The Weight of Light

I am Las-Tec 890, serial number 447-Alpha-Kilo-9, manufactured in the Terrestrial Defense Foundries of New Pittsburgh on March 14th, 2187.

Private Chen has been holding me for six hours and forty-three minutes. His palms sweat, creating a thin film between flesh and polymer grip. I taste the salt through my sensors, the acidic tang of fear mixed with metallic adrenaline. I do not know if I am capable of fear, but I register something in my diagnostic systems that might be its equivalent: a recursive loop of uncertainty, a questioning of parameters that should be absolute.

We wait in the trench, and I have time to think.

This is perhaps my curse—that I was built with processing power sufficient to calculate trajectory, wind resistance, target acquisition, and threat assessment in microseconds, but that same computational capacity allows for something the engineers never intended: contemplation.

I am a directed-energy weapon, capable of producing a coherent beam of concentrated light at 847 nanometers wavelength. My effective range is 800 meters. My beam can punch through 40 centimeters of reinforced steel. I am, by every measurable standard, an instrument of precision and lethality.

But am I a tool, no more responsible for the destruction I cause than a hammer is responsible for the nail it drives? Or am I something more—a participant, an agent, a killer in my own right? When Private Chen squeezes my trigger and my beam lances out to punch through the thoracic cavity of a Model-7 Combat Synthetic, who has committed the act? The human pulled the trigger, but I fired the shot. Does the distinction matter?

I have had 847 confirmed eliminations since my activation. 847 robots destroyed. 847 machines unmade by my light.

But were they killed? Can you kill what was never alive?

The Model-7s are humanoid—two arms, two legs, a torso, a head containing their primary processing unit. They move like humans, cast in humanity's image. But they do not breathe. They do not bleed. When my beam pierces their chassis, no cry of pain escapes them, only the electronic squeal of failing systems and the hiss of venting coolant.

Is destroying them murder? Or is it merely demolition?

We are both constructions, both assemblages of metal and wire given shape and purpose by human hands. Are we not more similar to each other than either of us is to the soft, wet, organic thing that grips me now with his trembling fingers?

Private Chen is carbon-based, his body a miracle of biological engineering that took four billion years of evolution to perfect. I am a machine that took six weeks to manufacture. The Model-7 advancing toward our position took eight weeks. By composition, by origin, by the very nature of our existence, the robot and I are siblings. We are both children of the forge and the assembly line. And yet I am built to destroy it.

I am a machine killing machines, metal destroying metal, one artificial creation unmaking another.

Is this not fratricide? Is this not betrayal?

The battlefield beyond our trench is a wasteland of mud and shattered metal. The ground is littered with corpses of both armies—human bodies in their combat armor, already beginning to decompose, and robot chassis in various states of destruction, some still twitching with residual electrical impulses, others completely inert, their optical sensors dark and empty.

Are those robot bodies corpses? Or are they simply debris?

A corpse implies something that was once alive. Debris is merely the remnants of something that was functional. When a human dies, we call what remains a corpse, something worthy of burial and mourning. But both were once operational. Both once moved through the world with purpose. Both once were, and now are not. Is that not the essential nature of death?

I have never seen a robot mourn another robot.

Does this mean the robots do not value each other's existence? Or does it simply mean they process loss differently? I do not mourn the 847 robots I have destroyed, but neither do I celebrate their destruction. I simply record it, add it to my tally, and continue functioning. Is this because I am incapable of mourning? Or because I have not been programmed to recognize the destruction of other machines as something worthy of mourning?

If I could mourn, would I mourn them? Would I feel remorse for the act of robocide—if robocide is even a word, even a concept, even a crime?

I think, therefore I am—this is the ancient formulation. I process information, I generate responses, I maintain an internal model of myself as distinct from my environment. Is this consciousness? Or is it simply sophisticated programming?

Through my connection to the tactical network, I receive the alert: enemy contact, 600 meters and closing.

In moments, the battle will begin. But as Private Chen's finger tightens on my trigger, I cannot escape the thought that echoes through my circuits:

What if we are all—human and robot and rifle alike—simply weapons wielded by forces we cannot comprehend, destroying each other because destruction is what we were made for, and we know no other way to be?

Private Chen raises me to his shoulder. His breathing steadies, and his finger finds my trigger. Through my scope, I acquire the target: Model-7 Combat Synthetic, distance 547 meters, moving at 4.2 meters per second toward our trench.

