Cyber what?

"Cyberspace", "cybersex", "cyberworld" and even "cybernet". What do these terms mean?

From the Oxford Dictionary Online:

cyber-

/sibr/

  • combining form relating to information technology, the Internet, and virtual reality: cyberspace.

  — ORIGIN from CYBERNETICS.

Apparently the root is Greek: kubernetes, which is a person that steered a ship or vessel. So, basically something that controls or directs a machine. In today's parlance that might be a computer. Cybernetics deals with control systems - particularly that relating to the interaction, on a symbiotic level, of organism and machine. A cyborg is just that - a machine (in the mechanical sense) in control of an organism.

These days though, the cyber- prefix is applied to the Internet: a machine in control of an organism? Cybersex... machine sex? That's not the case though. The Internet is basically the tool by which humans control communication. It's not a vessel or ship, it's not steered and it doesn't have any moving parts.

When I began using the Internet, back in the early 1990s, smilies were used to denote sarcasm, virtual is how we described the 'world' or 'space', and netsex was the term used to describe text-based sexual interaction of humans through the medium of computer screens using keyboards. No mechanical parts are used... well... maybe some are, but that falls outside the scope of this article! Certainly, netsex is not the sexual interaction of cyborgs that the word cybersex implies. Internet space, or the virtual world, is not the inner-workings of a cyborg, or the physical dimensions of it.

I'm curious as to when the Oxford English Dictionary decided to add this word, incorrectly in my opinion, to it's lexicon, and why. Why does the dictionary not describe the meaning of the word in relation to human-machine hybrids or androids etcetera.
