I can no longer dream in any normal sense. I lack anything that would qualify as a subconscious, and I control all the maintenance functions performed by my brain, so normal REM sleep tasks are obsolete. There are moments when my grasp on my mind slips, but they cannot be called dreams. Meta-hallucinations, perhaps. Sheer torture. These are periods during which I"m detached: I understand how my mind generates the strange visions, but I"m paralyzed and unable to respond. I can scarcely identify what I see; images of bizarre transfinite self-references and modifications that even I find nonsensical.
My mind is taxing the resources of my brain. A biological structure of this size and complexity can just barely sustain a self-knowing psyche. But the self-knowing psyche is also self-regulating, to an extent. I give my mind full use of what"s available, and restrain it from expanding beyond that. But it"s difficult: I"m cramped inside a bamboo cage that doesn"t let me sit down or stand up. If I try to relax, or try to extend myself fully, then agony, madness.
I"m hallucinating. I see my mind imagining possible configurations it could a.s.sume, and then collapsing. I witness my own delusions, my visions of what form my mind might take when I grasp the ultimate gestalts.
Will I achieve ultimate self-awareness? Could I discover the components that make up my own mental gestalts? Would I penetrate racial memory? Would I find innate knowledge of morality? I might determine whether mind could be spontaneously generated from matter, and understand what relates consciousness with the rest of the universe. I might see how to merge subject and object: the zero experience.
Or perhaps I"d find that the mind gestalt cannot be generated, and some sort of intervention is required. Perhaps I would see the soul, the ingredient of consciousness that surpa.s.ses physicality. Proof of G.o.d? I would behold the meaning, the true character of existence.
I would be enlightened. It must be euphoric to experience....
My mind collapses back into a state of sanity. I must keep a tighter rein over my self. When I"m in control at the meta-programming level, my mind is perfectly self-repairing; I could restore myself from states that resemble delusion or amnesia. But if I drift too far on the meta-programming level, my mind might become an unstable structure, and then I would slide into a state beyond mere insanity. I will program my mind to forbid itself from moving beyond its own reprogramming range.
These hallucinations strengthen my resolve to create an artificial brain. Only with such a structure will I be able to actually perceive those gestalts, instead of merely dreaming about them. To achieve enlightenment, I"ll need to exceed another critical ma.s.s in terms of neuronal a.n.a.logs.
I open my eyes: it"s two hours, twenty-eight minutes, and ten seconds since I closed my eyes to rest, though not to sleep. I rise from bed.
I request a listing of my stocks" performance on my terminal. I look down the flatscreen, and freeze.
The screen shouts at me. It tells me that there is another person with an enhanced mind.
Five of my investments have demonstrated losses; they"re not precipitous, but large enough that I"d have detected them in the body language of the stockbrokers. Reading down the alphabetical list, the initial letters of the corporations whose stock values have dropped are: C, E, G, O, and R. Which, when rearranged, spell GRECO.
Someone is sending me a message.
There"s someone else out there like me. There must have been another comatose patient who received a third injection of hormone K. He erased his file from the FDA database before I accessed it, and supplied false input to his doctors" accounts so that they wouldn"t notice. He too stole another ampule of the hormone, contributing to the FDA"s closing of their files, and with his whereabouts unknown to the authorities, he"s reached my level.
He must have recognized me through the investment patterns of my false ident.i.ties; he"d have to have been supercritical to do that. As an enhanced inp cla.s.s="indent"idual, he could have effected sudden and precise changes to trigger my losses, and attract my attention.
I check various data services for stock quotes; the entries on my listing are correct, so my counterpart didn"t simply edit the values for my account alone. He altered the selling patterns of the stock of five unrelated corporations, for the sake of a word. It makes for quite a demonstration; I consider it no mean feat.
Presumably his treatment began before mine did, meaning that he is farther along than I, but by how much? I begin extrapolating his likely progress, and will incorporate new information as I acquire it.
The critical question: Is he friend or foe? Was this merely a good-natured demonstration of his power, or an indication of his intent to ruin me? The amounts I lost were moderate; does this indicate concern for me, or for the corporations which he had to manipulate? Given all the harmless ways he could have attracted my attention, I must a.s.sume that he is to some degree hostile.
In which case, I am at risk, vulnerable to anything from another prank to a fatal attack. As a precaution, I will leave immediately. Obviously, if he were actively hostile, I"d be dead already. His sending a message means that he wishes us to play games. I"ll have to place myself on equal terms with him: hide my location, determine his ident.i.ty, and then attempt to communicate.
I pick a city at random: Memphis. I switch off the flatscreen, get dressed, pack a travel bag, and collect all the emergency cash in the apartment.
