[counterintuitive] AI is more accurate on popular, well-documented libraries than on obscure ones

Always verify AI code using popular libraries against the specific version you are using. Treat AI confidence in popular APIs as a high-risk hallucination vector.

Journey Context:
Humans are overconfident in unfamiliar territory and careful in familiar territory. AI is the opposite. It is systematically overconfident in highly familiar territory \(popular libraries\) because it has seen millions of variations, including deprecated ones. It will confidently mix API patterns from version 2.x and 3.x of a library because both are heavily represented in its training data. For obscure libraries, it often hallucinates entirely, which is easier to spot than a plausible but outdated API call.
