There's a big discussion in there about the inherent requirement of labor, the definition of leadership, collective vs hierarchical decision-making, hegemonic inertia and market capture and more. This is probably not the best place to have it.

Not to say that Zuckerberg is dumb but there's plenty of ways he could have managed to get where he is now without having the acumen to get to other places he wants to be.

No one is rejecting the role of leader, it's just extremely exaggerated nowadays, like everyone thinks Facebook==Zuckerberg. And the leaders don't worth x1000 (or even x1000000 for some) unless they are doing a job of 1000 people. In most cases they are not even capable of doing 99% of the work people in their companies can do. Egomaniac Musk has already published his thoughts on programming problems, only confirming how dumb he is in this field.

There were dozens of social networking companies at the time that FB was founded. If Zuck didn't exist those same or similar workers would have been building a similar product for whichever other company won the monopoly-ish social media market.
