The point of the analogy is that it is very easy to prescribe behavior that is guaranteed to work if followed 100% to the letter, but fails catastrophically if there is even 1 mistake. There are two responses to this - you can either design systems that are easier to follow &amp; fail less catastrophically in the real world (don&#x27;t use C for new code if you don&#x27;t need it; teach people about safe sex practices), OR you can double down on the sermonizing about how if people had just been smarter &#x2F; had more willpower, they wouldn&#x27;t be in this bad situation.
