“Nude selfies till I die.” Kim Kardashian’s 2016 Webby Award acceptance speech for “excellence on the internet” was totally #goals. It also speaks to the reconfiguration of the public and private in our smartphone society. Kim and her selfie-obsessed sisters post sultry snaps of themselves online — taken in their bathrooms, bedrooms, and cars — and millions of people devour them.

The formula is robust. Forbes named Kylie Jenner the “world’s youngest self-made billionaire” at twenty-one.

Of course, relatively few of us are cultivating our social media biopics for the Benjamins. Yet if we’re honest, many of us rival the Kardashians in how “extremely online” our lives have become. Three billion people a month spend an average of 135 minutes a day on social media, and 70 percent of our social media time is spent on our phones (total screen time stretches considerably longer). Social media experts say that “to decouple social media from mobile use is impossible.”
