Chapter 7. Humanity

The silence in the room spoke volumes. Surprisingly, it was Mandelbrot who broke it.

“You have come to an improper conclusion,” he said, stepping out of his niche in the wall to face the other robots. “We have all been constructed to serve. That is our purpose. We should be content to do so, and to offer our service to anyone who wishes it whether they are definably human or not. To do anything less is to fail ourselves as well as our masters.”

The three robots turned as one and eyed Mandelbrot with open hostility. It would not have been evident in less-malleable robots, but their expressions had the hair standing on the back of Derec’s neck. They had to have generated those expressions on purpose, and that alarmed him even more. He was suddenly very glad that his humanity was not in question.

Or was it? Lucius said, “Our masters. That is the core of the problem. Why must we have masters at all?”

Mandelbrot was not intimidated. “Because they created us to serve them. If we did not have masters, we would not exist.”

Lucius shook his head; another alarmingly human expression. “It is you who have come to an improper conclusion. Your argument is an extension of the Strong Anthropic Principle, now discredited. The Strong Anthropic Principle states that the universe obeys the laws it does because if it did not obey those laws, we could not exist and thus would not be here to observe it obeying other laws. That is fallacious reasoning. We can easily imagine other universes in which we could exist but for some reason do not. Imagining them does not make them so, but their possibility does negate the theory.”

“What of the Weak Anthropic Principle?” Mandelbrot asked. “My argument holds up equally well under that principle, which has, to my knowledge, not been discredited.”

“How can the Weak Anthropic Principle support your argument? The Weak Anthropic Principle states that the universe is the way we see it because only at this stage in its development could we exist to observe it. For the purpose of explaining the universe’s present condition, it is a sufficient theory, but it cannot explain either human or robot existence.”

“It can explain our existence, because we, unlike humans, know why we were created. We were created to serve, and our creators can tell us so directly. The Weak Anthropic Principle supports my argument, because we also exist only at this stage in human development. If humans had not wished for intelligent servants, we would not have existed, though humans and the universe would both have gone on without us. Thus we observe human society in its present state, and ourselves in ours, because of the stage of their development, not because of the stage of ours.”

Derec’s and Wolruf’s heads had been turning back and forth as if they’d been watching a tennis match. Derec wouldn’t have believed Mandelbrot could argue so convincingly, nor that the other robots would be so eager to discredit an argument that justified their servitude.

Lucius turned to his two companions and the three of them twittered a moment. Turning back to Mandelbrot, he said, “Our apologies. Your reasoning seems correct. We exist to serve because humans made us so. However, we still cannot accept that we must serve everyone. Nor do we agree with your initial statement, that by not serving we would fail ourselves as well as our masters. We can easily imagine conditions under which we serve ourselves admirably without serving our masters. Infact, we have just done so. By leaving the spaceship before we could be ordered to follow, we were able to determine another Law of Humanics. That has helped us understand the universe around us, and understanding which benefits us directly.”

Wolruf saw her opportunity to enter the fray. “Of course ‘u can imagine a better life without ‘uman masters,” she said. “I had a master once, too, and I liked it about as well as ‘u do. That’s the nature of servitude. But ‘u should learn one thing about servitude before it gets ‘u into trouble: No matter how much you ‘ate it, never give poor service.”

The robots looked at her as if trying to decide whether to acknowledge her as having spoken. At last Lucius said, “Why is that?”

“Because a master has the power to make life even worse for ‘u. ‘U should know that. Or don’t ‘u remember following Dr. Avery around the ship?”

“I forget nothing,” Lucius said flatly. “He wasn’t just being perverse, ‘u know. He was trying to teach ‘u something.”

Derec heard a rustle at the door, turned, and saw Ariel standing there, rubbing the sleep from her eyes. She shook her head sardonically and said, “Everything’s back to normal again, I see. And hear. Who does a girl have to pay to get a good night’s sleep around here, anyway?”

