中文简介:
如果你认为人类现在生活在一个地球工程的星球上,那么我们对未来的责任是什么呢?在讨论如何处理地球系统之前,布拉德艾伦比要求我们仔细考虑人类系统的复杂性,特别是我们倾向于产生比我们意识到的更多的复杂性,并假设“我们有一个合理的处理方向......并且可以因此,谈论(未来)有一定程度的合理性。“在一篇由Stewart Brand,William Gibson和Vishnu引用的演讲中,Allenby在讨论全球问题的解决方案时汇集了一些”我们应该关心的“趋势。他指出,正如铁路以意想不到的方式改变了美国文化和自我认知,技术的综合影响也是如此。纳米技术,机器人技术,生物技术,信息和通信技术都在同时发生变化,“所以我们可以预测100年的预测是可笑的。”艾伦比还指出,为了我们的危险,我们将自然系统整合到人类系统,将公众关注的问题转交给商业利益,未能为“复杂的适应性系统”建立一个管理的道德结构,所有这一切都在冷战结束时破坏了全球权力关系的稳定.Allenby担心我们是例如,在我们的城市基础设施中建立信息结构,利用人类作为“设计空间”。尽管精心设计的计算机交易系统,但不要忘记全球股票市场是如何崩溃的,他提醒我们。我们如何以一种不伤害的方式接近地球系统工程,更不用说让事情变得更好了?艾伦比建议的一些原则是:“只在必要时进行干预并在必要的范围内进行干预;”在实施之前对复杂系统进行建模,并尽可能进行渐进式和可逆性变更;承认作为气候辩论基础的社会工程议程,以及科学分析与价值观之间的相互作用;并让各方参与讨论,“不仅是与科学家坐在一起的工程师,还有现代英国评论家。”
课程简介: If you take as a given that humans now live on a geoengineered planet, then what is our responsibility for the future? Before discussing how to deal with Earth systems, Brad Allenby asks that we think carefully about the complexity of human systems, especially our tendency to generate far more complexity than we realize, and to assume “that we have a reasonable handle going forward…and can therefore talk about (the future) with some degree of rationality.” In a talk that kicks off with quotes from Stewart Brand, William Gibson and Vishnu, Allenby pulls together some trends “we should care about” when discussing solutions for global issues. He notes that just as railroads changed American culture and self-perception in unexpected ways, so will the integrated impact of technology. Nanotechnology, robotics, biotechnology, information and communication technology are all changing at the same time, “so the idea that we can make projections out 100 years is laughable.” Allenby also notes that, to our peril, we’re integrating natural systems into human systems, handing off what had been public concerns to commercial interests, failing to develop a governing ethical structure for “complex adaptive systems,” all at a time when the end of the Cold War has destabilized global power relationships. Allenby worries that we are dabbling in systems management well over our heads, building information structures into our cities’ infrastructure, for instance, and utilizing humans as “design spaces.” Don’t forget how the global stock market crashed, in spite of carefully designed computer trading systems, he reminds us. How can we approach earth systems engineering in a way so as to do no harm, much less leave things better off? Some principles Allenby recommends: “Only intervene when necessary and to the extent required;” model complicated systems before implementing them, and whenever possible, make incremental and reversible change; acknowledge the social engineering agendas that underlie the climate debate, and the interplay between scientific analysis and values; and bring all parties to the discussion, “not just engineers sitting with scientists, but with post-modern English critics.”
