Why Code is Inherently Suited for Agents
fchollet · x · 2026-07-15
Chollet quotes Levie's view: the reason code is particularly suited for agents is that it can be rapidly tested. You can manually run an app or directly use tests to verify the build.
He points out that many other jobs lack this "instant testing" advantage. In areas like closing deals, signing contracts, or doing sales demos, you often don't know the outcome until the final real-world delivery. In the future, a whole new set of methods could emerge to extend this testability to more jobs, meaning agents will embed themselves deeper into various workflows; at the same time, the vast majority of scenarios will require better evals.
