If you’re looking for some optimism for the future, look no further than Peter Diamandis. He runs the X Prize Foundation, which offers large cash incentive prizes to inventors who can solve grand challenges like space flight, low-cost mobile medical diagnostics and oil spill cleanup. He is the chair of Singularity University, which teaches executives and grad students about exponentially growing technologies.

Onstage at TED2012, Peter Diamandis makes a case for optimism — that we’ll invent, innovate and create ways to solve the challenges that loom over us. “I’m not saying we don’t have our set of problems; we surely do. But ultimately, we knock them down.”.
