I watched this video last night from TED Talks. Regina Dugan, who was a director at DARPA (now at Google), does an outstanding job chronicling the experience of her group as well as bringing in some larger context on failure and the role that it plays in innovation. It reminds me of the quote from Einstein; “If we knew what we were doing it wouldn’t be called research”. Many discoveries are serendipitous and being able to pursue an endeavor without fearing failure can allow one to fail early rather than committing a larger amount of resources (both time and money) to a project as it continues.
