So pg is just factually wrong.
Pg seems to have some kind of fantasy that Jessica is a gifted psychologist. The truth is that she probably is when compared to other autism-spectrum programmers, but not when compared to professional cousellors or other people whose job it is to understand and empathize.
What Jessica considers niceness--"niceness for the purpose of making money"--is not going to be the same as what most people consider niceness.
The programming world scores high on the autism spectrum and on the psychopath spectrum. Compared to the rest of the world, programmers seem like very mean, cold, ruthless people.
