Redundancy

This story was originally commissioned for UNIX magazine. New intelligent software had been developed that allowed a computer to make decisions not only based on a predetermined set of standards, but also by appraising and evaluating situations and reaching an appropriate conclusion on its own. Similar software helps the Mars rovers to navigate independently while out of the range of communication with Earth.

The tale never appeared in UNIX magazine because, according to the editor who commissioned it, his superiors felt that a science‑fiction story was not appropriate for a venue that dealt with actual science. This would, I think, be news to several generations of scientists, engineers, and researchers who have ofttimes been inspired by the science‑fiction stories they read while growing up.

In composing stories, I frequently have to try to put myself in the mental and physical position of various aliens. Though designed by humans, nonhumanoid machines still qualify as perfectly alien. What, really, is your computer thinking when you put it, and yourself, to sleep? Relying entirely on the standards and practices that have been programmed into it, how could one possibly make what in the last analysis amounts to a moral or ethical decision?

In Tom Godwin’s classic SF story “The Cold Equations,” a human is forced to make a life‑or‑death decision in a machine‑like fashion.

What if the reverse were true?

Amy was only ten, and she didn’t want to die.

Not that she really understood death. Her only experience with it had come when they had buried Gramma Marie. Now the funeral was a wisp of a dream that hung like cobweb in the corners of her memory, something she did not think of at all unless it bumped into her consciousness accidentally. Even then it was no more than vaguely uncomfortable, without being really hurtful.

She did not recall a lot about the ceremony itself. Black‑clad grown‑ups speaking more softly than she had ever heard them talk, her mother sobbing softly into the fancy lace handkerchief she never wore anywhere, strange people bending low to tell her how very, very sorry they were–everything more like a movie than real life.

Mostly she remembered the skin of Gramma Marie’s face, so fine and smooth as she lay on her back in the big shiny box. The fleshy sheen mirrored the silken bright blue of the coffin’s upholstery. Such a waste of pretty fabric, she remembered thinking. Better to have made skirts and party dresses out of it than to bury it deep, deep in the ground. She liked that idea. She thought Gramma Marie would have liked it, too, but she couldn’t ask her about it now because Gramma Marie was dead, and people couldn’t talk to you anymore once they were dead. Not ever again. That was the thing she disliked most about death: not being able to talk to your friends anymore.

Thinking about it made her shiver slightly. She knew she was in big trouble, and she didn’t want to end up looking like Gramma Marie.

The potato vines and the carrots and the lettuce had not yet begun to die, though the leaves on the fruit trees were already starting to droop. Some had been killed by the explosion, torn to bits or ripped up and hurled violently against one another. One of the big pear trees had been blown to splinters. Smashed pears lay scattered across the floor like escapees from a Vermeer still life. Amy knew that the others would start dying soon, now that the hydroponic fluid that nourished their growth had stopped circulating and the special lights used to simulate the sun had gone out. The heaters were off, too, though some residual warmth still emanated from their internal radiant elements. The temperature was falling steadily, soaked up by the thirsty atmosphere of the rapidly cooling station module.

What really frightened her, though, was not the darkness or the gathering cold. It was the persistent, angry hiss that came from the base of the wall at the far end of the module. She couldn’t see the leak, but she could hear it. She tried putting some empty sacks over the hiss and then piling furniture on them. It muted the noise, but did not stop it. So she backed as far away from it as she could, all the way back across the room, as if retreating from a dangerous snake. There were four safety doors in the big module, designed to divide it into airtight quarters in the event of a leak. Not one of them had closed. She didn’t know why, but she guessed that the explosion had broken something inside them, too.

She wondered if she would know it when the air finally ran out.

She would have asked Mr. Reuschel about it, but he was already dead. He did not look at all like Gramma Marie had. His mouth hung open and instead of lying neat and straight on his back he was all bent and twisted on the floor where the explosion had thrown him. She didn’t know for certain he was dead, but she was pretty sure. He did not reply to any of her questions and he didn’t move at all, not even when she touched his eye. When she put her palm up to his mouth the way she had been taught to in school she couldn’t feel anything moving against her skin.

He had been the gardener on duty when everything had blown up. Daddy called him a hydroponics engineer, but Amy just thought of him as the gardener. Ms. Anwalt was the other gardener. Like everyone else on the station she probably knew about the explosion by now and would be anxious to check on the garden, but she couldn’t. No one could because the access door didn’t work anymore. The explosion had broken it just like it had broken Mr. Reuschel.

