This level of optimization away from other humans in my experience tends to come from specific forms of introverted high intelligence (interaction with others is a net loss) but also specialization functionally/professionally away from interaction with humans (typically toward machines, or at least into more constrained work environments).
I haven't yet found something I feel passionately about. I recently finished refactoring a pid-free analytics application but now find myself without motivation. I love solving problems but dislike the rest.
I'll look into the niches you mentioned. Thanks for the reply and your time.
