In this episode I’m continuing my series on human enhancement. I’ve previously interviewed Guilia Dominijanni on her experiments on how people adapt successfully to adding a third robotic arm. Technology continues to advance in robotics, computing, and brain-machine interfaces opening a huge pandora’s box on the potential for future enhancements. To explore this I’m going to chat with a distinguished author who has explored the issue in depth. Joel Garreau is an explorer of culture, values, and change. He has published several books, including The Nine Nations of North America. Edge City: Life on the New Frontier, and Radical Evolution: The Promise and Peril of Enhancing Our Minds, Our Bodies—and What It Means to Be Human. A long-time reporter and editor at The Washington Post, Joel is now Professor of Culture, Values and Emerging Technologies Emeritus at Arizona State University. Joel has served as a Future Tense Fellow at New America in Washington, D.C., and a fellow at Cambridge University, Oxford, the University of California at Berkeley and George Mason University and a Science Journalism Laureate at Purdue. He was a long-time member of Global Business Network, the pioneering scenario-planning organization, and is the troll of a small forest in the foothills of Virginia's Blue Ridge.
