Nothing says "legacy code" quite like a TODO comment from 1987 asking you to replace a COBOL system. The programmer who wrote that comment? Probably retired to a beach somewhere in 2005. The COBOL system? Still chugging along like it's got something to prove.
Banks and financial institutions are basically archaeological sites at this point. Somewhere deep in their infrastructure, there's a COBOL mainframe handling billions of dollars in transactions, held together by duct tape, prayers, and the three remaining people on Earth who can read the code. That TODO comment has watched empires fall, the internet rise, and JavaScript frameworks come and go every 3 months.
The best part? Nobody's touching it. Why? Because it works. And in programming, "if it ain't broke, don't fix it" is less of a guideline and more of a survival instinct. That COBOL system will probably outlive us all.
