The Diamond Age

by Neal Stephenson

  Now Carl had the keys and, for the purposes of the Net, was indistinguishable from Miranda or Nell or Dr. X or even Hackworth himself. They were written out across the surface of a page, long columns of digits grouped in bunches of four. Carl Hollywood told this sheet to fold itself and then tucked it into his breast pocket. He could use them to untangle this whole business, but that would be another night's hack. Snuff and caffeine had done as much as they could. It was time to go back to the hotel, soak in a bath, get some sleep, and prepare for the final act.

  From the Primer, Princess Nell's ride to the Castle

  of King Coyote; description of the castle; an

  audience with a Wizard; her final triumph over

  King Coyote; an enchanted army.

  Princess Nell rode north into an explosive thunderstorm. The horses were driven nearly mad with terror by the cannonlike explosions of the thunder and the unearthly blue flashes of the lightning, but with a firm hand and a soothing voice in the ear, Nell urged them forward. The cairns of bones strewn along the roadside were evidence that this mountain pass was no place to dawdle, and the poor animals would be no less terrified huddling under a rock. For all she knew, the great King Coyote was capable of controlling even the weather itself and had prepared this reception to try Princess Nell's will.

  Finally she crested the pass, and none too soon, as the horses' hooves had begun to slip on a thick layer of ice, and ice had begun thickly to coat the reins and to weigh down the animals' manes and tails. Working her way down the switchbacks, she left the high fury of the storm behind and pushed into masses of rain as dense as any jungle. It was well that she had paused for a few days at the foot of the mountains to review all of Purple's magic books, for on this night ride through the mountains she used every spell Purple had taught her: spells for casting light, for choosing the right fork in the road, for calming animals and warming chilled bodies, for bolstering her own failing courage, for sensing the approach of any monsters foolish enough to venture out in such weather, and for defeating those desperate enough to attack. This night ride was, perhaps, a rash act, but Princess Nell proved equal to the challenge. King Coyote would not expect her to make such a crossing. Tomorrow when the storm on high had cleared, he would send his raven sentinels winging through the pass and down into the plain below to spy on her, as he had for the last several days, and they would return with dismaying news: The Princess had vanished! Even King Coyote's best trackers would not be able to follow her path from yesterday's campsite, so craftily had she covered her real tracks and laid false ones.

  Dawn found her in the heart of a great forest. King Coyote's castle was built on a high woodland plateau surrounded by mountains; she estimated she was several hours' ride away. Staying well clear of the high road taken by the messengers from the Cipherers' Market, she made camp under an overhanging rock along a river, sheltered from the chill wet wind and safe from the eyes of the raven sentinels, and lit a tiny fire where she made some tea and porridge.

  She napped until the middle of the afternoon, then rose, bathed in the bitter water of the stream, and untied the oilcloth packet she had brought with her. It contained one of the costumes worn by the messengers who galloped to and from the Cipherers' Market. It also contained a few books containing enciphered messages—authentic ones dispatched from various stalls in the market addressed to King Coyote's castle.

  As she made her way through the woods toward the high road, she heard massed hoofbeats rolling by and knew that the first contingent of messengers had just come over the pass after waiting for the storm to pass. She waited a few minutes and then followed them. Turning onto the high road out of the dense woods, she reined in her horse and sat for a moment, astonished by her first sight of the Castle of King Coyote.

  She had never seen its like in all of her travels through the Land Beyond. Its base was as wide as a mountain, and its walls rose sheer and straight into the clouds. Galactic clouds of lights shone from its myriad windows. It was guarded by mighty stockades, each of them a great castle unto itself, but built not on stony foundations, but upon the very clouds themselves; for King Coyote, in his cleverness, had devised a way to make buildings that floated on the air.

  Princess Nell spurred her horse forward, for even in her numbness she sensed that someone might be watching the high road from a window high in one of the castle's glittering oriels. As she galloped toward the castle, she was torn between a sense of her own foolishness in daring to assault such a mighty fortress and admiration for King Coyote's work. Faint clouds of diaphanous black oozed between the towers and stockades, and as Princess Nell drew closer, she saw that they were actually regiments of ravens going through their military drills. They were the closest thing King Coyote had to an army; for as one of the ravens had told her, after he had stolen the eleven keys from around her neck,

  Castles, gardens, gold, and jewels

  Contentment signify, for fools

  Like Princess Nell; but those

  Who cultivate their wit

  Like King Coyote and his crows

  Compile their power bit by bit

  And hide it places no one knows.

  King Coyote did not preserve his power by armed might but by cleverness, and sentinels were the only army he needed, information his only weapon.

  As she galloped the final miles to the gate, wondering whether her legs and back would hold out, a thin steam of black issued from a narrow portal high in one of the floating stockades, thickened into a transparent ball, and dove toward her like a plunging comet. She could not help flinching from the illusion of mass and momentum, but, a stone's throw above her head the cloud of ravens parted into several contingents that whirled around and struck from several directions, converging on her, passing around her so closely that the wind from their rattling wings blew her hair back, finally reforming into a disciplined group that returned to its stockade without a look back. Apparently she had passed the inspection. When she reached the mighty gate, it was standing open for her, and no one was guarding it. Princess Nell rode into the broad streets of King Coyote's castle.

