"GitHub intends to store every public GitHub repository on film reels coated with iron oxide powder, which can be readable for 1,000 years using either a computer or a magnifying glass. Those who wish to add their code to the vault have until February 2nd, 02020 to do so. At that point, GitHub will take a snapshot of every public repository, and add it to the storage vault. GitHub plans to update the library every 5+ years."
