Norbert Wiener
The mathematician who founded cybernetics—the science of feedback and control in animals and machines—and who, uniquely among the architects of the computational age, issued a precise and passionate warning about what automation would do to the humans it displaced.
Norbert Wiener is the father of the loop. While John McCarthy was naming a field and Alan Turing was imagining a test, Wiener was building the mathematics that described what intelligence actually
does: not reason in the abstract, but read its environment, compare the result to its goal, and adjust. The anti-aircraft fire control system he designed during World War II—a prediction-correction loop that could track an adaptive human pilot by modeling his behavior as data—contained, in compressed form, every question the AI age would eventually confront. Wiener saw it immediately: the same mathematics that described the gun-pilot feedback dance also described the relationship between a human being and any tool sophisticated enough to respond to human behavior.
Cybernetics, the science he founded and named in his 1948 book, was the systematic elaboration of that insight. Its central claim—that purposive behavior is a property of
loops, not of isolated components—is the most consequential idea
