I know two people that spend some of their time writing COBOL for a major bank. They do find that part of the job pretty boring, it is basically just writing down SQL queries in a COBOL file and then trying to get passed their 50 year old development workflow (merge to master, then do testing in a testing environment, then get code review..).
I would love to do that for a living assuming it has job security, no crazy obsession with "velocity" and sane working hours.
