Legacy COBOL code is largely used in critical systems like those of banks and airlines. What could go wrong with having that code rewritten by stochastic parrots who get programming answers wrong half of the time?
LLMs produce code that is functionally error prone while looking reasonable (in the same way that it produces answers that are grammatically correct, correctly spelled, but factually incorrect).
As we all know, fixing bugs in someone else’s code is generally more difficult than writing the code correctly in the 1st place , and that’s going to apply to a LLMs code output just as much as a humans, if not more.
That's assuming they're using one of the generic models like ChatGPT and not something custom they've created specifically to do this.
Edit: they are in fact using their own as per the article
I'm aware they're not using a generic model, but that's not much better. Current custom-made models still fuck up significantly more than humans, and in less predictable ways.
Even if their custom model is slightly incorrect 1% of the time, that's still a major problem in critical systems like those.
Which models are those?
I mostly use A.I. to translate. ChatGPT gets that done it gets it done pretty good, especially when you say “translate this mandarin text into English. I don’t care if it is somewhat inaccurate, just do it as best as you can.“
