Postulating about how things should be by non-experts has become a new e-sport. Then they try to apply it to software or startups as if its a apples to apples comparison.
In general, arguments by analogy tend to get hung up on the aptness of the analogy. I find it helps short-circuit a lot of long, unproductive discussions at work by just straightforwardly stating my thoughts—“we should do x because y,” rather than “system A is like system B (which does x because y), so we should do x.”
