Re: Q) How did Musk become a Millionaire?
The important point is that a lot of that pocket money was lent to him by other people.
Unless the principal condition of the loans was "Musk, you've got one month to permanently destroy Twitter's value, userbase and ability to function as an ongoing business", I imagine that Musk's secretaries are rather busy at the moment answering the phonecalls of some very angry bankers and oil sheikhs.
