>> I would challenge you to name any (non-simple) problem where traditional AI methods are still state of the art.

Theorem proving, classical planning, SAT solving, robotics, search, in particular adversarial search, program induction, knowledge representation.

Plus all the stuff that used to be considered "AI" but aren't anymore, like rule-based systems (e.g. for fraud detection) etc.

Sorry, I know you asked for only one.
