I guess the difference here being that we have ample compiler literature and practically know 99% of all there is to know about compilers that exist in the wild vs this new field.

Until we’ve gathered and agreed on a few “dragon books” for LLMs and have explored all there is to LLMs, you’re probably right - know-how will be with the practitioners and in source code until it’s distilled (pun intended).
