The pain comes from brain cells that are committing suicide because they're so frustrated, all they can think to do is end it all.
It's like lurching at the end of a rope when it breaks while you're playing tug of war, except it turns out it wasn't a rope at all, it was a bar fight.
Using a computer always puts you at the edge of a haze, managing more complexity than your poor brain can handle. An overload caused by a misdirection == burning brain cells.
Nothing new. Software has been doing it since Day One, I'm sure. I mention it because it happens all the time on Facebook. You're reading a message from a friend and then your brain slams shut because it realizes it's actually an ad!
It's good I suppose for the advertiser and Facebook, but it's not good for my poor brain. Or yours either. And maybe ultimately it'll be bad for Zuck when we all get to the afterlife and get to tell him what we think about it.
Thanks for listening.
