Thing is, you can't take Neuromancer out of the '80s. The newness of computer networks, the ascendancy of Japan, the aesthetics of computer hardware -- boxy, whirring things with stark, green CRTs spewing masses of indecipherable alphanumeric incantations, big clunky cables, heavy briefcase-size mobile units; it's all there. And the mash-up of digital and analog technologies is no less integral than Gibson's opening lines to the book, comparing a halogen-hazed night sky to the analog noise of TV transmission.
Neuromancer didn't arrive into a world comfortable with computer technology like ours today. The book stands as a fantastic trip back into a time when technology could be dark, dangerous, and foreign, a zeitgeist Gibson leverages to dazzling effect. "Updating" Neuromancer would bring its entire shadowy world out into the unthreatening, mid-day sun.
