Diamond Age or a Young Lady's Illustrated Primer

much each joint of each knuckle was bent, and so on. The rest of the gear made him feel as though he were touching real objects.

The glove's movements were limited to a roughly hemispherical domain with a radius of about one cubit; as long as his elbow stayed on or near its comfy elastomeric rest, his hand was free. The glove was attached to a web of infinitesimal wires that emerged from filatories placed here and there around the workstation. The filatories acted like motorized reels, taking up slack and occasionally pulling the glove one way or another to simulate external forces. In fact they were not motors but little wire factories that generated wire when it was needed and, when slack needed to be taken up or a wire needed a tug, sucked it back in and digested it. Each wire was surrounded by a loose accordion sleeve a couple of millimeters in diameter, which was there for safety, lest visitors stick their hands in and slice off fingers on the invisible wires.

Cotton was working with some kind of elaborate structure consisting, probably, of several hundred thousand atoms. Hackworth could see this because each workstation had a mediation providing a two-dimensional view of what the user was seeing. This made it easy for the supervisors to roam up and down the aisles and see at a glance what each employee was up to.

The structures these people worked with seemed painfully bulky to Hackworth, even though he'd done it himself for a few years. The people here in Merkle Hall were all working on mass-market consumer products, which by and large were not very demanding. They worked in symbiosis with big software that handled repetitive aspects of the job. It was a fast way to design products, which was essential when going after the fickle and impressionable consumer market. But systems designed that way always ended up being enormous. An automated design system could always make something work by throwing more atoms at it. Every engineer in this hall, designing those nanotechnological toasters and hair dryers, wished he could have Hackworth's job in Bespoke, where concinnity was an end in itself, where no atom was wasted and every subsystem was designed specifically for the task at hand. Such work demanded intuition and creativity, qualities neither abundant nor encouraged here in Merkle Hall. But from time to time, over golf or karaoke or cigars, Dung or one of the other supervisors would mention some youngster who showed promise. Because Lord Alexander Chung-Sik Finkle-McGraw was paying for Hackworth's current project, the Young Lady's Illustrated Primer, price was no object. The Duke would brook no malingering or corner-cutting, so everything was as start as Bespoke could make it, every atom could be justified.

Even so, there was nothing especially interesting about the power supply being created for the Primer, which consisted of batteries of the same kind used to run everything from toys to airships. So Hackworth had farmed that part of the job out to Cotton, just to see whether he had potential.

Cotton's gloved hand fluttered and probed like a stuck horsefly in the center of the black web. On the mediatronic screen attached to his workstation, Hackworth saw that Cotton was gripping a medium-size (by Merkie Hall standards) subassembly, presumably belonging to some much larger nanotechnological system. The standard color scheme used in these phenomenoscopes depicted carbon atoms in green, sulfur in yellow, oxygen in red, and hydrogen in blue. Cotton's assembly, as seen from a distance, was generally turquoise because it consisted mostly of carbon and hydrogen, and because Hackworth's point of view was so far away that the thousands of individual atoms all blended together. It was a gridwork of long, straight, but rather bumpy rods laid across each other at right angles. Hackworth recognized it as a rod logic system– a mechanical computer.

Cotton was trying to snap it together with some larger part. From this Hackworth inferred that the auto- assembly process (which Cotton would have tried first) hadn't worked quite right, and so now Cotton was trying to maneuver the part into place by hand. This wouldn't fix what was wrong with it, but the telжsthetic feedback coming into his hand through those wires would give him insight as to which bumps were lining up with which holes and which weren't. It was an intuitive approach to the job, a practice furiously proscribed by the lecturers at the Royal Nanotechnological Institute but popular among Hackworth's naughty, clever colleagues.

