"The meaning of the term "cybernetics" is today somewhat different from that used when Wiener, McCulloch, Rosenblueth, Bigelow and others used the Greek word "Kybernetes," or helmsmen, to describe an automatic computer... the definition, which I first gave in 1966: "Cybernetics describes an intelligent activity or event which can be expressed in algorithms. Algorithms, in turn, refer to a system of instructions which describes unambiguously and accurately an interaction which is equivalent to a given type of flux of intelligence and a subsequent, controlled activity. The development of cybernetics aims, among other things, at the design and reproduction of functions which are peculiar to intelligent organism.""
