Haven't yet updated your Mac to the latest OS? Well, your tech is still way more up to date than the US Department of Defense's old-ass system. It's still using floppy disks.
As revealed in a report from the Government Accountability Office, the US Department of Defense currently uses floppy disks, as in the ones popular in the mid-1970s, to coordinate the nation's nuclear forces. That's right. The Department of Defense is even more behind the tech times than your dad, or maybe even your grandpa.
The description of the Department of Defenses's system from the GAO report reads as follows:
"This system coordinates the operational functions of the United States’ nuclear forces, such as intercontinental ballistic missiles, nuclear bombers, and tanker support aircrafts. It runs on an IBM Series/1 Computer—a 1970s computing system—and uses 8-inch floppy disks."
