A series of films written and directed by Adam Curtis about how humans have been colonised by the machines they have built. Although we don't realise it, the way we see everything in the world today is through the eyes of the computers. The film tells the story of two perfect worlds. One is the small group of disciples around the novelist Ayn Rand in the 1950s. They saw themselves as a prototype for a future society where everyone could follow their own selfish desires. The other is the global utopia that digital entrepreneurs in Silicon Valley set out to create in the 1990s. Many of them were also disciples of Ayn Rand.
