This is not the kind of book that I ordinarily read, but the buzz about it sounded intriguing.  It is difficult to categorize this work of nonfiction, but I guess, in a nutshell, the author goes back in history and discusses religion, art, sociology and conflicts to predict what our future possibly could be.  One of his basic premises it that most of humankind’s history has been shaped by war, plague and famine.  However, recently advances in science, medicine and agriculture have greatly diminished these disasters.  So what will shape us now?  Harari is a master of examples.  His knowledge and his ability to translate difficult concepts and ideas into simple language and situations are incredible.  Homo Deus is provocative and, at times, frightening, but I am certainly glad I read it.
