Zuckerberg is proof you only need to get really lucky once. He's basically flailed at leading facebook ever since, going all in on monumentally dumb bets and erratically making headcount and project decisions, and still he somehow keeps getting richer.
Just a stab in the dark, but it's likely because FB and meta are wildly successful businesses, and it's almost impossible to attribute that to one "lucky" event at the inception of the business.
If I'm being honest I'm actually kind of shocked at the engagement this comment is getting and the fact it's still visible. Like him or not, if you're capable of being objective, he is doing the opposite of failing...
