"Wiener's dream of a universal science of communication and control has faded with the years. Cybernetics has given rise to new areas like cognitive science and stimulated valuable research in numerous other fields. But almost no one today calls themselves a cyberneticist. Some believe that Wiener's project fell victim to scientific fashion, its funding sucked away by flashy but ultimately pointless AI research. Others think cybernetics was killed by the basic problem that the nuts-and-bolts mechanisms of control and communication in machines are significantly different from those in animals, and neither are very like control and communication in society. So cybernetics, which was based on an inspired generalization, fell victim to its inability to deal with details. Whichever perspective is true (and as with most such stories, the truth is likely to be a mixture of both), cybernetics has left two important cultural residues behind. The first is its picture of the world as a collection of networks. The second is its intuition that there's not as much clear blue water between people and machines as some would like to believe. These still-controversial concepts are at the bionic heart of the cyborg, which is alive and well, and constructing itself in a laboratory near you."
