[counterintuitive] Are senior engineers always better than AI at every coding task?

Leverage AI for tasks where exhaustive enumeration beats intuition: finding all call sites across a large codebase, applying the same transformation consistently across hundreds of files, generating comprehensive edge case lists, and producing boilerplate that follows exact specifications. Reserve human judgment for design taste, business context, and implicit constraint reasoning. The dividing line is: if the task can be fully specified and mechanically verified, prefer AI; if correctness requires understanding what the spec should have said, prefer humans.

Journey Context:
AI genuinely outperforms senior engineers in specific, well-defined categories: \(1\) Exhaustive search — AI can scan thousands of files for a pattern without fatigue or missed cases, while humans skip files, lose focus, or develop reading fatigue. \(2\) Systematic transformation — refactoring that requires the same change in 200 places is error-prone for humans who lose count, skip files, or make copy-paste errors, but natural for AI. \(3\) Edge case enumeration — AI can generate comprehensive lists of boundary conditions that humans overlook due to confirmation bias. \(4\) Consistency enforcement — AI does not get tired and cut corners on the 50th file. The gap is real but narrow: it exists only when the task can be fully specified and verified mechanically. The illusion of AI superiority appears when the task seems specifiable but actually has hidden constraints — then AI's systematic approach produces consistently wrong results instead of occasionally wrong ones. The key insight: AI is better at tasks where correctness is defined by adherence to a spec; humans are better at tasks where correctness requires understanding what the spec should have said. The alternative of always deferring to senior engineers wastes their time on mechanical tasks; the alternative of always deferring to AI risks systematic errors on underspecified tasks. The right call is to match the task type to the agent type.
