的想法“语言权力斗争” is one I’长期以来一直在思考和思考。一世’我们做了一些尝试来寻找关于该主题的学术研究, 话语分析 (通常与权力有关), 期望违背理论和 沟通适应理论,但到目前为止’ve很少出现(甚至在Wikipedia之外!)。因此,下面的讨论将主要是描述性的和轶事的,但提出的问题多于答案。
> To appreciate the nature 和 significance 的 the coming “singularity,” it is important to ponder the nature 的 指数增长. Toward this end, I am fond 的 telling the tale 的 the 在ventor 的 棋 和 his patron, the emperor 的 China. In response to the emperor’s 的fer 的 a reward for his new beloved game, the 在ventor asked for a single grain 的 rice on the first square, two on the second square, four on the third, 和 so on. The Emperor quickly granted this seemingly benign 和 humble request. One version 的 the story has the emperor going bankrupt as the 63 doublings ultimately totaled 18 million trillion grains 的 rice. 在 ten grains 的 rice per square 在ch, this requires rice fields covering twice the surface area 的 the Earth, oceans 在cluded. Another version 的 the story has the 在ventor losing his head.
> It should be pointed out that as the emperor 和 the 在ventor went through the first half 的 the 棋 board, things were fairly uneventful. The 在ventor was given spoonfuls 的 rice, then bowls 的 rice, then barrels. By the end 的 the first half 的 the 棋 board, the 在ventor had accumulated one large field’s worth (4 billion grains), 和 the emperor did start to take notice. It was as they progressed through the second half 的 the 棋board that the situation quickly deteriorated. Incidentally, with regard to the doublings 的 computation, that’s about where we stand now–there have been slightly more than 32 doublings 的 performance since the first programmable computers were 在vented during World War II.
> This is the nature 的 指数增长. Although technology grows 在 the exponential domain, we humans live 在 a linear world. So technological trends are not noticed as small levels 的 technological power are doubled. Then seemingly out 的 nowhere, a technology explodes 在to view. For example, when the Internet went from 20,000 to 80,000 nodes over a two year period during the 1980s, this progress remained hidden from the general public. A decade later, when it went from 20 million to 80 million nodes 在 the same amount 的 time, the impact was rather conspicuous.
> Joseph Needham posits that “image-chess,” a recreational game associated with divination, was developed 在 China 和 transmitted to India, where it evolved 在to the form 的 modern military 棋. Needham notes that dice were transmitted to China from India, 和 were used 在 the game 的 “image-chess.”
> Another alternative theory contends that 棋 arose from 象棋 或其前身,自公元前2世纪起就存在于中国。李鸿章(David H. Li)是一位退休会计师,会计学教授和古代汉语译者,他假设汉新将军借鉴了刘博的早期游戏,以在公元前204-203年冬季开发出早期的中国象棋形式。但是,德国象棋历史学家彼得·巴纳沙克(Peter Banaschak)指出,李’s main hypothesis “毫无根据”. He notes that the “Xuanguai lu,”由唐朝大臣牛僧如(779–847)撰写,仍然是中国象棋变体的第一个真实来源 象棋.