The door led to the lock, that led to the service corridor, that connected the hydroponics module to the rest of the station. Amy knew it was still connected because her feet were not floating off the floor. If the module had broken away from the rest of the station then it wouldn’t be swinging around the central core, and if it wasn’t rotating around the central core then she would be floating in zero‑g right now.

She wondered if Jimmy Sanchez was worried about her. She hoped so. Jimmy was twelve, the only other kid on the station. His parents were photovoltechs who spent their days drifting like butterflies around the huge solar panels that powered and heated the facility. Jimmy was pretty nice, for a boy. She liked him more than he liked her, but maybe, just maybe, he was thinking about her.

She knew Mom and Dad must be worrying about her, but she tried not to think about that because it made her sad. She thought of all the bad things she had done as a little girl and wished now she hadn’t done them.

It was getting cold, and she knew she should keep moving.

She walked over to the rectangular port behind the tomato vines. Since all the overheads had gone out, the only light in the module came from the ports. Pressing her nose to the transparency allowed her to see the big blue sphere of the Earth outside, rotating slowly around the port. Doing geography helped keep her mind off the chill. She located Britain and Spain and the boot of Italy. There was no cloud cover over the Alps and she saw the snow on the mountaintops clearly. But the oceans were easiest to identify. They made her think of beaches, and the stinky‑sweet smell of saltwater, and the warm summer sun.

She was able to see her breath by the light of the Earth. Mr. Reuschel still hadn’t moved. He did not protest as she struggled to get his jacket off. He was a grown‑up and heavy and hard to move, and it made her stomach feel queasy to try, but she kept pushing and shoving. His jacket was bulky‑warm and covered her down to her knees.

Water dripped from a broken pipe, a comforting sound in the darkness. She drank and then did her best to wash the dirt off her face, the dirt from where she had landed. She understood enough to be thankful for it. If the compost pile hadn’t been there to catch her and break her fall, she might be as twisted up as Mr. Reuschel.

After a moment’s thought she decided to sit down by the door. All of its internal LEDs had gone out so she knew it still wasn’t working. The big manual lever was bent and twisted and wouldn’t move even when she put all her weight against it.

It was very dark next to the door and away from the ports but somehow she felt better sitting there. Pouring through the ports, Earthlight made shadowy silhouettes of the injured trees and bushes. The cabin in Residential Module Six with her stuffed animals and seashells and snug second‑tier bunk seemed very far away. It would have been easier if Jimmy, or anybody, had been there with her. But they weren’t. There was only poor Mr. Reuschel, and he was worse than no company at all. She was alone.

Except she wasn’t.

There was another presence in the module. It wasn’t dead, but it was not really alive, either. Awareness is a matter of technical definitions and predetermined perceptive capability. Consciousness is something entirely more abstract.

Molimon was aware of her presence but could not talk to her, could not provide reassurance or comfort. It was aware of the damage that had occurred, of Mr. Reuschel, of the falling temperature and absence of light. It had detected the leak at the far end of the module and continued to monitor the rate at which air was being lost. It was aware of everything around it. That was the job it had been assigned to do. That was the job it did well.

Until now. It knew that the environment in which it operated had undergone an abrupt and drastic change. There was damage and destruction everywhere. Nothing was functioning within assigned parameters and try as it might, Molimon could not restore anything to normal.

That was because it had suffered considerable damage itself. A pair of memories were gone, and an IOP processor had been popped by the force of the explosion. Two molly drives had stopped spinning. Efficiently, effectively, Molimon distributed the responsibilities of the damaged sectors among the components of itself that continued to function. It was wounded, but far from dead.

Internal communications continued to operate, allowing Molimon to send details to Command Central of the damage it and the module had suffered. So far there had been no response. No doubt Central was concentrating on assessing the damage to those components and parts of the station that were unable to report on themselves. Knowing that Molimon could take care of itself, Central would take its time responding.

Having reported the damage and requested instructions on how to begin repairs, Molimon rested and waited for a reply. It could not wait long. If no instructions were forthcoming, it would have to shut itself down while battery power remained, thereby preserving its programming and functions until full external power was restored. This caused it no concern. Anxiety was not part of its programming. It had no concept of unconsciousness. Shutdown was merely another state of existence. There was nothing to be concerned about, since all systems within the module were fully redundant.

