"What's it promising?" Sirhan asks tensely.

Aineko looks at him through slitted eyes, a purring buzz at the base of his throat: "Everything."

"There are different kinds of death," the woman called Pamela tells Ma

"Simple old-fashioned death, the kind that predated the singularity, used to be the inevitable halting state for all life-forms. Fairy tales about afterlives notwithstanding." A dry chuckle: "I used to try to believe a different one before breakfast every day, you know, just in case Pascal's wager was right – exploring the phase-space of all possible resurrections, you know? But I think at this point we can agree that Dawkins was right. Human consciousness is vulnerable to certain types of transmissible memetic virus, and religions that promise life beyond death are a particularly pernicious example because they exploit our natural aversion to halting states."

"Now, consciousness. That's a fun thing, isn't it? Product of an arms race between predators and prey. If you watch a cat creeping up on a mouse, you'll be able to impute to the cat intentions that are most easily explained by the cat having a theory of mind concerning the mouse – an internal simulation of the mouse's likely behavior when it notices the predator. Which way to run, for example. And the cat will use its theory of mind to optimize its attack strategy. Meanwhile, prey species that are complex enough to have a theory of mind are at a defensive advantage if they can anticipate a predator's actions. Eventually this very mammalian arms race gave us a species of social ape that used its theory of mind to facilitate signaling – so the tribe could work collectively – and then reflexively, to simulate the individual's own i

Get me out of this! Ma

"So," Pamela continues remorselessly, "we come to the posthuman. Not just our own neural wetware, mapped out to the subcellular level and executed in an emulation environment on a honking great big computer, like this: That's not posthuman, that's a travesty. I'm talking about beings who are fundamentally better consciousness engines than us merely human types, augmented or otherwise. They're not just better at cooperation – witness Economics 2.0 for a classic demonstration of that – but better at simulation. A posthuman can build an internal model of a human-level intelligence that is, well, as cognitively strong as the original. You or I may think we know what makes other people tick, but we're quite often wrong, whereas real posthumans can actually simulate us, i

"We should have known better than to keep upgrading the cat, Ma

"Out —" Manfred stops. He can see again, and move, and feel his mouth. He's himself again, physically back as he was in his late twenties all those decades ago when he'd lived a peripatetic life in presingularity Europe. He's sitting on the edge of a bed in a charmingly themed Amsterdam hotel with a recurrent motif of philosophers, wearing jeans and collarless shirt and a vest of pockets crammed with the detritus of a long-obsolete personal area network, his crazily clunky projection specs sitting on the bedside table. Pamela stands stiffly in front of the door, watching him. She's not the withered travesty he remembers seeing on Saturn, a half-blind Fate leaning on the shoulder of his grandson. Nor is she the vengeful Fury of Paris, or the scheming fundamentalist devil of the Belt. Wearing a sharply tailored suit over a red-and-gold brocade corset, blonde hair drawn back like fine wire in a tight chignon, she's the focused, driven force of nature he first fell in love with: repression, domination, his very own strict machine.

"We're dead," she says, then gives voice to a tense half laugh: "We don't have to live through the bad times again if we don't want to."

"What is this?" he asks, his mouth dry.

"It's the reproductive imperative." She sniffs. "Come on, stand up. Come here."

He stands up obediently, but makes no move toward her. "Whose imperative?"

"Not ours." Her cheek twitches. "You find things out when you're dead. That fucking cat has got a lot of questions to answer."

"You're telling me that —"

She shrugs. "Can you think of any other explanation for all this?" Then she steps forward and takes his hand. "Division and recombination. Partitioning of memetic replicators into different groups, then careful cross-fertilization. Aineko wasn't just breeding a better Macx when he arranged all those odd marriages and divorces and eigenparents and forked uploads – Aineko is trying to breed our minds." Her fingers are slim and cool in his hand. He feels a momentary revulsion, as of the grave, and he shudders before he realizes it's his conditioning cutting in. Crudely implanted reflexes that shouldn't still be active after all this time. "Even our divorce. If —"

"Surely not." Ma
