Cyberspace

"A year here and he still dreamed of cyberspace, hope fading nightly. All the speed he took, all the turns he'd taken and the corners he'd cut in Night City, and still he'd see the matrix in his sleep, bright lattices of logic unfolding across that colorless void."
– Neuromancer

Cyberspace has more literary origins. According to The Columbia Dictionary of Modern Literary and Cultural Criticism (1995) describes cyberspace as a “virtual world” that “is being developed through the interface of the human mind and computer technology. It is an electronically defined world in which a human can experience an environment completely outside the one that he or she physically occupies. The term was coined by the science fiction writer William Gibson in his novel Neuromancer, although his imaginative rendition of the concept is a good deal ahead of the technology presently available and more dystopian than most writing on the subject.
