Yod had a presence, perhaps what Malkah had meant by calling it a person. Gimel simply was, with no more impact than a cleaning robot or a beverage cart. Yod, however, created a set of demands simply by fixing her with those hungry eyes and expecting … what? Knowledge, attention, information to devour: after all, that was what she was here to impart. But she would not think of it as a kind of overgrown child to whom she was acting as governess.
She started, however, as she would have with a child, with a battery of tests. For the rest of the day she administered the common sets. By noon she was tired, although of course Yod was not. It would have sat and happily taken tests for a year, she suspected. Answering questions and summoning information was one of its functions, and it could do it forever. How Gadi had hated exams. Avram had in a sense created the student he had wanted and not gotten in his son: a learning machine. In some aspects of intellectual development and ability, Yod scored vastly above the human range; in others, it was well within ordinary human parameters. It was like a bright child, perhaps the sort of child Josh had been, forward in its command of the sciences and of mathematics but quite retarded in its grasp of human relationships and the subtler values. Metaphorical thinking seemed to stymie it. It tended to interpret discourse literally.
On their second day together, she began where she had left off: with metaphorical thinking, the ability to create analogies. She administered a simple test designed for very young children. His score was zero. She tried on Yod the Robert Burns lyric:
O, my luve is like a red, red rose
That’s newly sprung in June.
O, my luve is like the melodie
That’s sweetly play’d in tune.
It was a washout. “He was a botanist? A musician?”
“Yod, think of a rose.”
“A rose is a flower closely related to a number of edible fruits. Sometimes its hips are eaten as soup or jelly, but usually they were harvested in the past by birds. Roses are a common gift to show affection. They possess colour, fragrance, form ―”
“Have you ever seen a rose?”
“In the dictionary program.”
“I mean a real rose.”
“No.” Yod managed to imitate regret in its deep voice.
“There are roses growing along the south side of this building, old pillar roses, red and pink. Haven’t you ever noticed them?”
“I’ve never seen the outside of this building.”
“You’ve never been out of the lab?”
“I’ve been in Avram’s flat, before Gadi came to visit. Almost every night I go down to the basement, where Avram has set up a gym. There I practice my martial arts with Gimel. He’s sufficient to give me a challenge I couldn’t get from a human partner.”
“But you’ve never been outside?”
“Never. Avram always says I am not ready. Can you make me ready?”
“I don’t think you’ll ever get ready if we stay in the lab. I’m going to take you out right now, to my house.” It occurred to her that Avram would be furious, but she had to proceed in her own way. “Now, on the street we have only two blocks to walk ― you know what a block is?”
“The plan of the town is in my memory.”
“While we’re outside, you walk beside me and keep your mouth shut.”
Yod shut its mouth tightly, as if keeping a large mouthful inside.
“I don’t mean that literally. I mean you should not speak to anyone beyond saying hello if anyone speaks directly to you. If I have to introduce you, your name is … Yod Oblensky. You’re a cousin of Avram’s. I’ll do all the rest of the talking. Do you understand?”
It grinned so widely its face seemed to split open. “Thank you, Shira. I’ve longed to go outside. I think about it every day. I even considered going quietly on my own, but Avram locks me in and I’m not willing to break the lock.”
“Could you? That’s a very high-security lock.”
“I could break it.”
She was startled by Yod’s confessing that it had thought of disobeying Avram. She had always understood that a robot could not disobey. After all, it had not done so, but that it could even frame such a possibility astonished her. She had to find out quickly how real its apparent ability to master new situations was and how much it was capable of learning that went beyond the collection and regurgitation of facts. Taking Yod out was the first procedure in her exploration of its true capacity.
As she had expected, at this time of the morning few people were on the streets. It was a third of the way into the average workday, and even people who worked a split shift or who went to work early or late were all on the job. Children were in day care or in school. Only a streetcleaning robot came rattling along the street, stopping to pick up trash and sweep.
As it came up level to them, it darted forward to spear a piece of debris. Instantly Yod flung himself upon it, seized it, smashed it against the curb. The curb cracked with the impact. “Yod! That’s a street cleaner. Come. Quickly. I don’t want to have to explain this.”
