We now have Kerr’s Law (Interview)

November 4, 2026 · 2 h 27 min

Show notes

Dave Kerr created hacker laws, and now he finds himself reviewing agent-written code for them. Back on the show after six years, Dave names what he sees limiting teams today: keeping everyone’s mental model in sync with what’s actually been built. Adam declares it Kerr’s Law on the spot. We get into why Dave’s team treats code review as a deliberate slowdown, how Shellwright lets agents bring evidence to a pull request, and what living with bipolar disorder has taught Dave about noticing when the excitement of these tools stops being healthy.

Kerr’s Law — A team’s ability to scale is limited by its ability to keep a shared mental model in sync with the system it builds.
