  Glancing at the Chinese representative, Gerald felt pretty sure that Ramesh was at least somewhat off-target. Still, Haihong Ming kept silent, enigmatically impassive, content to let Ramesh talk on.

  “Hence the reason why so many people find all the tumult and disarray among the Artifact beings … reassuring. Perhaps even endearing. It implies that no person or group out there is enforcing rigid uniformity. We’ll be free to pick and choose from a wide variety of role models, negotiate among partners and competitors, and retain much of what we value about our own past.

  “And yes, I, too, feel encouraged by all that.”

  Only then Ramesh frowned, his complexion darkening.

  “But our colleague from the People’s Ministry of Science does not take consolation so easily, does he? And Emily is even more dourly suspicious! So, let me guess the reasoning. You two think that all of this adorable bustle and crowding and alien-elbowing-alien may be a ruse? That it may be faked, in order to lull us?”

  Haihong Ming nodded. “I am merely trying to cover the full range of possibilities, Dr. Trivedi. All the purported representatives that we have seen, from dozens of different extraterrestrial races—they could be faked. Mere cartoon puppets that always vanish before we can examine them too closely. Suppose the effect were intentional. That they were all contrived by a single entity, with a single agenda. Not only to stall and put off inconvenient questions—but also in order to give us an impression of lively, raucous but peaceful diversity? The very thing that might mollify and comfort many of us?”

  Many of us … but not all of us, Gerald thought. His mouth half opened to point this out, then closed again. His every instinct shouted that the aliens really were separate beings, eagerly diverse and rather fractious, with their own agendas and purposes, scraping against each other within the context of their compact universe. But then … my human instincts might be the very thing that a supersophisticated alien AI could swiftly learn to play upon. The same way that a skilled dramavid team might draw in millions of viewers, getting them to hypnotically believe in artificial characters of the latest full-immersion miniseries.

  At least we’re advanced enough to ponder all these possibilities. But what if other stones fell to Earth, long ago? How might they have dazzled our ancestors?

  Gerald’s specs had been tracking his gaze and iris fluctuations, temporal lobe surges, and subvocal comments half sent to his larynx. All of that—plus the surrounding conversation—fed a steady churn of googs and guesses about what might interest him, constantly re-prioritized so that only the most plausible would float into his periphery of vision … while leaving Gerald free to focus on real people and events, straight ahead. Done right, associative attention assistance simply imitated the way creative folk already thought—making millions of connections, while only a few reached surface awareness. Gerald had never been able to afford the best intelligence enhancement aiware … till now. Until price suddenly became no object.

  Now, he was still getting used to the souped-up gear. One corner of his specs lit up in a yellow, high-pri shade, indicating that a virt was coming in, from a person of substance with top credibility scores. From someone in the Advisory Panel … eighty or so experts who were permitted to watch the commission deliberate in real time, and offer suggestions.

  Gerald first saw it gist-distilled down to a single phrase—“many may be one, and vice-versa.” But, in less than a second the glimmer expanded, filling out the meaning and acquiring a vaice, especially as first Akana, then Genady, clicked approval.

  “The distinction between ‘one’ and ‘many’ can be ambiguous. The best models of a human mind portray it as a mélange of interests and subpersonalities, sometimes in conflict, often merging, overlapping, or recomposing with agile adaptability.

  “Sanity is viewed as a matter of getting these fluid portions of the self to play well together, without letting them become rigid or too well defined. In human beings, this is best achieved through interaction with other minds—other people—beyond the self. Without the push-back of external beings—outside communities and objective events—the subjective self can get lost in solipsism or fractured delusion.

  “We know from experience that solitude or sensory deprivation can be especially devastating. Prisoners who are kept in sequestered confinement often wind up dividing their minds into explicit personas—rigid characters that grow firm and permanent, with consistent voices all their own. Perhaps they do this in order to have someone to talk to.

