There's this rather sad thread from a decade back of cobol developers discussing being stranded after the jobs dried up.

All this talk about Cobol and nothing about it's characteristics that make it truly remarkable: all memory is statically allocated, there is no dynamic memory allocation. Makes streaming xml processing a true nightmare, but also make Cobol applications immune to entire classes of security vulnerabilities and exploits that plague every other language. Also, make performance reliable and easy to reason about with none of the "departures" common in other runtimes (ie thread pool exhaustion, stack overflow errors, heap exhaustion errors). Really dependable from a day to day management perspective.
