There's a joke about whether software engineers that write aircraft software would dare board a plane they've written software for.. I'm sure there's lots of places in skyscrapers and jumbo jets that the engineers in charge feel at least somewhat ashamed for, and are only there because they needed to "ship" and it was empirically shown to be "good enough" for practical purposes .. and then every once in a blue moon a plane crashes. Similarly to how debuggers help us beat code into doing something "good enough" for practical purposes, but no one really understands what the code does anymore .. and then every once in a blue moon there's something like heartbleed. Striving for perfection in a market context only sets you up for pain - since stakeholders rarely care about quality, they care about more money and less headaches now, consequences be damned. So everyone is just winging it.
