to think things over critically. Some of the topics poses existential questions that humanity of all levels should pay attention to and act accordingly. It is not someone else's problem or future generations' problem. It is our problem, and it requires our action, especially responsible actions instead of kicking the proverbial can down the road.
