These systems have not been running untouched for 60 years. Regulatory environments change almost constantly and the code has to be updated accordingly. I don’t personally know anyone writing COBOL but I’m certain there’s plenty of people doing it. And to change the code you have to know it. So there’s really no 60 year old code that no one knows anymore.
Also, at this point, if you are running on a dead platform and language and you know it, and haven’t addressed it, then it’s on you. I’ve been seeing these COBOL articles since the 2000s I believe.