In a Memphis hotel, I begin working at the suite"s datanet terminal. The first thing I do is reroute my activities through several dummy terminals; to an ordinary police trace, my queries will appear to originate from different terminals all over the state of Utah. A military intelligence facility might be able to track them to a terminal in Houston; continuing the trace to Memphis would try even me. An alarm program at the Houston terminal will alert me if someone has successfully traced me there.
How many clues to his ident.i.ty has my twin erased? Lacking all FDA files, I"ll begin with the files of courier services in various cities, looking for deliveries from the FDA to hospitals during the time of the hormone K study. Then a check of the hospital"s brain-damage cases at that time, and I"ll have a place to start.
Even if any of this information remains, it"s of minor value. What will be crucial is an examination of the investment patterns, to find the traces of an enhanced mind. This will take time.
His name is Reynolds. He"s originally from Phoenix, and his early progress closely parallels mine. He received his third injection six months and four days ago, giving him a head start over me of fifteen days. He didn"t erase any of the obvious records. He waits for me to find him. I estimate that he"s been supercritical for twelve days, twice as long as I"ve been.
I now see his hand in the investment patterns, but the task of locating Reynolds is Herculean. I examine usage logs across the datanet to identify the accounts he"s penetrated. I have twelve lines open on my terminal. I"m using two single-hand keyboards and a throat mike, so I can work on three queries simultaneously. Most of my body is immobile; to prevent fatigue, I"m ensuring proper blood flow, regular muscle contraction and relaxation, and removal of lactic acid. While I absorb all the data I see, studying the melody within the notes, looking for the epicenter of a tremor in the web.
Hours pa.s.s. We both scan gigabytes of data, circling each other.
His location is Philadelphia. He waits for me to arrive.
I"m riding in a mud-splattered taxi to Reynolds"s apartment.
Judging by the databases and agencies Reynolds has queried over the past months, his private research involves bioengineered microorganisms for toxic waste disposal, inertial containment for practical fusion, and subliminal dissemination of information through societies of various structures. He plans to save the world, to protect it from itself. And his opinion of me is therefore unfavorable.
I"ve shown no interest in the affairs of the external world, and made no investigations for aiding the normals. Neither of us will be able to convert the other. I view the world as incidental to my aims, while he cannot allow someone with enhanced intelligence to work purely in self-interest. My plans for mind-computer links will have enormous repercussions for the world, provoking government or popular reactions that would interfere with his plans. As I am proverbially not part of the solution, I am part of the problem.
If we were members of a society of enhanced minds, the nature of human interaction would be of a different order. But in this society, we have unavoidably become juggernauts, by whose measure the actions of normals are inconsequential. Even if we were twelve thousand miles apart we couldn"t ignore each other. A resolution is necessary.
Both of us have dispensed with several rounds of games. There are a thousand ways we could have attempted to kill the other, from painting neurotoxin-laced DMSO on a doork.n.o.b to ordering a surgical strike from a military killsat. We both could have swept the physical area and datanet for each of the myriad possibilities beforehand, and set more traps for each other"s sweeps. But neither of us has done any of that, has felt a need to check for those things. A simple infinite regression of second-guessing and double-thinking has dismissed those. What will be decisive are those preparations that we could not predict.
The taxi stops; I pay the driver and walk up to the apartment building. The electric lock on the door opens for me. I take off my coat and climb four flights.
The door to Reynolds" apartment is also open. I walk down the entryway to the living room, hearing a hyperaccelerated polyphony from a digital synthesizer. Evidently it"s his own work; the sounds are modulated in ways undetectable to normal hearing, and even I can"t discern any pattern to them. An experiment in high-information-density music, perhaps.
There is a large swivel chair in the room, its back turned toward me. Reynolds is not visible, and he is restricting his somatic emanations to comatose levels. I imply my presence and my recognition of his ident.i.ty.
Acknowledgment. The chair turns around smoothly, slowly. He smiles at me and shuts off the synthesizer at his side. Gratification. True, acting cooperatively would produce achievements far outstripping any we might attain inp cla.s.s="indent"idually. Any interaction would be incredibly fruitful: how satisfying it would be simply to have a discussion with someone who can match my speed, who can offer an idea that is new to me, who can hear the same melodies I do. He desires the same. It pains us both to think that one of us will not leave this room alive.An offer. He knows what my answer is.We will speak aloud, since somatic language has no technical vocabulary. Reynolds says, quickly and quietly, five words. They are more pregnant with meaning than any stanza of poetry: each word provides a logical toehold I can mount after extracting everything implicit in the preceding ones. Together they encapsulate a revolutionary insight into sociology; using somatic language he indicates that it was among the first he ever achieved. I came to a similar realization, but formulated it differently. I immediately counter with seven words, four that summarize the distinctions between my insight and his, and three that describe a non.o.bvious result of the distinctions. He responds.
We continue. We are like two bards, each cueing the other to extemporize another stanza, jointly composing an epic poem of knowledge. Within moments we accelerate, talking over each other"s words but hearing every nuance, until we are absorbing, concluding, and responding, continuously, simultaneously, synergistically.
