Science fiction author William Gibson confesses:
It’s harder to imagine the past that went away than it is to imagine the future. What we were prior to our latest batch of technology is, in a way, unknowable. It would be harder to accurately imagine what New York City was like the day before the advent of broadcast television than to imagine what it will be like after life-size broadcast holography comes online. But actually the New York without the television is more mysterious, because we’ve already been there and nobody paid any attention. That world is gone.
Charlie Stross illustrates how science fiction is increasingly indistinguishable from today's technology:
We used to read SF to get the heady high of a big vision, the "eyeball kick" as Rudy Rucker describes it, of seeing something brain-warpingly different and new for the first time. But today you don’t need to read SF to get a sense of wonder high: you can just browse "New Scientist". We’re living in the frickin’ 21st century. … Surgeons are carrying out face transplants. I have more computing power and data storage in my office than probably the entire world had in 1980. (Definitely than in 1970.) We’re carrying out this Mind Meld via the internet, and if that isn’t a 1980s cyberpunk vision that’s imploded into the present, warts and all, I don’t know what is.
