Social Security systems contain tens of millions of lines of code written in COBOL, an archaic programming language. Safely rewriting that code would take years—DOGE wants it done in months.
My father-in-law is one of the last COBOL experts. Before he retired he spent 15 years training 3 people in COBOL so the business he worked for would not collapse. COBOL is irreplaceable and it is not being taught in any school in the USA.
