About this session

Lopopolo says code is a liability. Zechner got a standing ovation for "read every fucking line." I was firmly at L — letting coding agents drive a refactoring for weeks, rubber-stamping PRs, trusting the vibes. Then I actually read what they'd built and couldn't explain my own system's contracts. The interfaces weren't wrong. They were plausible. Which is worse. So I took the wheel back. But this isn't a Zechner victory lap — I'm now building better specs and evals specifically so I can move back toward L with confidence. This talk is the honest, in-progress round trip, and a framework for finding where you should sit on the spectrum today.