Yod bent over the mangled mechanism. “It could have been a bomb. I see now. A cleaning mechanism?”
“How do you feel when you see such a mechanism? Do you feel a sense of kinship?” She must be losing her mind, asking a machine how it felt.
Yod rose to rejoin her. When it was not in its security mode, it moved with surprising grace. “Do you feel a sense of kinship when you eat telapia?”
“Why should I?”
“You’re as closely related biologically to that fish as I am as a mechanism to that cleaning robot. Perhaps you’re closer.”
She glanced sideways at Yod. “Put me in my place, didn’t you?”
“Your place?” Gingerly it took her by the shoulders. Your place is at the end of the street, correct?”
“I was speaking metaphorically. Do not actually put me anyplace. Just walk on, please.”
The cyborg was craning around, swinging suddenly to survey the street behind them. Suddenly it sprang into attack posture.
“You’re going to have to learn to use metaphor and simile, Yod, if you’re ever to sound halfway human. By the way, that’s a dog. It is not an attack dog. It’s called a spaniel, and it’s friendly.”
“This incessant comparing of unlike things in ways that imply some point of similarity is important puzzles me.” Yod reluctantly left the dog wagging its tail. “How can you tell whether such an animal is friendly?”
“In here.” The door opened as she touched it. “Attack dogs attack. They may growl first or just attack. Most dogs wag their tails and wait to see your intentions. We communicate mammal to mammal, but I don’t know how you smell to a dog, frankly.”
“Welcome, Shira,” the house said. “What is the mechanism with you?”
“It’s a cyborg named Yod. You are to treat it as a person. Protect it.”
The house did not answer immediately. This was one of those times when she felt as if the personality of the house, constant since Shira’s earliest memories, were not artificial but real. She could not help feeling that the house was disapproving of her request. Finally the house said, “Request noted, Shira.”
“Thank you,” Yod said. “That was kind of you. I can talk now?”
“House, don’t let anyone in except Malkah. Yes, you can talk.”
“The sky isn’t blue. I had expected it to be blue from information I was given in my dictionary ―”
“You see colour, then.”
“I assumed you looked at Avram’s design specs.”
“Yod, there’s the equivalent of an encyclopedia of material there. I hit a few highlights.”
“I could read through it in a matter of hours. Yes, I see colour as you do, although I can alter my vision to pick up infrared or ultraviolet if required ― for instance, in a surveillance situation.”
“The sky is not blue because of the greenhouse effect. We hope someday the sky will be blue again … Were you disappointed?” she asked as an experiment. She wanted to see if the cyborg understood the concept.
“It wasn’t as I expected it.” Yod paused, frowning. It had been given complex programming to reproduce the equivalent of human facial expressions, and at times she found its artificial responsiveness disconcerting. “I suppose it’s correct to say that I am disappointed, if disappointment implies that something did not meet my expectations.”
She led him straight through to the courtyard. “Look. Now, that’s a rose.”
Yod strode towards it and reached out to examine a flower. Then with an exclamation it yanked its hand back. “It is armed.” It seized the enormous old climbing rose and ripped it from the wall, trellis and staples and all, twisting it so that it uprooted.
“Yod! What have you done!” She struck the cyborg before she thought, in fury. Hitting him felt very like hitting a person except that he did not flinch. “That rosebush was sixty years old. I loved those roses!”
It stood looking at the enormous vine yanked from the courtyard wall. “I’ve angered you.”
“Yod, I should not have hit you.” It didn’t know any better.
“I don’t want to make you angry and unhappy. Shira, I never understood why humans apologize, but now I feel a need to do so. They’re trying to get rid of this feeling of being in the wrong. They’re expressing a wish to undo what they have done, but it is done, and regret is senseless. What can I do to fix this?” It began scraping at the dirt and replanted the roots ripped from the soil. “Please, Shira, tell me what to do, if there’s a way to put back what I’ve spoiled?”
“I doubt if it will live, but we’ll cut it back and try.” She fetched a shovel from the garden closet. “Why did you attack it?”
“It attacked me first, Shira…. That was a thorn?”
“Do you experience pain? Is that possible?”
