You answered a question that the user didn't ask. If you feel they won't be around, that's fine. But if the discussion is about how hard drive usage will scale over many years, injecting "it won't matter" is a pointless comment. It not only doesn't answer the question, but it provides basically no information other than your feelings on a subject. It's exactly the thing I come to HN to avoid.
