The most surprising part about this to me is that this matters at the top. Sure, for a middle manager it makes sense that it matters quite a bit. I'm pretty surprised that it matters much at the top, though. If Elon Musk decided to head a major grocery chain I wouldn't stop to consider whether his lack of experience in retail groceries mattered much. But maybe it does? Really interesting to see the analogy extend to…
Did Elon Musk have a lot of experience in self-driving cars or space rockets before Tesla?
In contrast, there's the "professional manager" archetype, who Musk is definitely not.
