I know some large financial institutions that still use it. They were building big systems using the stuff in the 90s and early 00s. It still works and nobody has the appetite to rewrite it as it's a massive undertaking that would be very expensive and high risk. Better to just keep updating it to support the occasional new requirement.

They'll rarely advertise it in a job listing of course. They're looking for people with Java/C#/C++/Python experience, and there's certainly plenty of that, but also thousands of little Perl scripts doing ETL workflows.
