Cyberpunk
Cyberpunk is as much as a philosophy as it is also a theme used in fiction, fashion, music, and technological design.
The idea behind cyberpunk culminates from the idea that technology, philosophy, religion, intelligence, and human interaction will someday meld together in cyberspace, a digital realm created expressly for the purpose of hosting every aspect of your life virtually: meetings, conversations, games, emotions, communication, research, and so on.
The origin of the cyberpunk concept is usually credited to William Gibson, and his book Neuromancer, although other books have indulged into this concept and have defined particular realms within. The actual first appearance of the word "cyberpunk" occurs in Bruce Bethke's short story "Cyberpunk", first published in AMAZING Science Fiction Stories, Volume 57, Number 4 of November 1983.
Snow Crash by Neil Stephenson is probably the second-most referred to body of work that integrates the idea of existence in both the modern and highly commercialized real-life universe and a hacker-oriented metaverse where society continues as an extension of itself.
Visually, Ridley Scott's theatrical interpretation of Blade Runner (written by Philip K. Dick as a short story entitled "Do Androids Dream of Electric Sheep") gave birth to an environment ideal of the cyberpunk universe.
