Ah, the rare 'HN person who knows more about everything than everyone', what a joy to see one in the wild.

If you're getting bad troubleshooting it's because you're going to places that value moving units (people) as fast as possible to pay the rent. I assure you neither most mechanics nor most doctors are 'the worst debuggers in humankind'. There are plenty of mechanics and doctors that will apply a 65% solution to you and hope that it pays off, but they're far from the majority.
