Originally, the so-called “information superhighway” was a metaphor. Information would still be flowing along telecom trunk lines, just like it had before. The amount of info available through those same old lines was the real story of the early 1990s. But fast forward a few decades, to a future imagined by Carter Baldwin and Simon Liu: there’s so much information that a highway can barely contain it. Miles and miles of high-speed cable, just below the actual roadway. I’m not sure what’s going on in the wild undergrowth beneath the infrastructure, but that doesn’t interest me nearly as much as the infrastructure itself. The tubes! The girders!
