Robert Silverberg - Enter a Soldier. Later - Enter Another

This was the twelfth or thirteenth demonstration that Richardson had subjected him to since he had begun fooling around with this historical-simulation business. The others all had been disasters of one kind or another, and Tanner expected that this one would finish the same way. And basically Tanner was growing uneasy about the project that he once had given his stamp of approval to, so long ago. It was getting harder and harder to go on believing that all this work served any useful purpose. Why had it been allowed to absorb so much of Richardson’s group’s time and so much of the lab’s research budget for so many months? What possible value was it going to have for anybody? What possible use?

It’s just a game, Tanner thought. One more desperate meaningless technological stunt, one more pointless pirouette in a meaningless ballet. The expenditure of vast resources on a display of ingenuity for ingenuity’s sake and nothing else: now there’s decadence for you.

The tiny image in the holotank suddenly began to lose color and definition.

“Uh-oh,” Tanner said. “There it goes. Like all the others.”

But Richardson shook his head. “This time it’s different, Harry.”

“You think?”

“We aren’t losing him. He’s simply moving around in there of his own volition, getting beyond our tracking parameters. Which means that we’ve achieved the high level of autonomy that we were shooting for.”

“Volition, Lew? Autonomy?”

“You know that those are our goals.”

“Yes, I know what our goals are supposed to be,” said Tanner, with some annoyance. “I’m simply not convinced that a loss of focus is a proof that you’ve got volition.”

“Here,” Richardson said. “I’ll cut in the stochastic tracking program. He moves freely, we freely follow him.” Into the computer ear in his lapel he said, “Give me a gain boost, will you?” He made a quick flicking gesture with his left middle finger to indicate the quantitative level.

The little figure in ornate armor and pointed boots grew sharp again. Tanner could see fine details on the armor, the plumed helmet, the tapering shoulder-pieces, the joints at the elbows, the intricate pommel of his sword. He was marching from left to right in a steady hip-rolling way, like a man who was climbing the tallest mountain in the world and didn’t mean to break his stride until he was across the summit. The fact that he was walking in what appeared to be mid-air seemed not to trouble him at all.

“There he is,” Richardson said grandly. “We’ve got him back, all right? The conqueror of Peru, before your very eyes, in the flesh. So to speak.”

Tanner nodded. Pizarro, yes, before his very eyes. And he had to admit that what he saw was impressive and even, somehow, moving. Something about the dogged way with which that small armored figure was moving across the gleaming pearly field of the holotank aroused a kind of sympathy in him. That little man was entirely imaginary, but he didn’t seem to know that, or if he did he wasn’t letting it stop him for a moment: he went plugging on, and on and on, as if he intended actually to get somewhere. Watching that, Tanner was oddly captivated by it, and found himself surprised suddenly to discover that his interest in the entire project was beginning to rekindle.

“Can you make him any bigger?” he asked. “I want to see his face.”

“I can make him big as life,” Richardson said. “Bigger. Any size you like. Here.”

He flicked a finger and the hologram of Pizarro expanded instantaneously to a height of about two meters. The Spaniard halted in mid-stride as though he might actually be aware of the imaging change.

That can’t be possible, Tanner thought. That isn’t a living consciousness out there. Or is it?

Pizarro stood poised easily in mid-air, glowering, shading his eyes as if staring into a dazzling glow. There were brilliant streaks of color in the air all around him, like an aurora. He was a tall, lean man in late middle age with a grizzled beard and a hard, angular face. His lips were thin, his nose was sharp, his eyes were cold, shrewd, keen. It seemed to Tanner that those eyes had come to rest on him, and he felt a chill.

My God, Tanner thought, he’s real .

It had been a French program to begin with, something developed at the Centre Mondiale de la Computation in Lyons about the year 2119. The French had some truly splendid minds working in software in those days. They worked up astounding programs, and then nobody did anything with them. That was their version of Century Twenty-Two Malaise.

The French programmers’ idea was to use holograms of actual historical personages to dress up the son et lumiere tourist events at the great monuments of their national history. Not just preprogrammed robot mockups of the old Disneyland kind, which would stand around in front of Notre Dame or the Arc de Triomphe or the Eiffel Tower and deliver canned spiels, but apparent reincarnations of the genuine great ones, who could freely walk and talk and answer questions and make little quips. Imagine Louis XIV demonstrating the fountains of Versailles, they said, or Picasso leading a tour of Paris museums, or Sartre sitting in his Left Bank café exchanging existential bons mots with passersby! Napoleon! Joan of Arc! Alexandre Dumas! Perhaps the simulations could do even more than that: perhaps they could be designed so well that they would be able to extend and embellish the achievements of their original lifetimes with new accomplishments, a fresh spate of paintings and novels and works of philosophy and great architectural visions by vanished masters.

The concept was simple enough in essence. Write an intelligencing program that could absorb data, digest it, correlate it, and generate further programs based on what you had given it. No real difficulty there. Then start feeding your program with the collected written works—if any—of the person to be simulated: that would provide not only a general sense of his ideas and positions but also of his underlying pattern of approach to situations, his style of thinking—for le style , after all, est l’homme meme . If no collected works happened to be available, why, find works about the subject by his contemporaries, and use those. Next, toss in the totality of the historical record of the subject’s deeds, including all significant subsequent scholarly analyses, making appropriate allowances for conflicts in interpretation—indeed, taking advantages of such conflicts to generate a richer portrait, full of the ambiguities and contradictions that are the inescapable hallmarks of any human being. Now build in substrata of general cultural data of the proper period so that the subject has a loam of references and vocabulary out of which to create thoughts that are appropriate to his place in time and space. Stir. Et voila! Apply a little sophisticated imaging technology and you had a simulation capable of thinking and conversing and behaving as though it is the actual self after which it was patterned.

Of course, this would require a significant chunk of computer power. But that was no problem, in a world where 150-gigaflops networks were standard laboratory items and ten-year-olds carried pencil-sized computers with capacities far beyond the ponderous mainframes of their great-great-grandparents’ day. No, there was no theoretical reason why the French project could not have succeeded. Once the Lyons programmers had worked out the basic intelligencing scheme that was needed to write the rest of the programs, it all should have followed smoothly enough.

Two things went wrong: one rooted in an excess of ambition that may have been a product of the peculiarly French personalities of the original programmers, and the other having to do with an abhorrence of failure typical of the major nations of the midtwenty-second century, of which France was one.
