I have literally never heard Elon mention another person who already worked at the company. I can find plenty of times he was announcing a key hire, like when they brought in Peter Hochholdinger. Every new feature, product, etc is announced by Musk. Which like you said is similar to Apple. I think similar to Jobs, Elon is at least significantly involved in a lot of details - and I think similar to Jobs he feels that since he was involved it wouldn't have happened without him.

Google isn't a good example in my opinion though, generally people besides the CEO announce their products, i.e. Google Maps was announced by Bret Taylor. Look at the history of Google and Microsoft and you will see tons of "xxx announces/introduces yyy". Tesla's entire history is "Elon Musk announces ..." (after teasing on Twitter for 5 months to keep the stock price up).

I don't think everything is bad about him. I think the thing he is amazing at is setting the vision for his companies - which is really valuable. It really seems like everyone understands the mission and where things are going and he's very clear about it. So I think he has good qualities, I just think he's also narcissistic, financially impulsive and unfocused.
