Отрывок из романа "FLASHFORWARD".
"Do you know who Frank Tipler is?"
Lloyd frowned. "A candid drunk?"
"What? Oh, I get it—but it’s Tipler with one P. He wrote The Physics of Immortality."
"The Physics of what?" said Lloyd, eyebrows rising.
"Immortality. Living forever. It’s what you always wanted, isn’t it? All the time in the world; all the time to do all the things you want to do. Well, Tipler says that at the Omega Point—the end of time—we will all be resurrected and live forever."
"What kind of gibberish is that?"
"I admit it’s a whopper," said Michiko. "But he made a good case."
"Oh?" said Lloyd, the syllable pregnant with skepticism.
"He says that computer-based life will eventually supplant biological life, and that information-processing capabilities will continue to expand year after year, until at some point, in the far future, no conceivable computing problem will be impossible. There will be nothing that the future machine life won’t have the power and resources to calculate."
"Now, consider an exact, specific description of every atom in a human body: what type it is, where it is located, and how it relates to the other atoms in the body. If you knew that, you could resurrect a person in his entirety: an exact duplicate, right down to the unique memories stored in the brain and the exact sequence of nucleotides making up his DNA. Tipler says that a sufficiently advanced computer far enough in the future could easily recreate you, just by building up a simulacrum that reflects the same information—the same atoms, in the same places."
"But there’s no record of me. You can’t reconstruct me without—I don’t know—some kind of scan of me . . . something like that."
"It doesn’t matter. You could be reproduced without any specific info about you."
"What are you talking about?"
"Tipler says there are about 110,000 active genes that make up a human being. That means that all the possible permutations of those genes—all the possible biologically distinct human beings that could conceivably exist—amount to about ten to the tenth to the sixth different people. So if you were to simulate all those permutations—"
"Simulate ten to the tenth to the sixth human beings?" said Lloyd. "Come on!"
"It all follows from saying that you have essentially infinite information-processing capabilities," said Michiko. "There may be oodles of possible humans, but it is a finite number."
"Just barely finite."
"There are also a finite number of possible memory states. With enough storage capacity, not only could you reproduce every possible human being, but also every possible set of memories each of them could have."
"But you’d need one simulated human for every memory state," said Lloyd. "One in which I ate pizza last night—or at least had memories of doing that. Another in which I ate a hamburger. Et cetera, et cetera, ad nauseam."
"Exactly. But Tipler says you could reproduce all possible humans that could ever exist, and all possible memories that they could ever have, in ten to the tenth to the twenty-third bits."
"Ten to the tenth to the . . ."
"Ten to the tenth to the twenty-third."
"That’s crazy," said Lloyd.
"It’s a finite quantity. And it could all be reproduced on a sufficiently advanced computer."
"But why would anyone do that?"
"Well, Tipler says the Omega Point loves us, and—"
"You really should read the book; he makes it sound much more reasonable than I do."
"He’d pretty much have to," said Lloyd, deadpan.