  It was the finest place she had ever seen. Here gold and crystal were not hidden away in the King's treasury but were used as building materials. Green and growing things were everywhere, for King Coyote was fascinated by the secrets of nature and had sent his agents to the farthest reaches of the world to bring back exotic seeds. The wide boulevards of King Coyote's city were lined with trees whose arching limbs closed over the ashlars to form a rustling vault. The undersides of the leaves were silver and seemed to cast a gentle light, and the branches were filled with violet and magenta bromeliads the size of kettles, making a sweet sharp smell, aswarm with ruby-throated hummingbirds and filled with water where tiny fluorescent frogs and beetles lived.

  The Messenger's Route was marked with polished brass plates set among the paving-stones. Princess Nell followed it down the grand boulevard, into a park that encircled the city, and then onto a rising street that spiraled around the central promontory. As the horse took her toward the clouds, her ears popped again and again, and from each curve in the road she enjoyed a sweeping view over the lower city and into the constellation of floating stockades where the raven sentinels soared, coming and going in flights and squadrons, bringing news from every corner of the empire.

  She rode by a place where King Coyote was adding on to the castle; but instead of an army of stonemasons and carpenters, the builder was a single man, a portly gray-bearded fellow puffing at a long slender pipe, carrying a leather bag on his belt. Arriving at the center of the building site, he reached into his bag and drew out a great seed the size of an apple and pitched it into the soil. By the time this man had walked back to the spiral road, a tall shaft of gleaming crystal had arisen from the soil and grown far above their heads, gleaming in the sunlight, and branched out like a tree. By the time Princess Nell lost sight of it around the corner, the builder was puffing contentedly and looking at a crystalline vau
lt that nearly covered the lot.

  This and many other wonders Princess Nell saw during her long ride up the spiral road. The clouds cleared away, and Nell found that she could see great distances in every direction. King Coyote's domain was in the very heart of the Land Beyond, and his castle was built on a high plateau in the center of his domain, so that from his windows he could see all the way to the shining ocean in every direction. Nell kept a sharp eye on the horizon as she climbed toward the King's inner keep, hoping she might get a glimpse of the faraway island where Harv languished in the Dark Castle; but there were many islands in the distant sea, and it was hard to tell the Dark Castle's towers from mountain crags.

  Finally the road became level and turned inward to pierce another unguarded gate in another high wall, and Princess Nell found herself in a green, flowery court before the King's keep—a high palace that appeared to have been hewn from a single diamond the size of an iceberg. By now the sun was sinking low in the west, and its orange rays ignited the walls of the keep and cast tiny rainbows everywhere like shards from a shattered crystal bowl. A dozen or so messengers stood in a queue before the doors of the keep. They had left their horses in a corner of the yard where a watering-trough and manger were available. Princess Nell did likewise and joined the queue.

  “I have never had the honor of carrying a message to King Coyote,” Princess Nell said to the messenger preceding her in the queue.

  “It is an experience you will never forget,” said the messenger, a cocky young man with black hair and a goatee.

  “Why must we wait in this queue? In the stalls at the Cipherers' Market, we leave the books on the table and continue on our way.”

  Several of the messengers turned and looked back at Princess Nell disdainfully. The messenger with the goatee made a visible effort to control his amusement and said, “King Coyote is no small-timer sitting in a stall at the Cipherers' Market! This you will soon see for yourself.”

  “But doesn't he make his decisions the same way as all the others—by consulting rules in a book?”

  At this the other messengers made no effort to control their amusement. The one with the goatee took on a distinctly sneering tone. “What would be the point of having a King in that case?” he said. “He does not take his decisions from any book. King Coyote has built a mighty thinking machine, Wizard 0.2, containing all the wisdom in the world. When we bring a book to this place, his acolytes decipher it and consult with Wizard 0.2. Sometimes it takes hours for Wizard to reach its decision. I would advise you to wait respectfully and quietly in the presence of the great machine!”

  “That I will certainly do,” said Princess Nell, amused rather than angered by this lowly messenger's impertinence.

  The queue moved along steadily, and as darkness fell and the orange rays of the sun died away, Princess Nell became aware of colored lights streaming out from within the keep. The lights seemed to be quite brilliant whenever Wizard 0.2 was cogitating and dropped to a low flicker the rest of the time. Princess Nell tried to make out other details of what was going on inside the keep, but the countless facets broke up the light and bent it into all directions so that she could get only hints and fragments; trying to see into King Coyote's inner sanctum was like trying to remember the details of a forgotten dream.

  Finally the messenger with the goatee emerged, gave Princess Nell a final smirk, and reminded her to display proper respect.

  “Next,” intoned the acolyte in a chanting voice, and Princess Nell entered the keep.

