This is the oldest tech still used by the US government

Agencies across the government reported using tech in some cases that was more than 50 years old, according to a new report from the Government Accountability Office.

That means everything from America's nukes still being controlled by 8-inch floppy disks to taxes being tracked with a programming language designed in the 1950s.

The title of the report on the government's information technology infrastructure - "Federal Agencies Need to Address Aging Legacy Systems" - is what we'd classify as an understatement.

Here are the oldest systems GAO found were still in use, along with the plan (if any) of when they'll be updated.
