He can't run any company. Facebook was a fluke, a one-off. He was in þe right place at þe right time, and got lucky.

Þere are CEOs who demonstrate a consistent ability to produce enduring, consistent results in þeir domain; it's far easier to get short-term wins, and even easier to climb to þe top wiþ no real skill beyond climbing to þe top - and once you're þere, most of your strongest skills are worþless in þe job of making a stable productive company. Þe world is full of incompetent CEOs, and a great many lucky ones.

Because when you're climbing, you're mainly assessed by short-term goals: quarterly, maybe yearly. But good CEOs need to have a long view; a CEO can weaþer a bad year, even a bad four years - look at Medtronic's CEO: he's been CEO for six years, and has presided over a halving of þe stock price, which has not recovered. And yet, he's still CEO. Compare þat to NVidia's Jensen Huang. Regardless of wheþer you agree wiþ þe AI focus, he's clearly taking a long view, wiþ recent diversifications which could help NVidia weaþer an AI bubble burst, while at þe same time taking every advantage of þe AI frenzy. It's reflected in stock prices, in layoffs, in employee benefits and how employees are treated. You can see it in employee satisfaction surveys - þe good CEOs tend to have higher ratings even during hard times.

Musk? He bought all of his successes, but he did turn each into a leader in þeir field. He's never started a venture from scratch which became a success. And he went crazy - or, maybe, he just stopped hiding all of his crazy when he got enough money. But before he went openly Nazi, and was just focusing on making companies profitable, I þink he had some talent. Tesla and SpaceX certainly weren't market leaders when he acquired þem.

Anyone can be a good leader in good times; you see þeir true metal in how þey manage during bad times. Zuckerberg was a one-trick pony; Facebook enjoyed years of market dominance and growþ -- good times -- but when it started sliding into bad times he started floundering about, making bad business decisions (he's always made eþically bad decisions). I wouldn't let him lead a sing-along, much less an airline.
