Using "cyber" as a noun there seems language coded for government. DC has a love of "the cyber" but do technologists use the term that way when not pointing at government?
My theory is this: Until recently, "cyber x" meant the same as "Internet x" (because Internet ≈ Cyberspace), except that "cyber" sounds a bit cooler, and security organizations wanted to sound especially cool, so they were the ones who used "cyber" most, causing the shift in meaning.
Cybernetics is actually about feedback control systems. The original meaning has been distorted because the general public doesn't have the background to distinguish different kinds of magic. The Sperry autopilot was a cybernetic system, as were electro-mechanical gun computers.
Sure, but that hasn't been the common use for "cyber-" for the past ~46 years, which is about ~2x longer than the time between when the term "cybernetics" was coined and the "cyber" was taken from it in 1980.
When I was like 12, I remember my fellow horny youths (or it could have been anyone, I guess!) in AOL chatrooms constantly asking each other "wanna ciber?"
That would be "cyber" as a verb, not "cyber" as a noun. Would anyone have understood what you meant back then if you'd said "I was in a cyber just now" instead of "I was cybering just now"?
