The Zen of Jeff Bezos: "Bezos took what he calls 'the bold, stupid path' and stocked his shelves with a million titles."
I am a big fan of stupidity. Much as Larry Wall believes the virtues of a programmer to be laziness, hubris, and impatience, I think stupidity is massively under-rated. As a culture we don't like admitting that we can't foresee the consequences of everything we do; and as such we're driven to do smart stuff and ignore those consequences.
