coined 1948 by U.S. mathematician Norbert Wiener (1894-1964) from Gk. kybernetes "steersman," perhaps based on 1830s Fr. cybernétique "the art of governing."
"The future offers very little hope for those who expect that our new mechanical slaves will offer us a world in which we may rest from thinking. Help us they may, but at the cost of supreme demands upon our honesty and our intelligence." [Norbert Weiner, "God and Golem, Inc.," 1964]

c.1300, from O.Fr. governer "govern," from L. gubernare "to direct, rule, guide," originally "to steer," from Gk. kybernan "to steer or pilot a ship, direct" (the root of cybernetics). The -k- to -g- sound shift is perhaps via the medium of Etruscan.
cyber Look up cyber at Dictionary.com
as a prefix, ultimately from cybernetics (q.v.). It enjoyed explosive use with the rise of the Internet early 1990s. One researcher (Nagel) counted 104 words formed from it by 1994. Cyberpunk (by 1986) and cyberspace were among the earliest.
Cyber is such a perfect prefix. Because nobody has any idea what it means, it can be grafted onto any old word to make it seem new, cool -- and therefore strange, spooky. ["New York" magazine, Dec. 23, 1996]
As a stand-alone, it is attested by 1998 as short for cybersex (which is attested by 1995).
