In reality, it's more like: any idiot can build a bridge that, in some places, is 5X as strong as it will ever need to be, in other places 2X as strong, and in a couple places only 0.8X as strong as it will ever need to be.
It takes the engineer to build it so that every part is 1.25X as strong as it will ever need to be, consistently everywhere.
To the idiot, that then looks like it is barely standing, because some parts are 4X weaker than he would have made them, based on bad intutition.
