The future of humanity can go one of three ways: 1. We annihilate ourselves and go extinct 2. We continue to muddle along 3. We learn to live forever and fix everything This is a book about option three. It is based on science we have today and numbers that work. It contains a vision of how we make a future in which today's global problems get solved. You will visit a future that is possible in the next several decades. We will discuss extending your lifetime and a myriad of other subjects. Where you previously saw intractable problems, you will now see practical possibilities. I hope, after you read this book, the conversation in your head becomes one between competing positive outcomes. Most of all, I hope that the future actually becomes something like what you are about to read.