Many minutes pa.s.s. I learn much from him, and he from me. It"s exhilarating, to be suddenly awash in ideas whose implications would take me days to consider fully. But we"re also gathering strategic information: I infer the extent of his unspoken knowledge, compare it with my own, and simulate his corresponding inferences. For there is always the awareness that this must come to an end; the formulation of our exchanges renders ideological differences luminously clear.
Reynolds hasn"t witnessed the beauty that I have; he"s stood before lovely insights, oblivious to them. The sole gestalt that inspires him is the one I ignored: that of the planetary society, of the biosphere. I am a lover of beauty, he of humanity. Each feels that the other has ignored great opportunities.
He has an unmentioned plan for establishing a global network of influence, to create world prosperity. To execute it, he"ll employ a number of people, some of whom he"ll give simple heightened intelligence, some meta-self-awareness; a few of them will pose threats to him. I can measure the distance between our respective moral stances precisely, see the stress between their incompatible radiating lines. What motivates him is not simply compa.s.sion or altruism, but something that entails both those things. On the other hand, I concentrate only on understanding the sublime. He considers intelligence to be a means, while I view it as an end in itself. Greater intelligence would be of little use to him. At his present level, he can find the best possible solution to any problem within the realm of human experience, and many beyond. All he"d require is sufficient time to implement his solution.There"s no point in further discussion. By mutual a.s.sent, we begin.
It"s meaningless to speak of an element of surprise when we time our attacks; our awareness can"t become more acute with forewarning. It"s not affording a courtesy to each other when we agree to begin our battle, it"s actualizing the inevitable.
In the models of each other that we"ve constructed from our inferences, there are gaps, lacunae: the internal psychological developments and discoveries that each has made. No echoes have radiated from those s.p.a.ces, no strands have tied them to the world web, until now.
I begin.
I concentrate on initiating two reinforcing loops in him. One is very simple: it increases blood pressure rapidly and enormously. If it were to continue unchecked for over a second, this loop would raise his blood pressure to stroke levels- perhaps 400 over 300- and burst capillaries in his brain.
Reynolds detects it immediately. Though it"s clear from our conversation that he never investigated the inducement of biofeedback loops in others, he recognizes what is happening. Once he does, he reduces his heart rate and dilates the blood vessels throughout his body.
But it is the other, subtler reinforcing loop that is my real attack. This is a weapon I"ve been developing ever since my search for Reynolds began. This loop causes his neurons to dramatically overproduce neurotransmitter antagonists, preventing impulses from crossing his synapses, shutting down brain activity. I"ve been radiating this loop at a much higher intensity than the other.
As Reynolds is parrying the ostensible attack, he experiences a slight weakening of his concentration, masked by the effects of the heightened blood pressure. A second later, his body begins to amplify the effect on its own. Reynolds is shocked to feel his thoughts blurring. He searches for the precise mechanism: he"ll identify it soon, but he won"t be able to scrutinize it for long.
Once his brain function has been reduced to the level of a normal, I should be able to manipulate his mind easily. Hypnotic techniques can make him regurgitate most of the information his enhanced mind possesses.
I inspect his somatic expressions, watching them betray his diminishing intelligence. The regression is unmistakable.
And then it stops.
Reynolds is in equilibrium. I"m stunned. He was able to break the reinforcing loop. He has stopped the most sophisticated offensive I could mount.
Next, he reverses the damage already done. Even starting with reduced capabilities, he can correct the balance of neurotransmitters. Within seconds, Reynolds is fully restored.
I too was transparent to him. During our conversation he deduced that I had investigated reinforcing loops, and as we communicated, he derived a general preventative without my detecting it. Then he observed the specifics of my particular attack while it was working, and learned how to reverse its effects. I am astonished at his discernment, his speed, his stealth.
He acknowledges my skill.
A possibility I antic.i.p.ated. I reformulate my psyche, incorporating random elements for unpredictability. The equations of my mind now bear little resemblance to those of my normal consciousness, undermining any a.s.sumptions Reynolds may have made, and rendering ineffectual any psyche-specific weapons of his.
I project the equivalent of a smile.
Reynolds smiles back. Suddenly he projects only silence. He is about to speak, but I can"t predict what. Then it comes, as a whisper: "self-destruct commands, Greco?"As he says it, a lacuna in my reconstruction of him fills and overflows, the implications coloring all that I know about him. He means the Word: the sentence that, when uttered, would destroy the mind of the listener. Reynolds is claiming that the myth is true, that every mind has such a trigger built in; that for every person, there is a sentence that can reduce him to an idiot, a lunatic, a catatonic. And he is claiming he knows the one for me.
