INTERVIEWER
What’s wrong with cyberpunk?
GIBSON
A snappy label and a manifesto would have been two of the very last things on my own career want list. That label enabled mainstream science fiction to safely assimilate our dissident influence, such as it was. Cyberpunk could then be embraced and given prizes and patted on the head, and genre science fiction could continue unchanged.
