artificial intelligence that can hide from humans. Last year, Google introduced its intelligent wizard-Duplex at its conference for developers. Able to take the appointment to the place of its user, he was impressed, and a little worried, observers with his voice "so human". But if it looks similar as to that of a human, it is because it is sometimes a real person. An article in the New York Times reveals that employees working in call centres can make these reservations. Google has told the us newspaper that about 25% of the calls Duplex) are passed by humans. In addition, approximately 15% of those launched by the intelligent assistant are supported by a real person at a given time.

The company explained that it was sometimes necessary that a human be involved in the conversation, especially when it is not certain that the restaurant takes reservations, or that the service user is not a spammer (person who passes unwanted calls in large numbers). Google also indicates that it is still appeal to humans in order to obtain data to "train" its artificial intelligence, and thus gradually reduce the need of human involvement.

The robot of Google is, in theory, be able to deceive a human. It has been programmed to voluntarily add errors typically human in the conversation. When Duplex is called a restaurant in the name of journalists in the New York Times , for example, her speech is marked by pauses and "hums". In addition, it is able to respond in a coherent manner even when he does not know the answer to a question. When the manager of the restaurant asks him if children will be present, he said, "I reserve in fact for a customer, so I'm not sure".

The artificial intelligence of Google to work through what are called neural networks, is a technology imitating the functioning of the human brain. It allows a program to manage a very large number of data, creating connections between its "neurons", in order to respond to queries in a consistent manner. It is through this technology that the ability of a machine to recognize words, understand how they are used and to generate the word by itself, has improved. Nevertheless, we tend to forget that behind the artificial intelligence is a hidden expertise and human. Many experts are now examining the "digital labor", these new jobs, often hidden, where people are paid to annotate images, sort data, or cause the algorithms to improve their performance. Google Duplex is a new example.