It was aware of the damage to the hydroponics module only in purely quantitative terms: the absence of light, of heat, of equipment functioning efficiently and according to plan. Supervising the hydroponics environment was but one component of its mission, and it could not bring anything back online until power was restored. Knowing this, it completed its observations, allotted them a sector on one of its still‑functioning mollys, and made a complete record of the situation. Programming now called for it to commence an orderly shutdown while sufficient reserve power remained for it to do so.

It did not. Unexpectedly an important component of the module still functioned.

Hedrickson studied the readouts and listened to the human static that filled his headphones. The various speakers were angry, frustrated, anxious. He worked at the console unaware that he was gritting his teeth. They were starting to hurt, but he didn’t notice the discomfort. Just as he did not immediately take notice of the hand that came down on his shoulder.

“How’re we doing?”

Pushing the phones off his ears, he leaned back in the chair and stared dully at the monitors. “It’s slow. Real slow. The corridor’s a mess. They’re clearing it as fast as possible but they can’t use heavy tools in there or they’re liable to hull the tube.”

“Doesn’t matter, if they’re working in suits.” Cassie’s gaze flicked over the readouts. The figures were not reassuring.

“They’re afraid any explosive decompression might weaken the tube’s joints to the point where they could snap. Engineering already thinks that the initial explosion may have compromised structural integrity where the corridor attaches to the module’s lock. If that goes, we could lose the whole thing.” His tone was leaden, tired, indicative of a man who needed sleep and knew he was not going to get any. “How’re the Maceks taking it?”

Cassie Chin shrugged helplessly. “Tina’s in shock. They took her down to the clinic and put her under sedation. Iwato’s watching her closely. I think he’s pretty worried about her.”

“Damn it. What about Michael?”

“Couple of the riggers volunteered to stay with him. They had to lock down the main bay to keep him from going out in a suit.”

Hedrickson’s fingers drummed nervously on the console. “How much do they know?”

“They’ve figured out Amy’s in there somewhere. They know the lights are out and the heat is going, that the AV lines are down and that no one inside is responding to queries through the board.”

The engineer exhaled slowly. “Do they know about the leak?”

“No.” Cassie stared at him. “That I couldn’t tell them. Nobody else is up to that, either. They’ll find out when the crew goes in. There isn’t much hope, is there?”

“I’m afraid not. The rescue specs are working like maniacs, but even if the leak doesn’t get any worse, the air in there’ll be gone before they can cut the door. Morrie Reuschel was engineer on duty when it happened. We haven’t heard from him. If he’s that badly hurt, then the girl…” His words trailed off into inaudibility, foundering in despair.

“The only communication we have with the module is via its independent Module Lifesystems Monitor. It says it got wanged pretty good, but you know how much redundancy those suckers have built into them. It took stock of its losses and shifted all necessary functions to undamaged components outside the module. That’s the only reason we have some idea of what’s going on inside. One boardline survived the damage, so we’re still getting reports.”

The woman frowned. “But there’s no power to the module.”

“The section there is operating on standard multiple battery backup.”

“I know.” She leaned curiously over the console. “But it shouldn’t be. It’s designed to render a report and then shut itself down to preserve programming and functions if it loses primary power. Something else is wrong. Has it requested repair instructions yet?”

“I would imagine.” Hedrickson checked a readout. “Yeah. Right here. Haven’t been sent out, though.”

“Why not?”

“Central’s dealing with more serious damage elsewhere.”

Chin straightened. “Instead of cycling through shutdown the way it’s supposed to, it keeps requesting repair instructions. There’s got to be a reason.” She thought furiously. “Can you override Central from here?”

Hedrickson frowned at her. “I think so, but you’d better have a damn good reason for messing with prescribed damage‑control procedure.”

“As a matter of fact I don’t have any reason at all. But it seems as if the Molimon does. If its internal diagnostics are functioning well enough to tell you what’s wrong, can you send it the necessary instructions on how to fix itself?”

“Why bother? Just so I’ll have something to tell the board of inquiry.”

“I just told you: It’s got to have a reason for not shutting itself down.”

Hedrickson looked dubious. “You’ll take the responsibility?”

“I’ll take the responsibility. See what you can do, Karl.”

The technician bent to work. Cassie stood staring at the wall. Halfway around the station the darkened, leaking module swung precariously on the end of its access tube, to all intents and purposes dead along with everything it contained. Dead except for one semi‑independent device, which was disobeying procedure.

