"I'll never forget the day I picked up an incoming order form from one of the western jobbers, and found that the keyboard was locked when I tried to punch it into the control console. It completely baffled me at first. Then, while I was tracing out the circuits to see if I could discover what was holding the keyboard lock in, I noticed that the order was already entered on the in-progress list. I was a long time convincing myself that it had really happened, but there was no other explanation.
"The machine had realized that whenever one of those forms came in, I copied the list of goods from it onto the in-progress list through the console keyboard, thus activating the producing mechanisms in the back of the plant. The machine had done it for me this time, then locked the keyboard so I couldn't enter the order twice. I think I held down the kicker button for a full five minutes that day."
"This kicker button," Peter said tentatively, "it's like the pleasure center in an animal's brain, isn't it?"
When Lexington beamed, Peter felt a surge of relief. Talking with this man was like walking a tightrope. A word too much or a word too little might mean the difference between getting the job or losing it.
"Exactly!" whispered Lexington, in an almost conspiratorial tone. "I had altered the circuitry of the machine so that it tried to give me pleasure—because by doing so, its own pleasure circuit would be activated.
"Things went fast from then on. Once I realized that the machine was learning, I put TV monitors all over the place, so the machine could watch everything that was going on. After a short while I had to increase the memory bank, and later I increased it again, but the rewards were worth it. Soon, by watching what I did, and then by doing it for me next time it had to be done, the machine had learned to do almost everything, and I had time to sit back and count my winnings."
At this point the door opened, and a small self-propelled cart wheeled silently into the room. Stopping in front of Peter, it waited until he had taken a small plate laden with two or three cakes off its surface. Then the soft, evenly modulated voice he had heard before asked, "How do you like your coffee? Cream, sugar, both or black?"
Peter looked for the speaker in the side of the cart, saw nothing, and replied, feeling slightly silly as he did so, "Black, please."
A square hole appeared in the top of the cart, like the elevator hole in an aircraft carrier's deck. When the section of the cart's surface rose again, a fine china cup containing steaming black coffee rested on it. Peter took it and sipped it, as he supposed he was expected to do, while the cart proceeded over to Lexington's desk. Once there, it stopped again, and another cup of coffee rose to its surface.
