I think if you a machinist/mechanical eng you possess this trait, you have almost all the tools to make other machines that make new machines, but this is is kind of limited to this one discipline, whereas software we can almost build anything. In a previous profession I learnt this great lesson where we would occasionally build specific tools for specific jobs if we didn't have the correct machines to save sending parts out to be machined or even for doing backyard jobs.
