Simon Willison Highlights Zig Creator Andrew Kelley: 'People from Agentic Coding Have a Certain Digital Smell'

Simon Willison surfaced Zig creator Andrew Kelley's quote on detecting LLM-assisted code contributions: 'It's a common misconception that we can't tell who is using LLM and who is not. The kind of mistakes humans make are fundamentally different than LLM hallucinations.' Kelley's analogy: 'It's like when a smoker walks into the room — everybody who doesn't smoke instantly knows it. I'm not telling you not to smoke, but I am telling you not to smoke in my house.' Reflects the growing tension between AI-assisted and traditional open-source contribution norms.
