What I'm not sure about is whether the problems that author mentioned were intrinsic to the software systems, or they were fixable. Many of the problems were caused by incompetent product managers, per the author's speculation. I was wondering if such incompetence (or malice for the sake of argument) is rooted in human nature and therefore can't be fixed, or companies can still iteratively remove such pains. If such problems are part of the human nature, then wouldn't they manifest themselves in other systems even if we don't use software?
