<<迷失>>中那一团黑烟是什么

基地自动化工作系统
主脑是巨型计算机，操纵数以亿计的纳米机器人。纳米机器人能够自我修复，堆积在一起看起来如同黑烟，可以自由变形，甚至通过巨型计算机的分析模范人的外貌。
它们起初的职能是保护基地和进行基地试验。其后系统故障，极有可能产生人工智能，其行为愈发诡异，甚至威胁工作人员的生命。
在工作人员撤出该岛基地后，自动进行试验，并且试验手段越来越偏激……最终结果必将危害全球。

MC 克来顿的小说中是这样描写黑雾的。

In the Nevada desert, an experiment has gone horribly wrong. A cloud of nanoparticles -- micro-robots -- has escaped from the laboratory. This cloud is self-sustaining and self-reproducing. It is intelligent and learns from experience. For all practical purposes, it is alive. It has been programmed as a predator. It is evolving swiftly, becoming more deadly with each passing hour. Every attempt to destroy it has failed. And we are the prey.
