> Can LLMs do Cobol?

I imagine it's the one place where LLMs would absolutely shine. COBOL jobs are usually very verbose, lots of boilerplate, but what they do is mostly very straightforward batch processing. It's ripe for automation with LLMs.

The flip side is that banks are usually very conservative about technology (for good reason).

I don't think LLMs are anything human language specific, so would they really shine here? I.e, COBOL and SQL may be great for humans who otherwise aren't used to programming languages, but LLMs have seen everything, and thus are able to know any (programming) language, not just ones which are English-like.

IMO the ideal path to working on COBOL without having decades of experience would be to spend a few days groking the syntax and writing toy programs for practice, then collaborate with a large LLM to understand the current code and gradually make changes.
