Nothing in the world could be happier and mere serene than a man who loves his work—but what happens when it loves him back? and eviction if he came away from this interview still unemployed. Clay, at the Association of Professional Engineers, who had set up the large for a manufacturing plant—it took a scant minute to exhaust its for him. interview—and it's not your fault—this whole setup is geared to His eyes eventually had to move to Lexington, and they were daunted "What can you do?" asked Lexington abruptly. "Good," said Lexington. "Only a fool would try to answer that. Do you "I'm applying for a job as engineer." "I know. Are you interested in the basics of how we live?" "Less than you think," Lexington said. "It's the preconceived notions "Stockpiled you," Lexington said. "Not very much, but we were getting the training instead of wages." "That guff about receiving training instead of wages!" said Lexington. their products being made, maybe you didn't. But you're a lot weaker in calculus." "Just as I said—they stockpiled you, instead of using you as an engineer. They hired you at a cut wage and taught you things that would be useful only in their own company, while in the meantime you were getting weaker in the subjects you'd paid to learn. Or are you one of "Impossible, you mean. You wouldn't know a single thing except their any wage you'd stand for, and they'd have an indentured worker with a degree—but not the price tag. You see that now?" "That's right." "Well," said Lexington unexpectedly, "there "And I've just proved you're less of an engineer than when you left "Well, am I?" Lexington demanded. Peter had the startling feeling that Lexington was rooting for him! tiredness. "Good again. The man I want doesn't exist. He has to or cockiness wouldn't get you anywhere here, and you were right. "Very good," said Lexington. "Most people only notice the automatic they all had their limitations. Either they dealt with exactly similar products or things that could be handled on a flow basis, like oil or water-soluble chemicals. Even these had no more to do than process the "Come on," said Lexington, getting massively to his feet. "I'll show the manufacturing area. As they moved along, between rows of seemingly Lexington paused here. "This is the bay used by the trucks arriving with raw materials," he said. "They back up to this door, and a set of automatic jacks outside lines up the trailer body with the door exactly. Then the door opens and the truck is unloaded by these Lexington went over to one of them and patted it lovingly. "Really, these machines are only an extension of one large machine. The whole plant, as a matter of fact, is controlled from one point and is really a single unit. These materials handlers, or manipulators, were about the toughest things in the place to design. But they're tremendously useful. You'll see a lot of them around." Lexington was about to leave the side of the machine when abruptly one and before Lexington could react, all three machines were moving away frustrated embarrassment that crossed Lexington's face, only to be it's translated into the catalogue numbers used internally within the plant, and machines like the ones you just saw withdraw the necessary materials from stock, make the component parts, assemble them, and package the finished goods for shipment. Simultaneously, an order is sent to the billing section to bill the customer, and an order is purchasing section is instructed to order more raw materials. I'll take you through the manufacturing and assembly sections right now, but each one seemingly intent on cutting, bending, welding, grinding or carrying some bit of metal, or just standing idle, waiting for everywhere, scuttling from machine to machine, apparently with an exact knowledge of what they were doing and the most efficient way of He wondered what would happen if one of them tried to use the same Back in the office section of the building, Lexington indicated a small there's a very similar rig set up in conjunction with an automatic when they walked back into Lexington's office and sat down. Lexington Finally Lexington spoke. "I know it's hard to believe, but there it is." "Damn fools!" exclaimed Lexington, getting part of his breath back. idiotic notions about specialization." Lexington mopped his forehead with a large white handkerchief. Apparently the walk through the factory had tired him considerably, although it hadn't been strenuous. arrival. "You know what we make, of course." Lexington sank deeper in his chair and stared at the ceiling as he suppose it would have grown just like any other business, except for a strike that came along and put me right back where I started. My girl. "For the next few years, I concentrated on getting rid of as many employees as I could, by replacing them with automatic machines. I'd design the control circuits myself, in many cases wire the things up myself, always concentrating on replacing men with machines. But it wasn't very successful. I found that the more automatic I made my plant, the lower my costs went. The lower my costs went, the more Lexington scowled. "I got sick of it. I decided to try developing one multi-purpose control circuit that would control everything, from ordering the raw materials to shipping the finished goods. As I told you, I had taken quite an interest in biology when I was in school, knowledge, I had a few ideas on how to do it. It took me three years, compare, detect similarities, and so on. Not the way they do it today, work for me. "By creating the proper compounds, with their molecules arranged in the logic units with conventional wiring. I finally beat that the same "I built this building and incorporated it as a separate company, to compete with my first outfit. In the beginning, I had it rigged up to do only the manual work that you saw being done a few minutes ago in Lexington smiled. "Well, automated as it was, it couldn't compete with this plant. It gave me great pleasure, three years after this one the old firm's equipment for next to nothing and I wound up with all my they could sense everything that went on in the plant, and compare one would be able to control the plant, continuing the various patterns of Here Lexington frowned. "It didn't work worth a damn! It just sat there Pretty soon the machine got the idea. When Lexington beamed, Peter felt a surge of relief. Talking with this "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 "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 Lexington took the coffee from the top of the car, obviously angry "Not only expensive, but stupid and impractical!" exploded Lexington. Lexington stared at his cup without touching it for a long while. Then machine couldn't fix for itself." Handling the cup as if it were going to shatter at any moment, he took It was like uncorking a seltzer bottle. The machine had a funny the name Lexington, but it wasn't. My wife's name was Alexis, and it but how can you object on a point like that to a machine? Bear in mind machine was still learning from me, and I was afraid that any tantrums the machine had taken the damnedest risks you ever saw on bids and stiff competition, and cutting the production time was the only way we and to make it still better, I'd find that for months I had virtually "It was, in a way. I remember one day I was especially pleased with seen, and I remember it as if it just happened. 'MR. A LEXINGTON, LEX PLEASED WITH MY SERVICE WITHOUT THE USE OF THE EQUIPMENT PREVIOUSLY
