As of today, "minor expert" is the wrong way to phrase it. The flagship LLMs today are at best at an initiate or apprentice level in every field.[1] This is not meant as a derisive remark – having something at hand that is initiate level in every field is remarkable and useful. But it's nowhere near expertise anywhere.

You seriously think current LLM is just at apprentice level in programming? It can write stuff one shot that I’d expected even some experts to struggle to do even with ample more time allowed.
