Recently, I've been looking into the life of the brilliant Norbert Wiener and the field he spawned, cybernetics. Before reading into it, I thought "cybernetics" was a pseudo-science-new-wave-steam-punk-post-human-cyborg-thing, so I was surprised to discover it's really just a generalization of control theory from industrial engineering to both animal and digital systems.

Wanting to find out more about the subject, I started looking for resources but found almost nothing dated in the last 20 years.

What's happened to this field? Was it simply too broad and the community fragmented and specialized? Did it die with the original creators–– there are no people left with the wide breadth of interdisciplinary knowledge left to maintain it? Or did the term just suffer a semantic creep that led researchers away?

Appreciate any insights.

    $\begingroup$ Elon Musk's company Neuralink - An integrated brain-machine interface platform with thousands of channels is currently active in this area. The Nature article - Return of Cybernetics outlines the return of inter-disciplinary interest into neural interfaces. $\endgroup$

    $\begingroup$ Wikipedia treats "cybernetics" as a very expansive umbrella term which may have reflected the original ambitions of the founders, but did not make it as a unified field with such scope. What happened to the viable parts of it is that they specialized into modern computer science/AI and information theory, while the control aspects mostly remained under their original headings in mathematics and engineering. Cybernetics as a distinctive field is now mostly obsolete, but some legacy journals remain, e.g. Cybernetics and Systems. $\endgroup$

    $\begingroup$ The term "Cybernetics" is rarely used nowadays; it just dissolved in the neighboring areas of science (like control theory, signal processing etc.) But it was never called a pseudo-science by anyone who understands what it is, except in Soviet Union. $\endgroup$ Jul 23 '20 at 23:48

    $\begingroup$ Maybe useful DA Novikov, Cybernetics: From Past to Future (Springer, 2016) $\endgroup$ Jul 24 '20 at 10:40

Perhaps Cybernetics lost some of its charm because Claude Shannon created Communications Theory 1 in 1948, which put the hazy concept of "communications" in firm, mathematical terms, which caused it to suddenly be a well-defined discipline. Since Communications was half of Cybernetics, the latter must have suffered as a result.

Although not directly related to your question, it is interesting to note that "General Semantics" 2 by Alfred Korzybski seems to have followed a similar loss of popularity.
