The word for where you are now, invented in a short story before the web existed, from the Greek for steersman.
Documented
Burning Chrome, then Neuromancer
William Gibson coined cyberspace in his 1982 story Burning Chrome and built it out in Neuromancer in 1984: a consensual hallucination of data. The prefix comes from cybernetics, Wiener's 1948 coinage from kybernetes, the steersman.
Assessment: Documented coinage with dated publications. The future arrived pre-named.
Stories
He predicted the internet
The legend: Gibson foresaw the net. The man himself has noted he was describing arcade kids and television, not predicting infrastructure, and he wrote it on a typewriter.
Assessment: Prophecy is easier in hindsight. The naming is documented; the crystal ball is folklore.
Interesting claims
The steersman again
The archive has been here: government and cyber share kybernan, to steer. Cyberspace means, literally, the place of steering. Who steers it is the question the word was built to dodge.
Assessment: Etymology documented by the dictionaries. The political rhyme is the archive pointing at its own shelves.