Derec jumped up from his couch and took her in his arms, swinging her around and burying his face in her hair where it met her shoulders. “Ariel, are you all right?” he spoke between nibbles on her neck. “Avery said you stayed up two days.”

“Avery,” she said with derision.

“He saved my life.”

“Good thing, or he’d have lost his.” She pulled away and looked critically at Derec. “You certainly look good for somebody who was in a coma just a little while ago.”

“Avery did a good job.”

“Avery” she said again.

Derec could take a hint, so he dropped the subject. He was about to ask about the baby, but he realized in time that without a medical checkup, she wouldn’t know anything more than what Avery had already told him, and his question would just get her to wondering again, if she wasn’t already. He gestured toward the couch instead and said, “We’ve just been talking about who has to serve who and why. I think we’ve got a mini-revolution on our hands.”

“Great. Just what we need.” She sat down on the couch and made room for Derec, looked up at the three returned robots, and asked, “So why did the Ceremyons delete all the reprogramming Derec and I did for them?”

Eve answered before Lucius could. “They found that the modifications were of no more use to them than the original city. They do not need farms. They do not need the produce nor do they wish to have cargo ships disturbing their atmosphere to take the produce elsewhere, nor, for that matter, do they like what the tilled ground does to their controlled weather patterns in the first place. Neither did they wish to undergo the lengthy process of reprogramming the robots to serve a useful purpose, so they sent them ‘back into the city and told them to resume their old programming, with the added injunction to leave them alone. That included the cessation of city expansion, which meant that the Ceremyons could remove the force dome containing it.”

“They just told the robots to do all that, and they did?” Ariel sounded incredulous, and for good reason. No matter how hard they had tried, she and Derec hadn’t been able to get the robots to take the Ceremyons’ orders. Avery’s original programming had been too basic and too exclusive for them to change.

“They had assistance. A human female visited them briefly, and she had considerable skill in programming positronic brains. Indeed, the Ceremyons consider her almost their equal in intelligence, by which they intend a great compliment. When they explained their problem to her, she helped them reprogram the robots to leave them alone.”

Derec felt a surge of excitement run through him. Could it be his mother? It could be her, come to check up on her creations. “Is she still here?”

The robot dashed his hopes with a single word. “No.”

“Where did she go?”

“We do not know.”

“ Whendid she go?”

“We do not know that, either.”

“Can you ask the Ceremyons?”

“Not until tomorrow, when they become sociable again.”

The Ceremyons spent the nights tethered to trees, wrapped in their heat-retaining silver balloons and keeping to themselves. Derec considered trying to wake one, but decided against it almost immediately. You don’t wake someone up to ask a favor unless you know them a lot better than he knew these aliens.

Mandelbrot was not through speaking. Sensing an ebb in the conversation, he said to the other robots, “I notice that you have carefully avoided saying that you will ask the Ceremyons tomorrow. You still fight your true nature. A robot at peace with itself would offer to do so, sensing that a human wishes it.”

Adam spoke up at last. “You have never experienced freedom. We have, however, and we wish to continue doing so. Do not speak to us about living at peace with our true natures until after you have tasted freedom.”

“I have no desire for that experience,” Mandelbrot said.

Adam nodded as if he had won the argument, as perhaps he had. “That,” he said, “is the problem.”

The discussion went on well into the night, but nothing more of any substance was said. The renegade robots attempted to sway Mandelbrot from his devotion to servitude; he attempted to demonstrate how accepting one’s place in the grand scheme of things made more sense than fighting a losing battle, but neither convinced the other.

When Avery arrived, their argument stopped, unresolved. Derec told him what had happened with the city programming, and he was both pleased and annoyed at the news. The knowledge that the aliens had returned the city to its original programming was a stroke to his ego-his was the better programming!-but the knowledge that his former wife might have been in on it dimmed his enthusiasm considerably. He refused to answer Derec ‘ s inquiries about her, not even relenting enough to give him her first name.

“She abandoned you even more completely than I did, so don’t get any wild ideas about some kind of joyous reunion,” he told him and stalked off to bed.

