            "description": "Introduction\n\nFriends!\n\nChapter 1\n\nA few years ago, the use of AI carried out a revolution in GO. And robots, or rather AI, apparently, our near future will be saturated. And then there are a lot of questions and consequences, which are most interesting to study using the example of exciting stories. I have them.\nSo, everything you wanted to know about the presence of a soul in robots, but were afraid to ask, you can find out in the animated dilogy of Mamoru Oshii, Ghost in the Shell (Kôkaku Kidôtai), 1995  and Mamoru Oshii, Ghost in the Shell 2: Innocence, 2004.\npavelgvozdev.ru/Ghost.jpg\n\npavelgvozdev.ru/Innocence.jpg\n\nEverything you wanted to know about the Turing test, but were afraid to ask, you can learn from Alex Garland's film \"Out of the Machine\" (Alexander Medawar \"Alex\" Garland, Ex Machina, 2014).\npavelgvozdev.ru/ExMachine.jpg\n\nEverything you wanted to know about the upbringing of robots, but were afraid to ask, you can learn from Neill Blomkamp's film \"A Robot named Chappie\" (Neill Blomkamp, Chappie, 2015).\npavelgvozdev.ru/Chappie.jpg\n\nEverything you wanted to know about the evolution of robots, but were afraid to ask, you can learn from Gabe Ibáñez's film \"Autómata\", 2014.\npavelgvozdev.ru/Automata.jpg\n\nGood luck to you, because the future has already begun, but this is a completely different story ...\n\nChapter 2\n\nThis is a saying, not a fairy tale. The fairy tale will be ahead.\n\nChapter 3\n\nGrandfather Frog, who is an official member of the group Gomagic.org at the OGS, holds an unofficial September (2022) tournament Gomagic.org \"Everything you wanted to know about robots, but were afraid to ask.\"\nThere will be no scandals, intrigues and investigations at this tournament. If the films mentioned in Chapter 1 are not enough for you, then read two books: James Rodman Barrat, Our Final Invention: Artificial Intelligence and the End of the Human Era; Stanisław Lem, Summa Technologiae.\nEach participant of this unofficial tournament will receive an unofficial prize - a Chinese book on go in electronic form.\nSomething about the regulations. Please note that each move adds 1 day to the time, but no more than 3 days. The time is suspended for the weekend. This means that you have to make one move a day.\nSoon the tournament will have an author's advertising poster.\n\nChapter 4\n\nBe careful with the AI, good luck, an interesting game and let the strongest win!\n\nWith respect,\n\nGrandfather Frog.",
