No, what I'm digging at is that without a real definition of cyberpunk, pretty much ALL SF qualifies in one form or another. I feel like pretty much a purist in this area.
Cyber - involves cybernetics
Punk - Involves Punk culture

Wiki defines punk culture thusly: "The punk subculture is based around punk rock. It emerged from the larger rock music scene in the mid-to-late-1970s in the United Kingdom, the United States, Canada, Australia, and Japan. The punk movement has spread around the globe and developed into a number of different forms. Punk culture encompasses distinct styles of music, ideologies, fashion, visual art, dance, literature, and film. Punk also lays claim to a lifestyle and community.[1] The punk scene is composed of an assortment of smaller subcultures, such as Oi! and pop punk. These subcultures distinguish themselves through unique expressions of punk culture. Several subcultures have developed out of punk to become distinct in their own right, including hardcore, goth and psychobilly. The punk movement has had a tumultuous relationship with popular culture, and struggles to resist commercialization and appropriation."

Thus anything written before about 1970 is unlikely to involve both elements. And while I agree that Punk culture is somewhat about embracing the dystopic elements in our culture, I do not agree that a cyberpunk work, per force, needs to be completely dystopic.

By reaching for any SF with a dystopic gleam and having anything to do with information, you've just broadstroked over 90% of SF written in the last 3000 years.

e gads!
