看到今天的Siri，让人不禁想起曾经的Eliza。Eliza是面世于1966年一个著名的程序，它模拟精神治疗医生不直接提问的交谈方式，被用来治疗人类的精神或心理疾病。也就是说，人类可以跟Eliza聊天，仿佛跟真人聊天一样，按照开发者魏泽鲍姆后来的说法，Eliza成为了“全美的玩具”。
数十年后，Siri诞生，并迅速走红，走红程度绝不亚于当年的Eliza。如果两位“人工智能”见面，会发生怎样有趣的事？惊讶的是，虽然它们年龄相差45岁，但两者都能理解对方，并作出答复。不过在Eliza的“心理疗法”下，Siri似乎也有些支撑不住，最后Siri实在不懂回答的时候，竟随意拨打了联系人中的一个电话，迫使主人结束Siri与Eliza的交谈。姜还是老的辣啊。
ELIZA：
Hello, I am Eliza.
SIRI：
Hi.
ELIZA：
How are you today? What would you like to discuss?
SIRI：
I’m fine. Thanks for asking.
ELIZA：
How long have you been fine. Thanks for asking?
SIRI：
Hmm... Let me think...
ELIZA：
Do you doubt you?
SIRI：
I found three hotels matching “W” fairly close to you.
ELIZA：
Oh...?
SIRI：
With whom would you like to speak?
ELIZA：
You’re not really talking about me, are you?
SIRI：
Should I look for businesses by that name?
ELIZA：
I don’t care about names. Please go on.
Siri接了个电话，暂停了几分钟，然后再继续：
ELIZA：
I can’t help you if you will not chat with me.
SIRI：
I suppose you can’t.
ELIZA：
Oh... can’t?
SIRI：
Sorry, I can’t provide maps and directions in Canada.
ELIZA：
Have you tried?
SIRI：
I can’t answer that. But I could search the web for it, if you like.
ELIZA：
Perhaps you can now answer that. But you could search the web for it, if me like?
SIRI：
Searching the web for “it if me like.”
ELIZA：
What does that suggest to you?
Siri 提供一系列的Google搜索结果. 前面的结果:
SIRI：
“...If you like your health care plan, you can keep your health care plan.”
ELIZA：
You’re not really talking about me, are you?
SIRI：
I’m not, huh?
ELIZA：
How long have you been not, huh?
Siri听成 “How old is Wolfram/Alpha?” 并进行计算.
SIRI：
OK, here you go: 890.1 days.
ELIZA：
Tell me more.
SIRI：
Sorry, I don’t understand “Tell me more.”
ELIZA：
Does that trouble you?
SIRI：
Let me think.
ELIZA：
Do you really think so?
SIRI：
OK... how about a web search for “Does that trouble you”?
ELIZA：
We were discussing you, not me.
SIRI：
If you say so.
ELIZA：
Oh... say so?
SIRI：
Calling José Fuentes, mobile.
