I am a fan of Harari but this is a waste of money and time. I have read both his previous books. Sapiens was brilliant. Homo Deus was fascinating. This one is long winded, strained in thought and logic. I couldn't complete it. Don't bother buying.
I can't recommend this book highly enough. I often found the need to pause and consider the implications of the questions it asks. It spawned a lot of great conversations with friends and I think I'll read it again soon to help me absorb and better remember some of the excellent analysis on ideologies and philosophies.
