Can you imagine being Zuck? Super rich for basically creating the global gossip exchange and fraud factory, and he knows this, he knows Facebook is a clusterfuck of misinformation chaos. And he probably knows he is surrounded by yes people... I wonder if he knows he is in a nightmare.
I don't think it's a nightmare because he has choice and a fair amount of power. He could quietly retire comfortably if he wanted to, but instead he's making the play to reorient his company around a virtual-reality space. That sounds like a motivated person, versus someone trapped and going through the motions.
It's not always so obvious when you are trapped. How can we say he is acting truly freely, versus digging deeper?
Plot twist: Someone talked Zuck into VR as a step in playing some deep power-of-suggestion trick on him, as in the movie Inception.
Nobody thinks he's cool in this world, so he'll just spam "new worlds" until somebody thinks he's cool in one of them.