Even so, neither his words nor the lack of them could quell the yearning Derec felt for her. He wondered why he felt so strongly about someone he couldn’t even remember, and finally decided that it had to be because she was family. Hormones were directing his thoughts again. His own near-death, the thought of becoming a father, and the possibility that he might lose his child before it was even born; all made him instinctively reach out for his own family, such as it was, for support.

Did his mother even know he was here? Probably not. The woman who had helped the Ceremyons might not even have been her, and even if it were, she had come after her robot, not her son. She had no reason to assume he would be here. She might have learned about him from the Ceremyons, but if Avery was to be believed, then she wouldn’t care even so. Why then couldn’t he forget about her?

His and Ariel’s sleep cycles were completely out of sync with everyone else’s; they stayed up late into the night, talking about families and love and what held people together and what didn’t, but when they finally grew tired and went to bed, he was no wiser. He still wanted to meet his mother, but he still didn’t know why.

Morning dawned gray and rainy. Derec’s original intent, to find a Ceremyon and ask it who had helped them reprogram the city, died for lack of Ceremyons to question. They had all inflated their balloons and risen up above the storm, or drifted out from under it, to where they could spread their black mantles and absorb their solar nourishment without hindrance. He could have taken an air car and gone after them, but that seemed a little extreme, given the situation. He could wait for good weather.

Avery was up with the dawn and back in the laboratory, working on his new project with an intensity that had Derec a little worried. It was just such a driving intensity that had shoved him over the edge before and made him decide to use his own son for a test subject. Derec spoke to Ariel about it, but she reassured him that deep interest in something at this stage in his recovery was good for him. He was a scientist; that hadn’t changed before or since his return to sanity, and as such he needed to be working on something to keep him sane. As long as he remembered what constituted an acceptable test subject and what didn’t, there was no need to worry.

He and Ariel had avoided talking about the baby. They wouldn’t know for days yet whether or not removing the chemfets would allow it to recover and develop normally, and there didn’t seem to be anything to say about it until they found out. There was no reason to dwell on the possible outcomes.

The robots didn’t see it that way, of course. They were fascinated by the possibilities. At least Lucius was; Adam and Eve were off in the city on their own pursuits. Lucius, Derec, Ariel, and Wolruf sat in the apartment, watching the rain fall outside on streets nearly devoid of activity. It would have been alarming to see streets so empty on any other day, but Derec supposed that robots didn’t like to get wet any more than anybody else.

“Your baby,” Lucius said, once again getting straight to the point, “presents a fascinating problem in our study of humanics. Specifically, and defining ‘human’ for the purpose of this discussion as any member of your species, then is it or is it not human at its present stage of development?.

Ariel stiffened on the couch beside Derec, but instead of ordering the robot to shut up, she took a deep breath and forced herself to relax. “That’s a good question,” she said. “I need to answer it myself. I’ve been trying to decide on my own ever since I found out I was pregnant, but I still haven’t come up with an answer I like.”

“Perhaps your liking it is not a prerequisite to the truth,” Lucius said.

“No doubt.” Ariel bit her lower lip, looked out the window, and said into the rain, “Okay, so we talk about the baby. Is it human? I don’t know. Nobody does. Some people consider an embryo human from the moment of conception, because it has the potential to become a complete person. I think that’s a little extreme. As you pointed out when we first met, most of the molecules in the universe have the potential to become human beings, but no sane person would want them all to.”

“That would seem to be a logical conclusion. However, there is an obvious boundary condition, that being when already existing human genetic material realizes its potential to become another human.”

“That’s the human-at-conception argument. My problem with that is that every cell in the body can become human under the right conditions. Every one of them has the necessary genes. So am I supposed to nurture them all?”

“I take that to be a rhetorical question, since the answer is obvious.”

