An entertaining read and good source for summer cocktail party chat, hence my two-star rating.Harari’s broad brush – or rather, paint roller – approach inevitably skips over much potentially relevant detail. This is understandable, but distorting facts to support his arguments or seemingly merely to be cute is unacceptable. It also undercuts his credibility.For example, Harari’s discussion of the dissolution of the Soviet Union includes the following.“When its members [the Soviet and Eastern European Communist elite] realized that Communism was bankrupt, they renounced force, admitted their failure, packed their suitcases and went home.”The Soviet elite hardly went home with their tails between their legs. In Russia, Boris Yeltsin was a former Politburo member and his hand-picked successor Putin came from the KGB. In Kazakhstan, the Soviet era ruler Nursultan Nazarbayev became President. Similarly, Kyrgyzstan’s first President Askar Akayev had been a deputy in the Supreme Soviet of the USSR. These are just a few of the obvious examples.This book is a good beach read but as substantive as cotton candy.
