Very well put. I'd add the psychological concept of dissociation which seems to be central to the hackernews version of stoicism. Instead of connecting to your emotions it encourages pushing them down. That's just going to postpone the moment when you have to deal with them. Either because of psychosomatic illness, depression, burn out or mental breakdown. Attempting to influence, change, control feelings/emotions by rational concepts and thinking is doomed to fail. Emotions are on a lower level than verbal and logical mental processes.

As someone who has run multiple “empire tier” tech platforms, I’ve learned personally why you tend to develop this mindset.

This brand of stoicism you refer to is high order “cope” with your emotional self telling you it is wrong.
