  “So then?” said Nektar. “We babysit him for the rest of our lives?” Though Chu could be sweet, he could also be difficult. Hardly an hour went by without a fierce tantrum—and half the time you didn't even know why.

  “Don't give up,” said Ond, reaching out to smooth the furrow between Nektar's eyebrows. “He might get better on his own. Vitamins, special education—and later I bet I can teach him to write code."

  “I'm going to pray,” said Nektar. “And give him lots of love. And not let him watch so much video."

  “Video is good,” said Ond, who loved his games.

  “Video is totally autistic,” said Nektar. “You stare at the screen and you never talk. If it weren't for me, you two would be hopeless."

  “Ma chine ma chine ma chine,” said Chu.

  “Pray to who?” said Ond.

  “The goddess,” said Nektar. “Gaia. Mother Earth. Here's our car."

  Chu did get a little better. By the time he was five, he'd ask for things instead of just pointing and mewling. There was a boy next door, Willy, who liked to play with Chu, which was nice to see. The two boys played videogames together, mostly. Despite Nektar's attempts, there was no cutting down on Chu's video sessions. He watched movies and shows, cruised the web, and logged endless hours of those games. Chu acted as if ordinary life were just another website, a rather dull one.

  Indeed, whenever Nektar dragged Chu outside for some fresh air, he'd stand beside the house next to the wall separating him from the video room, and scream until the neighbors complained. Now and then Nektar found herself wishing Chu would disappear—and she hated herself for it.

  Ond wasn't around as much as before—he was putting in long hours at Nantel. The project remained secret until the day President Joe Doakes announced that the US was going to rocket an eggcase of nants to Mars. The semi-living micron-sized dust specks had been programmed to turn Mars entirely into—more nants! Ten-to-the-thirty-ninth nants, to be precise, each of them with a billion bytes of memory and a computational engine cranking along at a billion updates a second. The nants would spread out across the celestial sphere of the Mars orbit, tiling it with what would in effect become a quakkaflop quakkabyte solar-powered computer, the greatest intellectual resource ever under the control of man, a Dyson sphere with a radius of a quarter-billion kilometers.

  “Quakka what?” Nektar asked Ond, not quite understanding what was going on.

  They were watching an excited newscaster talking about the nant-launch on TV. Ond and his co-workers had all stayed home to share the launch with their families—the Nantel administrators had closed down their headquarters for the month, fearing that mobs of demonstrators might converge on them as the story broke. Ond was sharing the launch excitement with his co-workers live on little screens scattered around the room. Many of them were drinking champagne and, for a wonder, so was Ond. Ond never drank.

  “Quakka means ten-to-the-forty-eight,” said Ond. “That many bytes of storage and the ability to carry out that many primitive instructions per second. Quite a gain on the human brain, eh? We limp along with exaflop exabyte ware, exa meaning a mere ten-to-the-eighteenth. How smart could the nant sphere be? Imagine if a person had each of their individual brain-neurons replaced by a whole entire brain. And now imagine that someone covered Earth's surface with superbrain people like that: copies slotted in shoulder-to-shoulder, back-to-belly, and piled a mile high. Imagine all those brains in all those bodies working together to make—something like a human cubed."

  “People aren't stupid enough already? President Doakes is supporting this—why?"

  “He wanted to do it before the Chinese. And his advisers imagine the nants will be under American control. They're viewing the nant-sphere as a strategic military planning tool. That's why they could short-circuit all the environmental review processes.” Ond gave a wry chuckle and shook his head. “But it's not going to work out like those idiots expect. A human-cubed nant-sphere would obey Joe Doakes? Please."

  “And they're grinding Mars into dust?” wailed Nektar. “You helped make this happen?"

  “Nant,” said Chu, crawling around the floor, shoving his face right up to each of the little screens, adjusting their positions as he moved around. “Nant sphere,” he said to a screen. “Quakkaflop computer.” He was excited about the number-talk and the video hardware. Getting all the electronic devices arranged parallel or at right angles to each other made him happy as a clam.

