How much messiness should we accept? What balance of the new and familiar is the most fulfilling? These may seem like uniquely human quandaries, but they are not. Computers, like us, confront limited space and time, so computer scientists have been grappling with similar problems for decades. And the solutions they\u2019ve found have much to teach us.<\/p>\n In a dazzlingly interdisciplinary work, Brian Christian<\/a> and Tom Griffiths<\/a> show how algorithms developed for computers also untangle very human questions. They explain how to have better hunches and when to leave things to chance, how to deal with overwhelming choices and how best to connect with others.
