Eh. Whatever. I honestly don't care what language I work in.
I'm not sure that Pascal was ever significant enough to become obsolete. It was intended as a teaching language. It got used for a variety of things anyway, but was replaced by better languages before it got much traction.
I'll write COBOL, Fortran, or Pascal -- or Algol or Snobol or Logo. I don't mind legacy systems; I don't often get a chance to clean-sheet things.
The fact that those dead languages are running on either decrepit computers, or emulators for decrepit computers, that is less fun. Ideally, you'd be there to work on a plan to replace it with something more capable, because otherwise your project is permanently hindered by the original hardware.
But meantime, I'm perfectly fine keeping something running just because people need it to keep doing its job. If they can't afford to pay for an upgrade path, that's worrying, but only because they can't afford to pay for anything. Ya gotta spend money to make money.
Languages just don't make much difference to me. Frameworks make a bigger difference -- and yeah, for older languages, framework and language are pretty much the same thing. But all I want from a framework is to get the thing to do its job. The rest is just programming, and I'm happy to program. The fundamental problem-solving skills apply regardless of the language.
