Caliban

even if this robot did not have hyperwave, how could he not know what it was at first, and yet then be able to look it up? High-level robots sometimes had internal look-up sources, but they were meant for referral to esoteric knowledge needed for a specific job. Certainly such look-up datastores were not meant to serve as a dictionary of common terms. It would be a waste of effort, when such things could have and should have been downloaded to the robot’s brain during manufacture.

What sort of strange robot was this? “Very well,” Horatio said. “We shall talk out loud. What is it that you require?”

“You are supervisor Horatio?”

“Yes. What are you called?”

“Caliban. I am glad to find you, friend Horatio. I need your advice. I tried to seek some sort of help from the other robots, the blue ones working over there, but none of them seemed able to offer me guidance. They advised me to come and talk with you.”

Horatio was more puzzled than ever. The Shakespearean name “Caliban” told him something. Fredda Leving herself had built this robot, as she had built Horatio. But the name “Horatio” should have meant something to this Caliban, and yet it seemed that it did not. Stranger still, this advanced, sophisticated-looking robot had gone to the lowest of laborers seeking advice. The DAA-BOR series robots, such as the blue workers Caliban had gestured at, were capable of only the most limited sort of thought. Another fact that any robot or human should have known.

There was something very strange going on here. And perhaps strangest of all, friend Caliban seemed quite unaware of the oddness of his own behavior.

All this flickered through his mind in an instant. “Well, I hope that I can be of more help. What is the difficulty?”

The strange robot hesitated for a moment, and made an oddly tentative gesture with one hand. “I am not sure,” he said at last. “That in itself is part of the difficulty. I seem to be in the most serious sort of trouble, and I don’t know what to do about it. I am not even sure who I am.”

How much stranger could this get? “You just told me. You are Caliban.”

“Yes, but who is that?” Caliban made a broad, sweeping gesture. “You are Horatio. You are a supervisor. You tell other robots what to do and they do it. You help operate this place. That is, in large part, who you are. I have nothing like that.”

“But, friend Caliban. We are all defined by what we do. What is it that you do? That is what you are.”

Caliban looked out across the wide expanse of the depot, pausing before he spoke. “I flee from those who pursue me. Is that all I am, Horatio? Is that my existence?”

Horatio was speechless. What could this be? What could it all mean? Beyond question, this situation was peculiar enough, and potentially serious, that he would have to give it some time. Things were running smoothly for the moment. Perhaps they would remain that way for a while. “Perhaps,” Horatio said gently, “we should go to another place to talk.”

THEY rode up the main personnel elevator toward the surface levels of the depot. They got off the elevator and Horatio led Caliban toward the most private spot he could think of.

The human supervisor’s office was vacant for the moment. Up until a few weeks ago, it had rarely ever been occupied. Humans hadn’t much need to come to the depot. But things were different now. Men and women were here, working, at all hours, designing, planning, meeting with one another. At times, Horatio thought that there was something quite stimulating about all the rushed activity. At other times, it could be rather overwhelming, the way the orders and plans and decisions came blizzarding down.

But any combination of confused and conflicting orders would be more understandable than this Caliban. Horatio ushered him into the luxurious office. It was a big, handsome room, with big couches and deep chairs. Humans working late often used them for quick naps. There was a big conference table on one side of the room, surrounded by chairs. At present, it had a large-scale map of the island of Purgatory on it. All the other rooms and cubicles and compartments of Limbo Depot were windowless, blank-walled affairs. But the north and south walls of the place were grand picture windows, the south one looking toward the busy aboveground upper levels of the depot, the northern one looking out toward the still-lovely vistas of Inferno’s desiccating landscape, prairie grass and desert and mountains and blue sky. The west wall was given over to the doors they had just come through, along with a line of robot niches, while the east wall was almost entirely taken up with view screens, communications and display systems of all sorts.

Caliban wandered the room, seeming to be astonished by all that he saw. He stared hard at the map upon the table, closely examined a globe of the planet that stood hanging in the air by the table. He stared out both windows, but seemed to take a special interest in the vistas of nature to the north.

But Horatio’s time was precious, and he could not let it drift away watching this odd robot stare out the window. “Friend Caliban—” he said at last. “If you could explain yourself now, perhaps I could be of assistance.”

“Excuse me, yes,” Caliban said. “It is just that I have never seen such things before. The map, the globe, the desert—even this sort of room, this human room—they are all new things to me.”

“Indeed? Pardon my saying so, friend Caliban, but many things seem new to you. Even if you have never seen these precise objects before, surely your initial internal dataset included information on them. Why do you seem so surprised by them all?”

“Because I am surprised. My internal dataset held almost no information at all, beyond language and the knowledge of my own name. I have had to learn about everything, either from a built-in datastore that works as a look-up system, rather than a memory, or by firsthand observation. I have found that I must rely far more on the second technique, as large and important areas of information have been deleted from the datastore.”

Horatio pulled out one of the hardwood chairs at the conference table and sat down, not out of any question of comfort, but so he could seem as quiet and passive as possible. “What sort of data has been deleted? And how can you be sure it was cut out? Perhaps it was never there in the first place.”

Caliban turned and faced Horatio, then crossed the room and sat in the chair opposite him at the conference table. “I know it was deleted,” he said, “because the space it should have occupied is still there. That space is simply empty. There are literally gaps in my map of the city, places that do not exist according to the map. Some gaps exist inside the city limits, but the land outside the city is nonexistent. The first time I went to the border of the city, I wondered what the ‘nothing’ beyond the city limits would look like.” Caliban pointed out the window. “The mountains I see out that window do not exist in my map. According to my map, there is nothing whatsoever outside the city of Hades. No land, no water, no nothing. Did your initial datasets tell you such things?”

“No, of course not. I awakened fully aware of the basics of geography and galactography.”

“What is galactography?” Caliban asked.

“The study of the locations and properties of the stars and planets in the sky.”

“Stars. Planets. I am unfamiliar with these terms. They are not in my datastore.”

Horatio could only stare. Clearly this robot was suffering a major memory malfunction. It could not be that a robot of such high intellect would be allowed out of the factory with such a faulty knowledge base. Horatio decided he must assume that any highly stressful event could send this Caliban over the edge. Horatio found himself fascinated by Caliban. As a management robot, it was his duty to oversee the mental health of the laborers in this section. He had made something of a study of robopsychology, but he had never seen anything like Caliban. Any robot who showed this degree of confusion and disorientation should be almost completely incapable of any meaningful action. Yet this Caliban seemed to be functioning rather well under circumstances that should have produced catatonia. What has Dr. Leving done to make him so strong and yet so confused? he wondered. “The terms ‘stars’ and ‘planets’ are not immediately important,” he said soothingly. “Are there any other major gaps? Any other subjects you feel that you should know more about?”

“Yes,” Caliban said. “Robots.”

“I beg your pardon?”

“My internal data sources say nothing at all about beings such as ourselves, beyond providing the identifying
