Cybernetics comes from the Greek word meaning to steer or to pilot. In the video he also mention that it’s a spiral, you advance, you go forward. Which mean that someone will do something, analyze it, then steer yourself to the goal you want achieve. And this feedback is what cybernetics is. “Setting goals and questioning those goals is something that cybernetics lets someone do consciously and explicitly”.
