But no, it was inaccurate to say that there was no difference between day and night. There was no change in the amount of traffic on the streets and walkways, but there was a huge change in the character of that traffic. Now, late at night, the people were all but gone, but the robots were here.
Caliban looked about himself, at the proud, brightly lit, empty towers of Hades, the grand boulevards of magnificent and failed intentions. But the heart of that world, that city, was empty, barren.
Yet the unpeopled city was still crowded. Humans had been a sizable minority during the day, but in the wee hours of the night, it was robots, robots, everywhere. Caliban stood in the shadow of a doorway and watched them all go by. These robots of the night were different from the daytime robots. Almost all of those had clearly been personal servants. In the night, the heavy-duty units came out, hauling the heavy freight, working on construction jobs, doing the dirty work while there were fewer humans around to be disturbed by it.
A gang of huge, gleaming black construction robots trudged down the street, past Caliban, toward a tall ivory-colored tower, half-finished and yet already lovely. But there were already half a dozen equally lovely towers within a few blocks of where Caliban stood, all of them virtually empty. Across the street, another gang of robots was hard at word disassembling another building that seemed scarcely any older or more used.
Caliban had seen many other work crews come out in the last hour or so, likewise doing needless maintenance work: searching for litter that was not there; polishing the gleaming windows; weeding the weedless gardens and lawns of the parks; busily keeping the empty city core shining and perfect. Why were these robots not employed in the emptier, threadbare, worn and dirty districts, where their work could have some meaning? Why did they work here?
The empty city. Caliban considered the words. They seemed to echo in his head. There was something wrong with the very idea of such a place. From his datastore, from the emotions of whoever had loaded the store, came the sure, certain knowledge that cities were not meant to be so. Something was going desperately wrong.
Another piece of data popped up from the datastore, a straight, solid fact, but the ghosts of emotion hung about this one fact more strongly than any other emotion he had absorbed. It was the thing that the person who created his datastore cared about most of alclass="underline" Every year the total human population went down—and the robot population went up. How could that be? he wondered. How could the humans allow themselves to get into such a predicament? But no answer came up from the datastore. For no reason that he could understand, the question, though it had nothing to do with him, was suddenly of vital importance to him.
Why? he wondered. And why do I wonder why? Caliban had noted that most robots he observed had a distinct lack of curiosity. Few were even much interested in their surroundings. Something else, yet again, that set him apart. When his maker had molded his mind into an oddly shaped blank, had that maker also blessed him and cursed him with an overactive degree of curiosity? Caliban felt certain it was so, but in a way it did not matter. Even if his sense of curiosity had been deliberately enhanced, that did not stop him from wondering all the same.
Why, why, why did the robots blindly, needlessly, build and disassemble, over and over, rather than leaving things as they were? Why create huge buildings when there were none to use them? Madness. All of it madness. The voice of the datastore whispered to him that the city was a reflection of a society warped, twisted, bent out of any shape that could make normal life and growth possible. It was opinion, emotion, propaganda, but still, somehow, it spoke to him.
The world was mad, and his only hope of survival was to blend in, be accepted as one of the inmates of this lunatic asylum, get lost among the endless robots that tended to the city and its inhabitants. The thought was daunting, disturbing.
Yet even perfect mimicry would not protect him. He had learned that much, almost at the cost of his existence. Those Settlers last night had clearly meant to kill him. If he had acted like a normal robot, he had no doubt that they would have killed him. They had expected him to stand placidly by and permit his own destruction. They had even thought it possible that he would willingly destroy himself on the strength of hearing that weak and tortuous argument about how his existence harmed humans. Why had they thought that strained line of reasoning would impel him to commit suicide?
Caliban stepped out from the shadowy doorway and started walking again. There was so much he had to learn if he was to survive. Imitation would not be enough. Not when acting like a standard robot could get him killed. He had to know why they acted as they did.
Why was he here? Why had he been created? Why was he different from other robots? How was he different from them? Why was the nature of his difference kept hidden from him?
How had he gotten into this situation? Once again, he tried to think back to the beginning, to search through the whole recollection of his existence for some clue, some answer.
He had no memory of anything whatsoever before the moment he came on, powered up for the first time, standing over that woman’s unconscious body with his arm raised from his side. Nothing, nothing else before that. How had he come to be in that place, in that situation? Had he somehow gotten to his feet, raised his arm, before he awoke? Or had he been placed in that position for some reason?
Wait a moment. Go back and think that through. He could see no compelling reason to assume that his ability to act could not predate his ability to remember. Suppose he had acted before his memory commenced? Or suppose his memory prior to the moment he thought of as his own awakening had been cleared somehow? Alternately, what if, for some reason, he had been capable of action before his memory started, and his memory had simply not commenced recording until that moment?
If any of those cases were possible, if the start of his memory was not a reliable marker for the start of his existence, then there were no limits to the actions he might have taken before his memory began. He could have been awake, aware, active, for five seconds before that moment—or five years. Probably not that long, however. His body showed no signs of wear, no indication that any parts had ever been replaced or repaired. His on-line maintenance log was quite blank—though it, too, could have been erased. Still, it seemed reasonable to assume that his body was quite new.
But that was a side issue. How had that woman come to be on the floor in a pool of blood? It was at least a reasonable guess that she had been attacked in some way. Had she been dead or alive? He reviewed his visual memories of the moment. The woman had been breathing, but she could easily have expired after he left. Had the woman died, or had she survived?
The thought brought him up short. Why had he not even asked himself such questions before?
Then, like twin blazes of fire, two more questions slashed through his mind:
Had he been the one who attacked her? And, regardless of whether or not he had—was he suspected of the attack?
Caliban stopped walking and looked down at his hands.
He was astonished to realize that his fists were clenched. He opened out his fingers and tried to walk as if he knew where he was going.
THE night before, Alvar Kresh had taken a needle-shower in hopes of helping him to sleep. Tonight he took one in hopes of waking up. He was tempted to watch the recording of Leving’s lecture while sitting up in bed, but he knew just how tired he was, and just how easy it would be for him to doze off if he did that. No, far better to get dressed again in fresh clothes and watch on the televisor screen in the upper parlor.
