While you're correct on the one hand, Tesla made EVs feasible and mainstream, did the investments and caused a rolling effect of worldwide investments in e.g. batteries and EVs, and government subsidies that also made investing in EVs more attractive to competitors.

Besides EVs, Tesla's long term revenue could very well be in the supercharger network, too. It's not as exciting as self driving cars, but the oil companies have been the most valuable companies / stocks worldwide without being exciting like that. I mean I don't think EV charging will be anywhere near as big as oil because it doesn't involve nearly as much infrastructure or international trade, but it's still big, especially if governments refocus on replacing ICEs with EVs.

(the focus has been let go because the subsidies were too popular and expensive)
