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.

Audiobook has TERRIBLE narrator; book is very techical
Format: Hardcover
So this is a fascinating book -- the author has an incredible depth and breadth of knowledge in a vast array of technical (and medical) subjects. Note this is a much more technical book than your typical science book intended for the educated layperson. That's a big plus for me, but others might be put off by the level of detail. The main fault with the book is the audiobook's narrator, Adam Barr. He has a deep voice that is easy to understand, but he is just about as dull as can be, sounding as if he's reading the ingredients on a can of soup. I ended up buying the hardcover version of the book because the audiobook could not hold my attention -- because of the narrator, not because of the content, which is amazing. I wish more narrators would take a page (ha ha) from talented pros such as Ray Porter and Wil Wheaton. Just because this book is nonfiction doesn't mean it can't be read with heart, as if the reader was speaking to me personally, with enthusiasm, and not just reading words out loud.

The Final Warning
Format: Kindle
No more heads up after this one guys. Ray is not known for missing futurological insights. He’s placed many predictions within this work and it’s my belief that they will occur even sooner than he imagines. That said, the time for comfort with our current way of living is over, and this book functions as the last glance of insight to carry you through with knowledge of what could be. Without it, you are very likely to be entirely blindsighted. The world is changing much faster than the vast majority of people realize. Even those paying close attention to technology. Learn what you can do you can prepare. This book is likely the best way to get ahead of the curve, and adds many new concepts and refinement than the first in the series
