In Silicon Valley, a tech company valued at $1 billion is called a unicorn. Silicon Valley has spawned herds of unicorns, such as Uber and Airbnb. But Africa hasn’t, despite some fast-growing economies – think Ethiopia and Nigeria – and the world’s fastest-growing population.

The Arctic tundra is slowly reclaiming a city in Russia’s far north. The collapse of the Soviet Union and closure of local mines prompted the exodus of two-thirds of Vorkuta’s population over the past three decades. In one suburb, the shells of former theaters and ice-bound playgrounds hint at happier times.
