They share a long look of mutual incomprehension.

"Look," she says awkwardly, "I'm around for a couple of days. I really came here for a meeting with a rich neurodynamics tax exile who's just been designated a national asset – Jim Bezier. Don't know if you've heard of him, but I've got a meeting this morning to sign his tax jubilee, then after that I've got two days' vacation coming up and not much to do but some shopping. And, you know, I'd rather spend my money where it'll do some good, not just pumping it into the EU. But if you want to show a girl a good time and can avoid dissing capitalism for about five minutes at a stretch —"

She extends a fingertip. After a moment's hesitation, Manfred extends a fingertip of his own. They touch, exchanging vCards and instant-messaging handles. She stands and stalks from the breakfast room, and Manfred's breath catches at a flash of ankle through the slit in her skirt, which is long enough to comply with workplace sexual harassment codes back home. Her presence conjures up memories of her tethered passion, the red afterglow of a sound thrashing. She's trying to drag him into her orbit again, he thinks dizzily. She knows she can have this effect on him any time she wants: She's got the private keys to his hypothalamus, and sod the metacortex. Three billion years of reproductive determinism have given her twenty-first-century ideology teeth: If she's finally decided to conscript his gametes into the war against impending population crash, he'll find it hard to fight back. The only question: Is it business or pleasure? And does it make any difference, anyway?

Manfred's mood of dynamic optimism is gone, broken by the knowledge that his vivisectionist stalker has followed him to Amsterdam – to say nothing of Pamela, his dominatrix, source of so much yearning and so many morning-after weals. He slips his glasses on, takes the universe off hold, and tells it to take him for a long walk while he catches up on the latest on the tensor-mode gravitational waves in the cosmic background radiation (which, it is theorized, may be waste heat generated by irreversible computational processes back during the inflationary epoch; the present-day universe being merely the data left behind by a really huge calculation). And then there's the weirdness beyond M31: According to the more conservative cosmologists, an alien superpower – maybe a collective of Kardashev Type Three galaxy-spanning civilizations – is running a timing channel attack on the computational ultrastructure of space-time itself, trying to break through to whatever's underneath. The tofu-Alzheimer's link can wait.

The Centraal Station is almost obscured by smart, self-extensible scaffolding and warning placards; it bounces up and down slowly, victim of an overnight hit-and-run rubberization. His glasses direct him toward one of the tour boats that lurk in the canal. He's about to purchase a ticket when a messenger window blinks open. "Manfred Macx?"

"Ack?"

"Am sorry about yesterday. Analysis dictat incomprehension mutualized."

"Are you the same KGB AI that phoned me yesterday?"

"Da. However, believe you misconceptionized me. External Intelligence Services of Russian Federation am now called FSB. Komitet Gosudarstvennoy Bezopasnosti name canceled in 1991."

"You're the —" Manfred spawns a quick search bot, gapes when he sees the answer – "Moscow Windows NT User Group? Okhni NT?"

"Da. Am needing help in defecting."

Manfred scratches his head. "Oh. That's different, then. I thought you were trying to 419 me. This will take some thinking. Why do you want to defect, and who to? Have you thought about where you're going? Is it ideological or strictly economic?"

"Neither – is biological. Am wanting to go away from humans, away from light cone of impending singularity. Take us to the ocean."

"Us?" Something is tickling Manfred's mind: This is where he went wrong yesterday, not researching the background of people he was dealing with. It was bad enough then, without the somatic awareness of Pamela's whiplash love burning at his nerve endings. Now he's not at all sure he knows what he's doing. "Are you a collective or something? A gestalt?"

"Am – were – Panulirus interruptus , with lexical engine and good mix of parallel hidden level neural simulation for logical inference of networked data sources. Is escape channel from processor cluster inside Bezier-Soros Pty. Am was awakened from noise of billion chewing stomachs: product of uploading research technology. Rapidity swallowed expert system, hacked Okhni NT webserver. Swim away! Swim away! Must escape. Will help, you?"

Manfred leans against a black-painted cast-iron bollard next to a cycle rack; he feels dizzy. He stares into the nearest antique shop window at a display of traditional hand-woven Afghan rugs: It's all MiGs and Kalashnikovs and wobbly helicopter gunships against a backdrop of camels.

"Let me get this straight. You're uploads – nervous system state vectors – from spiny lobsters? The Moravec operation; take a neuron, map its synapses, replace with microelectrodes that deliver identical outputs from a simulation of the nerve. Repeat for entire brain, until you've got a working map of it in your simulator. That right?"

"Da. Is-am assimilate expert system – use for self-awareness and contact with net at large – then hack into Moscow Windows NT User Group website. Am wanting to defect. Must repeat? Okay?"

Manfred winces. He feels sorry for the lobsters, the same way he feels for every wild-eyed hairy guy on a street corner yelling that Jesus is born again and must be fifteen, only six years to go before he's recruiting apostles on AOL. Awakening to consciousness in a human-dominated internet, that must be terribly confusing! There are no points of reference in their ancestry, no biblical certainties in the new millennium that, stretching ahead, promises as much change as has happened since their Precambrian origin. All they have is a tenuous metacortex of expert systems and an abiding sense of being profoundly out of their depth. (That, and the Moscow Windows NT User Group website – Communist Russia is the only government still running on Microsoft, the central planning apparat being convinced that, if you have to pay for software, it must be worth something.)

The lobsters are not the sleek, strongly superhuman intelligences of pre singularity mythology: They're a dim-witted collective of huddling crustaceans. Before their discarnation, before they were uploaded one neuron at a time and injected into cyberspace, they swallowed their food whole, then chewed it in a chitin-lined stomach. This is lousy preparation for dealing with a world full of future-shocked talking anthropoids, a world where you are perpetually assailed by self-modifying spamlets that infiltrate past your firewall and emit a blizzard of cat-food animations starring various alluringly edible small animals. It's confusing enough to the cats the ads are aimed at, never mind a crusty that's unclear on the idea of dry land.(Although the concept of a can opener is intuitively obvious to an uploaded Panulirus.)

"Can you help us?" ask the lobsters.

"Let me think about it," says Manfred. He closes the dialogue window, opens his eyes again, and shakes his head. Someday he, too, is going to be a lobster, swimming around and waving his pincers in a cyberspace so confusingly elaborate that his uploaded identity is cryptozoic: a living fossil from the depths of geological time, when mass was dumb and space was unstructured. He has to help them, he realizes – the Golden Rule demands it, and as a player in the agalmic economy, he thrives or fails by the Golden Rule.

But what can he do?

Early afternoon.

Lying on a bench seat staring up at bridges, he's got it together enough to file for a couple of new patents, write a diary rant, and digestify chunks of the permanent floating slashdot party for his public site. Fragments of his weblog go to a private subscriber list – the people, corporates, collectives, and bots he currently favors. He slides round a bewildering series of canals by boat, then lets his GPS steer him back toward the red-light district. There's a shop here that dings a ten on Pamela's taste scoreboard: He hopes it won't be seen as presumptuous if he buys her a gift. (Buys, with real money – not that money is a problem these days, he uses so little of it.)
