[counterintuitive] AI code review catches the same bug classes as human review

Always have humans review concurrent and parallel code, state machines, and code with complex temporal invariants. Use AI for sequential logic, style, and pattern-based bugs. Never rely solely on AI review for code involving locks, async/await, message passing, or shared mutable state.

Journey Context:
AI models reason about code sequentially: they trace one execution path at a time. This is fundamentally inadequate for concurrent code, where correctness depends on all possible interleavings of multiple execution threads. A human reviewer mentally models 'what if thread A is preempted here and thread B does that?'—the AI typically traces one path and declares it correct. This is not a minor gap; it is a complete blind spot for entire bug classes: race conditions, deadlocks, livelocks, and memory model violations. The AI will confidently approve concurrent code that has subtle but catastrophic race conditions because it never runs the interleavings in its head. OWASP identifies race conditions as a fundamental vulnerability class, yet AI review systematically misses them. This is one of the clearest cases where AI code review fails catastrophically while appearing competent—it will find the missing semicolon but miss the data race that causes production outages.
