[counterintuitive] Can AI code review replace or match human code review for bug detection?
Use AI code review as a fast first-pass filter for style, known anti-patterns, and common vulnerability signatures. Require human review for business logic correctness, state machine invariants, cross-component interactions, and any code involving money, security, or data integrity. Never let AI-only review be the gate for high-stakes changes. Track which bug classes each reviewer catches to identify systematic blind spots.
Journey Context:
AI code review tools are impressive at catching certain bug classes: unused variables, common security anti-patterns, style violations, and known vulnerability signatures. This creates an illusion of comprehensive coverage. However, AI systematically misses entire categories that humans catch: \(1\) Business logic errors—code that does something reasonable but wrong for the specific domain. AI doesn't know what the code SHOULD do, only what patterns look normal. \(2\) State machine violations—transitions that are locally valid but globally invalid. \(3\) Cross-component interaction bugs—each component correct in isolation but their interaction creates failure modes. \(4\) Missing error handling for domain-specific edge cases. The dangerous part: AI's competence at catching easy bugs creates a false confidence that reduces human reviewer diligence—reviewers see 'AI already checked this' and skim rather than deeply engage. This is the automation complacency effect: the better the automated system appears, the less carefully humans monitor it, right when careful monitoring matters most.
