The future of humanity is seen by many to be on the cusp of change. Those who predict the future see tomorrow through a lens formed from their education, experience and viewpoints. Bill Joy presages an apocalypse; Ray Kurzweil expects to ride a technologic stairway to heaven; and Jaron Lanier predicts humanity will transcend itself into an unforeseeable future. This book sees the future through the lens of a generalist. I apply critical thinking and realistic application of diverse science into my prophecy for humanity over this century. My hope is to give the general reader a rational context for viewing the changes transforming our world today. It is better to know where the tiger we are riding is headed—if we hope to hold on and maybe even steer.
