“The same technologies that were meant to level the political playing field have brought troll farms and Russian bots to corrupt our elections. The same platforms of self-expression that we thought would let us empathize with one another and build a more harmonious society have been co-opted by figures such as Milo Yiannopoulos and, for that matter, Donald Trump, to turn white supremacy into a topic of dinner-­table conversation. And the same networked methods of organizing that so many thought would bring down malevolent states have not only failed to do so—think of the Arab Spring—but have instead empowered autocrats to more closely monitor protest and dissent.” Harper’s: The rise of the internet and a new age of authoritarianism.