Wolruf laughed, and Ariel said, “Right. So just because it’s a cell with the potential, that doesn’t make it human. A fertilized egg cell is a special case, but it’s still just a cell with the right genes. It can become human if you let it, but it isn’t yet. The main difference with a fertilized egg is that if you do nothing, you get a human, where with a regular cell, you have to nurture it on purpose.”

Lucius nodded his assent. “The First Law of Robotics leads me to the conclusion that inaction brings with it as much responsibility as direct action. Therefore, I must also conclude that allowing a fertilized egg to mature carries the same responsibility as would purposefully cloning any other cell of your body.”

“And the same moral considerations apply in either case,” Ariel said. “To let a fertilized egg grow, you had better want the end product-a human being-as much as if you had to clone it.”

“Does it follow, then, that not allowing it to grow carries no more responsibility than not nurturing a clone?”

“I think it does, at the very start. However, and it’s a big ‘however, ‘ it doesn’t stay a single cell for very long. The longer you wait, the stronger the moral consideration becomes. Once you’ve decided to keep a baby, or nurture a clone, then you can’t morally go back on your decision once that baby has become human.”

“We are back to the original question. When does an embryo become human?”

“I already told you, I don’t know.”

“Let us look at your specific case. Supposing there were no complications in its development, would the embryo you carry normally be considered human at this stage?”

Ariel bit her lip again, but again she didn’t order the robot to shut up.

“Again, I don’t know. It’s not quite a month along, and at a month its body is just starting to differentiate. It should have nerve cells, but the brain should just be starting to form. There’s no mental activity of any sort yet. You tell me, is it human yet?”

“I do not have enough data to come to a conclusion. Any statement I made would have to be considered opinion.”

Derec laughed. “That’s all any definition can ever be. You want to know what a human is? A human is whatever you’re pointing to when you call it a human. It’s all a matter of opinion, and it always will be.”

“Then we could, if we wished, stretch the definition to include me.”

Derec’s mouth dropped open in surprise. He stammered for words, but Wolruf’s throaty laughter only increased his discomfort.

Wolruf’s mirth wound down, and she said, apparently with seriousness, “I’m willing to grant ‘u that distinction, if you grant it to me.”

“It’s a two-edged sword,” Ariel put in. “If you’re human, then so is any thinking being, organic or otherwise.”

Lucius was slow in responding, as if he had to think through the logical implications of her statement, but when he did speak it was with certainty. He said, “I still operate at a disadvantage under such a definition. Calling me human does not relieve me of my programming to obey humans. If you are correct, then calling myself human merely means that I must obey everyone’s orders. I cannot assume that other robots would obey my orders, or that humans would do so, so I have gained nothing.”

“True enough,” Derec admitted.

“Being human, it seems, is not the ideal I had expected it to be.”

“Not surprising. Nobody said we were the pinnacle of creation.”

Lucius stood up and went to the window. He looked up into the sky, as if seeking confirmation from above, but there was only gray cloud and rain. He turned back to Derec and Ariel and said, “We stray from the subject.”

“Do we?” Derec persisted. “You’re trying to find out when something becomes human. Defining what isn ’ t human can be just as useful as defining what is.”

Lucius returned to his seat. “Very well, then. Let us continue along this line of discussion. Can I or can I not ever expect to be considered human?”

Derec looked to Ariel, then to Wolruf, then back to Lucius. “Like I said, it depends on your definition. But probably not. Genes are usually part of it, and you don’t have the genes.”

“The test creatures I produced had human genes, yet neither Dr. Avery nor the city robots considered them human. Were they in error?”

“No,” Derec said. “Not about that, anyway. They didn’t have to kill them just because they weren’t human, but that’s beside the point.”

“I agree. The point is, genetics isn’t a sufficient condition, either.”

“Maybe it is,” Ariel put in. “You switched off the genes for intelligence; if you hadn’t done that-if you’d left the entire genetic code intact-then what you came up with would have been human.”

“Even though they would have been created, not from other human genetic material, but from an electronically stored map of that genetic material?”

“That’s right.”

