Sapiens presented some good ideas. Unfortunately, the stream of ideas are often flawed with facts that are untrue. That really gets me. Don’t state a lie to sell a book. There were lots of ideas that could have been elaborated on. IE. the mechanism for the spread is glossed over and the story continues with the details after Sapiens has spread across Europe and Asian. Overall read the summary, and you’ll have some good ideas without the flawed writing.
