I'm willing to bet progress has accelerated at spacex since he kholed himself on twitter rather than interfering with daily affairs

It's his money that is funding it.

Well as he founded the company. So Not really. Same staff may have done similar for other companies. But it is hard to say the people would be together with the same goals without him.

But yeah. He is little more then money and bullying. His skill is non existant. And id be suprised if much of the corperate goals to reusable space flight are actually his. Rather then folks he paid to think.

I sorta imagine him walking into a room of random smart folks and saying. How much to go to mars. And letting others work the solution.
