Cybernetics is actually about feedback control systems. The original meaning has been distorted because the general public doesn't have the background to distinguish different kinds of magic. The Sperry autopilot was a cybernetic system, as were electro-mechanical gun computers.
Sure, but that hasn't been the common use for "cyber-" for the past ~46 years, which is about ~2x longer than the time between when the term "cybernetics" was coined and the "cyber" was taken from it in 1980.
