In the beginning there was feedback: the machines speaking on their own, answering their supposed masters with shrieks of misalliance. Gradually the humans learned to control the feedback, or thought they did, and the next step was the introduction of more highly refined forms of distortion and artificial sound, in the form of the synthesizer, which the human beings sought also to control. In the music of Kraftwerk, and bands like them present and to come, we see at last the fitting culmination of this revolution, as the machines not merely overpower and play the human beings but absorb them, until the scientist and his technology, having developed a higher consciousness of its own, are one and the same.
