I built a programming language that LLMs can't use

A language intentionally designed to be hard for LLMs to write. Fun experiment, but is there any real use for it?

Can someone explain the anti-LLM language like I'm five? Feels like I missed a few chapters.

Tried something similar last month. The practical results were mixed. Setup was okay, but edge cases killed me.

Underrated take: the anti-LLM language matters more for small teams than big companies.

the real question with the anti-LLM language is who maintains it in two years

Skeptical but curious about the anti-LLM language. Anyone got actual numbers or just vibes
