It's funny that you mention COBOL in your comment. It made the news for a few weeks in 2020h1 because many state-level Departments of Labor needed their COBOL systems updated to handle the influx of people put on unemployment due to the forced layoffs caused by state-level pandemic policies.
As much as we want to think that Python and pHp and Ruby on Rails and JavaScript are a must for programming systems in the 21st Century, the astounding quantities of COBOL systems used by governments and banks ensure that COBOL will be needed far into the future if for no other reason than program maintenance. Like World War 2 veterans, COBOL programmers are at fewer and fewer each day, and they will be paid a premium just to keep the systyems up and running.
Whatever species succeeds homo sapiens as travelers through space and time will discover that devices used for warp drive and stargate travel have some COBOL at their most fundamental level of functionality.
Unfortunately I was never that good at coding or debugging code, otherwise I might have taken that path. I remember it was one of the less annoying languages I had to learn.