  “Now extrapolate this. Picture a ‘person’ who has lived alone, as isolated as any castaway, for untold centuries. Even eons. All of it endured without any external beings to converse with. Just floating in space, lacking actual events to help mark time or to denote real from imagined.

  “Is it possible that you or I, after such extended loneliness, might envision, then believe in, separate personalities? Characters who started out as imaginary figments, but gradually became as varied and interesting and diverse as you might find in a whole world—or in a community of worlds? Interacting with each other in ways that reflect the disorder and pain of a long, harsh state of isolation?”

  Emily gasped. “I hadn’t thought of that. But the implication … you’re saying the Artifact may not be making up these characters in order to fool us.

  “Instead, it might be doing so because it is insane!”

  “I did not use that term. In fact, there is another word that comes to mind. More optimistic and less judgmental, it could also explain the ‘Rabble Effect’—the chaotic jumble of personalities and images.

  “Instead of malignant intent, or insanity, the sheer diversity of alien types that we see may reflect simple wishfulness, on the part of a lonesome mind. One that was originally designed as an emissary. One built to yearn for contact.”

  Gerald saw it coming. He spoke aloud, before the advisory voice could state the obvious.

  “You think the Artifact is asleep. That it may be dreaming.

  “In which case, can we—or should we—try to wake it up?”

  * * *

  Tiger sifted all the different theories into a multidimensional matrix, performed some optimization simulations, and came up with a suggestion.

  “I propose that we try operant conditioning.”

  The phrase sounded familiar to Gerald. His wetbrain memory tickled—possibly something he had learned in freshman biology class. But why bother reaching for it neuronally? Definitions scrolled under the quasi-feline face, sparking associations. Ah, yes. B. F. Skinner and his famous pigeons. Using reward and punishment to reinforce some behaviors while eliminating others. Anyone who ever trained a dog knew the basics.

  “We should stop providing information, and even very much in the way of illumination to power the Artifact, except when the creatures within decide to settle down, behave less manically competitive, and start talking with us in a cogent manner.”

  “Forcing them to get organized and stop behaving like unsupervised kindergartners.” Akana nodded with approval. It seemed that the idea of teaching aliens discipline appealed to her.

  “And what of those other possibilities?” Emily asked, pointing at the plausibility matrix. “One theory suggests that the Rabble Effect may be a pretense. The appearance of an unruly mob may be feigned, as if by actors, playing roles. All this wild diversity could be made-up by a single mind. One that’s nefarious, or crazy … or perhaps dreaming?”

  “Well,” answered the feline-female visage in the threevee tank. “This plan would seem best, in any event. It would show that we mean business. That it is time to rouse and get focused. To stop any pretense.”

  Gerald stared. All the experts insisted that ersatz personae like Tiger weren’t truly self-aware or sapient—only programmed to seem that way. But when did the distinction become absurd, even foolish?

  Ramesh shook his head. “They … it … the Artifact already knows a lot about us. If we try such a ploy, it may simply call our bluff, betting that we
can’t hold out for long. Not with several billion people watching and the potential of rich treasures to be gained from contact. Demands from the public—and our political masters—will put a time limit on any such experiment. And this thing has plenty of experience with patience.

  “Still,” he shrugged, “it does seem to be the best idea on the table.”

  When it came to a vote, Gerald raised his hand in assent. Still, he kept one thought to himself—

  —that operant conditioning can work both ways. Sometimes, the one who thinks he’s doing the training … may be the one being trained.

  PIONEERS

  Okay, it’s me Slawek again. Promoted from tour guide to reclam leader. Yeah, I’m just a kid. So? If you don’t like taking directions from a fourteen-year-old deepee, just go to the Duty Desk and ask Dariga Sadybekova to assign you to another team. Or tell Dr. Betsby your troubles, if he’ll listen. Oh yes … he’s out of town!

  Look, I don’t care if you just arrived from Outer Slobovia, or if your biofeedback guru wants you to buzz-meditate twelve hours a day, or if you still have the Awfulday Twitches. Everybody works. That’s a rule if you want to keep living here under the Silverdome.

