It’s nightmare for developers if you get stuck with infrastructure on such dinosaurs and need to deploy a fresh new project. Anything made in the last 3-5 years likely won’t build due to at least openssl even if you get it to otherwise compile. Docker may not run. Postgres may not run. Go binaries? Yeah those also have issues. It’s like putting yourself into a time capsule with unbreakable windows - you can see how much progress has been made and how much easier your life could’ve been, but you’re stuck here.

Old systems are stable, but there’s a fine line between that and stagnation. Tread carefully.
