Well, the point is that it used to be the case that most of the people saying this sort of thing were those with an interest (oil companies, legacy auto, etc.). Now many other people are saying this too, because they can see blatant incompetence and failure and chaos on things they are familiar with. So they just happily assume everything else similar is the same. Just another Elon Musk
.
Elon is becoming quite toxic. By his actions unrelated to Tesla and SpaceX he's making everything that Tesla and SpaceX are trying to accomplish much harder. Now, every time a politician wants to support SpaceX or Tesla, they ask themselves whether it's worth it to be associated with Elon.
Maybe not yet a big problem for Tesla and SpaceX (which are well funded and successful), but what about his more marginal efforts like The Boring Company and Neuralink? They can be killed by a reluctance of politicians to support an effort tainted by pointless controversy. And TBC can do absolutely nothing without political support, usually in cities. This is bad, moving towards very bad. We investors need for Elon to STFU.
