A decade is an arbitrary measurement. They seem confined, these neat little symmetrical 10-year runs, but it’s only in hindsight that we define them, that their signifiers and trends and shorthand become codified. In reality, there are bleeds, the timbre and events of one chunk of time sliding over the border into another. If you’re seeking to characterize any period while you’re still living it, chances are that’s what you’ll see: the murkiness, the things that hang around or are just bubbling up, not yet having the distance to look back and tie a bow around history. Still, when that history is written for the 2010s, it feels as if it might still be looked at as a messy, transitional time — socially, politically, culturally.
