Aside from what someone else said about Jobs being product, not marketing driven (just go google what he said when the org loses focus on product and the focus shifts to sales and marketing), you could argue it takes someone really good at X in order to be independent of X. For example, I am reasonably good at coding and ops. Therefore, most of the side projects I do are not constrained by coding or ops, but rather, e.g. my ability to design.
