Cyberpunk is a literary genre that came to the forefront in the 1980s, typically characterized by protagonists living in tech-saturated hyper-real near-future worlds that had avoided self-annihilation and were in the process of reinventing themselves. See the Wikipedia entry on Cyberpunk for more info, but know that the Wikipedia entry’s assertion that cyberpunk is “dystopian” is considered by many to be wrong. Cyberpunk is not a dystopian genre, it came from a time of nuclear threat and told stories of a world that did not end in a nuclear holocaust. Cyberpunk is a genre of hope, as expressed by genre author Bruce Sterling in many interviews and a particularly engaging 2019 SXSW speech. There is a great deal of literature in this genre, and to understand it best, one should generally start reading the source material.
