I must be unenlightened because this job would make me quite misanthropic. Even sitting in a doctors waiting room gives me that feeling.
It seems to me that a significant point of the article is that this is a choice you're continuously making, not an immutable fact about you.
I can relate but I've found it's really less about the people and more about my current state and how (in)frequent is my exposure to them.
I started renting a desk in a co-working space starting this year and there's a new guy here who conducts his meetings in the room instead of going to the conference booth and uses a pretty loud mechanical keyboard.
Half a year ago, when I was still working from home and not going out much, I would lose my shit. It's not that it's not annoying, I'm just a little bit desensitized to it.
