Ex-Meta's Christoph Nakazawa on the Engineering Values That Still Matter in the AI Era
cnakazawa · x · 2026-09-26
Christoph Nakazawa (ex-Meta, Jest creator) reflects on which engineering values survive now that he rarely writes code by hand. His recent work is nearly all AI-written: Rust features in Vite+ (90% AI), fate 1.0, Codiff, and Athena Crisis updates (100% AI). He argues agents now match or beat his own code in minutes instead of weeks, making coding no longer the bottleneck. Values that endure: strong ownership, taste, strict guardrails with fast feedback loops, context in the repo, owning your stack, and option-value thinking.