  In fact, some of the work parties are dorma-fun. Hunting pheasant and picking wild grapes in the wild suburbs, or sledge-demoling abandoned houses and stripping their last traces of metal. Pounding down the walls in search of hidden treasures.

  Sorry, we’re not doing that today.

  We’ll be sewer-diving under one of the Detroit reclamation neighborhoods we Silverdomers were granted, as a homestead domain by the state of Michigan. That is, if we can improve it.

  Yeah, okay. Sewer work. So? Why blink? Almost nobody lives there, so there won’t be much flushing going on. And we all get micropore masks. So it shouldn’t stink. Much.

  One reason for this pre-briefing is to make you familiar with the task and a crude map of what’s down there. Our job is to install RFID repeater-chips every half meter along all the pipes and mains we can reach, so this part of the underworld can join the World Mesh. Currently, it’s way dark down there! And with no link it’s possible to get lost. Really lost! So remember the buddy system.

  We must keep a good pace, ’cause another crew will be right behind us, staple-gluing data strand to the roof of the sewer. A startup company wants to compete with cable and phone conduit providers. They aim to use sewage rights-of-way to deliver fiber cable to every toilet—I mean, every home—in America. (A far-raki idea! I’m already invested.)

  Finally, each of you will be given a siphon bottle and a sack. We’ll show you how to find low spots in the sewer that may have collected pools of mercury, across the last century or two. Suck those little deposits into the bottle. The bag is in case you spot saltpeter crystals along the way. Or coins. There are a dozen other treasures to look out for—one more reason to pay attention to this briefing.

  Phos prices are up and you can trade whatever you find for zep rides or driz, when we get back to our big dome-home.

  THE AVENUE WITHIN

  The shunt caused a strange kind of agony. The worst since the zeppelin explosion left her body a roasted shell.

  Even the word itself felt painful, in a way, because it was misleading. Like other journalists of a new generation, Tor disliked the mushy inexactitude of earlier correspondents—their propensity for oversimplification and loosey-juicy metaphor. To be precise then, the “shunt” that doctors and technicians were installing into her brain was not a single tube or wire. It consisted of more than ten thousand separate pathways that started out as tiny holes, drilled into her skull.

  From there, minuscule, trail-blazing automatons probed inward, proceeding cautiously. Minimizing damage to fragile axons, dendrites, and neural clusters, where calcium ions surged and electro-chemical potentials flared, all contributing to the vast standing wave of composite human consciousness. Skirting all of that, as much as possible, the microscopic machines instead navigated their way inward via giant astrocyte cells, using them as fatty corridors, while each little crawler tugged a slender fiber behind it, until the final destination—some well-mapped center of communication, vision, or motor control—lay just ahead.

  Tor appreciated the lack of pain receptors inside a human brain. Or so assured the doctors, in tinny voices that crackled down the remnants of her auditory system—those portions that had not been seared away by the zeppelin explosion. In fact, the creeping nano-robots should not trigger any conspicuous reaction at all, as they made their way to preplanned positions in the visual cortex, the cerebellum, the anterior cingulate, the left temporal lobe … and a host of other crucial nexi, scattered through Tor’s intricately folded cerebrum. That is, not until they were ready to start their real work—probing and testing, mapping old connections and creating new ones that might—possibly—let her see again, and hear and speak after a fashion.

  And perhaps … science willing … even move and walk and …

  But it seemed better not to dwell too much on hope. So instead, Tor clinically envisioned what was going on inside her head. Imagination perceived the machine incursion as a benign army of penetrating needles—or invading mites—crawling inexorably inward, forcing their way past all barriers of decency, into a sanctum that had once been ultimately private. Or, as private as anything could be, in this modern world.

