alt Hacker NewsNo, I'm not.
I used to appreciate Lisp for the enhanced effectiveness it granted to the unaided human programmer. It used to be one of the main reasons I used the language.
But a programmer+LLM is going to be far more effective in any language than an unaided programmer is in Lisp—and a programmer+LLM is going to be more effective in a popular language with a large training set, such as Java, TypeScript, Kotlin, or Rust, than in Lisp. So in a world with LLMs, the main practical reason to choose Lisp disappears.
And no, LLMs are doing more than just generating text, spewing nonsense into the void. They are solving problems. Try spending some time with Claude Opus 4.6 or ChatGPT 5.3. Give it a real problem to chew on. Watch it explain what's going on and spit out the answer.

Until there is a bug and say due to DNS issues your LLM is. It reachable because everything is down
My hammer is also solving problems. Still, hammering is not programming. LLMs are text generators.

You are working on the assumption that humans don't need to even look at the code ever again. At this point it in time, it is not true.
The trajectory over the last 3 years do not lead me to believe that it will be true in the future.
But, lets assume that in some future, it is true: If that is the case, then Lisp is a better representation than those other languages for LLMs to program in; after all, why have the LLMs write in Javascript (or Java, or Rust, or whatever), which a compiler backend lowers into an AST, which then gets lowered into machine code.
Much better to program in the AST itself.
IOW, why program in the intermediate language like JS, Java, Rust, etc when you can program in the lowered language?
For humans, using the JS, Java or Rust lets us verbosely describe whatever the AST is in terms humans can understand, however the more compact AST is unarguably better for the way LLMs work (token prediction).
So, in a world where all code is written by LLMs, using an intermediate verbose language is not going to happen unless the prompter specifically forcibly selects a language.
