Conway’s law still applies.

Good architecture, actor models, and collaboration patterns do not emerge magically from “more agents”.

Maybe what’s missing is the architect’s role.

The architect role is interesting because in practice that's what the "orchestrator" agent ends up being — but it hits the same limits as a human architect who's never on the ground floor. The agents that work best in my experience are the ones scoped tightly to a single concern (run this test suite, lint this file) rather than collaborating on shared state. Basically the microservices lesson all over again: shared-nothing works, shared-everything doesn't.

The architect’s role is what is left for us as developers, when putting out lines of code no longer matters.
