Chronic traumatic encephalopathy, or CTE, is a brain disease achieved by getting hit on the head a lot, and it's usually found in football players and boxers.  Some of the symptoms include impulsive behavior and aggression. 

It's a real thing, and I don't mean to make light of it.  But there's a pattern of behavior I've noticed in certain public figures in recent years that suggests something similar is happening to otherwise healthy people.  There was the football player Antonio Brown who walked off the field (i.e. quit) mid-game in a pretty dramatic fashion (though that might've actually been CTE).  There was the Dilbert creator Scott Adams who used to post benign little things on his blog and Twitter, but who has since devolved into a racist and an extreme fear-mongerer.  There's also Jordan Peterson, who achieved notoriety with a fairly benign self-help book, but who has since become an aggressively annoying Twitter personality.  Add to this list JK Rowling, who earned a billion dollars as a young adult author, but whose entire public life now consists of degrading transgender people for some reason.  And then there's Elon Musk, who used to be an awkward nerd but has since become a Nazi.  Also, Donald Trump. 

You could claim these people are just doing things for attention.  Or maybe that's how these people have always been, and social media has simply allowed them to be more visible about it.  But I think it's something else.  It might be that, similar to CTE, social media has altered peoples' brain to make them act more impulsive and aggressive.  Or it might be drugs (Elon) or supplements (Adams -- men that old shouldn't have abs).  I don't know what it is, but I don't like it, and I think social media should be abolished and people should have to obtain a license to use the internet. #psychology
