If you're going to be in the technology business in any way, shape, or form, and you have to get to the details. I thought I was good at that, and then I met Elon Musk. Holy crap. For him the details started at atoms. Maybe lower, I don't know. But like, what I thought was first principle thinking wasn't close to his first principle thinking, and then I got my ass kicked seriously about doing that. But it was really great, I really like to do that. I hope that when I engage with engineering teams, they start to get that engineering is fun, and the details matter, and there's an abstraction stack - there's the high level, there's the medium, and there's a low level. Yes, you do need to know a lot about all of them, because then you can figure out how to fix things. You can't fix something simple like ‘computer too slow’ - what are you going to do if it's too slow? If you could go into 1000 details, there's all kinds of stuff to do if you know the details.
