Ask HN: What is the best non mainstream programming language or stack in 2026?

Out of curiosity I started developing in lisp, mindblown. Basically big language like Java, Javascript, C#, Python have a lot of momentum compared to more niche, academic languages like LISP, SmallTalk, Erlang, Haskell.

What is your experience with these languages in the era of LLM, where you now is able to create libraries on demand and better tooling ?
