And for those interested in the future, I would recommend his other book "Homo Deus: A brief history of tomorrow". I must say that I enjoyed this a lot and I like how he builds his story by references various studies and summarising the key points from them. The book also felt quite "condensed", too often I get a feeling that book has material for long article, but is then artificially expanded. Homo Deus certainly did not have this problem.