  Then, upon arriving at its destined station, each little robot began poking! Jabbing and zapping the tips of selected dendrites, sometimes achieving nothing, or else triggering instantaneous reactions—a speck of “light” … a twinge of her left big toe … the smell of roasted pine nuts … a sudden hankering to see, once again, her girlhood pet retriever, Daffy.

  Reacting with disorientation, even nausea, Tor soon felt warm countercurrents flow—undoubtedly drugs meant to keep her body calm and mind alert—as the doctors began to make demands upon her, asking about each sensorimotor effect.

  Irritated by their yattering, for a brief time she considered withholding cooperation. But that impulse didn’t last. As if they would let me refuse. Anyway, to do so—in order to tell them off—Tor would have to speak, to make her wishes understood by some means other than tooth-taps in Morse code. Till then, she would be ruled incompetent, a ward of the state and of her company’s insurance plan, lacking any legal right to make them all bug off!

  So, Tor clicked her canines and bicuspids, in order to answer simple questions—such as identifying “left” and “right,” “up” and “down,” when bright smudges began to appear, triggered by probes that stimulated different parts of her visual cortex. And soon, what had started as gross blobs began resolving into ever smaller pixel-like points, or slender rays, or slanting bars that crossed from one side to another … as some computer gradually learned the cipher of her own, unique way of seeing.

  Everyone’s different, I hear. Our inner images map onto the same reality as other people see—the same streetlights and billboards and such. Each of us claims to perceive identical surroundings. We all call the sky “blue.” And yet, the actual experience of sight—the “qualia”—is said to be peculiar to each person. Our brains are not logically planned. They evolve—every one of us, in that sense, becoming her own species.

  Tor realized she was reciting, as if for her vraudience! Parsing clear sentences, even though there was—so far—no subvocal transceiver to convey her words around the world. Or even across the room. It seemed that habit, sometimes a dear friend, was drawing her back into the role of reporter and raconteur. And, even without a public to appreciate it—she still deemed it good, a source of pleasure and pride, to shape rounded sentences. To describe what was happening—that offered her a glimmering sense of power, amid utter powerlessness.

  Part of me survived, whole. Maybe the best part.

  Not that Tor was ever entirely alone. There were the human specialists and computer-voiced aidviser programs hired by MediaCorp to take care of their superstar. And, ensuring that she neve
r felt abandoned in the darkness, there was the voice of the mob—the smart-mob she had called up, aboard the Spirit of Chula Vista. It never left her side … though individual members came and went. Whenever the hospital allowed it, during frequent breaks and visitor hours, that composite voice returned to keep Tor company, to read to her, or else keep her up with current events.

  What would I have done, if there had been deeper brain damage? she wondered. Injury that prevented the reception and “hearing” of auditory input, for example? The voices in her head kept her sane. They were her link to the real world.

  And so, between medical sessions, when her tooth ached from tapping a million yes and no answers—helping identify the scattered and minute segments of her rebuilding brain—she was also fed a steady description of each day’s news. Naturally, that included the planetary fascination with a stone from interstellar space—the Livingstone Object. But there were also reports on a hard-pressed search for the zeppelin saboteurs. Those who murdered poor Warren and left her in this state, encased in a life-sustaining cocoon.

  Tor’s direct recollections of that episode were a bit murky—trauma often prevented the firm anchoring of memories of some shattering event. She did remember Warren as a set of clipped impressions … along with images of a cathedral filled with tall, colored columns that bulged and throbbed menacingly. No doubt, some of it was just a visual reconstruction, based on things she had been told—about her own valorous actions.

  In fact, the earliest clear image to take shape within her visual cortex—the first one consisting of more than simple geometric forms—rippled and finally resolved into a wavering headline from the top-ranked MediaCorp virpaper, The Guardian. It showed a grainy, wavering, animated image that had to be a zeppelin, wounded, with a gaping, burned area smoldering along its top. A battered ship, but still proud and eager for the sky. Below, one could make out specks that were evidently passengers, spilling down escape slides and dispersing to safety.
