I just reread Neuromancer and Count Zero, and the main thing I was struck by that Gibson didn't predict was today's omnipresent surveillance.
The people in his novels don't voluntarily carry around tracking devices and recoring devices. What they read and watch isn't tracked, and neither are their preferences or the opinions they express. They tend to have much more privacy than most people do today.
In this respect, I find today's society closer to 1984 than to Brave New World. It's 1984, complete with Newspeak, doublethink and Two Minutes of Hate for the boogeyman of the day, telescreens that combine televisions with security cameras and microphones what monitor what you do.
It's interesting that Gibson chose not to incorporate such dystopian themes in his books, and opted for what is in many ways a more optimistic dystopia.
