You are not just some code monkey drone, following instructions from your boss or taking feature requests from naive end-users, _your_ choices, _your_ ethics, make a difference.

What was it that Dennis Ricthie said about his move to Bell Labs? Something like "It was 1968 and working on military projects just didn't feel right."