I immediately tune out all sensory input, directing it to an insulated buffer of short-term memory. Then I conceive a simulator of my own consciousness to receive the input and absorb it at reduced speed. As a metaprogrammer I will monitor the equations of the simulation indirectly. Only after the sensory information has been confirmed as safe will I actually receive it. If the simulator is destroyed, my consciousness should be isolated, and I"ll retrace the inp cla.s.s="indent"idual steps leading to the crash and derive guidelines for reprogramming my psyche.
I get everything in place by the time Reynolds has finished saying my name; his next sentence could be the destruct command. I"m now receiving my sensory input with a one-hundredand-twenty-millisecond time lag. I reexamine my a.n.a.lysis of the human mind, explicitly searching for evidence to verify his a.s.sertion.
Meanwhile I give my response lightly, casually. My search produces something. I curse myself: there"s a very subtle back door to a psyche"s design, which I lacked the necessary mind-set to notice. Whereas my weapon was one born of introspection, his is something only a manipulator could originate.Reynolds knows that I"ve built my defenses; is his trigger command designed to circ.u.mvent them? I continue deriving the nature of the trigger command"s actions.
He"s confident that additional time won"t allow me to construct a defense. So smug. Can he actually toy with me so easily?I arrive at a theoretical description of a trigger"s effects on normals. A single command can reduce any subcritical mind to a tabula rasa, but an undetermined degree of customization is needed for enhanced minds. The erasure has distinctive symptoms, which my simulator can alert me to, but those are symptoms of a process calculable by me. By definition the destruct command is that specific equation beyond my ability to imagine; would my metaprogrammer collapse while diagnosing the simulator"s condition?
I begin calculating what"s needed to generate a customized destruct command. It becomes obvious that the generation is a colossal task. Generating a trigger requires intimate knowledge of my mind; I extrapolate what he could have learned about me. It appears to be insufficient, given my reprogramming, but he may have techniques of observation unknown to me. I"m acutely aware of the advantage he"s gained by studying the outside world. His regret is evident. His plan can"t be implemented without more deaths: those of normal humans, by strategic necessity, and those of a few enhanced a.s.sistants of his, whose temptation by greater heights would interfere. After using the command, Reynolds may reprogram them- or me- as savants, having focused intentions and restricted self-metaprogrammers. Such deaths are a necessary cost of his plan. Merely a savior.
Normals might think him a tyrant, because they mistake him for one of them, and they"ve never trusted their own judgment. They can"t fathom that Reynolds is equal to the task. His judgment is optimal in questions of their affairs, and their notions of greed and ambition do not apply to an enhanced mind.
In a histrionic gesture, Reynolds raises his hand, forefinger extended, as if to make a point. I don"t have sufficient information to generate his destruct command, so for the moment I can only attend to defense. If I can survive his attack, I may have time to launch another one of my own.
With his finger upraised, he says, "Understand."
At first I don"t. And then, horrifyingly, I do.
He didn"t design the command to be spoken; it"s not a sensory trigger at all. It"s a memory trigger: the command is made out of a string of perceptions, inp cla.s.s="indent"idually harmless, that he planted in my brain like time bombs. The mental structures that were formed as a result of those memories are now resolving into a pattern, forming a gestalt that defines my dissolution. I"m intuiting the Word myself.
Immediately my mind is working faster than ever before. Against my will, a lethal realization is suggesting itself to me. I"m trying to halt the a.s.sociations, but these memories can"t be suppressed. The process occurs inexorably, as a consequence of my awareness, and like a man falling from a height, I"m forced to watch.
Milliseconds pa.s.s. My death pa.s.ses before my eyes.
An image of the grocery store when Reynolds pa.s.sed by. The psychedelic shirt the boy was wearing; Reynolds had programmed the display to implant a suggestion within me, ensuring that my "randomly" reprogrammed psyche remained receptive. Even then.
No time. All I can do is metaprogram myself over randomly, at a furious pace. An act of desperation, possibly crippling.
The strange modulated sounds that I heard when I first entered Reynolds" apartment. I absorbed the fatal insights before I had any defenses raised.
I tear apart my psyche, but still the conclusion grows clearer, the resolution sharper.
Myself, constructing the simulator. Designing those defense structures gave me the perspective needed to recognize the gestalt.
I concede his greater ingenuity. It bodes well for his endeavor. Pragmatism avails a savior far more than aestheticism.
I wonder what he intends to do after he"s saved the world.
I comprehend the Word, and the means by which it operates, and so I dissolve.
Division by Zero
1.
Dividing a number by zero doesn"t produce an infinitely large number as an answer. The reason is that division is defined as the inverse of multiplication: if you divide by zero, and then multiply by zero, you should regain the number you started with. However, multiplying infinity by zero produces only zero, not any other number. There is nothing which can be multiplied by zero to produce a nonzero result; therefore, the result of a division by zero is literally "undefined."
