I have not. Why do you ask? You have certainly piqued my interest.

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.
