Hmmmm. Tens of thousands of pilots are quite "absolute in their belief" that a landing gear failing to extend would be caught before landing. That gear is MUCH more complex, and the consequences of a failed gear MUCH more severe than a folding wingtip.
Similarly, tens of thousands of pilots are quite "absolute in their belief" that an assymetric flap extension would be caught and prevented before aircraft upset. The flap system is MUCH more complex and the consequences of a failed flap extension much more severe than a folding wingtip.