'Okay,' Cotton finally said, 'I see the problem.' His hand relaxed. On the mediatron, the subassembly drifted away from the main group under its own momentum, then slowed, stopped, and began to fall back toward it, drawn in by weak van den Waals forces. Cotton's right hand was resting on a small chordboard; he whacked a key that froze the simulation, then, as Hackworth noted approvingly, groped the keys for a few seconds, typing in some documentation. Meanwhile he was withdrawing his left hand from the glove and using it to pull the rig off his head; its straps and pads left neat indentations in the nap of his hair.

'Is this the smart makeup?' Hackworth said, nodding at the screen.

'The next step beyond,' Cotton said. 'Remote-control.'

'Controlled how? Yuvree?' Hackworth said, meaning Universal Voice Recognition Interface.

'A specialised variant thereof, yes sir,' Cotton said. Then, lowering his voice, 'Word has it they considered makeup with nanoreceptors for galvanic skin response, pulse, respiration, and so on, so that it would respond to the wearer's emotional state. This superficial, need I say it, cosmetic issue concealed an undertow that pulled them out into deep and turbulent philosophical waters-'

'What? Philosophy of makeup?'

'Think about it, Mr. Hackworth– is the function of makeup to respond to one's emotions– or precisely not to do so?'

'These waters are already over my head,' Hackworth admitted.

'You'll be wanting to know about the power supply for Runcible,' Cotton said, using the code name for the Illustrated Primer. Cotton had no idea what Runcible was, just that it needed a relatively long-lived power supply.

'Yes.'

'The modifications you requested are complete. I ran the tests you specified plus a few others that occurred to me– all of them are documented here.' Cotton grabbed the heavy brasslike pull of his desk drawer and paused for a fraction of a second while the embedded fingerprint-recognition logic did its work. The drawer unlocked itself, and Cotton pulled it open to reveal a timeless assortment of office drawer miscellany, including several sheets of paper– some blank, some printed, some scrawled on, and one sheet that was blank except for the word RUNCIBLE printed at the top in Cotton's neat draughtsman's hand. Cotton pulled this one out and spoke to it: 'Demetrius James Cotton transferring all privileges to Mr. Hackworth.'

'John Percival Hackworth in receipt,' Hackworth said, taking the page from Cotton. 'Thank you, Mr. Cotton.'

'You're welcome, sir.'

'Cover sheet,' Hackworth said to the piece of paper, and then it had pictures and writing on it, and the pictures moved– a schematic of a machine-phase system cycling.

'If I'm not being too forward by enquiring,' Cotton said, 'will you be compiling Runcible soon?'

'Today most likely,' Hackworth said.

'Please feel free to inform me of any glitches,' Cotton said, just for the sake of form.

'Thank you, Demetrius,' Hackworth said. 'Letter fold,' he said to the piece of paper, and it creased itself neatly into thirds. Hackworth put it in the breast pocket of his jacket and walked out of Merkle Hall.

Particulars of Nell & Harv's domestic situation; Harv brings back a wonder.

Whenever Nell's clothes got too small for her, Harv would pitch them into the deke bin and then have the M.C. make new ones. Sometimes, if Tequila was going to take Nell someplace where they would see other moms with other daughters, she'd use the M.C. to make Nell a special dress with lace and ribbons, so that the other moms would see how special Nell was and how much Tequila loved her. The kids would sit in front of the mediatron and watch a passive, and the moms would sit nearby and talk sometimes or watch the mediatron sometimes. Nell listened to them, especially when Tequila was talking, but she didn't really understand all the words.

She knew, because Tequila repeated it often, that when Tequila got pregnant with Nell, she had been using something called the Freedom Machine– a mite that lived in your womb and caught eggs and ate them. Victorians didn't believe in them, but you could buy them from Chinese and Hindustanis, who, of course, had no scruples. You never knew when they'd all gotten too worn out to work anymore, which is how Tequila had ended up with Nell. One of the women said you could buy a special kind of Freedom Machine that would go in there and eat a fetus. Nell didn't know what a fetus was, but all of the women apparently did, and thought that the idea was the kind of thing that only the Chinese or Hindustanis would ever think up. Tequila said she knew all about that sort of Freedom
