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.
