Update

This is an update to this post. It seems even though my observations were correct, I drew the wrong conclusion.

Though, computer programmer or mathematician can be a desired date, I was actually referring to persons who are passionate about what they do. From my experience, I found most people with the mentioned background are passionate about what they do and that's what attracted me at the first place. So it was never about what they do but more about their attitude to follow their passion.
