New Guinea remained on my radar: a horizon of maximum difference, a test bed for linguistics and for linguists. Elsewhere, linguistic differences usually stem from geographic isolation. But in much of New Guinea the diversity is actually deepest in places where travel is easiest. Instead of using religion, clothing, or food, Papua New Guineas have distinguished themselves above all through language. Call it tribalism or, as linguists do, the “constructive fostering of variegation” through “intentional language change.”

The negative consensus surrounding the show has now reached sufficient mass that one can now put it on the couch. At its psychic root, all the criticism appears to converge at one point: Koolhaas himself, and the methodology he represents.

Notice how the register of the prose, with its figures and rates, evokes the rhetoric of nonfiction. The use of general, declarative sentences about Mexico, in particular, makes me think of what my journalism professors used to call the nut-graf—the paragraph in the article where the journalist briefly pauses her account of the news to establish, in the most efficient way possible, the context for the events on which she is reporting. The result is that Cummins’s book often slips into didacticism.

Around 2014, I began to talk to friends about Joni and was disappointed—surprised—by how little they knew. These were people who listened to music. I had a conversation about her with a highly accomplished ex-student in New York, a writer who had musical training, who thought I was talking about Janis Joplin. This was related to a problem: the plethora of Js among women musicians of the time, which led to their conflation into a genre. Janis Joplin, Judy Collins, Joan Baez, and Joni Mitchell: the last three especially were seen as interchangeable. Even if I put down my ex-student’s confusion to uncharacteristic generational ignorance, I found that, on mentioning Joni to a contemporary I had to work hard to distinguish her from Joan Baez. My friend had dismissed—not in the sense of “rejected,” but “taxonomized”—Joni as being part of a miscellany of singers with long, straight hair, high, clear voices, and a sincerity that shone brightly in the mass protests of the late ’60s. Visually, in her early acoustic performances with guitar, and even in her singing, she appropriated the folk singer’s persona to the point of parody, while the songwriting was absolutely unexpected. To prove this to my friend, I played her “Rainy Night House” and “Chinese Café / Unchained Melody.” It became clear in twenty seconds that Mitchell was not Joan Baez.
