Cyberpunk is a subgenre of science fiction in a dystopian futuristic setting said to focus on a combination of "low-life and high tech". It features futuristic technological and scientific achievements, such as artificial intelligence and cyberware, juxtaposed with societal collapse, dystopia or decay. Much of cyberpunk is rooted in the New Wave science fiction movement of the 1960s and 1970s, when writers like Philip K. Dick, Michael Moorcock, Roger Zelazny, John Brunner, J. G. Ballard, Philip José Farmer and Harlan Ellison examined the impact of technology, drug culture, and the sexual revolution while avoiding the utopian tendencies of earlier science fiction.
