Yes, but productivity and efficiency are for nature, yes? Something it seeks to maximize over time; 'seek,' of course, not being the correct word, as it has no true intent. I do not think these things are in human nature as a priority. One ought not cease speaking, either, simply as others think one is wrong. If you tire of it, then that is one thing. Another is to shut up because of the voices shouting you down. Who cares?