“I was built with pleasure and pain centres. I surmise that’s how Avram planned to control me and how I am motivated, besides my primary programming for protection, survival and acquiring information.”
“I brought you to experience the rose. What’s left of it.” She sighed and with the clippers with which she had cut back the ancient climber, detached from the pile of lopped-off branches a spray of yellow blossoms.
Yod extended a hand gingerly. It took hold of one rose and deftly plucked it, bringing it towards its face. “It has colour, fragrance and form, just as my memory instructed me. But it also has a curiously pleasant tactile quality. I think you might describe it as … like velvet, perhaps? Am I using a simile correctly?”
“Excellent, Yod.” She caught herself smiling at it. Smiling felt odd; how little she had had to smile at in her recent past.
“However, I have to comment that the velvet analogy is highly imperfect. I can distinguish the individual components of the nap of velvet — I experienced the material in the draperies in the living room of Avram’s flat. In the case of the tactile experience of the rose, the smoothness is unbroken by nap and there is more dampness.”
“Nevertheless, do you recall the Robert Burns poem?”
Yod recited it with a perfect imitation of her inflection.
“Now, what did he mean?”
“He meant that the woman was beautiful, like this flower, and that she smelled of perfume, perhaps.”
“How do you know the rose is beautiful?”
“My base tells me it’s so regarded by humans: that flowers are beautiful, although it seems, too, that humans often disagree about who or what is beautiful and that every era has different opinions. Beauty isn’t a concept I find useful. I don’t understand what it means, except as elegance in design.”
“There’s more implied in the poem. Do you know how long roses last?”
“No.” Yod cocked its head and waited.
“Flowers are mostly creatures of a moment. That rose is already beginning to wilt. If you put its stem in water, it will last a couple of days.”
“Therefore a flower comparison implies short duration.”
“Correct.”
It frowned. “Then it’s a sad poem.”
“Not exactly. But there’s an undertone of mortality. With us there is often an undertone of mortality.”
“I am mortal too, Shira. I can be turned off, decommissioned, destroyed.”
“And you can feel pain, which surprises me. But how fragile are you?”
“I am not fragile at all. Humans are surprisingly fragile, if I understand your specs correctly.”
“Now, the idea of design specifications for humans is metaphorical language, Yod, since we are not engineered or built but rather born.”
“I am trying to understand the bonding created by the birthing process. It’s quite strong?”
“There’s no stronger bond.”
“I can tell from your face that my reference to motherhood upset you.”
“It’s not a topic I can deal with at all objectively, not yet, perhaps never. I’m trying all the time not to think about my son.”
“I want to express sympathy — is that the right phrase? — but I don’t know how to do so without reminding you further of what you want to forget.”
“I’m not about to forget, Yod, but thank you.” Why was she telling a machine about her pain? It was like crying to the house when she was a very little girl and did not understand the house was not alive. We should return to the lab.”
“But the poem you taught me is ambiguous. How do you know he is speaking of the woman? ‘My love is like a red, red rose’ could mean his own feelings for her. They could be what he is praising as beautiful and announcing as transitory.” He raised an eyebrow at her and waited, smiling slightly.
“I never thought of that.” She stopped and stared at Yod. “Frankly, I’d like the poem less if I thought that was what Burns meant. That probably was true of that relationship, the way it is of most, but not a cause for celebration. You changed the subject. We should return.”
“Must we? I’d like to see all of your house. The trees, too, interest me. I’ve seen them from Avram’s windows, but I’ve never been close to them before.” He behaved differently here with her than he had in the lab with Avram. He was a little less jumpy and far more expressive. He had become animated with her ever since they had arrived at the house. “The leaves are different on each of them. Is this … fruit?”
“Those are unripe peaches.”
There was a pause while Yod accessed what a peach was. She was about to warn him as he examined the fruit not to detach it, but she observed then how very precisely and carefully he employed his hands. She was growing used to the slightly perplexed frown of concentration that came over him when he was retrieving some piece of unfamiliar information from his data bases. “Do you have a room here? Gadi has a room in Avram’s flat. Avram has a room also that is only his. In addition, there are common rooms, such as a kitchen, where food is prepared ―”
