I think the difference in [0] is your input variable space is much smaller for "traditional" engineering disciplines. To grossly simplify: ME? You need tolerances for a specific amount of force (in different directions.) EE? You need tolerances for specific amounts of current passed through a circuit. With software your inputs are tremendously varied, because user input is not as well-formed as in any other engineering disciplines. In fact we deliberately try to find ways to input things that are not supposed to be inputs by designers of systems (i.e hacking things). If "hacking" bridges was a thing, it would be something like people trying to see if they can diffuse a thermite solution into the rock-face instead of driving a car over it, and I'm not sure any structural engineer has planned for that scenario.
