'Cyber-' comes from Greek 'kybernetes' (steersman) — the same root that gave us 'govern.'
Relating to or characteristic of the culture of computers, information technology, and virtual reality.
From 'cybernetics,' coined by Norbert Wiener in 1948 from Greek 'kybernētēs' (κυβερνήτης, steersman, helmsman, pilot, governor), from 'kybernan' (κυβερνᾶν, to steer, to govern, to pilot), from PIE *kubernan (to steer). 'Cyber-' was extracted from 'cybernetics' in the 1990s and became a free-standing prefix meaning 'relating to computers and the internet.' A 'cybernaut' steers through digital space, just as the original 'kybernētēs' steered
