Episode Details

Static type checkers are often sold as silver bullets for code quality, but the landmark 2017 study by Gao, Bird, and Barr found they catch only about 15% of public JavaScript bugs. This episode climbs the operational ladder of gradual typing — from two-tier configs and per-module ratchets to the human decision points where automation stops. We explore why AI coding agents make escape-hatch counters essential, how production type tracers produce raw material that still needs human judgment, and why runtime validation with Pydantic or Zod at trust boundaries is non-negotiable. If you've ever wondered whether your type checker is buying you real bug prevention or just expensive autocomplete, this episode walks through what the data actually says.