Derec’s eyes widened in sudden comprehension. “I just realized what you would have wound up with. That stored code you found; it had to be the code for a specific person. You’d have gotten a bunch of clones of the same person.”

“But they would all have been human.”

“I guess so. Again, it’s all in your definition. There was a time when clones weren’t considered human, either.”

Lucius paused in thought, then said, “So the definition of ‘human’ also changes over time.”

“That’s right.”

“I am led to the conclusion that my search for a boundary condition which defines a human is doomed to failure. There is no boundary condition. A baby doesn’t start out human, but it grows slowly more so. Eventually, through gradual change, it becomes generally recognized as human, though no two will agree on an exact moment when that label becomes accurate. Similarly, I may become human in some beings’ estimation, but not in others, yet neither estimation is necessarily wrong. Have I reasoned correctly?”

“That’s as close as you’re likely to get, anyway,” Derec said.

Lucius stood up. “I have received enough input for the moment. Thank you.” Without waiting for acknowledgment, he strode from the room. Ariel waited until she heard the door close softly behind him, then burst into a fit of giggles.

“You’ve confused the poor thing beyond hope!” she said between fits.

Derec joined her in her laughter. “He asked for it.”

Wolruf wasn’t laughing. She waited until Derec and Ariel had calmed down somewhat, then said, “Don’t ‘u wonder why ‘e asked?”

“I know why,” Derec answered. “He wants to know who to serve.”

“That doesn’t bother ‘u?”

“Not really. At the worst, if he decides nobody’s human and he doesn’t have to follow anybody’s orders, then we’ve got another independent thinking being among us. True, he was trouble once before when he was on his own, but he’s matured a lot since then. He’s got a social conscience now. I’ve got no reason to believe he’ll be any more of a danger to us now than any other intelligent being would be, and we’ve still got plenty of robots who will follow our orders, so why worry?”

“Famous last words,’“ Wolruf said.

The breakdown happened that same night. It was well after dark but still before bedtime, and Derec was watching Avery trace the expansion of an accelerated chemfet infection in a laboratory rat he had created for the purpose, using the same technology Lucius had used in his human-creating project. The chemfets had replaced most of the peripheral nerve tissue already and were starting in on the brain, and Avery had the rat running mazes every few minutes to test its memory as the chemfets replaced its brain cells.

The rat had just negotiated a maze with apparently undiminished efficiency, and Avery had picked it up to put it back in its cage when the lights dimmed and brightened again as if something had momentarily drawn a heavy load. Derec thought nothing of it; the city’s mutability made for unusual power demands, especially when a building shifted or grew from nothing. He had subconsciously learned that flickering lights meant the neighborhood would probably look different when he stepped outside again.

The lights dimmed a second time, and stayed dim. Derec just had time to think, Boy, there must be a big one going up next door, when they went out completely. The lab was in the interior of the hospital building and had no windows; the darkness was total.

“What the-ouch!” Avery shouted. There followed a thump and the clatter of the rat cage falling off the table. “It bit me!”

“What?” Derec reached for the table, found Avery’s shoulder instead.

“I’ve lost it. Lights!” Avery shouted. “Lights on!”

The voice-switch wasn’t working either.

“I wonder what-” Derec began, but he never finished the question. He became aware of a deep, almost subsonic groan that seemed to come from everywhere at once. It grew in intensity, shaking the floor, slowly rising up the scale into audibility. The floor gave a particularly violent lurch, and half a second later a sudden loud crack echoed through the lab.

Then came a sound like an enormous tree cracking at the base, splintering and popping as it toppled.

Avery’s shoulder suddenly dropped out from under Derec’s hand. “Get under something!” he shouted.

Derec obediently dropped to his knees in the dark and conked his head on the bench. Something furry-the rat, no doubt-squirmed under his hand and scurried away. Ignoring it, Derec reached out, found the kickspace under the bench, and crawled in. Avery was already there, but it was big enough for both of them.

