This 75-year-old NASA legend has been working in secret for 10 years building a startup that wants to outdo Intel and Google

From 1992 to 2001, Dan Goldin served as the longest-tenured Adminstrator of NASA, overseeing projects like the launch of the Space Shuttle Endeavour and the redesign of the International Space Station. After leaving NASA, Goldin spent some time bouncing around and studying robotics, before accepting a position as the president of Boston University in 2003 -- a position Goldin never officially held, because the school terminated his contract a day before he was slated to start, though he still got a 1.8 million payout. And then, Goldin mostly vanished from the public eye for over ten years. Today, the 75-year-old Goldin has reemerged to reveal what he's been working on for the last decade: KnuEdge, a top-secret startup based in San Diego, with a mission to one-up Google, AMD, and Intel with the "fundamental invention" of the next-generation computer processor. "I'm not an incrementalist; I wanted to wait for the grand slam," Goldin tells Business Insider.
