Zuckeberg overruled 18 quacks and snake oil salesmen. I don't know why media still bow before "experts" when obviously so few of them are.
It's unlikely that Zuckerberg is more of an expert on any topic, though, except perhaps BJJ. His educational background is literally just "briefly attended Harvard College."

How exactly do you determine this? On top of this how do we know you're not a quack snake oil salesman?
Are you a welness expert?