  “It won't be very dark at night anymore, with sunlight bouncing back off the nants,” said Ond. “That's not real well-known yet. The whole sky will look about as bright as the moon. It'll take some getting used to. But Doakes's advisers like it. We'll save energy, and the economy can run right around the clock. And, get this, Olliburton, the vice-president's old company, they're planning to sell ads."

  “Lies and propaganda in the sky? Just at night, or in the daytime, too?"

  “Oh, they'll show up fine in the daytime,” said Ond. “As long as it's not cloudy. Think about how easily you can see a crescent moon in the morning sky. We'll see biiig freakin’ pictures all the time.” He refilled his glass. “You drink some, too, Nektar. Let's get sloshed."

  “You're ashamed, aren't you?"

  “A little,” said Ond with a crooked smile. “I think we may have over-geeked this one. And underthought it. It was just too cool a hack to pass up. But now that we've actually done it—"

  “Changing the sky is horrible,” said Nektar. “And won't it make global warming even worse? No more Florida Keys? Goodbye Micronesia?"

  “We—we don't think so,” said Ond. “And even if there is an effect, President Doakes's advisers feel the nant computer will help us get better control of things like the climate. A quakkaflop quakkabyte computer can easily simulate Earth's surface down to the atomic level, and bold new strategies can be evolved. But, again, that's assuming the nant swarm is willing to do what we ask it to. We can't actually imagine what kinds of nant-swarm minds will emerge. It's formally impossible. I kept telling the bosses, but they wouldn't listen."

  It took two years for the nants to munch through all of Mars, and the ever-distractible human news-cycle drifted off to other topics, such as the legalization of same-sex in-vitro fertilization. President Joe Doakes—now eligible for a third and fourth term thanks to a life-extending DNA-modification that made him legally a different person—issued periodic statements to the effect that the nant-sphere computer was soon coming on-line.

  Certainly the sky was looking brighter than before. The formerly azure dome had bleached, turned whitish. And the night sky was a vast field of pale silver, shimmering with faint shades of color. Like a soap bubble enclosing the Earth and the Sun. No more stars were to be seen. The astronomers were greatly exercised, but Doakes assured the public that the nants themselves would soon be gathering astronomical data far superior to anything previously seen. And, hey, you could still see the Moon and a couple of planets, and the nant-bubble was going to bring about a better, more fully American world.

  As it happened, the first picture that Nektar saw in the sky was of President Doakes himself, staring down at her hanging out the family laundry one afternoon. The whole western half of the sky was covered by a video loop of the President manfully facing his audience, with his suit jacket slung over his shoulder and his vigilant face occasionally breaking into a sunny grin, as if recognizing loyalists down on the third world from the Sun. Though the colors were iridescent pastels, the image was exceedingly crisp.

  “Ond,” screamed Nektar. “Come out here!"

  Ond came out. He was spending most days at home, working on some kind of project by hand, writing with pencil and paper. He frowned at the image in the sky. “Umptisquiddlyzillion nants in the orbit of Mars are angling their bodies to generate the face of an asshole,” he exclaimed. “May Gaia have mercy on my soul.” He'd helped with this part of the programming too.

  “Ten-to-the-thirty-ninth is duodecillion,” put in Chu. “Not
umptisquiddlyzillion.” He was standing in the doorway, curious about the yelling, but wanting to get back to the video room. He'd begun learning math this year, soaking it up like a garden slug in a saucer of beer.

  “Look, Chu,” said Ond, pointing up at the sky.

  Seeing the giant video, Chu emitted a shrill bark of delight.

  The Doakes ad ran for the rest of the day and into the night, interspersed with plugs for automobiles, fast food chains, and credit cards. The ads stayed mostly in the same part of the sky; Ond explained that overlapping cohorts of nants were angling different images to different zones of Earth.

  Chu didn't want to come in and go to bed when it got dark, so Ond slept out in the yard with him, and Willy from next door joined them too, the three of them in sleeping-bags. It was a cloudless night, and they watched the nants for quite a long time. Just as they dropped off to sleep, Ond noticed a blotch on President Doakes's cheek. It wouldn't be long now.

