I took a mainframe class in college (2016) after my mom encouraged me to (she just recently retired as a COBOL/JCL developer of 35+ years). We learned COBOL and JCL on zOS and completed IBM's Master the Mainframe challenge. It was a very interesting experience and a different paradigm than any other CS/information systems classes I took. I could have gotten a job doing this work very easily. When I was applying and interviewing at my university career fair, I got a lot of interest and a couple job offers from having this class on my resume, but the pay wasn't good (small city it the south US that I wanted to leave), and I didn't want to lock myself into mainframes.
