Being humble or that " I don't know " attitude does not guarantee that one should be any better programmer. But at least being humble would leverage more possible potential to learn more or dig in to the subject more.Concentrating at the intricacies of the computing applications across many distant, wide and futuristic verticals , by one person , would rather be an exhaustive and daunting task, so its difficult to say who the best programmer is.Nevertheless , there have been quite a few people who have changed the face of our life altogether,by developing great applications and practical ideas - should be the good contenders to this list, but who outweighs the rest and emerge to be the winner- let them battle out themselves.
