Algorithms rule our world. They are pervasive "people replacements," appearing everywhere and inside of most everything with a microprocessor. Where people used to diagnose illnesses, analyze foreign policy, make art, make war, buy media or write copy, now machine intelligence (thanks to the algorithm) does all of that. From your iPhone to your microwave to the elevator in your office, algorithms help us understand and navigate our world. They get us what we want and take us where we want to go-literally and figuratively.
