Yeah, fixing a problem without understanding it has some disadvantages. It works sometimes, but the "with understanding" strategy works much more often.

Is this really a prevailing attitude now? Who cares what happened, as long as we can paper over it with some other maneuver/resources? For me it's both intellectually rewarding and skill-building to figure out what caused the problem in the first place.

I mean, I hear plenty of managers with this attitude. But I really expect better on a forum called hacker news.
