All Watched Over by Machines of Loving Grace

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. They believed that the new computer networks would allow the creation of a society where everyone could follow their own desires, yet there would not be anarchy. They were joined by Alan Greenspan who had also been a disciple of Ayn Rand. He became convinced that the computers were creating a new kind of stable capitalism - "Like a New Planet", he said. But the dream of stability in both worlds would be torn apart by the two dynamic human forces - love and power.

This is the story of how our modern scientific idea of nature, the self-regulating ecosystem, is actually a machine fantasy. It has little to do with the real complexity of nature. It is based on cybernetic ideas that were projected on to nature in the 1950s by ambitious scientists. A static machine theory of order that sees humans, and everything else on the planet, as components - cogs - in a system. But in an age disillusioned with politics, the self-regulating ecosystem has become the model for utopian ideas of human 'self-organizing networks' - dreams of new ways of organising societies without leaders, as in the Facebook and Twitter revolutions, and in global visions of connectivity like the Gaia theory. This powerful idea emerged out of the hippie communes in America in the 1960s, and from counterculture computer scientists who believed that global webs of computers could liberate the world. But, at the very moment this was happening, the science of ecology discovered that the theory of the self-regulating ecosystem wasn't true. Instead they found that nature was really dynamic and constantly changing in unpredictable ways. But the dream of the self-organizing network had by now captured our imaginations - because it offered an alternative to the dangerous and discredited ideas of politics.

This episode looks at why we humans find this machine vision so beguiling. The film argues it is because all political dreams of changing the world for the better seem to have failed - so we have retreated into machine-fantasies that say we have no control over our actions because they excuse our failure. At the heart of the film is one of the most famous scientists in the world - Bill Hamilton. He argued that human behaviour is really guided by codes buried deep within us. It was later popularised by Richard Dawkins as 'the selfish gene'. It said that individual human beings are really just machines whose only job is to make sure the codes are passed on for eternity. The film begins in 2000 in the jungles of the Congo and Rwanda. Hamilton is there to help prove his dark theories. But all around him the Congo is being torn apart by 'Africa's First World War'. The film then interweaves the two stories - the strange roots of Hamilton's theories, and the history of the West's tortured relationship with the Congo over the past 100 years.
