"No," said Karen. "No, if you don't mind me saying so, it goes deeper than that, I think. Don't you see? The idea that false people can just be manufactured goes to the heart of our religious beliefs. When I say that Prince Scales doesn't really exist, and you've only been fooled into thinking that he does, then I open up the possibility that Moses didn't exist — that some writer just made him up. Or that Mohammed didn't really say and do the things ascribed to him. Or that Jesus is a fictional character, too. The whole of our spiritual existence is based on this unspoken assumption that writers record, but they don't fabricate — and that, even if they did, we could tell the difference."

I looked around the waiting room, here at this place where they mated android bodies with sca

Three more people arrived while we were waiting: others who'd decided to upload.

But the receptionist called for me first, and I left Karen chatting with her fellow very senior citizens. I followed the receptionist down the brightly lit corridor, enjoying the swaying of her youthful hips, and was taken to an office with walls that looked gray to me — meaning they could have been that color, or green, or magenta.

"Hello, Jake," said Dr. Porter, rising from his chair. "Good to see you again."

Andrew Porter was a tall bear of a man, sixty or so, slightly stooped from dealing with a world populated by shorter people. He had squinty eyes, a beard, and hair combed straight back from a high forehead. His kindly face was home to eyebrows that seemed constantly in motion, as if they were working out, in training for the body-hair Olympics.

"Hello, Dr. Porter," I said. I'd seen him twice before now, on previous visits here, during which I'd undergone various medical tests, filled out legal forms, and had my body — but not yet my brain — sca

"Are you ready to see it?" asked Porter.

I swallowed, then nodded.

"Good, good." There was another door to the room, and Porter opened it with a theatrical flourish. "Jake Sullivan," he declared, "welcome to your new home!"

In the next room, lying on a gurney, was a synthetic body, wearing a white terry-cloth robe.

I felt my jaw dropping as I looked down at it. The resemblance was remarkable.

Although there was a touch of department-store ma

"The boys and girls in Physiognomy tell me you were a cinch," said Porter, gri

"Usually, we're trying to roll back the clock several decades, recreating what a person had looked like when they were in their prime; after all, no one wants to upload into a body that looks like it's on its last legs. You're the youngest person they've ever had to do."

It was my face, all right — the same long shape; the same cleft chin; the same thin lips; the same wide mouth; the same close-together eyes, the same dark eyebrows above them. Crowning it all was thick dark hair. All the gray had been removed, and — I craned to look — the duplicate had no bald spot.

"A few minor touch-ups," said Porter, gri

I'm sure I was gri

"We're pleased. Of course, the underlying synthetic skull is identical in shape to yours — it was made with 3D-prototyping equipment from the stereo x-rays we took; it even has the same pattern of sutures, marking where the separate skull bones fused together."

I'd had to sign a release for the extensive x-rays used to produce the artificial skeleton. I'd received a big enough dose in one day to increase my future likelihood of cancer — but, then again, most Immortex clients were going to die soon, long before any cancers could pose a problem.

Porter touched the side of the simulated head; the jaw opened, revealing the highly detailed mouth within.

"The teeth are exact copies of your own layout — we've even embedded a denser ceramic composite at the right points to match the two fillings you have: dental biometrics would identify this head as being yours. Now, you can see there's a tongue, but, of course, we don't actually use the tongue for speech; that's all done with voice-synthesizer chips. But it should do a pretty good job of faking it. The opening and closing of the jaw will match the sounds being produced perfectly — kind of like Supermarionation."

"Like what?" I said.

"Thunderbirds? Captain Scarlet?"

I shook my head.

Porter sighed. "Well, anyway, the tongue is very complex — the most complex part of the recreation, actually. It doesn't have taste buds, since you won't need to eat, but it is pressure sensitive and, as I said, it will make the appropriate movements to match what your voice chip is saying."

"It's really … unca

Porter laughed, but then pointed at me. "Now, sadly we haven't been able to replicate that: when you smile, you've got a great dimple in your left cheek. The artificial head doesn't do that. We've noted it in your file, though — I'm sure we'll be able to add it in a future upgrade."

"That's okay," I said. "You've done a terrific job as is."

"Thanks. We like people to become familiar with the appearance before we transfer them into an artificial body — it's good that you know what to expect. Are there any particular activities you're looking forward to?"

"Baseball," I said at once.

"That will take a lot of eye-hand coordination, but it will come."

"I want to be as good as Singh-Samagh."

"Who?" asked Porter.

"He's a starting pitcher for the Blue Jays."

"Oh. I don't follow the game. I can't guarantee you'll ever be professional caliber, but you'll definitely be at least as good, if not better, than you were before."

He went on. "You'll find that all the proportions are exactly the same as your current body — the length of each finger segment, of each limb segment, and so on. Your mind has built up a very sophisticated model of what your body is like — how long your arms are, at what point along their length the elbow or knee occurs, et cetera.

That mental model is adaptable while you're still growing, but becomes pretty firmly entrenched in middle age. We've tried making short people tall, and correcting for mismatched limb lengths, but it created more problems than it was worth — people have a lot of trouble adjusting to a body that isn't like their original."

"Urn, does that mean…? I'd thought…"

Porter laughed. "Ah, yes. We do mention that in our literature. Well, you see, the male sex organ is a special case: it varies substantially in size depending on temperature, arousal, and so on. So, yes, as a matter of course, we upsize what nature provided in the original, unless you specifically indicated you didn't want that on the forms you filled out; the mind is already used to the penis having variable form, so it seems to deal well with an extra few centimeters." Porter pulled at the terry-cloth sash holding the robe closed.

"My goodness," I said, feeling awfully silly, but also awfully impressed. "Um, thank you."

"We aim to please," said Porter, with a beatific smile.

Ray Kurzweil had been the most vocal proponent around the time I was born of moving our minds into artificial bodies. His books from that time — the classic is The Age of Spiritual Machines, from 1999 — proposed that within thirty years of then (meaning sixteen years ago from now) — it would be possible to copy "the locations, interco
