Programmers are obsessed with efficiency. It is the one thing I’ve encountered in essentially every coder I’ve met. Coders might be wildly diverse in other ways—politically, socially, culturally, what have you. But nearly every one found deep, almost soulful pleasure in taking something inefficient and ratcheting it up a notch. Removing the friction from a system is an aesthetic joy; their eyes blaze when they talk about making something run faster, or how they eliminated some bothersome human effort from a process.
