> If a bank is still using Cobol, it is interesting and a testament to how a Cobol programmer can still make a good living on it. But if a scientist is using Perl to carry out calculations, this is somehow bad?
Yes. The negative externalities of doing scientific analyses in Perl are much greater than a bank having a legacy COBOL codebase. Only a handful of engineers within the bank will ever see that COBOL codebase. Science is globally collaborative; many people at many different institutions across the world would have to deal with some idiosyncratic scientist’s decision to write their analysis in Perl.
Also, the bank only has a COBOL codebase because it’s reluctant to make major changes to an extremely important system that’s been working flawlessly since the early 60s. There’s absolutely no reason to start a totally brand new project in Perl (or COBOL, for that matter), when far superior alternatives exist.
