Can AI Refresh Old Code?
Old code rarely fails all at once. It slows teams down in small, costly ways: long release cycles, brittle changes, outdated libraries, missing tests, and a shrinking pool of people willing to touch it. AI gives teams a practical way to improve these systems without rewriting everything from scratch. Used well, it can read large codebases, explain unfamiliar logic, suggest safer refactors, write tests, translate old patterns into newer ones, and help teams document what they already own.
