In our recent series on artificial intelligence, I kept returning to a thought: This technology might be able to churn out content faster than we can, but we still need a human mind to sift through the dross and figure out what’s good. In other words, A.I. is going to turn more of us into editors.

But editing is a peculiar skill. It’s hard to test for, or teach, or even describe. But it’s the crucial step in the creative process that takes work that’s decent and can turn it into something great.

Adam Moss is widely known as one of the great magazine editors of his generation: He remade The New York Times Magazine in the late 1990s and early 2000s, and during his 15 years as editor in chief of New York magazine, shaped that outlet into one of the greatest print and digital publications we have. And he’s now out with a new book, “The Work of Art: How Something Comes From Nothing.” It’s a curation of 43 conversations with artists about the marginalia, doodles, drafts and revisions that lead to great art. It’s a celebration of the hard, human work that goes into the creative act. It’s a book, really, about editing.

In this conversation, we discuss what musicians, writers, visual artists, sandcastle-builders and others have in common as they create; how editing is an underappreciated and often misunderstood step in the creative process; how creativity morphs in different stages of our lives; and trusting your own “sensibility.”
