Slowly, North Korea is entering the online world. Thanks to technology, North Korean doctors can talk to patients through online video conferencing. Speeches given at Kim Il Sung University in Pyongyang, the capital, can be seen at faraway factories. North Koreans send text messages to each other on their smartphones. People are even buying products and doing their banking online. Yet North Korea is still among the least internet-friendly countries on Earth. For most citizens, having a connection to the World Wide Web is unimaginable. Hardly anyone has a personal computer or an email address that is not shared. But for Kim Jong Un, the country’s first leader to grow up in the internet age, the idea of a more wired North Korea is also appealing. It comes with the promise of new forms of social and political control, and the possibility of cyber-attacks on the West.
