Homo Deus: A Brief History of TomorrowHomo Deus: A Brief History of Tomorrow by Yuval Noah Harari

My rating: [rating=3]

Blurb:

Yuval Noah Harari, author of the critically-acclaimed New York Times bestseller and international phenomenon Sapiens, returns with an equally original, compelling, and provocative book, turning his focus toward humanity’s future, and our quest to upgrade humans into gods.

Over the past century humankind has managed to do the impossible and rein in famine, plague, and war. This may seem hard to accept, but, as Harari explains in his trademark style—thorough, yet riveting—famine, plague and war have been transformed from incomprehensible and uncontrollable forces of nature into manageable challenges. For the first time ever, more people die from eating too much than from eating too little; more people die from old age than from infectious diseases; and more people commit suicide than are killed by soldiers, terrorists and criminals put together. The average American is a thousand times more likely to die from binging at McDonalds than from being blown up by Al Qaeda.

What then will replace famine, plague, and war at the top of the human agenda? As the self-made gods of planet earth, what destinies will we set ourselves, and which quests will we undertake? Homo Deus explores the projects, dreams and nightmares that will shape the twenty-first century—from overcoming death to creating artificial life. It asks the fundamental questions: Where do we go from here? And how will we protect this fragile world from our own destructive powers? This is the next stage of evolution. This is Homo Deus.

Review:

[I got a copy of this book through NetGalley.]

Interesting for the possibilities it presents, even if I’m not 100% convinced about some of the scientific explanations. On the other end, not being a specialist, I’m not discarding them either.

The writing style was very easy to follow and engaging, making it a pleasant read that I kept going back to. Some themes that could’ve been fairly dry, like recapping humanity’s history and evolution, were done so in a way that explained the essential parts without making them unpalatable.

A lot of theories in this book hinge on organisms being driven by algorithms, like machines are. Biological algorithms, that is: stimuli triggering responses that follow a set of instructions (see threat – produce adrenaline – react, that kind of instructions). Well, why not! I do enjoy my little world of believing that, because I’m a human being, I am exceptional, but if I think about it, I’m still an organic machine, with needs for fuel, and a limited self-repair ability. And so, as algorithms-based beings, there’s a fine line to thread between creating always more powerful computers, and maybe one day being driven by them, with their ability to process so much more data, and so much faster. AIs composing music or haiku, after being programmed with complex sets of algorithms to reproduce what would touch human ears and trigger emotions: something that is both fascinating (how far we’ve gone) and frightening (we’re not so unique anymore).

Following this, the book explores potential outcomes: if we end up building machines that can perform better and faster (like the Google automated car that will apply the brakes in time vs. a tired human who won’t react fast enough) , won’t we become obsolete? What can we do then, what kinds of occupations for us, and if none—can a sustainable economy grow out of this, making it sustainable for everybody, or will humans just have to go down the road of extinction?

In general, though I felt this book wasn’t going far enough in presenting those possibilities both exciting and scary (improved humans vs. free will as being only the product of our desires/algorithms). Sometimes I had the feeling I had already read something similar in a previous chapter. Somehow it seems to be better inspiration for a sci-fi novel than for actual theories about what may happen in the future?

Still, it’s food for thought. Also, from other reviews, it may be that a previous book (“Sapiens”) by this author would be more interesting, so I may be tempted to read it later.