Computers do not act on whims, she thought. They respond only according to programming. Something was affecting the priorities of the Molimon unit that supervised the hydroponics module. But it could not proceed without apposite human directives.

Sometimes you just had to have faith in the numbers.

The darkness and gathering chill did not trouble the Molimon. It was immune to all but the most extreme swings of temperature. Reserve power continued to diminish. Still it did not commence shutdown.

Information on how to effect necessary repairs finally began to arrive. Gratefully the incoming instructions were processed. The problem with the critical downed memory was located and a solution devised. Memory reintegration proceeded smoothly, enabling the Molimon to bypass one of the downed molly drives.

The system component that most concerned the Molimon reported borderline functional. It sent out a command, to no response. Clearly the trouble was more serious than anyone, including its programmers, had anticipated.

That did not mean the problem was insoluble. It merely required a period of careful internal debate. The Molimon’s internal voting architecture went to work. One processor opted for procedure as written, even though that had already failed. The second suggested an alternative. Noting the failure of the first, processor three sided with two. Having thus analyzed and debated, it tried anew.

This time the door responded. Like all internal airtights it contained its own backup power cell. Running the instructions exhausted the self‑contained cell’s power, but the Molimon was not concerned with that. It wanted the door shut. Opening it again would be a matter for future programs.

Internal alarms began to go off. It had spent entirely too much time operating when it ought to have been shutting down. There was insufficient power to preserve programming. When it shut down now, it would do so with concurrent loss of memory, even though all critical information would be effectively preserved on the surviving mirrored molly drives. The Molimon was not bothered by this knowledge. It had fulfilled another, more important aspect of its programming.

Enough reserve strength remained for it to send a last message to a slave monitor. Composition of the message caused the Molimon some difficulty despite the fact that it had been programmed to accept and respond in plain English.

Then its backup power gave out completely.

Amy was waiting patiently next to the mixing vats when they found her. The jammed lock door gave way with a reluctant groan. Shouts, then laughter, then tears filled the hitherto silent module. She looked very small and vulnerable wrapped up in the dead engineer’s jacket.

Cassie Chin watched the reunion, wiping at her eyes as she listened to the wild exclamations of delight and joy. Mike Macek was tossing his daughter so high into the air, Cassie was afraid that in the limited gravity he was going to bounce her off the ceiling. Her expression turned somber as she watched others kneel beside the body of Morrie Reuschel.

Eventually her attention shifted to the rearmost of the module’s airtight doors. Somehow the Molimon had managed to get it to shut, effectively sealing off the air leak in the section beyond. That action had preserved the remaining atmosphere in the other three‑fourths of the module until the rescue team had succeeded in punching its way in. She regarded the lifesaving door awhile longer, then turned to business.

Karl Hedrickson was waiting for her.

“Look at the damn thing. It’s half bashed in.” He pointed at the debris‑laden floor. “Looks like that big wrench hit it.”

Cassie sighed. “Let’s get the rear panel off.”

Their first view of the Molimon’s guts had Hedrickson shaking his head. “These mollys must’ve gone down first. Then I don’t know what else.”

“But after it fixed itself it figured out how to seal off the leak and stayed online long enough to get the job done.” She shook her head in disbelief. “Batteries?”

Hedrickson ran a quick check, made a face. “Dead as an imploded mouse.”

Chin pursued her lips. “Then the programming’s gone. I don’t mind that except it means we’ll never learn why it didn’t follow accepted procedure and commence preservation shutoff when the primary power went down.”

Hedrickson turned to the nearest monitor, plugged in a power cell, and brought the Molimon unit online. “Nothing here,” he told her after several minutes of inquiry. “No, wait a sec. There is a shutdown indicator. It knew it was going.” He frowned. “The message is in nonstandard format.”

Chin moved to join him. Lights were coming on all around them as repair crews began to restore station power to the hydroponics module.

“What do you mean, it’s ‘nonstandard’?”

Hedrickson ran a speculative finger along the top of the dead Molimon. His voice was flat. “Read it for yourself.”

Chin looked at the softly glowing monitor he was holding. She expected to see the words Shutdown procedure completed.

Instead she saw something else. Something that was, after all, only an indication of programming awareness. Nothing more. What it said was this.

LITTLE GIRLS ARE NOT REDUNDANT.
