Do you respect MBAs?

Elon runs companies that are technologically innovative and lean with high IQ, self motivated teams. The first iPhone was made by just engineers too.

There are businesses however that need good execution over product innovation, a lot more caution and error prevention in their strategy and manage large people orgs.
These benefit from having a middle layer.

As per MBAs, quality does matter and many aren't as employable as they need to be.

Depends. I know a few superb MBAs who really excel at what they do. And their expertise helps me get my job done. But most of them they simply do Program Management under Strat, PM roles.

Elon Musk is an a grade chutia. Please read the exposes on how there are people whose main job is managing his childish behavior and antics at SpaceX and Tesla. The shit he has done at Twitter is another level entirely. That being said, MBA prepares you for operator work i.e. operating an already running enterprise efficiently. The rest depends on what you take from it.

Elon is living on another side of planet. His opinions not applicable much here.

Reality is companies are filtering out candidates without mba in almost anything and everything now.
