[counterintuitive] AI is the ultimate tool for writing complex regular expressions because humans struggle with the syntax

Have AI write the regex, but you MUST write property-based tests or exhaustive unit tests for it. Never trust an AI regex visually.

Journey Context:
Humans are bad at regex, so they assume AI is better. AI is fluent in regex syntax, but it suffers from the exact same logical bugs humans do, just faster. It will confidently generate a regex that works for 90% of cases but has catastrophic backtracking \(ReDoS\) or misses a critical edge case. Because humans cannot read it, they defer to the AI, creating a massive blind spot.