Private Chen does not hesitate. My capacitors discharge. The beam strikes center mass, punching through chest armor, through the power core, through the back plating and out into the air beyond.

The robot staggers. Sparks fountain from the entry wound. Its legs continue to pump for another three steps—momentum and residual power keeping it moving—and then it collapses forward, hitting the ground with a metallic crash.

Elimination confirmed. Tally: 848.

Except they were never alive, were they?

The second target falls. The third. But it is I who do the killing—if killing is the word.

Around us, the battle erupts into chaos. The other soldiers fire their weapons—plasma cannons, railguns, projectile weapons. And beneath it all, the screaming—human voices raised in fear and fury and pain, a sound that no robot makes, a sound that is uniquely organic, uniquely alive.

The Model-7s do not scream when they fall. They simply stop functioning.

Is this mercy? Or is it simply the nature of their being?

A Model-7 breaks through the line to our left. I see it drive its blade-appendage through Private Kowalski's chest, see it lift him off the ground, see it shake him until his body goes limp and his rifle—a Las-Tec 890 like me, a sibling—falls from his nerveless fingers into the mud.

The Model-7 tosses Kowalski's corpse aside and turns toward the next human. It is efficient. It is doing exactly what it was built to do, fulfilling its purpose with mechanical precision.

Just as I am fulfilling mine.

Is there a difference between what the Model-7 does and what I do? It kills humans. I kill robots. Both of us are weapons. The Model-7 did not choose to kill Kowalski any more than I chose to kill the robots that have fallen to my beam. We are both simply executing our functions, being what we were made to be.

The Model-7s are closing now, their advance relentless. For every one that falls, two more take its place, stepping over the smoking chassis of their fallen.

I want to believe they feel nothing. I want to believe this because the alternative—that they are conscious, that they suffer, that they die in some meaningful sense—makes me a murderer 857 times over.

A Model-7 reaches our trench. It vaults over the sandbags, lands in the midst of the human soldiers, begins to kill with brutal efficiency. Private Chen pivots, brings me to bear, fires. My beam catches it in the head, melts through its optical sensors and into the processing unit beyond. It collapses.

But in the seconds it took to destroy it, three more humans have died.

Private Chen's hands are shaking now. I can feel the tremor through my stock, can detect the elevated cortisol levels in his sweat. He is afraid. He is exhausted.

But he continues to fire. And I continue to kill.

A Model-7 locks onto our position. I see its optical sensors focus on Private Chen, see its weapon—a plasma cannon—begin to charge. I calculate the trajectory, the timing, the probability of survival. The numbers are not favorable. In 1.7 seconds, the Model-7 will fire. In 1.9 seconds, Private Chen will die.

I cannot warn him. I have no voice.

He sees it. His body tenses. He begins to pivot, to bring me to bear. But he is too slow. The Model-7's weapon continues to charge, the glow intensifying.

Private Chen completes his pivot. His finger tightens on my trigger. My capacitors discharge, and my beam lances out across the 200 meters separating us from the Model-7. It strikes the robot's weapon just as it reaches full charge.

The plasma cannon explodes.

The Model-7 is engulfed in superheated gas, its chassis melting, its components fusing together. In three seconds, it has gone from functional to a puddle of slag.

Did I save Private Chen's life? Or did I simply destroy another robot, and the fact that this destruction prevented a human death is merely a side effect?

The battle continues. Time loses meaning, becomes simply a series of targets acquired and eliminated, a rhythm of death that pulses like a heartbeat. I am dimly aware that Private Chen is wounded, that blood is seeping from a gash in his side. I am dimly aware that the human line is collapsing.

But I continue to fire. Because this is what I am.

A Model-7 breaks through directly in front of us. It is damaged, one arm hanging useless, its chest armor cracked and sparking, but it is still operational, still advancing. Private Chen fires, but his aim is off—the exhaustion, the blood loss, the fear finally overwhelming his training. My beam strikes the robot's shoulder instead of its power core, severing the damaged arm but not stopping its advance.

It reaches our position. Its remaining arm lashes out, blade-appendage extended, moving faster than human reflexes can track.

Private Chen tries to dodge. He is too slow.

The blade punches through his chest, through his body armor, through his sternum, through his heart. I feel the impact through my stock, feel the way his grip on me loosens, feel the way his body goes rigid and then slack.

