Musk is only good at one thing, which is play investors like violins to generate hype and secure more investments for the company. The rest of the company's success is owed to the extremely competent and talented engineers and workers making those extremely ambitious projects a reality.
Every time Musk tries to pretend he's an engineer and tries to micromanage engineering and design decisions we end up with things like the Cybertruck.
I'm going to keep repeating it until it becomes common knowledge: When Musk stole the company from its original founders in a board coup, he specifically demanded that the cars have flush-fitting door handles despite his engineer's objections. Reinventing the door handles was excessively time and cost prohibitive because of the crash safety requirements involved but Musk would hear none of it. And it was. It nearly bankrupted the company early on and it was only saved by government grants from the Obama days.
That's the thing. Design implies engineering decisions. Decisions requiring huge amounts of expertise, talent and work. All Musk did is get in front of his lead engineers, handed a crudely drawn triangle on a piece of paper and said "It must look like this, make it happen". He did the easiest 0.001% part of the job of coming up with an idea for something that he thought looked cool and the rest was done by people who are far more intelligent and talented than him. And yet he is the one giving himself all the credit for it. This undeserved self-praise, stealing of credit (and wages) from other people's work and the sheer arrogant intellectual dishonesty of believing that he is as smart and hard working as those people who are actually making things happen is why I can't stand Musk.
The fact that the Cybertruck is a stupidly flawed, barely functional monstrosity with tons of production issues and insane price tag are side effects of all the compromises that had to be done to fulfill Musk's demands. It is literally Musk's equivalent of The Homer car from the Simpsons.
