It's not just software - it's engineering design in general. The hardest part of engineering design to know what needs to be built. This is akin to knowing the right problem to solve but engineers are trained poorly for that. For 4 years, we're given problems to solve so we get very good at that but that's very different from knowing what problems need to be solved for the project, which is essentially what writing requirements is.
