I liked this article quite a bit, as I love to program in Lisp (well, Scheme) and I'm a clinician with a lot of experience treating bipolar disorder. That is, the real bipolar, which isn't what the author is talking about. The kind of behavior referred to in the article is certainly common. I've know many people who show this "crash and burn" pattern. Easily bored, distractible, procrastinators to the end. Black and white, all or none is their theme. Very good or lousy at any given task, usually performance varies randomly, that being a source of consternation for all involved. The unpredictability and inconsistency are vexing and corrosive in nearly all domains of life. They may be subject to moodiness, reacting strongly to criticism, and may blow up disproportionately. Such individuals may become truly depressed but that's not usual. Rather they suffer profound discouragement when things get hard and overwhelming, a state that's almost inevitable, if transient, like thunderstorms propagating flash floods of high drama and rapid dissipation. It's a condition that often responds to treatment, the right kinds of counseling, in some cases carefully applied medication therapies are useful. The college-age students who are flailing around struggling to gain traction often respond the best to proper guidance and approaches. The professor observes correctly the tremendous suffering and waste of talent that occurs. What's important is to see it for what it is and having seen it doing the things that can heal it, in the end giving no cause for pessimism at all.
