There’s COBOL stuff out there that’s as bad or even worse and COBOL programmers are dying off.

In the defense industry there was a major battle between the forces of the DOD developed language - Ada - and C++. C++ won by default because Ada isn't supported by anyone so you can't get tools for it. But a lot of DoD code developed in the 90s is still in Ada.

And nobody knows how to work in it anymore. Developers from 25 years ago moved on, moved up, or forget. So people have to try to learn it as they go and figure out what this complex software is doing on their own. Upgrading those systems costs a fortune just for that reason alone.
