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.