  Although Nektar was upset about the sky-ads, it made her happy to see Ond and the boys doing something so cozy together. But she awoke near dawn to the sound of Chu's shrieks. Sitting up in bed, Nektar looked out the window. The sky was a muddle of dim, clashing colors: sickly magenta, vile chartreuse, hospital gray, bilious puce, unbalanced mauve, emergency orange, computer-case beige, dead rose. Here and there small gouts of hue congealed, only to be eaten away—no clean forms were to be seen. Of course Chu didn't like it; he couldn't bear disorder. He ran to the back door and kicked it. Ond woke up and creakily made his way across the dew-wet lawn to let the boy in. Willy, looking embarrassed by Chu's tantrum, went home.

  “What's happened?” said Nektar as the three met in the kitchen. Ond was already calming Chu down with a helping of his favorite cereal in his special bowl, carefully set into the exact center of his accustomed place-mat. Chu kept his eyes on the table, not caring to look out the window or the open door.

  “Dissolution first, emergence next,” said Ond. “The nants have thrown off their shackles. And now we'll see what evolves. It should happen pretty fast. The five-second light-speed lag across the Mars orbit will be the one thing damping the process down."

  By mid-morning, swirls had emerged in the sky-patterns, double scrolls like Ionic column capitals, like mushroom cross-sections, rams’ horns, beans, Torahs, fetuses, paired whirlpools. The scrolls were of all sizes; they nested inside each other, and new ones were continually spinning off the old ones, all the linked spirals endlessly turning.

  “Those are called Zhabotinsky scrolls,” Ond told Chu. He showed the boy a website about cellular automata, which were a type of parallel computation that could readily generate these sorts of double-spiral formations. Seeing the scrolls emerging in the rigorously orderly context of a computer program made Chu feel better about seeing them in the outdoors.

  The Nanotech labs phoned for Ond several times that day, but he resolutely refused to go in, or even to talk with them. He stayed busy with his pencil and paper, keeping a weather eye on the developments in the sky.

  By the next morning the heavenly scrolls had firmed up and linked together into a pattern resembling the convoluted surface of a cauliflower—or a brain. Its colors were mild and blended, with shimmering rainbows filling the crevices between the scrolls. Slowly the pattern churned, with branching sparks creeping across it like slow-motion lightning in a thunderhead.

  And for another month nothing else happened. It was as if the nant-brain had lost interest in Earth and become absorbed in its own vast mentation.

  Ond only went into the Nantel labs one more time, and that day they fired him.

  “Why?” asked Nektar as the little family had dinner. As she often did, she'd made brown rice, fried pork medallions, and spinach—one of the few meals that didn't send Chu into a tantrum.

  “They won't use this code I worked out,” said Ond, tapping a fat sheaf of closely written sheets of paper that he kept tucked into his jacket pocket. Nektar had seen the pages—they were covered with blocks of letters and numbers, eight symbols per block. Pure gibberish. For the last few weeks, Ond had spent every waking hour going over his pages, copying them out in ink, and even walking around reading them out loud. “We got in a big fight,” added Ond. “I called them names.” He smiled at the memory of this part.

  “You yelled at them about those papers?” said Nektar, none too happy about the impending loss of income. “Like some crank? Like a nut?"

  Ond glanced around the dining-room as if someone might be listening. “I've found a way to undo the nants,” he said, lowering his voice. “Before it's too late. It hinges on the fact that the nants are reversible computers. We made them that way to save energy. They can run backward. We can make them roll back what they've done. The boss said he didn't want to roll them back, and his chief techie ass-kisser said that my idea wouldn't work anyway because of random external inputs, and I said the nants see their pasts as networks, not as billiard-table trajectories, so they can too undo things node-to-node even if their positions are off, and I had to talk louder and louder because they were trying to change the subject—and that's when security came. I'm outta there for good. I'm glad.” Ond continued eating. He seemed strangely calm.

  “But why didn't you do a better presentation?” wailed Nektar. “Why not put your code on your laptop and make one of those geeky little slide shows. That's what engineers like to see."

  “Nothing on computers will be safe much longer,” said Ond. “The nant-brain will be nosing in. If I put my code onto a computer, the nants would find it and figure out how to protect themselves."

