Can machines think? That was the question posed by the great mathematician Alan Turing. Half a century later six computers are about to converse with human interrogators in an experiment that will attempt to prove that the answer is yes.
In the “Turing test” a machine seeks to fool judges into believing that it could be human. The test is performed by conducting a text-based conversation on any subject. If the computer’s responses are indistinguishable from those of a human, it has passed the Turing test and can be said to be “thinking.”
No machine has yet passed the test devised by Turing, the British genius who helped to crack German military codes during World War II. But at 9am this coming Sunday, six computer programs — “artificial conversational entities” — will answer questions posed by human volunteers at the University of Reading, England, in a bid to become the first recognized “thinking” machine. If any program succeeds, it is likely to be hailed as the most significant breakthrough in artificial intelligence since the IBM supercomputer Deep Blue beat world chess champion Garry Kasparov in 1997. It could also raise profound questions about whether a computer has the potential to be “conscious” — and if humans should have the “right” to switch it off.
Professor Kevin Warwick, a cyberneticist at the university, said: “I would say now that machines are conscious, but in a machine-like way, just as you see a bat or a rat is conscious like a bat or rat, which is different from a human. I think the reason Alan Turing set this game up was that maybe to him consciousness was not that important; it’s more the appearance of it, and this test is an important aspect of appearance.”
The six computer programs taking part in the test are called Alice, Brother Jerome, Elbot, Eugene Goostman, Jabberwacky and Ultra Hal. Their designers will be competing for an 18-carat gold medal and US$100,000 offered by the Loebner Prize in Artificial Intelligence.
The test will be carried out by human “interrogators,” each sitting at a computer with a split screen: one half will be operated by an unseen human, the other by a program. The interrogators will then begin separate, simultaneous text-based conversations with both of them on any subjects they choose. After five minutes they will be asked to judge which is which. If they get it wrong, or are not sure, the program will have fooled them. According to Warwick, a program needs only to make 30 percent or more of the interrogators unsure of its identity to be deemed as having passed the test, based on Turing’s own criteria.
Warwick said: “You can be flippant, you can flirt, it can be on anything. I’m sure there will be philosophers who say, ‘OK, it’s passed the test, but it doesn’t understand what it’s doing.’”
One such philosopher is Professor A.C. Grayling of Birkbeck College, University of London. “The test is misguided. Everyone thinks it’s you pitting yourself against a computer and a human, but it’s you pitting yourself against a computer and computer programmer. AI is an exciting subject, but the Turing test is pretty crude.”
Recently the Chinese Nationalist Party (KMT) and its Mini-Me partner in the legislature, the Taiwan People’s Party (TPP), have been arguing that construction of chip fabs in the US by Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) is little more than stripping Taiwan of its assets. For example, KMT Legislative Caucus First Deputy Secretary-General Lin Pei-hsiang (林沛祥) in January said that “This is not ‘reciprocal cooperation’ ... but a substantial hollowing out of our country.” Similarly, former TPP Chair Ko Wen-je (柯文哲) contended it constitutes “selling Taiwan out to the United States.” The two pro-China parties are proposing a bill that
Institutions signalling a fresh beginning and new spirit often adopt new slogans, symbols and marketing materials, and the Chinese Nationalist Party (KMT) is no exception. Cheng Li-wun (鄭麗文), soon after taking office as KMT chair, released a new slogan that plays on the party’s acronym: “Kind Mindfulness Team.” The party recently released a graphic prominently featuring the red, white and blue of the flag with a Chinese slogan “establishing peace, blessings and fortune marching forth” (締造和平,幸福前行). One part of the graphic also features two hands in blue and white grasping olive branches in a stylized shape of Taiwan. Bonus points for
March 9 to March 15 “This land produced no horses,” Qing Dynasty envoy Yu Yung-ho (郁永河) observed when he visited Taiwan in 1697. He didn’t mean that there were no horses at all; it was just difficult to transport them across the sea and raise them in the hot and humid climate. “Although 10,000 soldiers were stationed here, the camps had fewer than 1,000 horses,” Yu added. Starting from the Dutch in the 1600s, each foreign regime brought horses to Taiwan. But they remained rare animals, typically only owned by the government or
“M yeolgong jajangmyeon (anti-communism zhajiangmian, 滅共炸醬麵), let’s all shout together — myeolgong!” a chef at a Chinese restaurant in Dongtan, located about 35km south of Seoul, South Korea, calls out before serving a bowl of Korean-style zhajiangmian —black bean noodles. Diners repeat the phrase before tucking in. This political-themed restaurant, named Myeolgong Banjeom (滅共飯館, “anti-communism restaurant”), is operated by a single person and does not take reservations; therefore long queues form regularly outside, and most customers appear sympathetic to its political theme. Photos of conservative public figures hang on the walls, alongside political slogans and poems written in Chinese characters; South
