I think he's made a major mis-step with twitter though.

SpaceX/Tesla employees work as hard as they do because they believe in the mission of the company. They're willing to just buckle down and do amazing things beyond most people.

Twitter had a lot of normal employees, however, it also already had the true believers in the mission. Those people don't seem to have bought Musk's vision and they're leaving the company. He wanted to get just down to those folks, but I think by and large, they're gone. I don't know that he can recover from that mis-step. He needed to come in, explain his vision and got the true believers onboard before he cleaned house IMHO.

I think more importantly probably all Twitter employees could find a similar job in 20-50 other companies in the area they live in. You cannot beat them up when there are still tons of employers willing to snap them up.

He must know this??

There a lot of tech layoffs and the market is nothing like it's been the last 15 years, so it's probably not going to be as easy as you think.

I could see working at twitter for the money or tough technical problems, but what mission could possibly convince you to work there?
