Dear X
  somewhere,  sometime will be able to read it. 或许，某一个人将会在某一个地方，在某一个时间节点读到这封信，也可能只有机器人和电脑会读到这封信，并因此而大笑。
 At first,  But they were soon everywhere.  Some of the earliest thinking machines were used to control the temperature.  When it was too cold,  they turned up the heat and when it was too warm,  they turned on the air conditioner.  This doesn’t sound too dangerous,  but once people got used to have temperatures controlled and then lights being controlled,  fire sprinklers（喷头）and many household appliances.  It was great! People had more free time! Well,  only rich people had more free time. 但实际上，只有富人才会因此而有更多的自由时间。
 一时之间，这个世界被划分为两种阶层，一种是拥有科技获得感的人，另一种则是无法享受科技所带来的红利的人。
 Of course,  it was only natural that the technology have-nots would want more.  Soon,  they started stealing from and rebelling against humans with technology.  People installed security systems in their homes and business.  Computers used video cameras to watch everything and everyone. 不久后，他们就开始向科技拥有者偷窃，反抗科技拥有者。
 人们在家里和公司里安装安保系统。
 计算机用视频录像机来监视着人们的一言一行。
 当这种安保水平退化，人们开始考虑机器人进行安全保障。
 While all this was going on,  two other lines of research were being pursued in artificial intelligence laboratories.  One area of interest was robots that could recreate themselves.  The plan was to send them planet,  like Mars,  No one ever thought of what would happen if they escaped their labs on Earth.  The other research direction was in parallel processing. 这个计划就是将克隆机器人送往像火星这样的行星上，然后让其为未来的移民建造城市。
 但却没有人想过如果它们逃离地球上实验室，将会发生什么。
 另一个研究方向是关于计算机的并行处理能力。
 科学家们意识到，与其仅仅制造一台超级计算机，还不如将几台普通计算机联网在一起，这样也能实现同样的思考方式。
 不久后，计算机联网正彼此交互，共同解决问题。
 One of the real problems was the whole idea of remote control. 一个现实问题就是远程操控。
 要是在你睡觉时，你的房间温度自动降低了，烤箱自己启动了，浴缸的水自己溢出来了，该怎么办？
 当我的旧收音机还能用的时候，最初的新闻报道经常谴责计算机黑客传播计算机病毒，使机器人和计算机尽其所能地杀死人类，最先是中断食物、水、电和燃料的供应。
 我不知道这是否真实发生。
  I left the city,  moved into a cave high in the mountains and started growing my own food and making everything I need by hand.  Eventually,  of course,  And what did they need humans for?
