Ford's work with Edison allowed him enough time too experiment and he was not satisfied as technology and resources changed rapidly in that time frame. He moved on to newer possibilities and took advantage of his assets. His first foray into the auto business was not without problems but he learned.from that and very quickly moved on.
I'm relatively sure that he considered his first auto, the quadricycle, to be obsolete by the time he finished it. His first model A was simple but definitely more advanced than his first design. He had his sights set on the manufacture of an automobile for the masses and not just for the elites of society. Why sell thousands when you can make millions of them. He understood the way to business was to make more so that they could be made less expensive and let them sell themselves as a good low cost product. He was at the leading edge of being an industrialist.
I likely will never own a Tesla but it seems that Musk is becoming an industrialist even though he didn't really start out that way. We need more folks like Henry Ford in the future to bring the US back where it should be.
