GitClear’s Maintainability Gap analysis found that heavy users of AI coding tools increased their rate of code changes while code duplication increased and refactoring declined. Block duplication rose 81% over 2023-2026 (40.3 to 73.0 per million changed lines). As AI budgets tighten, teams are likely to face worse code maintainability and less usable ROI, pushing organizations toward stricter technical discipline rather than chasing raw output.
