I agree with the thrust of your argument but its actually still totally a social and economic problem and not a problem of technology. First covid19 demonstrates how much of education and work can take place from the home without the need of rushhour style transport. Second your examples of gates and musk are actually examples of the general failure of governments and markets to use existing technologies. Nuclear power, Hydro electric, ocean power, traditional solar ; all of these are existing technologies that dont need innovation what they need is the economic and social Will to construct. Musks EVs ; very expensive direct replacements for existing vehicles to me indicates something very wrong in the approach to solving climate change. The problem is one of Coordination. The sclerosis of western society and our focus on individual incentive prevents anything but the most marginal of improvements. A great example can be seen here in Ontario. Here the government subsidized private individuals to put up their own solar on their homes. Electric prices soared. The result is basically a wealth transfer from poor to rich with very little gained. Again there is some similarity here to the Tesla EV. Not that solar makes much sense in Canada but i am sure the government could have done much better to have run this project itself.
