I have to question if Jobs, Gates, or Ellison would actually be good employees in a large company like Google. It definitely takes resiliency, dedication, and tenacity to start a company; when you're joining a well established one, however, those almost seem like negative traits. I realize that Google encourages employees to try things their way (the 20% paid time they give employees to work on their own projects pretty much locks down that argument), but an organization in which every employee wants to do things their way strikes me as inefficient.
