OMG Alan Turing is a real person!

lol finally someone who knows how i feel :-P I think I've learned more from this thread than I have from taking half a year of C++ and half a year of Java.

--- Quote from: Ozymandias ---Nothing has ever truly passed the Turing test.

A few chat bot have fooled some rather simply minded and unexpecting people, but nothing has ever fooled 30% of judges during a 5-minute test, like Turing proposed.

Never even came close.

Actually, they have. Roger Schank designed a program that succeeded in understanding simple stories. Roger Penrose provides an example in The Emperor's New Mind, pg. 18.

Basically, a computer is fed a story such as, "A man went into a store and ordered a hamburger, enjoyed it, paid the bill and left." The computer is asked whether the man ate the hamburger. It would then pass out yes or no based on the story. In essence, this machine passed a Turing Test.

Of course, the counterargument is that the machine had no concept of eating, or of hamburgers, but rather that the computer doesn't strictly need to understand these concepts in order to process yes or no.

Imagine if the story was written in Chinese. You could have an algorithm that if you saw a character that looked like <insert chinese character here>, you would say yes. Thus, you understood the Chinese story without understanding it at all.

QHD:
That's hardly passing the Turing Test - it's just being able to answer questions that involve reaching conclusions from certain premises, something computers have always been able to do fairly well. Whoever said nothing has ever passed the Turing Test is right - it is not enough that a machine could "understand" stories - it must understand sarcasm, irony, humour, etc... it would take a thousand code monkeys with a thousand machines a thousand years to make a program that truly passed the Turing test, I'd say.

Even then, the Chinese room argument still stands - even if able to pass the Turing test the computer would be doing nothing more than manipulating symbols. In fact, it may be for precisely this reason that no machine ever will.

In case I sounded like I know what I'm talking about at any stage, I will just add: I am probably very wrong because I suck.

Nope! That's just simple deduction, every CS student learns to code such stuff in his 3 year (at least over here).
The turing test involves a machine and two humans (one judge). The judge talks to the machine and the other human about any topic on a text only channel. Only if the judge can't distinguish the other human from the machine the machine passed the test.
NOTE: The test, as suggested by Turing, is not limited to a special topic (that means free conversation!) or a special amount of time!!!
Up to now NO machine/program passed the test.

Yeah, but you win on teh name. It shows that you're the more hardcore fan. Great book by the way. As is Snow Crash. As is Quickslilver.
