“Ready when you are, sir.”

“Good. Let’s get started. I don’t want this to take all night.” J. J. Beckworth turned his back when he spoke — there was no need for anyone to know that he kept the security key in a special compartment in his belt buckle — men strode across the office to the steel panel set in the wall. It opened when he turned the key and a red light began blinking inside. He had five seconds to punch in his code. Only when the light had turned green did he wave Toth over. J.J. replaced the key in its hiding place while the security chief entered his own code, his fingers moving unseen inside the electronic control box. As soon as he had done this, and closed the panel again, the telephone rang.

J.J. verbally confirmed the arrangements with Security Control Central. He hung up and started for the door.

“The computer is processing the order,” J.J. said. “In ten minutes it will make entry codes available at the outer laboratory terminal. We will then have a one-minute window of access before the entire operation is automatically canceled. Let’s go.”

If the security arrangements were invisible during the day this certainly was not true at night. In the short walk from the office block to the laboratory building they encountered two guards on patrol — both with vicious-looking dogs on strained leashes. The area was brilliantly lit, while TV cameras turned and followed them as they walked through the grounds. Another guard, his Uzi submachine gun ready, was waiting outside the lab doors. Although the guard knew them all, including his own boss, he had to see their personal IDs before he unlocked the security box. J.J. waited patiently until the light inside turned green. He entered the correct code, then pressed his thumb to the pressure plate. The computer checked his thumbprint as well. Toth repeated this procedure, then in response to the computer’s query, punched in the number of visitors.

“Computer needs your thumbprint too, Dr. McCrory.”

Only after this had been done did the motors hum in the frame and the door clicked open.

“I’ll take you as far as the laboratory,” Toth said, “but I’m not cleared for entry at this time. Call me on the red phone when you are ready to leave.”

The laboratory was brilliantly lit. Visible through the armor-glass door was a thin, nervous man in his early twenties. He ran his fingers anxiously through his unruly red hair as he waited.

“He looks a little young for this level of responsibility,” J. J. Beckworth said.

“He is young — but you must realize that he finished college before he was sixteen years old,” Bill McCrory said. “And had his doctorate by the time he was nineteen. If you have never seen a genius before you are looking at one now. Our headhunters followed his career very closely, but he was a loner with no corporate interest, turned down all of our offers.”

“Then how come he is working for us now?”

“He overstretched himself. This kind of research is both expensive and time-consuming. When his personal assets began to run out we approached him with a contract that would benefit both parties. At first he refused — in the end he had no choice.”

Both visitors had to identify themselves at another security station before the last door opened. Toth stepped aside as they went in; the computer counted the visitors carefully. They entered and heard the door close and lock behind them. J. J. Beckworth took the lead, knowing that the easier he made this meeting, the faster he would get results. He extended his hand and shook Brian’s firmly.

“This is a great pleasure, Brian. I just wish we could have met sooner. I have heard nothing but good news about the work you have been doing. You have my congratulations — and my thanks for taking the time to show me what you have done.”

Brian’s white Irish skin turned red at his unexpected praise. He was not used to it. Nor was he versed enough in the world of business to realize that the Chairman was deliberately turning on the charm. Deliberate or not, it had the desired result. He was more at ease now, eager to answer and explain. J.J. nodded and smiled.

“I have been told that you have had an important breakthrough. Is that true?”

“Absolutely! You could say that this is it — the end of ten years’ work. Or rather the beginning of the end. There will be plenty of development to come.”

“I was given to understand that it has something to do with artificial intelligence.”

“Yes, indeed. I think that we have some real AI, at last.”

“Hold your horses, young man. I thought that AI had been around for decades?”

“Certainly. There have been some pretty smart programs written and used that have been called AI. But what I have here is something far more advanced — with abilities that promise to rival those of the human mind.” He hesitated. “I’m sorry, sir, I don’t mean to lecture. But how acquainted are you with the work in this field?”

“To be perfectly frank, I know nothing at all. And the name is J.J., if you don’t mind.”

“Yes, sir — J.J. Then if you will come with me I will bring you up to date a little bit.”

He led the way to an impressive array of apparatus that filled an entire laboratory bench. “This is not my work, it’s a project that Dr. Goldblum has under way. But it makes a perfect introduction to AI. The hardware isn’t much, it’s an old Macintosh SE/60 with a Motorola 68050 CPU and a data-base coprocessor that increases its execution speed by a factor of 100. The software itself is based on an updated version of a classic Self-Learning Expert System for renal analysis.”

“Just hold it there, son! I don’t know what a renal is. I know a little about Expert Systems, but what was it you said — a Self-Learning Expert System? You are going to have to go back and start at square A if you don’t want to lose me.”

Brian had to smile at this. “Sorry. You’re right, I better go back to the beginning. Renal refers to kidney functions. And Expert Systems, as you know, are knowledge-based programs for computers. What we call computer hardware is the machinery that just sits there. Turn off the electricity switch and all you have are a lot of expensive paperweights. Turn it on and the computer has just enough built-in programming to test itself to see if it is working all right, then it prepares to load in its instructions. These computer instructions are called software. These are the programs that you put in to tell the hardware what to do and how to do it. If you load in a word processing program you can then use the computer to write a book. Or if you load a bookkeeping program the same computer will do high-speed accountancy.”

J.J. nodded. “I’m with you so far.”

“The old, first-generation programs for Expert Systems could each do only one sort of thing, and one thing only — such as to play chess, or diagnose kidney disease, or design a computer circuit. But each of those programs would do the same thing over and over again, even if the results of doing so were unsatisfactory. Expert Programs were the first step along the road to AI, artificial intelligence, because they do think — in a very simple and stereotyped manner. The self-learning programs were the next step. And I think my new learning-learning type of program will be the next big step, because it can do so much more without breaking down and getting confused.”

“Give me an example.”

“Do you have a languaphone and a voxfax in your office?”

“Of course.”

“Then there are two perfect examples of what I am talking about. Do you take calls from many foreign countries?”

“Yes, a good number. I talked with Japan quite recently.”

“Did the person you were talking to hesitate at any time?”

“I think so, yes. His face sort of froze for an instant.”

“That was because the languaphone was working in real time. Sometimes there is no way to instantly translate a word’s meaning, because you can’t tell what the word means until you have seen the next word — like the words ‘to,’ ‘too,’ and ‘two.’ It’s the same with an adjective like ‘bright,’ which might mean shining or might mean intelligent. Sometimes you may have to wait for the end of a sentence — or even the next sentence. So the languaphone, which animates the face, may have to wait for a complete expression before it can translate the Japanese speaker’s words into English — and animate the image to synchronize lip movements to the English words. The translator program works incredibly fast, but still it sometimes must freeze the image while it analyzes the sounds and the word order in your incoming call. Then it has to translate, again, into English. Only then can the voxfax start to transcribe and print out the translated version of the conversation. An ordinary fax machine just makes a print of whatever is fed into a fax machine at the other end of the connection. It takes the electronic signals that it receives from the other fax and reconstructs a copy of the original. But your voxfax is a different kind of bird. It is not intelligent — but it uses an analytical program to listen to the translated or English words of your incoming telephone calls. It analyzes them, then compares them with words in its memory and discovers what words they make up. Then it prints out the words.”
