I've noticed it before but never thought too deeply about it. Where did this 'stereotypical hacker' image stem from anyway? Computer 'nerds' are often cast with pressed button-up shirts, pocket protectors, and thick glasses. But if they are a 'bad nerd', they suddenly don a mysterious hoodie that covers their face as they work in a cave-like room like some kind of new-age techno-troglodyte?
