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.
