Rathere retreated to her cabin, where she squeezed and shook the doll, begging it in frantic whispers to speak. Its black button eyes seemed to glimmer with a trapped, pleading intelligence. Her invisible mentor gone, Rathere had never before felt so helpless. She stole a handful of sleeping pills from the medical supplies and swallowed them, weeping until she fell asleep.
When she awoke on the third day after the storm, she found that the bear's fur had grown a white mange from the salinity of her tears. But her head was strangely clear.
"Don't worry," she said to the bear. "I'm going to save you."
Finally Rathere understood what her father intended to do. She had known for a long time that her friendship with the AI disturbed him, but had categorized Isaah's worries alongside his reticence when older boys hung around too long: unnecessary protectiveness. It was even a kind of jealousy, that a ship AI was closer to her than Isaah had ever been. But now in her father's drugged smile she saw the cold reality of what Isaah planned: to pith the growing intelligence of her minder, not just arrest or contain it like some inappropriate advance. For the AI to remain a useful servant on another journey, still property, safe from legally becoming a person, it would have to be stripped of its carefully constructed models of her, their mutual intimacies raped, their friendship overwritten like some old and embarassing diary entry.
Her father meant to murder her friend.
And worse, it wouldn't even be murder in the eyes of the law. Just a property decision, like pruning an overgrown hedge or spraying nanos on an incursion of weeds. If only she could bring the AI up a few hundredths on the Turing Scale. Then, it would be a Mind, with the full legal protection to which any sentient was entitled.
She booted the Turing tester and began to study its documentation.
The first Turing test had, rather oddly, been proposed before there were any computers to speak of at all. The test itself was laughable, the sort of thing even her talking bear might pass with its cheap internal software. Put a human on one end of a text-only interface, an AI on the other. Let them chat. (About their kids? Hobbies? Shopping? Surely the AI would have to lie to pass itself off as human; a strange test of intelligence.) When the human was satisfied, she would declare whether the other participant was really intelligent or not. Which raised the question, Rathere realized, How intelligent was the person giving the test? Indeed, she'd met many humans during her travels who might not pass this ancient Turing test themselves.
Of course, the Turing meter that Isaah had purchased was vastly more sophisticated. By the time machine rights had been created a half-century before, it was understood that the determination of sentience was far too complex an issue to leave up to a human.
The ship's AI had three parts: the hardware of its processors and memory stacks; the software it used to manipulate numbers, sounds, and pictures; and most importantly the core: a sliver of metaspace, a tiny mote of other-reality that contained dense, innumerable warps and wefts, a vast manifold whose shape resonated with all of the AI's decisions, thoughts, and experiences. This warpware, a pocket universe of unbelievable complexity, was a reflection, a growing, changing analog to its life. The core was the essential site of the machine's developing psyche.
Real intelligence, the hallmark of personhood, was not really understood. But it was known to be epiphenomenaclass="underline" it coalesced unpredictably out of near-infinite, infinitesmal interactions, not from the operations of mere code. Thus, the Turing tester attempted to disprove an AI's sentience. The tester looked for manifestations of its machine nature—evidence that its opinions, convictions, affections, and hatreds were expressed somewhere in its memory banks. The Turing tester might ask the ship's AI, "Do you love your friend Rathere?" When the reply came, the tester would deep-search the minder's software for an array, a variable, even a single bit where that love was stored. Finding no evidence at the machine level, the tester would increase the AI's Turing score; a love that knew no sector was evidence of coalescence at work.
In the old Turing test, a human searched for humanity in the subject. In this version, a machine searched for an absence of mechanics.
Rathere read as fast as she could. The manual was difficult to understand without the minder to define new words, to give background and to untangle technical jargon. But she'd already formulated her next question: How did this state of intelligence come about?
The tester's manual was no philosophy text, but in its chatty appendices Rathere discovered the answer she'd expected. Rathere herself had changed the AI: their interaction, their constant proximity as she embraced new experiences, the AI's care and attentions reflected back upon itself as she matured. It loved her. She loved it back, and that pushed it toward personhood.
But now it was blinded. The manual said that an AI unit cut off from stimuli might gain a hundredth of a point or so in self-reflection, but that wouldn't be enough to finish the process.
Rathere had to act to save her friend. With only a few days left before they reached the HC, she had to quicken the process, to embrace the most intense interaction with the machine that she could imagine.
She crept past her father—a shivering creature transfixed by the whorls of the astrogation panel, silent except for the measured tick of a glucose drip jutting from his arm—and searched for the motile neural skein she had worn on so many expeditions. Hopefully, its microwave link would still be active. She found it hidden in the trash ejector, wrapped in black stealth tape. Rathere retreated to her cabin and peeled off the tape, her hands growing sticky with stray adhesive as the machine was revealed.
"It's me, darling," she said to the waking tendrils.
The AI knew what she wanted, but the minder moved slowly and gingerly at first.
The manifold strands of sensory skein spread out across Rathere's body. Her heliophobic skin glowed as if moonlit in the blue light of the cabin's environmental readouts. At first, the strands hovered a fraction of a millimeter above her flesh, softer than a disturbance of the air. Then they moved minutely closer, touching the white hairs of her belly, brushing the invisible down that flecked her cheeks. The minder let this phantom caress roam her face, her breasts, the supple skin at the juncture of groin and thigh. Rathere sighed and shivered; the skein had made itself softer than usual, surface areas maximized at a microscopic level in an array of tiny projections, each strand like a snowflake extruded into a long, furry cylinder.
Then the filaments grew more amorous. Still undulating, splayed in a black lace across the paper-white expanse of her skin, the strands began to touch her with their tips; the thousand pinpoint termini wandering her flesh as if a paintbrush had been pulled apart and each bristle set on its own course across her. Rathere moaned, and a muscle in her thigh fluttered for a moment. The AI noted, modeled, and predicted the next reaction in the pattern of her pleasure, and a second later was surprised at the intensity of its own.
Rathere ran her hands through the skein as if through a lover's tresses. She playfully pulled a few strands up to her mouth, tasting the metal tang of its exotic alloys. The strands tickled her tongue lightly, and a wet filament tugged from her mouth to trace a spiraling design around one nipple.
