As Hegel pointed out, the tragedy of the masters is that they cannot escape from dependence on their slaves. Rich white Californians need their darker-skinned fellow humans to work in their factories, pick their crops, look after their children and tend their gardens. Unable to surrender wealth and power, the white people of California can instead find spiritual solace in their worship of technology. If human slaves are ultimately unreliable, then mechanical ones will have to be invented. The search for the holy grail of Artificial Intelligence reveals this desire for the Golem - a strong and loyal slave whose skin is the colour of the earth and whose innards are made of sand. The techno-utopians imagine that it is possible to obtain slave-like labour from inanimate machines. Yet, although technology can store or amplify labour, it can never remove the necessity for humans to invent, build and maintain the machines in the first place. Slave labour cannot be obtained without somebody being enslaved. At his estate at Monticello, Jefferson invented many ingenious gadgets - including a 'dumb waiter' to mediate contact with his slaves. In the late twentieth century, it is not surprising that this liberal slave-owner is the hero of those who proclaim freedom while denying their brown-skinned fellow citizens those democratic rights said to be inalienable.
