Foundation’s Fear

Rendezvous

“If we stay in our apartment, don’t ever leave Streeling University-”

“No,” R. Daneel Olivaw said sternly. “The situation is too grave.”

“Then where?”

“Off Trantor.”

“I am less acquainted with other worlds.”

Olivaw waved away her point. “I have in mind a remark in your recent report. He is interested in the fundamental human drives.”

Dors frowned. “Yes, Hari keeps saying there are elements still missing.”

“Good. There is a world where he can explore this. Possibly he can find valuable component terms for his model equations.”

“A primitive planet? That would be dangerous.”

“This is a severely underpopulated place, with fewer threats.”

“You have been there?”

“I have been everywhere.”

She realized that this could not be literally true. Quick calculation showed that even R. Daneel Olivaw would have had to visit several thousand worlds in each year of his life. His enduring presence stretched well beyond the twelve thousand years since the founding of the Kambal Dynasty on Trantor. Indeed, she had been told-though this was difficult to believe-that he came forth from the very Origin Eras of interstellar flight, over twenty thousand years ago.

“Why don’t we both go with him-”

“I must remain here. The simulations live on still in the Trantor Mesh. With the MacroMesh about to be connected, they could multiply themselves throughout the Galaxy.”.

“Truly?” She had been concentrating on Hari; the simulations had seemed to be a small side issue.

“I edited them, many millennia ago, to exclude knowledge I felt damaging for humans. But I should revisit that editing.”

“Editing out? Cutting away such information as, for example, Earth’s location?”

“They know minor data, such as how Earth’s moon eclipses its star-an amazingly accurate fit. That could narrow the search.”

“I see.” She had never been told this, and found strange emotions stirred by the knowing.

“I have had to do many such revisitings before. Luckily, individual humans’ memories die with them. Simulations do not.”

She felt a dark, brooding sorrow in his words. More, she caught a glimmer of how he must view events, looking backward down a tunnel of long labor and grim sacrifice, stretching tens of millennia. She was comparatively young, less than two centuries old.

Yet she understood that robots had to be immortal.

This requirement arose because they had to remain ever-vigilant for humanity. Humans accomplished their cultural continuity by passing on to the next generation the essentials that bound them all together.

But robots could not be allowed to regularly reproduce, even though the means were readily adopted from the basic organs of mankind. The robots knew their Darwin.

To reproduce meant to evolve. Inevitably, error would creep into any method of reproduction. Most errors would cause death or subnormal performance, but some would alter the next generation of robots in subtle ways. Some of these would be unacceptable, as seen through the lens of the Four Laws.

The most obvious selection principle, operating in all ordinarily self-reproducing organisms, was for self-interest. Evolution rewarded pressing forward in one’s own cause. Favoring the individual was the central force selecting for survivors.

But the self-interest of a robot could conflict with the Four Laws. Inevitably, a robot would evolve which-despite outward appearances, despite intricate interrogations-would favor itself over humanity. Such a robot would not spring between a human and a speeding vehicle.

Or between humanity and the threats that loomed out of the Galactic night…

So R. Daneel Olivaw, of the Original Design, had to be immortal. Only special-use robots such as herself could be made fresh. The organiform variation had been arrived at over many centuries of secret research. I t was allowed expressly to fill an unusual task at hand, such as forming a cocoon, both emotional and physical, around one Hari Seldon.

“You wish to erase all the simulations, everywhere?”

He said, “Ideally, yes. They might produce new robots, release ancient lore, they could even uncover…”

“Why do you stop?”

“There are historical facts you need not know.”

“But I am an historian.”

“You are closer to human than I. Some knowledge is best left to forms such as myself. Believe me. The Three Laws, plus the Zeroth, have deep implications, ones the Originators did not-could not-guess. Under the Zeroth Law, we robots have had to perform certain acts-” He caught himself, abruptly shook his head.

“Very well,” she said reluctantly, fruitlessly studying his impassive face. “I accept that. And I will go with him to this place.”

“You will need technical aid.” R. Daneel stripped away his shirt to reveal a completely convincing human skin. He put two stiff fingers carefully below one nipple and pushed in a pressure pattern. His chest opened longitudinally for perhaps five centimeters. He removed a jet-black cylinder the size of his little finger. “Instructions are encoded in the side for optical reading.”

“Advanced technology for a backward world?”

He allowed himself a smile. “It should be safe, but precautions are in order. Always. Do not worry overly much. I doubt that even the crafty Lamurk will be able to plant agents quickly on Panucopia.”
