> an LLM does not care whether your codebase is Java or Clojure. It cares about the token efficiency of the code, the structural regularity of the data, the stability of the language's semantics across releases.

Huh? All current and previous-gen models are most effective when coding in languages with the most test data.

While I agree the newest frontier model may be smart enough to reason at a lower level and be agnostic but its “relatively dumber / less capable” forebears .. need lots of examples to pattern match from.

Familiarity once again!
