It's more that if there isn't 10 stack overflows on your exact problem then you're out of luck.

LLMs are 100% useless for:

- non-mainstream languages

- langs without massive corpuses of online tutorials and SOs

I was going to add "langs without large online open-source codebases" but if they don't have extensive, reliable SOs (haskell, Solidity, even rust) then LLMs struggle to the point of uselessness, because LLMs don't actually trawl through random codebases and magically turn it into cookbooks and tutorials.

Indeed, an emergent problem with LLMs is they are going to recreate the 90s/2000s PL dark ages where "never write a new language" was mantra. Now it will be because a new lang can never hope to get sufficient LLM training data.

EDIT to your problem, it isn't the lang but the domain. If experts aren't dumping huge volumes of explanatory text online, an LLM can't help you even in a mainstream lang.
