[counterintuitive] Should I trust AI or humans for large-scale mechanical refactoring

Use AI for mechanical refactoring \(rename, move, update imports, apply consistent pattern across many files\) but verify with compilation and full test suites; use humans for refactoring that requires architectural judgment about when the pattern should vary

Journey Context:
When a human applies the same change 50 times, they introduce variations — a missed rename, an inconsistent import path, a slightly different pattern on line 37 because they got bored. AI applies the same transformation consistently across all sites. This is a genuine advantage. However, AI does not understand when the pattern should vary — when one call site is architecturally different and needs a different approach. The refactoring taxonomy distinguishes between mechanical refactoring \(rename method, extract interface\) and judgment-based refactoring \(replace conditional with polymorphism, change bidirectional association\). Use AI for the former, humans for the latter, and always verify with build plus test.
