I think you&#x27;re taking his point too literally. Yes, you can find a pathological interpretation of his words and beat that up. But his point is that most of the arguments people have here over language choice are irrelevant, because whether you&#x27;re using PHP or Python or Ruby or Scala or Go is not the bottleneck in the system.<p>Personally, I agree. I&#x27;ve never seen a bad team succeed because of a good language, and I&#x27;ve never seen a good team fail because of a bad one. We argue over languages not because it makes or breaks companies, but because that&#x27;s the most obvious feature of our days. We form tribes around languages the way non-programmers do around sports teams, and as with sports teams, minor differences get blown up into major social divisions. It&#x27;s our own version of the streetlight effect: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Streetlight_effect" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Streetlight_effect</a><p>I&#x27;m all for people arguing about language features when they are actually designing languages. But as far as building businesses around software, I think &quot;Language X is a secret weapon&quot; is absurd. If a good team picks something they&#x27;re happy working in, then the biggest problem with a project will almost never be the language they picked.
