The novelty with Gibson isn't technology. Asimov had Matrix-like learning in his novel "profession", so isolated concepts aren't the core of cyberpunk.
What makes cyberpunk is, IMO, a combination of capitalism and rapid technological advancement; technology that runs faster than legislation and which can be used and abused. Viruses, hackers, AIs... while authors like Asimov deal with ethical implications, Gibson shows us the legal holes that allow cyberpunk to take place.
