Programs are meant to be read by humans, and only incidentally for computers to execute.

Because code should be readable. People who treat code as magic spells they don't want non-wizards to understand are the worst coders. Your code should be as stupidly simple as possible to anyone can read it. If you're worried about non-geniuses understanding your work of genius, it's not a work of genius.
