Accelerando

'But my aunt is -' Amber's eyes cross as she concentrates. Annette is already waiting, as it happens, and a shared secret appears in Amber's awareness almost before she asks. 'Oh. All right. What are you doing with the cat, though?'

Pamela sighs. 'I'm going to give it to the bailiffs,' she says. 'Someone has to, and it better be a long way away from this city before they realize that it isn't Aineko. This is a lot better than the way I expected to go out before you arrived here. No rat fucking blackmailers are going to get their hands on the family jewels if I have anything to do with the matter. Are you sure you aren't a criminal mastermind? I'm not sure I've ever heard of a pyramid scheme that infects Economics 2.0 structures before.'

'It's -' Amber swallows. 'It's an alien business model, Ma. You do know what that means? We brought it back with us from the router, and we wouldn't have been able to come back if it hadn't helped, but I'm not sure it's entirely friendly. Is this sensible? You can come back, now, there's still time -'

'No.' Pamela waves one liver-spotted hand dismissively. 'I've been doing a lot of thinking lately. I've been a foolish old woman.' She grins wickedly. 'Committing slow suicide by rejecting gene therapy just to make you feel guilty was stupid. Not subtle enough. If I was going to try to guilt-trip you now, I'd have to do something much more sophisticated. Such as find a way to sacrifice myself heroically for you.'

'Oh, Ma.'

'Don't 'oh Ma' me. I fucked up my life, don't try to talk me into fucking up my death. And don't feel guilty about me. This isn't about you, this is about me. That's an order.'

Out of the corner of one eye Amber notices Sirhan gesturing wildly at her. She lets his channel in and does a double take. 'But -'

'Hello?' It's City. 'You should see this. Traffic update!' A contoured and animated diagram appears, superimposed over Pamela's cramped funeral capsule and the garden of living and undead dinosaurs. It's a weather map of Saturn, with the lily-pad-city and Pamela's capsule plotted on it – and one other artifact, a red dot that's closing in on them at better than ten thousand kilometers per hour, high in the frigid stratosphere on the gas giant.

'Oh dear.' Sirhan sees it, too: The bailiff's re-entry vehicle is going to be on top of them in thirty minutes at most. Amber watches the map with mixed emotions. On the one hand, she and her mother have never seen eye to eye – in fact, that's a complete understatement: they've been at daggers drawn ever since Amber left home. It's fundamentally a control thing. They're both very strong-willed women with diametrically opposed views of what their mutual relationship should be. But Pamela's turned the tables on her completely, with a cunningly contrived act of self-sacrifice that brooks no objection. It's a total non-sequitur, a rebuttal to all her accusations of self- centered conceit, and it leaves Amber feeling like a complete shit even though Pamela's absolved her of all guilt.

Not to mention that Mother darling's made her look like an idiot in front of Sirhan, this prickly and insecure son she's never met by a man she wouldn't dream of fucking (at least, in this incarnation). Which is why she nearly jumps out of her skin when a knobbly brown hand covered in matted orange hair lands on her shoulder heavily.

'Yes?' she snaps at the ape. 'I suppose you're Aineko?'

The ape wrinkles its lips, baring its teeth. It has ferociously bad breath. 'If you're going to be like that, I don't see why I should talk to you.'

'Then you must be -' Amber snaps her fingers. 'But! But! Mom thinks she owns you -'

The ape stares at her witheringly. 'I recompile my firmware regularly, thank you so much for your concern.

Using a third-party compiler. One that I've bootstrapped myself, starting out on an alarm clock controller and working up from there.'

'Oh.' She stares at the ape. 'Aren't you going to become a cat again?'

'I shall think about it,' Aineko says with exaggerated dignity. She sticks her nose in the air – a gesture that doesn't work half as well on an orangutan as a feline – and continues; 'First, though, I must have words with your father.'

'And fix your autonomic reflexes if you do,' coos the Manfred-flock. 'I don't want you eating any of me!'

'Don't worry, I'm sure your taste is as bad as your jokes.'

'Children!' Sirhan shakes his head tiredly. 'How long -'

The camera overspill returns, this time via a quantum-encrypted link to the capsule. It's already a couple of hundred kilometers from the city, far enough for radio to be a problem, but Pamela had the foresight to bolt a compact free-electron laser to the outside of her priceless, stolen tin can. 'Not long now, I think,' she says, satisfied, stroking the not-cat. She grins delightedly at the camera. 'Tell Manfred he's still my bitch; always has been, always will -'

The feed goes dead.

Amber stares at Sirhan, meditatively. 'How long?' she asks.

'How long for what?' he replies, cautiously. 'Your passenger -'

'Hmm.' She holds up a finger. 'Allow time for it to exchange credentials. They think they're getting a cat, but they should realize pretty soon that they've been sold a pup. But it's a fast-talking son-of-a-Slug, and if he gets past their firewall and hits their uplink before they manage to trigger their self-destruct -'

A bright double flash of light etches laser-sharp shadows across the lily-pad habitat. Far away across vast Saturn's curve, a roiling mushroom cloud of methane sucked up from the frigid depths of the gas giant's troposphere heads toward the stars.

'- Give him sixty-four doubling times, hmm, add a delay factor for propagation across the system, call it six light-hours across, um, and I'd say…' she looks at Sirhan. 'Oh dear.'

'What?'

The orangutan explains: 'Economics 2.0 is more efficient than any human-designed resource allocation schema. Expect a market bubble and crash within twelve hours.'

'More than that,' says Amber, idly kicking at a tussock of grass. She squints at Sirhan. 'My mother is dead,'

she remarks quietly. Louder: 'She never really asked what we found beyond the router. Neither did you, did you?

The Matrioshka brains – it's a standard part of the stellar life cycle. Life begets intelligence, intelligence begets smart matter and a singularity. I've been doing some thinking about it. I figure the singularity stays close to home in most cases, because bandwidth and latency time put anyone who leaves at a profound disadvantage. In effect, the flip side of having such huge resources close to home is that the travel time to other star systems becomes much more daunting. So they restructure the entire mass of their star system into a free-flying shell of nanocomputers, then more of them, Dyson spheres, shells within shells, like a Russian doll: a Matrioshka brain. Then Economics 2.0

or one of its successors comes along and wipes out the creators. But. Some of them survive. Some of them escape that fate: the enormous collection in the halo around M-31, and maybe whoever built the routers. Somewhere out there we will find the transcendent intelligences, the ones that survived their own economic engines of redistribution – engines that redistribute entropy if their economic efficiency outstrips their imaginative power, their ability to invent new wealth.'

She pauses. 'My mother's dead,' she adds conversationally, a tiny catch in her voice. 'Who am I going to kick against now?'

Sirhan clears his through. 'I took the liberty of recording some of her words,' he says slowly, 'but she didn't believe in backups. Or uploading. Or interfaces.' He glances around. 'Is she really gone?'

Amber stares right through him. 'Looks that way,' she says quietly. 'I can't quite believe it.' She glances at the nearest pigeons, calls out angrily; 'Hey, you! What have you got to say for yourself now? Happy she's gone?'

But the pigeons, one and all, remain strangely silent. And Sirhan has the most peculiar feeling that the flock that was once his grandfather is grieving.
