Was thinking about how jobs mention "part of your role is to keep up with current technologies" or whatever, which kinda goes without saying because usually in IT jobs if you have to keep a service moving you'll end up using different, new components to maintain it. Or if you're unfortunate enough to work with shit like Kubernetes, they just keep breaking shit nonstop and you have to stay on top of it.
And I realized that if one DOES want an IT job where you literally just do the same shit for 10+ years, you need to be proficient in old, completely obsolete codebases. COBOL, RPG, Fortran, etc.
And I gotta admit I'm not 100% against the idea of, some day, committing myself to an eternity of mild pain (maintaining a decade's old codebase I didn't write) in exchange for superb job security (because there's always executives that will kick the can down the road for decades).
