If you are an experienced developer in general your code will in general be better than an LLMs even in languages you are not proficient. The LLM code might be more in keeping with the languages conventions but that does not make the code automatically superior. LLMs typically produce bad code in other dimensions.
That's hilarious LLM code is always very bad. It's only merit is it occasionally works.
> LLMs can produce better code for languages and domains I’m not proficient in.
I am sure that's not true.
