I mean obviously with a team of thousands of people, everyone is smart and working hard. But isn't it Elon who is deciding - yes/no I want to put tons of money and people into figuring out landing rockets, yes failures are acceptable, yes let's build a big f'ing ship to go to Mars, yes we're going to release a truck that looks like an oragami DeLorean and give it a crazy name CyberTruck, yes we're going to let you play video games in your car. And now, everyone gets a blue check mark!

You can have the best engineers in the world, but if the person at the top wants them to build a car that looks like Homer Simpson designed it then the company is going to fail. And that's Elon's role - make decisions all day long. Engineers give him options, cost/risk trades, etc.. and he has to make the right decisions that won't lead to bankruptcy. Tens of thousands of jobs on the line if the wrong decision is made.
