From a William Gibson blog post that links back here:
The thing that's going to be quaint about "cyberspace" (that already is, really) is the inherent assumption that it's a realm unto itself; that it's in any way elsewhere or other.
Glancing sideways is becoming more generally recognized as about the best way of doing what we used to call futurism.
At the risk of making this too tightly interconnected a thread, I'll note that Gibson's well-known quote that "the future's already here, it's just unevenly distributed" (also sometimes rendered as "not evenly distributed" or "not uniformly distributed") is engraved n the memory of every futurist. Especially since we started using ethnographic techniques in our work, studying early adopters for clues as to how the rest of us would use currently-new technologies.