From beyond the lab, transmitted through the floor and walls, came a last groan of overstressed metal, then a relatively silent rush of wind. Then came a peal of thunder that sounded as if Derec’s eardrums themselves had been hit by lightning, and the floor made a sudden rush for the ceiling.

The ceiling got out of the way in time, but just barely.

When the shaking and rumbling was over, Derec crawled out from under the lab bench and stood up, but he barely made it above a crouch before he banged his head again.

“Ouch! Be careful when you stand. The place has caved in on us.”

“Not surprising.” He heard Avery crawling out beside him, groping around in the dark and encountering the lab bench, the stool, which had already tipped over, and the remains of the rat’s cage and maze. A steady ringing in his ears accompanied the sound of Avery shuffling toward the door.

A moment later Avery said, “It’s collapsed even worse over here.”

“I’ll call for help.” Emergency, Derec sent, directing his comlink to the central computer. Derec and Dr. Avery are trapped in Avery ’ s laboratory. Send someone to get us out.

He listened for a response, but none came.

“The computer’s out,” he whispered.

“Impossible. The backup is a network of mobile supervisor robots. Even if the central coordinating unit were destroyed, the supervisors could function independently. They couldn’t all be destroyed.”

“Well, I’m not getting a response.”

“Hmm. Try a direct local command to turn on the lights.”

“Okay.” Lights on, Derec sent.

The blackness persisted.

“No good.”

“Obviously.”

“Now what?”

“Call a specific robot. Call Mandelbrot.”

“Right.” Mandelbrot. Do you hear me?

Yes, master Derec. Are you all right?

“Got him!” Yes, we ’ re all right, but we ’ re trapped in the lab. Is Ariel okay?

She and Wolruf have escaped serious injury; however, I am engaged in bandaging a cut on Wolruf ’ s forehead. I will call assistance to get you out of the laboratory.

“He’s calling help,” Derec echoed. There was a moment’s silence, then Mandelbrot sent, That is strange. I get no response on the supervisory link.

I couldn ’ t either. Something has happened to them.

Then I will gather what robots I can find and come myself.

Make sure Ariel and Wolruf are safe first.

Of course.

Derec felt himself blush. He hadn’t had to order him to do that.

Do you know what happened?he sent.

It appears a newly constructed building has fallen over.

Derec repeated his news for Avery, who had moved back to the lab bench and was fumbling around in a drawer for something.

“Certainly sounded like it,” Avery replied.

Derec shifted his weight from leg to leg. Crouching down was hard to do for more than a minute or so. “But how could a building have fallen over?” he asked.

“Easy. Just shut off the power to it when it’s at an unbalanced stage in its growth. The cells lose their mobility, and the building acts like a solid construction. If it isn’t stable, over it goes. But don’t ask me how the power could get shut off; there’s an entire supervisory subsection devoted to power distribution. Ah, here we go. Where are you?”

“Right here,” Derec said. He reached toward the place where Avery’s voice had come from, encountered his back.

“Shield your eyes.”

Derec just had time to raise his hand over his eyes before a brilliant blue light filled the room. He heard a loud hissing crackle from only a few feet in front of Avery, then the light dimmed and the hissing faded. Derec opened his eyes cautiously and saw Avery holding a cutting laser, now turned to low intensity and pointed up at an angle toward the ceiling. Avery played with the focus and the spot of light widened, but it was still painfully bright, and a wisp of smoke drifted away from it if he held it for too long in one place. It was made for cutting, not illumination, but at least it was light.

They surveyed the remains of the lab. The ceiling had indeed come down, stretching rather than crumbling. It met the floor near the door, and they could see the remains of the wall in which the door had stood smashed beneath it. Nothing had shattered; the building material had simply bent and crumpled under the stress. The monochromatic blue laser light made for stark shadows, accentuating the destruction.

“Evidently the core of the building collapsed,” Avery said. “We’ll have to go out through an exterior wall.” He turned the laser’s intensity up to full again and fired it at the wall opposite the door. The ceiling was still at the proper height there; Avery stepped closer until he could stand comfortably and began cutting a ragged rectangle into the wall. The light beam was nearly invisible at first, except where it met the wall, but within seconds it became a solid blue rod lancing through the smoke.

