Zima poured himself a glass of the red wine, but instead of drinking it he merely sniffed the bouquet.
"Yes."
"But there isn't anything natural about being alive a thousand years after I was born," I said. "My organic memory reached saturation point about seven hundred years ago. My head's like a house with too much furniture. Move something in, you have to move something out."
"Let's go back to the wine for a moment," Zima said. "Normally, you'd have relied on the advice of the AM, wouldn't you?"
I shrugged. "Yes."
"Would the AM always suggest one of the two possibilities? Always red wine, or always white wine, for instance?"
"It's not that simplistic," I said. "If I had a strong preference for one over the other, then, yes, the AM would always recommend one wine over the other. But I don't. I like red wine sometimes and white wine other times. Sometimes I don't want any kind of wine." I hoped my frustration wasn't obvious. But after the elaborate charade with the blue card, the robot and the conveyor, the last thing I wanted to be discussing with Zima was my own imperfect recall.
"Then it's random?" he asked. "The AM would have been just as likely to say red as white?"
"No, it's not like that either. The AM's been following me around for hundreds of years. It's seen me drink wine a few hundred thousand times, under a few hundred thousand different circumstances. It knows, with a high degree of reliability, what my best choice of wine would be given any set of parameters."
齐玛给自己倒了一杯红酒，当然他不会喝的，只是闻了闻酒香。“是的。”
“可是我已经活了一千年了，这本身就不自然啊。”我说，“我的机体觉记忆在七百年前就已经到了饱和点，我的脑袋就像一个放了太多家具的房子。想要搬进去一些东西，你就必须先把一些东西搬出来。”“我们还是先回到酒的问题上。”齐玛说。“通常情况下，你必须依赖备忘录助手的建议，对不对？”
我耸耸肩说：“是的，”
“备忘录助手是不是总是选择两种可能性中的特定一种？比如说总是选红葡萄酒，或者总是选白葡萄酒？”
“不是这么简单化。”我说，“如果我对其中一种酒的偏好更强烈，那么备忘录助手肯定会一直推荐我这种酒。但是我对葡萄酒并没有偏好。有时我喜欢红葡萄酒，有时我又喜欢白葡萄酒。还有的时候，两种酒我都不想要。”我希望自己的挫败感不要那么明显。除了谈谈蓝色卡片、雇佣机器人以及运输机这一系列精心策划的谜语，我最不想和齐玛谈论的就是我自己并不完整的记忆。
“那么就是随机选择喽？”，他问道。“备忘录助手会不会就这么随便选择红葡萄酒或者白葡萄酒呢？”
“不是，也不是这样的。备忘录助手已经跟了我几百年了。它已经看见我在成千上万种不同的场合，喝了成千上万次葡萄酒。它知道根据最高的可靠程度，给出一系列参数，然后计算出什么才是我最好的选择。”
