I would submit that this could be based on a stereotype that “coder = antisocial.”

Why are we assuming that people who write code don’t have soft skills?

The youngest generation who joined the profession are probably in it for the the salary versus the older generations who came from computer clubs and dungeons and dragons groups of the 1970s/1980s along with a culture where having a niche interest was socially ostracizing and uncool.

I wonder if the youngest generation entering the profession is much more of a cross section of regular people?
