Kurzweil downplays risks because he wants to live forever
Format: Hardcover
I bought this book because I believe Kurzweil's predictions, particularly about computation acceleration, are eye-opening. However, even though The Singularity is Nearer is based on A.I. development, it devotes a lot of time to the social and biological implications of the technology, according to Kurzweil.
While I am convinced that his foresight is generally correct with regard to technological advancement, I am not persuaded that his largely rosey description of the future is correct.
Even if A.I. eventually results in certain positive outcomes, I think Kurzweil significantly underestimates the social disruption that would occur before society gets to those ideal results, if it ever does. The revolution, or its aftermath, could be so catastrophic that the disruption reaches a point of no return. In my opinion, Kurzweil underestimates possibilities like this. He seems eager to get to positive biological outcomes, particualrly in relation to nanotechnology and the aging process.
In online interviews with Kurzweil, and in this book, the thought kept coming back to me that Kurzweil's ultimate objective is to live forever. I have heard him say that he is going to extremes in attempt to live a decade or two longer so that he can benefit from advanced A.I., perhaps through digitally preserving his consciousness. These ideas reminded me of Ecclesiastes 3:11, which says that God "has put eternity into man’s heart." Even if Kurzweil's predictions about A.I., society, and even biology are correct, I don't think he will find what he is looking for. In my view, his search is ultimately about God.
A few note to lay readers: Within the first 20 pages of the book, Kurzweil inserts a sophisticated 8-page discussion on neutral networks. Don't put the book down in this section! It should have been an appendix.
Also, the last chapter is called "Dialogue with Cassandra." It's an interesting interview, but there is no preface to the conversation at the beginning of the chapter. I double-checked the introduction and the notes in the back of the book and couldn't find out more information about what I was reading or who Cassandra is. I must have missed something. Nevertheless, a quick Google search suggests that Cassandra is fictional. Perhaps this is a pop-culture reference I don't know about. Still, it's an interesting read, even if a little bizarre.

A Thought Provoking Page-turner
Format: Hardcover
To have a sense of what we can expect in the future, we have to examine the trends of the past. That is the foundation of this very readable book. Kurzweil does a thorough job of presenting historical data in graphs and tables and explaining how the trends point to what we can expect in the next quarter century. You’d think this is all technology focused, but it is much more than that. He looks at trends in violent crime (declining), health and longevity (improving), poverty (declining) and other factors and explains how social trends enhance the development of technology and in turn how technology has a positive impact on society.
This is an excellent choice for book club discussions. There’s enough detail about advancing technology to help the layperson to understand it and at the same time encourage further research. Since it a prediction of the future, one can make a argument in support of his conclusions or suggest some alternative paths. I can envision some spirited discussions.
When you think about, looking to the future is an accelerating trend in itself. The Singularity is Nearer and Kurzweil’s other books are both the catalyst and result of that trend.

AI is here and this is one of the books you should read
Format: Hardcover
If you not in tune with the changes coming to the world with the advent of AI, read this book. The front end can be a bit technical and tough to read, but the back 2/3 of the book are eye opening. A lot of change is coming over the next 5 years, most are great for the world. There will be change for all of us and those that aren’t aware and prepared could find it unsettling.
While this is a very good book, a person should be reading and listening to blogs weekly to keep up with the changes to our lives going forward. One book on the subject, while good, isn’t enough.

Good points, but too verbose and in the clouds at times.
Format: Kindle
This book has great points and analysis of trends, and a sensible outlook of what they might lead to. If you already understand the main ideas in this book, it's a good refresher and will solidify your current understanding, but may not really lead to any new "mindblowing" revelations. At times, his head is too in the clouds, and his age shows with predictions that read like bad 1960s sci-fi with things like "computorium" "gray goo" and "nanobots". While his overall points stand strong, some specific technologies he thinks will take off don't seem to have any basis or proof of concept in the real world and might be dead in the water, think "solar freakin roadways" style. He is also very full of himself, repeatedly gloating to the reader of all the "predictions" he made over the years that came true. The biggest weakness of this book is by god does he need an editor, it is way too verbose because the information is not organized well and he repeats himself A LOT. The chapters read like independent blog posts rather than a book due to how repetitive some of his points and information is. Often factoids and paragraphs are bizarrely repeated nearly verbatim pages later. But overall, it's a solid read and those uninitiated to the ideas in this book should absolutely heed their importance.
