Technology–A Double-edged Sword
In the past, technological advancement was generally held to be synonymous with progress, and progress to be synonymous with absolute good. People thought of technology as a solution to problems, not a creator of them. As we took each step forward, technologically speaking, we assumed that we were leaving old difficulties behind and advancing into a new and more pleasant future. This was only partially true. For us technological advancement did solve old problems, it also created new ones. These problems are of various types, each having different implications and requiring different degrees of human decision. One set of problems can be readily identified by looking around. These problems concern the “pollution” of our environment by technology as a result of sudden upsets and imbalances in the physical, economic and social equilibrium. The most obvious aspects of these are the general pollution of our physical environment and the destruction of irreplaceable natural resources.Not so obvious as these, but just as painfully significant to some, are the effacement and displacement of jobs which overnight often create large groups of jobless citizens. Can technology be used to undo what it has done, replace what it has destroyed or substitute what it has caused to disappear? No one knows. Many of us wonder whether all of the sources of pollution have yet been identified, whether they are being arrested and whether they will be prevented from recurring. Another set of problems relate to what technological advancement has done to the quality of life. An improved life has not been, unfortunately, either the goal or the chief beneficiary of technological change. Too much has happened too fast. In contrast, in the past, things changed slowly enough to accommodate gradual change. People could be aware of it and adjusted to it, and perhaps they could even change it. In the modern world, we must make rapid decisions today, or tomorrow wemay find a whole new world built up. Presumably the most significant and potentially explosive issues, however, are those related to methods of human manipulation and control. There is also the new horizon of genetic analysis, manipulation and correction. And there is now the possibility of creating a living substance and decoding and generating a complete organism from the information found within a cell.This is no longer a daydream. Some consider these possibilities visions, others nightmares. It is true that incredible powers are now within our hands,or at least within our reach, and the question no longer is “Can we do it?” but “How soon can we do it?” Our lives have been and are being changed drastically. The point is to take control of technology or to be driven by it.

科技–一把双刃剑 在过去,一般都认为是科技发展进步的同义语,是进步的同义词绝对好. 人们认为,作为解决问题的技术,而不是制造问题. 当我们把每一步,在技术上来说,我们认为,我们离开了旧困境,迈向新的、更加美好的未来. 这只是一部分. 技术进步也为解决中美老问题,也创造了一些新的问题. 这些问题的各类问题各有不同,需要不同程度的人决定. 一套可以随时提出问题,环顾. 这些问题涉及”污染”对环境造成的技术和不平衡突然打破了自然、经济和社会的平衡. 最明显的问题是一般污染环境和破坏自然resources.not不可替代那么明显,因为这些,而是因为一些重大痛苦,是毁灭,流离失所的职位 夜晚常常造成大批失业公民. 技术可以用来消除所做的事,将它摧毁或取代它使消失? 没有人知道. 许多美国怀疑所有的污染源尚未确定是否被抓,是否会出现阻止. 另一组问题是什么,做科技进步的生活质量. 生活未获改善,不幸的是,无论是目标还是技术变革的主要受益者. 事情太多太快. 与此相反,过去的事情慢慢改变,足以容纳渐变. 人们知道这件事,可以调整的话,或许更可以改变它. 在当今的世界上,我们必须迅速决定,今天或明天,我们 会发现建立一个全新的世界. 大概是最重要的问题和潜在的爆炸性,但涉及操纵和控制人的方法 . 还有新地平线基因分析、操纵和纠正. 现在,可能造成生活内容,并形成一个完整的解密,从机体内部的资料发现cell.this不再是空想. 可能有些人认为这些看法,有些恶梦. 确实难以置信在我们手中的权力是现在,或者至少伸手可及,这个问题已不再是”能做到这一点?” 但”我们何时才能做到这一点?” 我们的生活已经和正在发生巨大变化. 这一点是必须掌握的技术和驾驶.
