There is an interesting rule from biological evolution of rates of extinction with species age that I&#x27;d thought of in relation to this. Essentially: they&#x27;re constant. That is, a species is as likely ro go extinct when old as young:  there is no increased survival probability with age.<p>Leigh Van Valen&#x27;s Law of Extinction, related to the Red Queen Hypothesis.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Red_Queen_hypothesis" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Red_Queen_hypothesis</a><p>I don&#x27;t know how well this translates to areas such as software, but it does give me pause.
