Barack Obama:

We live in a time of such confusion and rancor, with a culture that puts a premium on things that don’t last: money, fame, status, likes. We chase the approval of strangers on our phones. We build all manner of walls and fences around ourselves, and then we wonder why we feel so alone. We don’t trust each other as much because we don’t take the time to know each other. And in that space between us, politicians and algorithms teach us to caricature each other and troll each other and fear each other.
