Even his other examples don't make sense. I don't know if he's actually talked to musicians or writers, but I would be willing to bet that many of them actually don't work in pairs. Musicians may play as a group, but composition, as far as I can tell, is a fairly solitary activity. In the same manner, writing is fairly solitary, even though editing and review are social. To translate this into programming, I'd say that programming should be solitary while code reviews should be done in pairs. EDIT: Even the rally driving example doesn't make sense. In rally driving, there is a driver and there is a navigator. The roles are different and very clearly defined from one another. This is nothing like pair-programming, where the distinction in roles between the person at the keyboard and the person watching is much looser and the two people are expected to take turns at the helm.
