The Digital Dark Age

The digital dark age names a slow catastrophe hiding inside abundance. We have recorded more of human experience than any civilization in history—emails, photographs, video, the entire web, the administrative record of every institution—and yet the record is more fragile than parchment, because a digital file is not self-describing: it means something only to the right software running on the right hardware. A document written in a word processor of the 1990s may already be effectively unreadable, not because the bits have decayed but because the application that understood them is gone. Vint Cerf, who coined the term, has called this phenomenon bit rot: the bits survive; the ability to interpret them does not. The proposed remedy—digital vellum—would bundle a file with everything needed to read it: the application, the operating system, and a hardware description, all preserved together so a future system could reconstruct the original
