Depends. A lot of the 1-2 sentence rapid responders from my past jobs weren’t really understanding the problem. They were virtue signaling that they were confident, fast to respond, and understood immediately (without elaborating)

It’s easy to send a pithy response that suggests experience and understanding without having either. Think of a middle manager spouting pithy buzzword laden cliches confidently in response to every request, then transferring the real problem to the grumbling employees who have to solve the actual hard parts of the problem which lie in the nuance.

This is a core problem of short-form social media (including HN): it’s easy to signal understanding or expertise without having to demonstrate it.