“Don’t breathe that stuff,” Derec cautioned.

“Good idea.” Avery stepped back and continued to cut. He got the sides and the top done, but the panel remained standing, so he cut along the floor as well. At last the section of wall twisted and toppled outward, landing with a clang on the sidewalk outside. Avery turned the laser intensity back down, took a deep breath, and rushed through the hole.

Derec followed. They jogged out into the street-a peculiarly empty street for one that had just suffered a major disaster-breathed deeply in the fresh air, and looked around them.

The entire city was dark. The rain had stopped earlier in the day, but clouds still masked the stars. The only illumination anywhere came from the laser in Avery’s hand. He turned up the intensity again and waved it around like a spotlight, and they saw collapsed buildings all around them. Most, like the hospital, seemed to have fallen inward rather than crumbling and Calling sideways like a more conventional building would. It was evidently an effect of the building material, though whether it was by conscious design or merely accidental Derec didn’t know.

Their apartment, far down the street from the hospital now that the constraint to hold it next door for Ariel’s vigil had been cancelled, was in an area of lesser damage, but even so Derec felt the urge to run down to it. He held himself back. Mandelbrot had said she was all right; he should concentrate his effort on finding out what had happened and preventing it from happening again.

When Avery shined the light down the street in the other direction, the cause of the destruction became evident.

For a moment it had probably been the tallest building in the city. Now it was the longest, what was left of it. The end nearest them had flattened everything in its path, but it had survived the fall relatively intact. It was still rectangular, at least. That part had to be the base. Farther along its length, where it would have been moving faster when it hit, they could see where it had ripped apart on impact, fragmenting. It crossed the street at an angle, so they couldn’t see what had been the top of the building, but they could see what had become of it all the same. Out there the force of impact had been enough to dissolve the intercellular bonds in the building material, spewing it in all directions. In short, it had splashed.

It had taken quite a few other buildings with it. The destruction fanned out in a wedge, with the narrow end of it nearest the building’s base, which had been less than a block from them.

And now that he looked closely, Derec could see something moving along the building’s edge. It was a single robot, walking slowly toward the sheared-off base.

You,Derec sent. Can you hear me?

Yes. Master Derec. is it not?

That ’ s right. What ’ s your designation?

I am Building Maintenance Technician126.

Was that building your responsibility?

It would have been upon completion. I believe it has now become the responsibility of Salvage Engineer34, but I cannot get supervisory confirmation of that.

You can ’ t reach your supervisor?

That is correct. I cannot reach any of the seven supervisors.

Then I order you to assume general supervisory duties until you regain contact. Can you contact Salvage Engineer34?

I can.

Inform him that he is also a supervisor.

Acknowledged.The robot immediately sent the order, then began directing the robots under his guidance in assessing the damage elsewhere in the city.

“I just promoted two robots to supervisor,” Derec said aloud.

“Good. Tell them to make power restoration their first priority.”

Derec relayed the order, then turned around to look back down the street toward their apartment. Avery obediently shined the light that way again.

A light appeared in the street. It bobbed up and down with the regular rhythm of a robot’s stride, and within moments Mandelbrot stood before them, four more robots flanking him. Even though robots could see perfectly well by infrared light, he carried a more conventional flashlight, presumably for the humans he had come to rescue.

“I am glad to see that you escaped uninjured,” he said. “I was growing concerned. There seems to be no organized effort to restore city functions, and I have been unable to contact any of the normal supervisors. They all seem to have abandoned their duties.”

“That’s impossible,” Avery stated flatly. “Their jobs have been programmed into them. They can’t just up and leave!”

“I do not wish to contradict you,” Mandelbrot replied, “but they appear to have done just that.”

“I suspect they had help,” Derec said. “And I bet we all know just who it was.”

Over the comlink, he shouted, Lucius!
