After Aliens arrive, the story takes place in two time streams: 2017 and 2037. In twenty years, and by 2037, the world has been divided into a “Smart Earth” where artificial intelligence has created a utopian environment in which no diseases or crimes exist, and an “Ordinary Earth” where people still suffer from rampant plague and lawlessness.
