Why Did They Build This?

ThePrimeagen reacts to Zero, a new programming language from Vercel marketed as 'agent-first.' He argues the language offers nothing novel — it closely resembles Zig and Go, lacks any clear agent-friendly properties, and is verbose rather than token-efficient. He questions why a brand-new language with no LLM training data would be better for agents than established languages like TypeScript or Rust, which have massive existing corpora. He cites Odin creator Ginger Bill's take that designing languages for LLMs is like horoscopes — optimizing for something you don't understand.