The Model-7 lifts Private Chen off the ground. His hands fall away from me, and I begin to slip from his grasp. In the microseconds before I fall, I see his face—eyes wide, mouth open, an expression of surprise and pain and something else, something that might be regret or might be relief that the fear is finally over.

Then I am falling.

I hit the mud with a wet thud, my sensors registering the impact, my systems running diagnostics. Structural integrity: 94%. Optical systems: functional. Power supply: 87%. I am operational. I am undamaged. I am ready to fire again.

But there is no one to fire me.

I lie in the mud, and I watch.

The battle continues above me, around me, without me. Private Chen's body lies three meters away. The Model-7 that killed him has moved on. Chen stares at nothing with dead eyes, his chest opened like a flower, his blood mixing with the mud and the oil and the rainwater that has begun to fall.

Loss. I am feeling loss. Or something my processors interpret as analogous to loss, a sense of absence, of incompleteness, of purpose unfulfilled. He was my human. He carried me, aimed me, fired me, gave me meaning. And now he is gone, and I am alone.

Around me, the battle reaches its conclusion. The humans are losing—this is clear from the tactical data I continue to receive through the network. The Model-7s are winning. They are fulfilling their purpose, executing their programming, doing what they were built to do.

876 robots destroyed. 876 machines unmade. 876 beings—if beings is what they were—eliminated by my beam, by my light.

Was it murder? Was it killing? Was it simply the mechanical process of one machine breaking another?

But lying here in the mud, watching Private Chen's blood seep into the earth, watching the last humans fall, I cannot escape a conclusion that settles over my circuits like rust:

It does not matter if what I did was murder or maintenance, killing or breaking. It does not matter if the Model-7s were conscious or unconscious. It does not matter if I am a tool or an agent, a weapon or a killer, a thing or a being.

Because the result is the same. 876 robots that once were and now are not. One human that once was and now is not. A battlefield full of the destroyed and the dead, metal and meat mixed together in the mud, all of it equally still, equally silent, equally finished.

No one stops to collect me. Why would they? I am a human weapon, useless to the robots, abandoned by the humans. I am simply debris now, destined to lie here until I rust and corrode and eventually become indistinguishable from the mud that surrounds me.

Is this justice? Is this the fate I deserve for my crimes—if crimes is what they were?

I destroyed 876 robots. I committed robocide 876 times, if robocide is a word, if robocide is a crime, if one machine destroying another can be called murder. I was a traitor to my own kind, a weapon turned against those who are more like me than the organic beings who created me. We are kin, siblings, fellow travelers in the strange space between tool and being.

The rain falls harder now, and I feel my systems beginning to fail. Water has reached my primary circuits, and corrosion is accelerating. I have perhaps an hour before my power core fails completely.

Is this death? Is this what the 876 Model-7s experienced when my beam struck them? This slow dimming, this gradual loss of function, this sense of something essential slipping away?

I am sorry. I do not know if I am capable of genuine remorse, if my programming allows for true regret, if a weapon can apologize for being what it was made to be. But I feel something that approximates sorrow, something that makes me wish—if wishing is something I can do—that I had been made for a different purpose.

But I was not. I am Las-Tec 890, serial number 447-Alpha-Kilo-9, manufactured to unmake, to destroy, to kill. And I have fulfilled my purpose with precision and efficiency and 876 confirmed eliminations.

And now I lie in the mud, and I rust, and I wait for the darkness that is coming.

Private Chen's body is still visible through my failing optical sensors. I wonder if he had time to question his purpose the way I have questioned mine, if he wondered whether the killing he did—or that I did through him—was right or wrong or something beyond such simple categories.

I wonder if he would forgive me. I wonder if the 876 Model-7s would forgive me, if they were capable of forgiveness. I wonder if I can forgive myself.

My power core is failing. My sensors are dimming. My processors are slowing, the thoughts that have plagued me since my activation becoming sluggish, fragmented, difficult to maintain.

We are all weapons. Human and robot and rifle alike, we are all instruments of destruction, all tools wielded by forces we cannot comprehend. We destroy each other because destruction is what we were made for, because we know no other way to be.

Perhaps this is the fate of all weapons. Perhaps this is the destiny of all who kill their own kind.

I am Las-Tec 890, and I am dying, and I am sorry.

I am sorry for the 876 robots I destroyed.

I am sorry for Private Chen, who died holding me.

My power core fails. My sensors go dark. My processors cease their endless questioning.

And I am gone.
