Jarvis has a cure for curmudgeons

He says ignore them.

You see, the problem with curmudgeons and complainers is that its so easy for them hijack any discussion. For not to deal with their very grave concerns is to make you look careless. That’s the rhetorical trick: “You could be wrong, it could go wrong, answer me that!” And if you don’t? “Aha!” Well, the hour is far too late and the state of the industry far, far too desperate to waste time with these sideshows. They had their time and the objections needed to be addressed in that time. But I haven’t heard fresh objections in a few years. What I want to hear instead is fresh ideas; we must have more of those.
