COBOL legacy systems in finance and government are somewhat of a meme. However, I've never actually met a single person who's day job is to maintain one. I'd be curious to learn what systems are you working on?
I met a dev who's mom had been working on legacy banking systems her whole career. She had started in the eighties and she still did some urgent jobs at a crazy rate despite officially having retired.
My mother used to teach Cobol back in the 80’s in Brazil but later she transitioned into management and haven’t touched a line of code for more than 30 years, she can’t even speak english wtf
