40. Andy Rubin

Manager of Robotics division, Google

In March 2013, Andy Rubin stepped down from his position as the head of Google's Android mobile operating system to "start a new chapter" at the company. We didn't know what that chapter would be until December, when Google announced that he would be in charge of the company's new robotics division.

As head of this division, Rubin will lead some of Google's typical "moonshot" projects, including work with the powerful military robots the company acquired when it bought Boston Dynamics.
