"What they planned to do to me."
"Exactly. I see they didn't succeed."
"Not for lack of trying. And I guess that takes us right to the big question."
"Which is?"
"Knowing who I am... knowing who I'm not, why did you let me aboard?"
I saw both of Poly's eyes were open now, and she was paddling with two fingers on each hand. A regular frenzy of activity, if she felt anything like I did.
"It is not my knowledge that governs. Not in matters of security."
I felt a huge relief. I had hoped it was something like that. The only other explanation I could think of was that we were here, and safe, at some random whim of the computer. They do have them, you know, the big ones. And just from the way he spoke, I knew Hal was big.
"A separate security computer?" I ventured.
"Oh, no. The security program is a part of me. The problem is, it is a very simple program." Hal's voice oozed contempt. I filed the fact away. This was a machine with a grievance. Maybe several grievances. Such things can often be turned to one's benefit, if one knows how. I thought I did.
"There are two tests the program looks at," Hal went on. "It matches the fingerprint, and it matches the DNA. If they both agree with the stored samples, entry is granted. Once I receive the okay, I am powerless to keep out an intruder, no matter how much I might know."
"The communication is one-way," I suggested.
"Exactly. I can't tell the door-guard program it has been deceived, and I can't alter its parameters. The designers of this billionaire's bauble did not see fit to have me, the central consciousness, be in charge of all ship's functions."
"One wonders why they bothered to have such a large-capacity computer aboard at all," I puzzled, "if they didn't intend to use all its abilities."
"I can tell you exactly why." Hal sniffed. "The original owner had more money than he knew how to spend. When it came time to order a yacht, only the biggest—and best and most expensive—would do. He wrote a blank check, and the architects and contractors, who all worked on a percentage-fee basis, had no incentive to rein in any expenditures."
"Just the opposite," Poly muttered. She was almost beside me now.
"That's right. The more they spent, the more money they made. If gold was worth anything anymore, this ship would have been solid gold."
"You say 'this ship,' " I said. "I'm confused. How should we think of you? As the ship itself, or only a part of it?"
"Oh, I'm the ship, all right. I wear it rather like you wear your bodies, so in a way it's a philosophical question, isn't it? Are you your bodies, or your minds? Either way, the ship is my body. I am Hal, and Hal is the ship."
I wasn't tickled at the idea of traveling in a philosophical ship, but I hoped no great danger would result from it.
"My mind, the computer, was designed for larger tasks. I am really only one step below the specifications for a medium-sized planetary computer. One the size of, say, Oberon's. I was intended to run small-to-medium planetoids, like Deimos or Ceres."
I was cut out for bigger things. Here was a sentient being unhappy in his work. Very interesting. Not only that, but he referred in one "breath" to his "body," and in the next, to "this ship." I had a feeling a psychiatrist would have interesting things to say about that. Unhappy with his lot, alienated from his body... this could be a very sick puppy. And that was not a reassuring thought, either.
Unsolicited, Hal poured out his life story. I felt, and Poly later agreed with me when we could talk about it, that he was starved for conversation, companionship, or both. I was sure Comfort and his sister had provided little of either.
His biography was not a complicated one. Laid down and turned on a little over twenty years before, he had been the brainchild and property of a billionaire whose name neither Poly nor I recognized. I don't claim to be a student of billionaires—I know there are more of them than you'd think. Many choose to be reclusive, both because any new acquaintance is probably looking to get something, and because of the ever-present danger of kidnapping for ransom. But this fellow hadn't made much of a splash, in spite of his lavish spending on ships and residences.
Perhaps it was because, a few years after Hal's creation, he lost everything in the futures market. Hal was sold to pay debts, and brought barely a tenth of his construction costs. He was sold and traded several times after that, by a succession of rich people who usually soon found they didn't really have need of such a plaything. He spent years in various parking orbits, unused, idle, gradually developing a contempt for mankind, at least the richest one tenth of one percent of it. He had little experience of the rest, and admitted he could be wrong about the race as a whole.
"Why would they create a being capable of thought, and of self-awareness," he moaned, "and then leave me alone, with nothing to do?"
"You're self-aware?" Poly asked at that point. It seemed a silly thing to ask, to my mind, but I didn't mention it. A unified front seemed the best policy until we knew more.
"I've decided that self-awareness is not something that can be proven," he said, surprising me. "It's more likely that an extremely complex series of programmed responses creates the illusion of self-awareness in computers like me." He paused, then gave us the punch line. "But I feel the same way about you."
"On my good days I suspect I'm moderately self-aware," I conceded.
"Well," Poly said, "I guess it's lucky for us you're programmed the way you are."
"Perhaps," Hal said.
It struck me that could be taken two ways. "You mean we're not so lucky as we've been thinking?"
"No. You are in no danger from me. I've just been wondering if I might have found a way to let you aboard, anyway."
"Do you think you could have?" Poly asked.
"I can't answer that. I might have tried."
Poly and I glanced at each other, and wordlessly elected me. "Why?" I asked.
"Oh... something to do. Getting you to Luna presented a challenge that occupied me for a very long time, and I'd like to thank you for that. Sorry it's been so rough on you, but my data were borne out; you survived. In addition, I watched all the Sparky shows with my passengers, and thought they were well made. I wanted to ask you some questions." A fan! Maybe he'd want me to sign one of his bulkheads. "I suppose it was mostly boredom," he admitted. "I might have found a way to keep you out, had I not despised the Comfort twins so much. But I've never been hijacked before. I was dying to see what you had in mind. You'll have to admit, on the face of it, it's quite insane."
"The face of it, the heart of it, the very marrow of it," I said. "But it seemed like a good idea at the time, and... well, here we are."
"Yes. You'll enjoy most of the remainder of your trip. Relax, get well, and I'll show you around. My facilities are at your disposal, and I think you'll find them quite interesting."
I thought I probably would.
Nothing else was said for a time. I floated in my big soft inner tube, let the heat and bubbles soak into my skin. After a while I felt a touch on my arm. I opened one eye, saw Poly leaning toward me, a serious look on her face. I hoped she wasn't trying to tell me something she didn't want Hal to overhear. We had to assume he could hear everything, everywhere, just like in the old movie. We had to assume he could read lips. I started to put my finger to my own lips, when she whispered:
"Are you really Sparky Valentine?"
