Something to keep in mind, while Elon is SpaceX CEO/CTO, and does have influence over the company, the operation has changed greatly over the last decade. He does not finance the company in any form.

The day to day engineering is done by hundreds of much more qualified people. The man splits his time between a bunch of different organizations, it’s an impossibility that he is responsible for anything you are seeing happen today, in much the same way a retired football players commentary on todays game has any influence on its outcome.

It wouldn’t be completely surprising if one day he and his brother are ousted by the board of one of these companies.

Self landing rockets is a great thing to cheer about!

But also people cheered for a guy eating cheese balls so you may have a point.
