My gut feeling is, this post is 180° wrong. LLMs are the exact opposite of "elite coders", they're perfect StackOverflow users:

* they memorize adapt and write back small-scale patterns very efficiently; * they know widespread libraries inside out, and can learn others in minutes, even if their doc sucks; * they often produce good results, because most of the time we write unoriginal code, which paraphrases something it already has dozens of versions of in their training corpus; * but they're bad at seeing meaningful, non-obvious, simplifying abstractions, we really have to spoon-feed those to them; * they _love_ verbosity, that's literally how they "think"; * they also love repetition: the other term for "repetition" is "patterns", and they're basically excellent pattern matchers.

So, Lisp is enjoyable for your typical LLM-complementary hacker, but not for LLMs. LLMs typically replace the kind of "non-elite" developers who hated Lisp, for remarkably similar reasons.

What I'd love would be an LLM trained to faithfully rephrase a "normal" program into Lisp-ish pseudo-code, that would make reviews faster, more reliable, more enjoyable. But hand-written code is going the way of hand-written machine code; let LLMs have what suits them best, and higher level tools for the more abstract jobs where we're still relevant, and that would be various forms of code reviews.

As for calling "elite" the kind of developer won't understand that development is a team sports, and that the proper tool is the one that fits the team, not their own peculiar quirks, I'm not going to address that, it isn't the keystone of his argument; but a lot could and should be said about that too.
