[counterintuitive] AI code review can replace human code review for most bug classes

Use AI and human review as complementary, orthogonal bug-finding tools. AI catches syntax errors, anti-patterns, and known vulnerability signatures. Humans catch missing authorization, business logic violations, and implicit contract breaks. Never substitute one for the other — you lose the bug class the other is uniquely positioned to find.

Journey Context:
Developers assume AI review is a strict superset of linting, approaching human review capability. In practice, AI and human reviewers catch nearly orthogonal bug classes. AI excels at pattern-matching known issues \(missing null checks, off-by-one errors, known CVE patterns\) but systematically misses bugs requiring understanding of business intent. OWASP's \#1 vulnerability category, Broken Access Control, is precisely the class AI reviewers miss most: a missing authorization check looks syntactically correct but is semantically wrong. Humans catch this because they ask 'should this endpoint be public?' — a question about intent, not pattern. Replacing human review with AI review eliminates the bug class humans are best at catching, while AI adds coverage on pattern-based bugs humans gloss over. The combined coverage is multiplicative, not additive.
