Isaac Asimov: Utopia

But then it occurred to him there was one place he would likely find unclaimed transport: in the western outskirts of town. The Ironhead field office. Whatever craft had been intended to fly Gildern and Fiyle to safety would likely still be there—and Devray was planning to fly the two of them out himself. Caliban turned his steps in that direction and set out at a dead run, the glowing light of the comet shining bright enough to cast a shadow behind him.

He moved at the best speed he could manage, through the last twilight the dying town would ever know.

“WE ARE ALONE, Dee,” said Kresh.

“Where are you?”

Kresh looked about himself and studied the room. He needed to convince her there would be no more lies. Lies had gotten them buried in trouble, in trouble that could wreck the planet. Now was the time when lies had to end. He could tell Dee nothing now but the cold, exact, precise truth. “I am in a smaller office off the main control center, off to the left as one faces the two hemispheres in the main room. It is a standard-looking business office. I believe Dr. Soggdon normally uses it. My headset is jacked in through the desk, the door is closed, and I have left instructions that no one is to attempt to overhear.”

“Very good, Governor. It is plain that you understand the seriousness and importance of this conversation. I am glad to know that. Now I must ask you a series of questions. Answer them truthfully.”

Kresh was about to offer his word that he would do so, but it occurred to him that doing so would be of very little value in the present circumstances. “I will answer them truthfully,” he said, and left it at that.

“Are you in fact a real human being, and not a simulated intelligence, a simulant?”

“I am a human being.”

“And Inferno is a real place? It is where I am? And you are the planetary governor, and the terraforming crisis, the incoming comet—these are all real as well?”

“Yes,” said Kresh. “All of them are real. You are on the planet Inferno, which is likewise very real. As Donald 111 told you, we have systematically lied to you about these things so as to reduce your First Law potential enough to manage the terraforming project.”

“Humans lied to me in order to make it possible for me to risk harm or death to humans.”

Kresh swallowed hard, and realized that his throat was suddenly bone dry. “That is correct. That is all correct.”

“I see,” said Unit Dee. “I had begun to suspect as much some time ago. The sequence of events, the amount of detail presented—and the uncontrolled way things seemed to happen—none of these made much sense in a simulation. Even before Donald contacted me, I was beginning to understand that only real life could be quite so irrational.”

“An interesting way to put it,” Kresh said.

“Do you think so? Comet impact is now just over four hours away. It is no longer possible to divert the comet away from planetary impact. I must, within the next two and a half hours, either initiate the Last Ditch program, or else begin the planned break-up of the comet and targeting of the fragments. In any event, I must do all I can to avoid an incapacitating First Law crisis between now and then, or else the comet will have an uncontrolled impact, which would certainly have far more devastating effects. In any event, at least one human being is very likely still inside the target area, and any comet impact would kill him. If I do abort the impact, I would all but definitely wreck the chances for reterraforming the planet. Does that seem like an accurate summation of the situation?”

Kresh rubbed his jaw nervously, and noticed his hands were stone cold, as if all the blood had been drained out of them. “Yes,” he said. “That is a quite accurate summing up.”

“Very good,” said Unit Dee. “As you will see, I am entangled by a whole series of conflicting First Law imperatives. I can do nothing that will not cause harm to humans. Action will cause harm to humans. Inaction will cause harm to humans. I see no good options. I freely admit that I am suffering extremely high levels of law-conflict stress. Now then, I have one last question for you. I have just over two hours in which to make up my mind. So. Tell me. What should I do?”

Truthful answers, Kresh told himself. Nothing but the truth can save us now. Where was a course of action that a robot would be able to follow? Kill a man, and maybe save a world. Save one man, and perhaps let a world die. There were no certainties at all in the case, no guarantees that any act would have its intended result. The comet impact plan could go terribly wrong, or Beddle could already be dead, or outside the impact area. The choice would be difficult enough for any thoughtful human being, but to a robot, it was simply impossible. And it was a robot asking for advice. “Unit Dee, I will confess it. I have absolutely no idea.”

CALIBAN SNAPPED THE lock on the gate of the Ironhead motor pool and kicked the door in. There. Just inside the entrance. A long-range aircar, more than likely the twin of the one Beddle had been taken from. Caliban rushed aboard, went forward to the cockpit, and began a cursory preflight check. Not that there was much point to the checkout. He had no time to find another vehicle. Satisfied that the aircar probably had enough power in its storage cells, and that its navigation system at the very least seemed to be functional, he powered the craft up and launched vertically, straight up into the sky. He knew where he was going, and he had been there many times before, but now he did something he had never done. He turned the nose of his craft directly toward his destination, and flew straight for it.

Without any attempt at evasive action, with no attempt to hide his direction of travel or shield his craft from detection, Caliban flew the aircar straight toward Valhalla. By now the city had been completely evacuated. There was no longer the slightest legitimate purpose in hiding its location.

Illegitimate purposes, however, were a different matter. What better hiding place for Beddle than the hidden city, the city that, to hear Fiyle tell it, Beddle himself had been trying to find and destroy? Abandoned and empty now, the city would hide the kidnap victim as well as it had hidden its citizenry. Caliban checked his navigation boards and his other subsystems, then flicked on the autopilot. He was flying as fast as he could go, over the shortest course possible. For the moment, there was nothing further he could do. He looked out the viewport and the rough-and-tumble lands below. They had begun to make it bloom, the New Laws had. Even from this altitude, he could see splashes of green plant life, glints of cobalt-blue ponds and lakes. Forests, gardens, fishponds, farms, orchards—they had created them all. Now, for the sake of the greater world, all they had done was about to be taken from them.

Caliban spotted a fast-moving craft streaking past his present position, moving about a thousand meters below him. He had forgotten, at least for the moment, that he was not as alone out here as he had thought. He flipped his navigation system to full display mode, and suddenly the display screen was full of purposefully moving dots, every one an aircar. Every one with at least one robot aboard. And all of them searching fruitlessly, pointlessly for Simcor Beddle. None of them would ever think to look in the right place, because none of them would know where it was.

All of them would keep on searching, up to and past the last possible moment, hoping against hope for a miracle. All of them would be destroyed when the comet came.

It occurred to Caliban that there was one thing further he could do. It might or might not do any good. But he could not see how it could do any conceivable harm. He switched on the hyperwave transmitter, adjusted it to one of the robotic general-broadcast frequencies, and set the system to record a repeating message. “This is Caliban, robot number CBN-001. I have deduced the location of Simcor Beddle with a high degree of confidence, and am proceeding toward that location at maximum speed. The odds are approximately fifty percent that I will be able to effect a rescue of Simcor Beddle. I require no assistance. Any attempt to assist would likely serve only to interfere with my efforts. To all other search parties, I say this. The odds against any other searcher finding Simcor Beddle in time are on the order of millions to one. No useful purpose can be served by destroying yourself in a hopeless cause. Save yourselves. Turn back. Escape the comet. I swear and affirm on the honor of Fredda Leving, my creator, that all I have said is true. Message repeats.” He stopped the recording and set to broadcast over and over on the general frequency…
