The thing I wanted to say just before I close up, is that I did feel that there was a sort of fetishization of cybernetics from a new generation, a sort of nostalgia for something that is gone. You see, it was just a modeling tool. It was a good modeling tool, but it wasn’t a perfect modeling tool, because it was a transduction—you had to go down to go up. Cybernetics let you take a complex structure and make a simple representation.
