      Briefly, then decided it was mostly Wiener’s delusions of grandeur picked up by people who he could easily bullshit, adding very little to the basic engineering subject. Did have a paper in IEEE systems, cybernetics, and man journal though :)

      Control theory is bread-and-butter engineering routinely used in everything from thermostats to autopilots to missile guidance. Dates to 1930s. Wiener made a few key early contributions in the 1940s and then forked off into a cult of personality pseudoscience ama cybernetics.

      Yeah he’s one of the principals. It was really never more than a track of famous conferences and a few political enthusiasts. To get a sense of control theory browse the ToC of this standard undergrad text.https://www.amazon.com/Modern-Control-Engineering-Katsuhiko-Ogata/dp/0136156738 …

      That’s a good example to see the differences. In control theory the statement is called the internal model principle and is used in actual design. Like to design a system that rejects a sinusoid disturbance you’d put an oscillator in. The cybernetics version is more a zen koan.
