"What else than a natural and mighty palimpsest is the human brain? Everlasting layers of ideas, images, feelings, have fallen upon your brain softly as light. Each succession has seemed to bury all that went before. And yet, in reality, not one has been extinguished." - Thomas De Quincey, 1845 There is a scene in The Twilight Zone that deserves to be far more famous than it is. In " The Brain Center at Whipple's," a CEO named Wallace Whipple has decided to replace his factory workers with machines.