  Five acolytes sat in the anteroom, each one at a desk piled high with dusty old books and long reels of paper tape. Nell had brought thirteen books from the Cipherers' Market, and at their direction, she distributed these books among the acolytes for decipherment. The acolytes were neither young nor old but in the middle of their lives, all dressed in white coats decorated, in golden thread, with the crest of King Coyote. Each also had a key around his neck. As Princess Nell waited, they deciphered the contents of the books she had brought and punched the results onto strips of paper tape using little machines built into their tables.

  Then, with great ceremony, the thirteen paper tapes were coiled up and placed on a tremendous silver platter carried by a young altar boy. A pair of large doors was swung open, and the acolytes, the altar boy, and Princess Nell formed into a procession of sorts, which marched into the Chamber of the Wizard, a vast vaulted room, and down its long central aisle.

  At the far end of the chamber was—nothing. A sort of large empty space surrounded by elaborate machinery and clockwork, with a small altar at the front. It reminded Princess Nell of a stage, empty of curtains and scenery. Standing next to the stage was a high priest, older and wearing a more impressive white robe.

  When they reached the head of the aisle, the priest went through a perfunctory ceremony, praising the Wizard's excellent features and asking for its cooperation. As he said these words, lights began to come on and the machinery began to whir. Princess Nell saw that this vault was, in fact, nothing more than an anteroom for a much vaster space within, and that this space was filled with machinery: countless narrow shining rods, scarcely larger than pencil leads, laid in a fine gridwork, sliding back and forth under the impetus of geared power shafts running throughout the place. All of the machinery threw off heat as it ran, and the room was quite warm despite a vigorous draught of cold mountain air being pumped through it by windmill-size fans.

  The priest took the first of the thirteen rolls of paper tape from the platter and fed it into a slot on the top of the altar. At this point, Wizard 0.2 really went into action, and Princess Nell saw that all the whirring and humming she'd seen to this point had been nothing more than a low idle. Each of its million push-rods was tiny, but the force needed to move all of them at once was seismic, and she could sense the tremendous strains on the power shafts and gearboxes thundering through the sturdy floor of the keep.

  Lights came on around the stage, some of them built into the surface of the stage itself and some hidden in the machinery around it. To Princess Nell's surprise, a seemingly three-dimensional shape of light began to coalesce in the center of the empty stage. It gradually formed itself into a head, which took on additional details as the machinery thundered and hissed away: it was an old bald man with a long white beard, his face deeply furrowed in thought. After a few moments, the beard exploded into a flock of white birds and the head turned into a craggy mountain, the white birds swarming about it, and then the mountain erupted in orange lava that gradually filled up the entire volume of the stage until it was a solid glowing cube of orange light. In this fashion did one image merge into another, most astonishingly, for several minutes, and all the time the machinery was screaming away and making Princess Nell most anxious, and she suspected that if she had not seen less sophisticated machines at work at Castle Turing, she might have turned around and fled.

  Finally, though, the images died away, the stage became empty again, and the altar spat out a length of paper tape, which the priest carefully folded up and handed to one of the acolytes. After a brief prayer of thanks, the priest fed the second tape into the altar, and the whole process started up again, this time with different but equally remarkable images.

  So it went with one tape after another. When Princess Nell became accustomed to the noise and vibration of the Wizard, she began to enjoy the images, which seemed quite artistic to her—like something a human would come up with, and not machinelike at all.

  But the Wizard was undoubtedly a machine. She had not yet had the opportunity to study it in detail, but after her experiences in all of King Coyote's other castles, she suspected that it, too, was just another Turing machine.

  Her study of the Cipherers' Market, and particularly of the rule-books used by the cipherers to respond to messages, had taught her that for all its complexity, it too was nothing more than another Turing machine. She had come here to the Castle of King Coyote to see whether the King answered his messages according to Turi
ng-like rules. For if he did, then the entire system—the entire kingdom—the entire Land Beyond—was nothing more than a vast Turing machine. And as she had established when she'd been locked up in the dungeon at Castle Turing, communicating with the mysterious Duke by sending messages on a chain, a Turing machine, no matter how complex, was not human. It had no soul. It could not do what a human did.

  The thirteenth tape was fed into the altar, and the machinery began to whine, then to whir, and then to rumble. The images appearing above the stage flourished into wilder and more exotic forms than any they had seen yet, and watching the faces of the priest and the acolytes, Princess Nell could see that even they were surprised; they had never seen anything of the like before. As the minutes wore on, the images became fragmented and bizarre, mere incarnations of mathematical ideas, and finally the stage went entirely dark except for occasional random flashes of color. The Wizard had worked itself up to such a pitch that all of them felt trapped within the bowels of a mighty machine that could tear them to shreds in a moment. The little altar boy finally broke away and fled down the aisle. Within a minute or so, the acolytes, one by one, did the same, backing slowly away from the Wizard until they were about halfway down the aisle and then turning away and running. Finally even the high priest turned and fled. The rumbling of the machinery had now reached such a pitch that it felt as though an epochal earthquake were in progress, and Nell had to steady herself with a hand on the altar. The heat coming from back in the machine was like that from a forge, and Nell could see a dim red light from deep inside as some of the push-rods became hot enough to glow.
