Serious question. Is there anything in Detroit's location, natural attributes, history that would have allowed it to become a major US city without Henry Ford and the auto industry? If Henry Ford had been born in Des Moines, Iowa would Detroit have been anything but a small/medium-size city and would be talking about the demise of the once great and powerful city of Des Moines?
I ask because looking at its population history, there was no indication prior to 1890 that the city was on a track to become one of the top 5 or 6 largest cities in the country.
