Plenty of people out there, more than we're willing to admit, are callous, unfeeling, unempathetic, and uncaring. They may not rise to the level of outright sociopathy or psychopathy, but they generally do not regard emotions highly, negative or positive. This archetype is overrepresented in academia and science, so make of that what you will.

FWIW in tech I think this is often poor emotional awareness and lacking emotional vocabulary than callousness and a lack of emotions in themselves. Kind of state you end up in if you spend too much time with computers and books and not enough learning the nuances of social life as a kid.

Though with Harlow I don't know. Gives me a vibe he could have been a season of Mindhunter if he'd made a few different life choices.
