There is no damn worldwide shortage of Cobol devs. There's a few localised, highly publicised cases where those devs are needed, those cases are diminishing fast, and that's about it.

Please stop touting this nonsense that everyone who learns Cobol can just drop into a job and make 6 figures. The only thing that's going to come out of this is a worldwide surplus of devs who learnt Cobol, and are now gobsmacked no-one wants to hire them to work in an antiquated language they have zero real-world experience in.
