Yeah, but that's kind of how human progress works. For each Edison or SpaceX which successfuly commercialised a technology, there are Nicola Teslas and Apollo programs which did it way before both the tech and the society were ready for it, in a one-shot way that's a bit difficult to replicate.
What did Tesla do that was so far ahead of time that was difficult to replicate? Surely Tesla, together with Westinghouse, is why we have AC power distribution and polyphase AC motors and neither of those things are difficult once they are properly described.
