Book note: "Homo Deus" by Yuval Noah Harari

I am apparently one of the few that has not read Yuval Noah Harari's first book "Sapiens". I did not even realize this until I got his new book "Homo Deus: a brief history of tomorrow". Now after I have read "Homo Deus" I understand why the first book got so much attention and praise. It is not often you find a book that takes on the biggest possible perspective of humanity, its history and future, and manages to do it without completely making a mess of it.

After I read the book, I read several reviews of it, most of them were quite bad. They do not really seem to get the basic ideas in the book and therefore end up with arguments and critique that clearly David Runciman in the Guardian. Runciman presents the book in a way that, in my view, represents the ideas quite well. I will therefore not here write much about the book, instead, just read his review.

A couple of my own thoughts about the book. Harari introduces the notion of "Dataism" at the end of the book. I found the chapter "The Data Religion" to be fascinating. The way he describes dataism, what it means and what it leads to, opens up many questions and challenges especially related to my own field. Of course, Harari is extraordinary bold, uses the biggest possible brush to paint his picture, which means that as a reader you easily react on details that you may find incorrect or problematic. That is unfortunate since it means you might miss the bigger picture. To get something from a book like this, you have to engage with it at the level of the big ideas it tries to explore. Anyway, the notion that dataism is the next religion and that it can make humanism extinct is quite an ambitious and maybe to many a scary idea. Harari states that if this is correct then humans are not 'needed' anymore.

One strength of the book is, of course, the way it is written. It is easy and fun to read. Great examples and clear arguments. The text is full of conclusions and statements that most would not even dare to express. I truly enjoyed reading the book and I agree with Daniel Kahneman who write on the back of the book "Homo Deus will shock you. It will entertain you. Above all, it will make you think in ways you had not thought before".
