From William Gibson: The Rolling Stone 40th Anniversary Interview [by Andrew Leonard]:
Totally ubiquitous computing. One of the things our grandchildren will find quaintest about us is that we distinguish the digital from the real, the virtual from the real. In the future, that will become literally impossible. The distinction between cyberspace and that which isn’t cyberspace is going to be unimaginable. When I wrote Neuromancer in 1984, cyberspace already existed for some people, but they didn’t spend all their time there. So cyberspace was there, and we were here. Now cyberspace is here for a lot of us, and there has become any state of relative nonconnectivity. There is where they don’t have Wi-Fi.
In a world of superubiquitous computing, you’re not gonna know when you’re on or when you’re off. You’re always going to be on, in some sort of blended-reality state. You only think about it when something goes wrong and it goes off. And then it’s a drag.