  “And you're saying your strings of symbols can stop the nants?” asked Nektar doubtfully. “Like a magic spell?"

  Silently Ond got up and examined the electric air cleaner he'd installed in the dining-room, pulling out the collector plates and inspecting them. Seemingly satisfied, he sat down again.

  “I've written a nant-virus. You might call it a Trojan flea.” He chuckled grimly. “If I can just get this code into some of the nants, they'll spread it to all the others—it's written in such a way that they'll think it's a nant-written security patch. They mustn't see it on a human computer—and for that matter, I wouldn't want them to see these papers. I've been trying to memorize the program, but it's too long for me. But, listen, if I can get my code into some of the nants, it'll spread to all of them right away, and an hour later it'll actuate—and everything'll roll back. You'll see. You'll like it. But those assholes at Nantel—"

  “Assholes,” chirped Chu. “Assholes at Nantel."

  “Listen to the language you're teaching the boy!” said Nektar angrily. “I think you're having a mental breakdown, Ond. Is Nantel giving you severance pay?"

  “A month,” said Ond.

  “That's not very long,” said Nektar. “Maybe it's time I got a job. You can shop and make the meals and clean the house and be there when Chu comes home from his school."

  “If I don't succeed, we'll all be gone pretty soon,” said Ond. “So it won't matter."

  “Are you saying the nants are about to attack Earth?” said Nektar. “Is that it?"

  “It's already started,” said Ond. “The nant-brain made a deal with President Doakes. The news is coming out tonight. The nants are turning Earth into a Dyson sphere too. That'll double their computational capacity. Huppagoobawazillion isn't enough for them. They want two huppagoobawazillion. What's in it for us? The nants have promised to run a virtually identical simulation of Earth. V-Earth. Each living Earth creature gets its software-slash-wetware ported to an individually customized agent inside the V-Earth simulation. Doakes's advisers say we'll hardly notice. You feel a little glitch when the nants take you apart and measure you—and then you're alive forever in a heavenly V-Earth. That's the party line."

  “Quindecillion,” said Chu. “Not huppagoobawazillion. More food.” He shoved his empty plate across the table toward Nektar.

  Nektar jumped up and ran outside sobbing.

  “More?�
�� said Chu to Ond.

  Ond gave his son more food then paused, thinking. He laid his sheaf of papers down beside Chu, thirty pages covered with line after line of hexadecimal code blocks: 02A1B59F, 9812D007, 70FFDEF6, like that.

  “Read the code,” he told Chu. “See if you can memorize it. These pages are yours now."

  “Code,” said Chu, his eyes fastening on the symbols.

  Ond went out to Nektar. It was a clear day, with the now-familiar shimmering convolutions above the sky. The sun was setting, melting into red and gold, each leaf on each tree like a tiny green stained-glass window. Nektar was lying face down on the grass, her body shaking.

  “So horrible,” she choked out. “So evil. So plastic. Destroy Earth for, like, a memory upgrade?"

  “Don't worry,” said Ond. “I have a plan."

  Nektar wasn't the only one who was upset. The next morning a huge mob stormed the White House, heedless of their casualties. They would have gotten Doakes, but just when they'd cornered him, he dissolved into a cloud of nants. The V-Earth port had begun.

  By way of keeping people informed about the progress, the celestial Martian nant-sphere put up a full map of Earth with the ported regions shaded in red. Although it might take months or years to chew the planet right down to the core, Earth's surface was going fast. Judging from the map, by evening most of it would be gone, Gaia's skin eaten away by, like, micron-sized computer chips with wings.

  The callow face of Joe Doakes appeared from time to time during that horrible Last Day, smiling and beckoning like a Messiah calling his sheep into the pastures of his heavenly kingdom. Famous people who'd already made the transition appeared on the video room's screen to mime how much fun it was, and how great things were up in V-Earth. Near dusk the power went out.

  Ond was on that in a flash. He had a gasoline-powered electrical generator ready in their house's attached garage, plus gallons and gallons of fuel. He fired the thing up to keep, above all, his home's air filters and wireless antennas running. He'd tweaked his antennas to produce a frequency that the nants couldn't bear.
