The scary part is, if you went to a selective enough school, it kinda works.
The Ivy League undergrad -> elite MBA -> management consulting -> C-suite pipeline is especially frightening.
The worst in my opinion is finance-- it's like driving using the rear view mirror. No business has ever succeeded or failed because their accounting was really tip top.
People would laugh at the idea of a good leader being thrust into a SWE role based solely on their leadership skills. Yet we often think transitioning from a SWE to a leader is just picked up. I'm asserting that they are different skillsets. Will being a good developer help lead a team of SWE? Absolutely, but that alone doesn't provide the requisite knowledge and skills to perform a manager role, but we often think that's the bulk of what's necessary.
