The Long Now Foundation has developed a modern Rosetta Stone — a backup of human languages that future generations might cherish — etched on a 3-inch nickel disc with an estimated lifespan of 2,000 to 10,000 years.

The disc contains an archive of 13,500 scanned pages in more than 1,500 human languages with human-readable scripts, text, and diagrams (using a microscope). The plan is to replicate the disc and distribute them around the world in nondescript locations so at least one will survive their 2,000-year lifespan.
