[counterintuitive] Can AI code review replace human review for catching all bug types?

Use AI code review as a fast first-pass filter for style issues, known anti-patterns, and obvious bugs. Mandate human review for: race conditions, business logic violations, error handling edge cases, violations of implicit invariants, and any code where correctness depends on understanding intent beyond what is written.

Journey Context:
AI code review tools catch many bugs that humans miss \(unused variables, common anti-patterns, style violations\), creating the impression they are a comprehensive replacement. But they systematically miss entire bug classes that humans catch. The key distinction is reasoning about INTENT versus reasoning about PATTERN. AI detects whether code matches known patterns; humans reason about whether code does what it SHOULD do. Race conditions require reasoning about concurrent execution order—AI sees sequential code and cannot model the interleaving. Business logic violations require understanding what the business rule is, not just what the code does. Implicit invariant violations require knowing constraints that exist in team knowledge but are not expressed in types, tests, or comments. AI code review also generates high false-positive rates on style issues, causing alert fatigue that makes developers dismiss its genuine catches.
