I cant say that yet because he is pushing car culture.. It would make more sense to make public transportation a truly reliable and viable option in the bigger cities. Id be impressed with that. The truth is most times people dont actually need a car but they default to is because mass transit is terrible everywhere in the US except NYC.Steve came up with some great tools, for sure, but IMO that tech path was already laid. SJ surely rushed it and also made it sexy and marketable. Musk makes tools too and the same could be said of him ushering in tech whose path was already laid. I would say Musks tools are much more impactful and less visible whereas SJ's tools are relatively simple but very visable and widely used by many people.
Battery technology is great but look where its going and all of these companies are trying to improve battery technology for their products. Apple was instrumental in improving battery tech in the computer world. Musk is just feeding off of the groundwork of prior tech companies including Apple. Space travel.... Hmmm that hasnt panned out yet. So... Sorry Steve >>>> Musk.
