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.
