TikTok can feel, to an American audience, a bit like a greatest hits compilation, featuring only the most engaging elements and experiences of its predecessors. This is true, to a point. But TikTok — known as Douyin in China, where its parent company is based — must also be understood as one of the most popular of many short-video-sharing apps in that country. This is a landscape that evolved both alongside and at arm’s length from the American tech industry — Instagram, for example, is banned in China.


Under the hood, TikTok is a fundamentally different app than American users have used before. It may look and feel like its friend-feed-centric peers, and you can follow and be followed; of course there are hugely popular “stars,” many cultivated by the company itself. There’s messaging. Users can and do use it like any other social app. But the various aesthetic and functional similarities to Vine or Snapchat or Instagram belie a core difference: TikTok is more machine than man. In this way, it’s from the future — or at least a future. And it has some messages for us.
