LLMs are great at language. I often use them to generate syntax for a language I don't know and probably won't use again. While the short snippets may not do exactly what I want, I can edit a snippet fairly easily. Writing one with no knowledge of the language would take me far longer.

Just remember that being good at language is not the same as intelligence. LLMs are good at mimicking thought, but they cannot problem solve or optimise. You still have to do that bit.
