Norbert Weiner, November, 1947:

“The automatic factory and the assembly line without human agents… makes the metaphorical dominance of the machines… a most immediate and non-metaphorical problem. It gives the human race a new and most effective collection of mechanical slaves to perform its labor. Such mechanical labor has most of the economic properties of slave labor.... However, any labor that accepts the conditions of competition with slave labor accepts the conditions of slave labor, and is essentially slave labor.”
