In the last thousand years, we've been transported from knights on horses to kids on computers. Life and how we live has been incredibly transformed, but humanity has paid a high price for its incredible growth. Today's top experts look back at the last millennium and the thinking processes that simultaneously built civilization and spread devastation to look for lessons to guide us through the next thousand years. Joining host Robert Lawrence Kuhn are creativity pioneer Edward de Bono; artificial intelligence expert Edward Feigenbaum; futurist Graham T.T. Molitor; planetary scientist Bruce Murray; and best-selling author and surgeon Sherwin Nuland.
