One of these days I’m going to get back into shape. Then I’m going to fly to Nepal. Then I’m going to hire a Sherpa to guide me on an arduous journey up into the highest reaches of the Himalayas. Along the way he’ll teach me his language, as well as the customs of his people. By the time we arrive at the summit, we will have saved each others’ lives several times, binding our fates together for all eternity. Sitting atop the apex of the world (beneath a sign that says, “No Flash Photography Allowed”) will be a shriveled old man with a long beard who will explain to me the sorcery and wonder behind the algorithm that determines what’s going to show up as a “suggested post” on my Facebook news feed.
