This person, of whom I never read before reading the article, is kind of a hero in my eyes. Fully committed to their work and writing amazing software it seems. Good. More people should do so, if it makes them happy. Not everyone needs to found a family and have a 9 to 5 job. I am a big fan of society allowing for some special cases, where people can unfold their potential, instead of forcing them into some (for them) boring or unproductive jobs.
