In the 20th century, the genre imagined the body modifications and protective streetwear that could save us from our own future. Now it needs to envision humanity anew. CYBERPUNK IS LIKE cyberspace: instantly recognizable, but so ubiquitous as to be intangible. An aesthetic movement and a commentary on capitalism, it can be a genre, a subjectivity, an adjective, a political approach, a time period. (Though the same could be said of the words Renaissance or Victorian.) It can tackle artificial intelligence, embodied identity, digital immortality, or simply, in the case of Pat Cadigan's Synners, whether a marriage can survive electronic pornography addiction. Like the best fiction, cyberpunk still slips on like a pair of fingerless gloves, even if—in the 21st century, partially situated in the future it imagined—it's hard to see where fiction ends and reality begins.
