As our referenced quote states in SFMZ's Sci-Fi Subgenres A to Z feature, Cyberpunk Sci-Fi is noted for its focus on "high tech and low life" and taking its name from the combination of cybernetics and punk. Cyberpunk often encompasses nanotechnology, androids, virtual reality, and/or a warning as to what could possibly go wrong if technology falls into the wrong hands. Humans may have built-in computer jacks or software, and spend considerable time "living" in a virtual environment.
Films released before 1984 should be seen as precursors to the genre. Cyberpunk Sci-Fi includes the following sub-sets, visit the SFMZ link above for their descriptions: CYBERSPACE SCI-FI, POST-CYBERPUNK SCI-FI, and BIOPUNK.
