LLMs make language choice less consequential, pushing devs toward Rust, Zig and harder tech

Fast and Hard Code

Armin Ronacher notes that LLMs erase the friction of learning a language, so devs increasingly pick based on speed marketing. Rust is gaining, and Zig appears in Cloudflare Artifacts (a ~100 KB Wasm Git engine) and Vercel fx, both LLM-assisted. Harder tech like DWARF, eBPF and custom crypto is now accessible to more people. His take: more slop, but also more devs who want things fast and small.

Why it matters: Armin Ronacher's observation is backed by named projects, not just vibes. The core insight—LLMs lower language-switching cost—isn't new, but he traces a downstream effect: devs now pick languages based on speed marketing, and Rust/Zig benefit. Missing piece: how many actually ...
