One point I especially liked is that AI amplifies whatever architectural boundaries already exist. If contracts, external projections, and domain models are clearly separated, AI generates the repetitive mapping work quite well. If those boundaries are fuzzy, it happily optimizes them away because structural similarity looks like duplication. That's why architecture tests and module boundaries are becoming just as important as coding standards in AI-assisted development they teach the tooling what must not be coupled, not just what can be reused.
