Inhaltsangabe

A playful, profound book that is not only a testament to one man's efforts to be deemed more human than a computer, but also a rollicking exploration of what it means to be human in the first place.

“Terrific. ... Art and science meet an engaged mind and the friction produces real fire.” —The New Yorker

Each year, the AI community convenes to administer the famous (and famously controversial) Turing test, pitting sophisticated software programs against humans to determine if a computer can “think.” The machine that most often fools the judges wins the Most Human Computer Award. But there is also a prize, strange and intriguing, for the “Most Human Human.”

 1. Introduction: The Most Human Human

I wake up five thousand miles from home in a hotel room with no shower: for the first time in fifteen years, I take a bath. I eat, as is traditional, some slightly ominous-looking tomatoes, some baked beans, and four halves of white toast that come on a tiny metal rack, shelved vertically, like books. Then I step out into the salty air and walk the coastline of the country that invented my language, despite my not being able to understand a good portion of the signs I pass on my way—let agreed, one says, prominently, in large print, and it means nothing to me.

I pause, and stare dumbly at the sea for a moment, parsing and reparsing the sign in my head. Normally these kinds of linguistic curiosities and cultural gaps interest and intrigue me; today, though, they are mostly a cause for concern. In the next two hours I will sit down at a computer and have a series of five- minute instant- message chats with several strangers. At the other end of these chats will be a psychologist, a linguist, a computer scientist, and the host of a popu­lar British technology show. Together they form a judging panel, and my goal in these conversations is one of the strangest things I’ve ever been asked to do.

I must convince them that I’m human. Fortunately, I am human; unfortunately, it’s not clear how much that will help.
The Turing Test

Each year, the artificial intelligence (AI) community convenes for the field’s most anticipated and controversial annual event—a competi­tion called the Turing test. The test is named for British mathemati­cian Alan Turing, one of the founders of computer science, who in 1950 attempted to answer one of the field’s earliest questions: Can machines think? That is, would it ever be possible to construct a com­puter so sophisticated that it could actually be said to be thinking, to be intelligent, to have a mind? And if indeed there were, someday, such a machine: How would we know?
Instead of debating this question on purely theoretical grounds, Turing proposed an experiment. A panel of judges poses questions by computer terminal to a pair of unseen correspondents, one a human “confederate,” the other a computer program, and attempts to discern which is which. There are no restrictions on what can be said: the dialogue can range from small talk to the facts of the world (e.g., how many legs ants have, what country Paris is in) to celebrity gossip and heavy-duty philosophy—the whole gamut of human conversation. Turing predicted that by the year 2000, computers would be able to fool 30 percent of human judges after five minutes of conversation, and that as a result “one will be able to speak of machines thinking without expecting to be contradicted.”

Turing’s prediction has not come to pass; at the 2008 contest, how­ever, held in Reading, England, the top program came up shy of that mark by just a single vote. The 2009 test in Brighton could be the decisive one.
And I am participating in it, as one of four human confederates going  head-to-head  (head-to-motherboard?) against the top AI pro­grams. In each of several rounds, I, along with the other confederates, will be paired off with an AI program and a  judge—and will have the task of convincing the latter that I am, in fact, human.

The judge will talk to one of us for five minutes, then the other, and then has ten minutes to reflect and make his choice about which one of us he believes is the human. Judges will also note, on a slid­ing scale, their confidence in this  judgment—this is used in part as a tie-breaking measure. The program that receives the highest share of votes and confidence from the judges each year (regardless of whether it “passes the Turing test” by fooling 30 percent of them) is awarded the “Most Human Computer” title. It is this title that the research teams are all gunning for, the one that the money awards, the one with which the organizers and spectators are principally concerned. But there is also, intriguingly, another title, one given to the confeder­ate who elicited the greatest number of votes and greatest confi dence from the judges: the “Most Human Human” award.

One of the first winners, in 1994, was Wired columnist Charles Platt. How’d he do it? By “being moody, irritable, and obnoxious,” he says—which strikes me as not only hilarious and bleak but also, in some deeper sense, a call to arms: How, in fact, do we be the most human humans we can  be— not only under the constraints of the test, but in life?
Joining the Confederacy

The sponsor and organizer of the Turing test (this particular incarna­tion of which is known as the Loebner Prize) is a colorful and some­what curious figure: plastic  roll-up portable disco dance fl oor baron Hugh Loebner. When asked his motives for backing and orchestrat­ing this annual Turing test, Loebner cites laziness, of all things: his utopian future, apparently, is one in which unemployment rates are nearly 100 percent and virtually all of human endeavor and industry is outsourced to intelligent machines. I must say, this vision of the future makes me feel little but despair, and I have my own, quite different ideas about what an AI-populated world would look like and reasons for participating in the test. But in any event, the central question of how computers are reshaping our sense of self, and what the ramifications of that process will be, is clearly the crucial one.

Not entirely sure how to go about becoming a confederate, I started at the top: by trying to reach Hugh Loebner himself. I quickly found his website, where, amid a fairly inscrutable amalgam of mate­rial about  crowd-control stanchions,1 sex- work activism,2 and a scan­dal involving the composition of Olympic medals,3 I was able to fi nd information on his eponymous prize, along with his email address. He replied by giving me the name of Philip Jackson, a professor at the University of Surrey, who is the one in charge of the logistics for this year’s Loebner Prize contest in Brighton, where it will be held under the auspices of the 2009 Interspeech conference on speech and com­munication science.

I was able to get in touch via Skype with Professor Jackson, a young, smart guy with the distinct brand of harried enthusiasm that characterizes an overworked but  fresh-faced academic. That and his charming Briticisms, like pronouncing “skeletal” so it’d rhyme with “a beetle”: I liked him immediately. He asked me about myself, and I explained that I’m a nonfi ction writer of science and philosophy, specifically of the ways in which science and philosophy intersect with daily life, and that I’m fasci­nated by the idea of the Turing test and of the “Most Human Human.” For one, there’s a romantic notion as a confederate of defending the human race, à la Garry Kasparov vs. Deep Blue—and soon, Ken. 

 
Jennings of Jeopardy! fame vs. the latest IBM system, Watson. (The mind also leaps to other, more Terminator– and The Matrix–type fantasies, although the Turing test promises to involve signifi cantly fewer machine guns.) When I read that the machines came up shy of passing the 2008 test by just one single vote, and realized that 2009 might be the year they finally cross the threshold, a steely voice inside me rose up seemingly out of...
