large for a manufacturing plant—it took a scant minute to exhaust its straightened his jacket and tie, and walked in as an engineer applying 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 get a job with someone else?" Peter stared his disbelief. Automated plants were nothing new, but disorganized machinery, Peter noticed that the factory lights high overhead followed their progress, turning themselves on in advance machines, apparently self-powered, rolled noiselessly up to the door in 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 tugged it into a more attractive position. It took only a split second, trace of anger not yet gone from his voice. "When an order is received, it's translated into the catalogue numbers used internally within the plant, and machines like the ones you just saw withdraw the necessary Peter followed numbly as Lexington led him through a maze of machines, everywhere, scuttling from machine to machine, apparently with an onrushing wheels, saw himself clambering out of the path of the that was laboring beside him at the moment. Nervously, he looked for an exit, but his apprehension was unnecessary. The machines seemed to know there's a very similar rig set up in conjunction with an automatic bookkeeper to keep track of the pennies and to bill the customers." "Then all you do is read the incoming mail and maintain the machinery?" Apparently the walk through the factory had tired him considerably, determined not to make the same mistake again. But I did. I got too absorbed in those parts of the course that had to do with electrical 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 business I got, and the more I had to expand." 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, and from studies of nerve tissue in particular, plus my electrical knowledge, I had a few ideas on how to do it. It took me three years, but I began to see that I could develop circuitry that could remember, compare, detect similarities, and so on. Not the way they do it today, of course. To do what I wanted to do with these big clumsy magnetic work for me. "By creating the proper compounds, with their molecules arranged in predetermined matrixes, I found I could duplicate electrical circuitry in units so tiny that my biggest problem was getting into and out of the logic units with conventional wiring. I finally beat that the same way they solved the problem of translating a picture on a screen into electrical signals, developed equipment to scan the units cyclically, and once I'd done that, the battle was over. "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 the back of this place. I figured that the best thing for me to do control section. One was simply a huge memory bank. The other was a comparator circuit. A complicated one, but a comparator circuit nevertheless. Here I was working on instinct more than anything. I figured that if I interconnected these circuits in such a way that they could sense everything that went on in the plant, and compare one action with another, by and by the unit would be able to see patterns. "Then, through the existing command output, I figured these new units would be able to control the plant, continuing the various patterns of activity that I'd already established." Here Lexington frowned. "It didn't work worth a damn! It just sat there and did nothing. I couldn't understand it for the longest time, and then I realized what the trouble was. I put a kicker circuit into it, a sort of voltage-bias network. I reset the equipment so that while it was still under instructions to receive orders and produce goods, its prime purpose was to activate the kicker. The kicker, however, could only be activated by me, manually. Lastly, I set up one of the early TV pickups over the mail slitter and allowed every letter I received, every order, to be fed into the memory banks. That did it." "I—I don't understand," stammered Peter. "Simple! Whenever I was pleased that things were going smoothly, I pressed the kicker button. The machine had one purpose, so far as its logic circuits were concerned. Its object was to get me to press that button. Every day I'd press it at the same time, unless things weren't going well. If there had been trouble in the shop, I'd press it late, or maybe not at all. If all the orders were out on schedule, or ahead of time, I'd press it ahead of time, or maybe twice in the same day. Pretty soon the machine got the idea. "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 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 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 A square hole appeared in the top of the cart, like the elevator hole machine couldn't fix for itself." Handling the cup as if it were going to shatter at any moment, he took a gulp. "I began to see that the machine could understand the written word, and I tried hooking a teletype directly into the logic circuits. It was like uncorking a seltzer bottle. The machine had a funny vocabulary—all of it gleaned from letters it had seen coming in, and replies it had seen leaving. But it was intelligible. It even displayed some traces of the personality the machine was acquiring. "It had chosen a name for itself, for instance—'Lex.' That shook me. You might think Lex Industries was named through an abbreviation of was named after the nickname she always used. I objected, of course, but how can you object on a point like that to a machine? Bear in mind that I had to be careful to behave reasonably at all times, because the machine was still learning from me, and I was afraid that any tantrums I threw might be imitated." the machine had taken the damnedest risks you ever saw on bids and contracts for supply. It was quoting impossible delivery times on some orders, and charging pirate's prices on others, all without any a long, hard push. The button, much to my amazement, had been removed, ever sent. 'LEX—WHAT THE HELL?' I typed. "The answer came back in the jargon it had learned from letters it had
