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.”
Diamandis' background is in space exploration -- before the X Prize, he ran a company that studied low-cost launching technologies and Zero-G which offers the public the chance to train like an astronaut and experience weightlessness. But though the X Prize's first $10 million went to a space-themed challenge, Diamandis' goal now is to extend the prize into health care, social policy, education and many other fields that could use a dose of competitive innovation.
