In 1948 Norbert Wiener coined the term “cybernetics,” derived from the Greek term for “steersman.” The appeal of cybernetics, as Turner writes, lay in its “picture of humans and machines as dynamic, collaborating elements in a single, highly fluid, socio-technical system” where “control emerged not from the mind of a commanding officer, but from the complex, probabilistic interactions of humans, machines, and events around them.” Though the term has a slightly dated ring, its concepts remain with us. They have diffused into fields as diverse as life sciences, engineering, mathematics, business management, the arts, and anarchist theory. (As historian John Duda has pointed out, the phrase “self-organization”—now taken as a central principle within radical circles—only began to appear in translations of classic anarchist texts in the 1970s, at the height of cybernetics’ vogue.)
