Edison is a better bet for this question. He made most of his successes by trial and error, until the failures ruled out all the stuff that wouldn't work leaving only what would. Plus, a significant portion of his accomplishments happened to be...."appropriated" from others. People act like Bill Gares is a genius, but he was great at assembling a team of top software writers and "getting there first" with an OS that became the de facto standard. He offered Internet Explorer for free with Windows, which really undercut Netscape's market share because they charged some nominal price.
