I have only gotten halfway through this book and have enjoyed parts of it immensely. However, I must also concede that at times the book has felt a little sloppily edited and difficult to get through. This book is basically a collection of twenty-six interviews and conversations with well regarded scientific researchers, edited so that it reads like an essay written by the respective interviewee. What makes this book a good read are the topics discussed. For example, my favorite single essay/interview so far was by Robert Trivers, where he discusses human deception and self deception, exploring why it exists and what function it serves us.
The book is broken up into three sections, with the first section exploring questions exploring human nature, the second pondering the possible evolution of machine or human made intelligence, and the final looks into the mechanics of the workings of our universe. The authors tend to be professors of Ivy League schools, and most seem to have written full length books associated with the topics they present in this book. I think some of the topics discussed have important consequences for the future of humankind; I am looking forward to finishing this book and delving into some of the authors other full length works that I find most fascinating. If you are on the fence about this book, I would recommend you go ahead and get it. There is a good chance that you will enjoy at least parts of it enough to justify the full purchase.
