I don't think you should be downvoted although I can see why. Your comment stems from a fundamental misconception of what Khosla means. When Khosla says that, he's specifically referring to tight iteration loops (which implies the existence and importance of plans). You believe in your hypothesis such that you're willing to try things others deem foolish, however, you're not so dogmatic that you become unable to change in the face of newly presented evidence. So while you shouldn't be so petrified or overwhelmed you dare not put a stake in the ground (strong opinions), you should simultaneously be very comfortable with changing your mind (weakly held).
