Years ago I worked with someone who I instantly thought of when reading this article. He would put comments in code making fun of other people’s code, refused to participate in any company training or onboarding, he put nasty voicemail greetings on his voicemail, was just an overall disagreeable person and had disdain for everyone and everything around him.

I saw his obituary years later - “passed away unexpectedly at home” at the age of 53. I can’t imagine how stressful and sad it must be to look at the world so negatively.
