Yeah, he's just an idea factory. What's really remarkable to me is the breadth of his knowledge. I mean, I've met a lot of super, super smart people, but they're usually super, super smart on one thing. And he's able to have conversations with our top engineers about the software and the most arcane aspects of that. And then he'll turn to our manufacturing engineers and have discussions about some really esoteric welding process for some crazy alloy, and he'll just go back and forth. And his ability to do that across all the different technologies that go into rockets and cars and everything else he does, that's what really impresses me.
