This conversational disconnect is as old as the hills:

1. Person 1 asks "what's wrong" (if it ain't broke don't fix it)

2. Person 2 wants to make something better

My meta-goal here on HN (and many places where people converse) is for people to step back and recognize the conversational context and not fall into the predictable patterns that prevent us from making sense of the world as best as we can.
