David Brin is recognized as one of the most iconic futurist fiction writers of our time. With huge bestsellers like "The Postman" (later turned into a movie starring Kevin Costner), David's work explores the ramifications of human choices of our collective future. In this interview, David talks about fiction's unique role in helping humanity find a beneficial future - a job done in large part by pointing out what we want to avoid most, says David. If you're an entrepreneur, researcher, or writer yourself, David's insights into "imagination" as a force for good are important to listen closely to.
