“Fifty to ninety percent of the world's languages are predicted to disappear in the next century, many with little or no significant documentation,” according to Long Now. To save these languages, the foundation invented a rather ingenious solution. Embedded in a sphere of steel and glass, the “Rosetta Disk” is a physical disk containing over 13,000 pages etched with information on over 1,500 different human languages. The disk itself is made of electroformed nickel, contains useful information down to the nanoscale, was built to withstand multiple generations, and only requires basic technology to read—a microscope.That is, massive amounts of critical information stored away, no computer required. According to the Long Now website, the disk “serves as a means to focus attention on the problem of digital obsolescence, and ways we might address that problem through creative archival storage methods.”
