My job involves me sitting down with strangers, and reading their body language, responses, and political office needs and necessities to convince them to do something in my employer's interest. And I don't have a PAC or write campaign checks. It's all personality, emotional intelligence, preparation, and a little bit of luck. I'm fucking good at my job. I am hell of a lobbyist.
Along those lines: It's damn hard to be a good politician. It requires both physical stamina (they shake so many fucking hands), a thick skin, the ability to think on your feet, and being absolutely shameless, especially in asking for money.
You don't want me engineering your electric car, even if I can tell you where the lithium in it comes from and why renewable energy challenges aren't a mining issue, it's a chemistry issue. If Elon Musk came on board and said: I want to improve Twitter's algorithm and interface to improve it's user experience and drive eyeballs/clicks/revenue, I'd buy that. When he showed up and basically said: I'm going to be a giant personality/troll, well, let's say I'm doubtful.
