I find these to be strange arguments. For example, the charge that he hasn't lived up to promises. What promises? The only really big fail that I'm aware of (and I've been watching the EV world and Musk since 2016) is his claims of self-driving. Everything else has not been a promise, but a goal. Sometimes people fail to reach goals on time, especially when they are the kinds of things that have never been done before. What "promise" has he made that hurt you or anyone else?

You have an entirely unrealistic set of expectations on the transition to electric vehicles. If you look at various projections from major organizations studying clean energy before Model 3 came out, they estimated less than 10% transition to clean vehicles by 2030 for new car sales. Then when Model 3 became a hit, they started bumping it up to around 25%. Now that every other manufacturer (except the Japanese) realized they need to go all-in on EVs in order to survive, the projections are around 50-60% EVs by 2030. That is a huge change, and it requires hundreds of billions of dollars of investment in new technologies and factories and supply chains across the world from dozens of companies. This is lightning speed for the largest manufacturing industry in the world!

SpaceX has transformed the space launch industry and is transforming telecommunications. Ukraine would have been right fucked if they weren't able to rely on secure high speed internet in the field from Starlink. Similar LEO constellations had been talked about for years, but because of the high cost of orbital launch before SpaceX, and general lack of urgency prior to Musk, it had never been done. Everyone else is still years behind, even after Musk lit a fire under them. We would be decades away from high speed LEO internet without SpaceX. It may not matter to you, but it matters to places without high speed cable around the world.

Is he an asshole who strangely wants to advertise that fact rather than hide it like every other CEO? Yes. Is he making a big difference. Obviously, emphatically, yes.
