This is what happens to people that become wealthy later in life, as opposed to inheriting it. The critical difference in the two is when you're inheriting a large amount of wealth you're also inheriting the social connections that go with it, and this has a normalizing effect on your attitudes and beliefs. But when you are Zuckerberg, First Of His Name, you don't have that network... and you're not going to develop it for many years, assuming you even realize its importance.
Yes, I'm well aware that the man "invented" (gigglesnort) social networking, but as anyone can attest... Facebook is not real life. And if you don't get social development with real people, in the flesh, to help normalize your attitudes and behaviors, you're going to becoming increasingly disconnected and neurotic. This isn't even limited to humans: Separate any social animal from its pack or social grouping, and it'll quickly start exhibiting irrational, even self-destructive, behaviors. And while yes, humans do interact with each other nearly every day, it's the quality of that interaction that matters: Wading through a crowd of strangers or going to the bar isn't developing substantial relationships. If that sounds familiar, it should: It's become the norm for people to have hundreds, if not thousands, of Facebook "friends". Sociologists peg the number of substantial relationships a person can have as around 250. Facebook is the social equivalent of junk food... it's unhealthy in more than small doses. If you try to live on it for all your social interaction... I hope someone hands you a mirror so you can bend over and properly kiss your ass goodbye.
Zuckerberg has fallen into a very well-prepared trap of his own making, and this is the outcome of it. He'll continue to become more eccentric with increasingly warped ideas about how the world is, due to a lack of significant social interaction with his peers. It's happened many, many times to wealthy people. Look at people who win the lottery as just *one* example: Most of the time it ruins their life and within a few years they are *worse* off than before!
That said, I'm rather pleased with this outcome... the man was a Grade A USDA certified asshat before he started losing his marbles. His incompetence has led to LGBT, domestic violence victims, immigrants, and the list goes on, all getting booted off his site thanks to a broken "real name" policy enforced by an easily manipulated algorithm.... resulting in some people having to submit the same ID documents over and over again month over month. His incompetence led to the rise of "fake news" that spread virally and influenced many political campaigns. It's led to such things as advertisements for housing that can pre-select people based on race, gender, sexual orientation... basically anything that was illegal to do with a newspaper you can do on Facebook. Their "fix" for this problem was to add a dropdown on the form to categorize the advertisement. No human checks it. So it'll only block using those qualifiers if you specifically select the "housing" or "employment" options. Feel free to use miscellany instead.
Frankly, if the man fell into a volcano I would consider it his most significant contribution to society.
