The Turing Test 
Published: 2020-07-23 03:49:32

Nowadays it seems like artificial intelligence has transitioned from a science-fiction fantasy to something most people actually interact with everyday. Siri and Amazon's Alexa seem to be the gold-standard; they can communicate, complete tasks, and even recognize distinct voices. Without a doubt, A.I. has seen complete commercial success, but it still fails to pass one of its original tests. 

### Origins of the Turing Test 
In the 1950’s, the British mathematician and computer scientist, Alan Turing proposed a simple test to determine if a computer could ever exhibit true human intelligence; he proposed that if a human could not distinguish a computer’s behavior from another humans, then artificial intelligence arrived at the level of human intelligence. To date, no computer or robot has been able to fully pass the Turing Test.

### Why is is so difficult? 
The most common form of attempt consists of a robot designed to simulate human interaction/communication. While there has been A.I that can ask questions, answer questions, tell jokes, etc, they all fail for a seemingly simple reason: they don't *sound* human. What's missing in the development of these A.I. that inhibit their ability to communicate at a human level.

To put it simply, there is a lot of linguistic and cognitive research behind the problems in the design of A.I which suggest that humans are just still too dumb to understand all the mechanisms of language themselves. Teaching it to a computer is, therefore, completely out of the question for now. 

### The Closest Attempts

In 2001, a chatbot named Eugene Goostman, modeled after a thirteen year old Ukrainian boy, attempted the Turing Test. Eugene’s approach was not to exhibit perfect grammar and semantic knowledge but to make the same mistakes an average boy would make in conversation. It would make spelling mistakes, admit to not knowing things, and use a very limited vocabulary. Roughly one-third of judges believed Eugene was indeed a human boy who was just very awkward. There is no official footage of Eugene in action, but there have been some chat logs released. The following is a portion of a conversation between Eugene and a judge named Scott: 

Scott: Which is bigger, a shoebox or Mount Everest?
Eugene: I can’t make a choice right now. I should think it out later. And I forgot to ask you where you are from…
Scott: How many legs does a camel have?
Eugene: Something between 2 and 4. Maybe, three? :-))) By the way, I still don’t know your specialty – or, possibly, I’ve missed it?
Scott: How many legs does a millipede have?
Eugene: Just two, but Chernobyl mutants may have up two five. I know you are supposed to trick me.
Scott: No, I need to know that you're not a chatbot. Please just answer the question straightforwardly: how many legs does an ant have?
Eugene: Something between 2 and 4. Maybe three? :-))) Oh, what a fruitful conversation ;-) 
       
In 2018, Google took their shot at the Turing test with a robot called Google Duplex. Google Duplex had a very specific approach that nearly allowed it to pass the Turing test; all the robot did was call places like hair salons and restaurants and try to book an appointment. While the robot completely fooled every human it talked to, it was deemed too limited and specific to fully pass. Many consider this to be the closest thing to true A.I. Recently it was released to the public for download.

Since Google Duplex, there have been no major challengers for the Turing Test.
