Caliban

Fredda Leving felt an ache in the pit of her stomach and a throbbing pain in her head. It was time to speak truths she had not been able to face. “My point, Jomaine, is that Calibanis dangerous. At least we must work on theassumption that he is. Perhaps hedid attack me. You and I know better than anyone else, there was nothing, literally nothing at all, to stop him. Maybe he intends to track me down and finish me off. Who knows?

“Yes, maybe Caliban will simply go into hiding, or vanish into the desert, or malfunction somehow. At first, I was hoping Caliban would allow his power pack to run down, or that he would allow himself to be caught and destroyed before he could get into serious trouble-or reveal his true nature. Those seemed reasonable hopes. After all, he was designed to be a laboratory test robot. We deliberately never programmed him to deal with the outside world. And yet he has survived, somehow, and taught himself enough that he can evade the police.”

“I suppose we can blame Gubber Anshaw for that,” Jomaine said. “The whole idea of the gravitonic brain was that it was to be more flexible and adaptive than overly rigid positronic brains.” Jomaine smiled bleakly, his face dimly visible in the semidarkness of the aircar’s cabin. “Gubber, it seemed, did his job entirely too well.”

“He’s not the only one, Jomaine.” Fredda rubbed her forehead wearily. “You and I did the basal programming on him. We took Gubber’s flexible gravitonic brain and wrote the program that would allow that brain to adapt and grow and learn in our lab tests. It’s just that he stumbled into a slightly larger laboratory than the one we planned.” She shook her head again. “But I had no idea his gravitonic brain would be adaptive enough to survive out there,” she said, speaking not so much to Jomaine as to the dark and open air.

“I don’t understand,” Jomaine said. “You say he’s dangerous, but you sound more like you’re worried about him than frightened of him.”

“Iam worried about him,” Fredda said. “I created him, and I’m responsible for him, and I cannot believe he is evil or violent. We didn’t give him Laws that would prevent him from harming people, but we didn’t give him anyreason to hurt people either. Half of what we did on the personality coding was compensation for the absence of the Three Laws, making his mind as stable, as well grounded, as we could. And we did our jobright. I’m certain of that. He’s not a killer.”

Jomaine cleared his throat gently. “That’s all as may be,” he said. “But there is another factor. Now that we are at last discussing the situation openly, we need to consider thenature of the experiment we planned to perform with Caliban. No matter what else you say about the stability of his personality, or the flexibility of his mind, he was after all built to run one test, designed to answer one question. And when he walked out of your lab, he was primed and ready for that task. He could not help seeking out the answer. He is in all likelihood unaware of what he is looking for, or even that heis looking. But he will be looking, seeking, burning to discover it, even so.”

The aircar eased itself to a halt in midair, then began to sink lower. They had arrived at Jomaine’s house, hard by Leving Labs, close to where it had all begun. The car landed on his roof and the hatch sighed open. The cabin light came gently up. Jomaine stood and reached out to Fredda across the narrow cabin, took her hand and squeezed it. “There is a great deal you have to think about, Fredda Leving. But no one can protect you anymore. Not now. The stakes are far too high. I think you had best start asking yourself what sort of answer Caliban is likely to come up with.”

Fredda nodded. “I understand,” she said. “But remember that you are as deeply involved as I am. I can’t expect you to protect me-but remember, we will sink or swim together.”

“That’s not strictly true, Fredda,” Jomaine said. His voice was quiet, gentle, with no hint of threat or malice. His tone made it clear that he was setting out facts, not trying to scare her. “Remember that you, not I, designed the final programming of Caliban ‘ s brain. I have the documentation to prove it, by the way. Yes, we worked together, and no doubt a court could find me guilty of some lesser charge. But it was your plan, your idea, your experiment. If that brain should prove capable of assault, or murder, the blood will be on your hands, not mine. “

With that, he looked into her eyes for the space of a dozen heartbeats, and then turned away. There was nothing left to say.
