In case anyone is interested...
The SO Developer Surveys give some info on the job market for COBOL as it appears on the average salary versus years-of-experience graphs, which I like as there's as many stories or reasons as you can think of to explain them.
In 2023 there were 222 respondents who averaged 19 years of experience, and an average salary of $75,500. In 2024 the exact number of respondents is not shown, but likely similar based on the color code of the point, but the average experience had dropped to 17 years.
Elsewhere in the graph my favourite open question is: how come the over 2000 respondents mentioning Swift average over 11 years experience in a language that's only been public for 10 years?

iOS development has been around for quite some time now. Most senior iOS and Cocoa developers probably started with Objective-C before slowly migrating codebases over to Swift.
