电子世界争霸战

坦白讲，由于对电脑和信息技术的专业知识基本为零，我感觉自己无法对这部影片提出什么看法。虽然无知但我大抵猜测到这部影片在技术上一定有划时代的领先创造。我还猜测这部影片，经过时间的积淀，一定有一定数量的超级粉丝。 文科生退回到文科生的小天地，不谈数字技术，谈谈思想。但是思想似乎也不太好说，唯一能说的也只能是降维到：好人和坏人打架，最后好人赢了这个最肤浅的层面了。因为看的是无字幕版，故事似乎大体上是讲一个好人（在虚拟世界里化身为好程序）战胜坏人（坏程序）的故事，坏人很强大，好人历经艰辛终于打败了坏人。此外影片似乎还讲述在现实与虚拟的两个时空里，现实的人与虚拟的人是共生共存的。 文化知识界的鄙视链里通常会鄙视那些形式大于内容的东西，这部影片形式出挑不知道是福是祸。一部影片对于文化知识分子来说最重要的是展现作者对一个时代的思考，对这个时代生活方式的描绘。对比于普通人所熟悉的80年代初期，数字世界的入侵还远未到来，这部片子无疑诞生的有点早。影片里的世界超出了普通人所能想象的未来世界。 “前卫”这个词我已经很久没有想起过了，最后一次听人用它好像是在上个世纪末。今天还有什么东西我们会认为它是超前于时代呢，前卫这个词似乎已经彻底消失在今天这个科技日新月异，任何新奇玩意在一天之后就会被大众厌弃的时代了。一切都旧的那么快，新技术不断破浪而来。但对于这部影片的评价却无法回避“前卫”这个古董词汇。这个词语的重新使用也让我再次温故了新鲜事物带来的刺激感。很奇怪，似乎，我的感官并没有随着不断的科技创新而进化的更加丰富，反而是迟钝了许多。我不知道这种迟钝是人类机体的自我保护，还是为未来世界的优胜略汰埋下伏笔。 电子世界侵入了人类的日常生活，虚拟的，触摸不到，光电四射，看似严谨强大却很容易被更新的技术突破，数字技术以越来越复杂的方式将人类逐渐围困，那是一个越来越危险而且缺乏质感的世界。人类作为生命体的短板不断暴露，在我们不断将数字技术作为自己肢体的外延之后，也许终有一天会被彻底取代。

凯文·弗林flynn（杰夫·布里吉斯 Jeff Bridges 饰）是个天才程序员，然而曾经开发的数款游戏软件被前同事盗取，同事也因此成了公司高层，自己则被解雇。这家公司的主控制程序越来越不服从人类的控制，随意将其他程序关押起来，并强迫它们不断地进行各种各样的死亡竞技游戏，野心不断膨胀主控制程序甚至企图控制全人类。公司的工程师艾伦设计了一个针对它的监控程序tron，而这个TRON也被困在了主控程序设计的训练游戏里。艾伦求助于凯文，凯文也想证实那些游戏自己的作品，于是试图进入主控制程序，不料主控制程序察觉了凯文的动作，通过分子扫描将他吸进程序空间变成了程序并关押起来。flynn和程序tron、ram、yori合力毁灭了主控程序，虚拟世界恢复了正常。 赛博空间中角斗场飞盘大战、极光彩带高速赛车、坦克和守护者追击拍得挺不错的。程序居然也分男女，还有感情，还会KISS。 《电子世界争霸战》是史上第一部赛博空间（cyberspace）题材电影，赛博空间即为计算机中的虚拟空间。 1982年Disney公司的作品，个人电脑还未真正进入家庭，画面和现在不能比，但它的概念和技术都是超前的。2007年，美国视效协会（VES）评选出了历史上最具影响力的50部特效电影，本片排在星球大战、银翼杀手、2001太空漫游、黑客帝国、侏罗纪公园之后，位列第六。美国电脑图形学会将这部电影视为电脑图形的里程碑、分水岭，认为它开创了CG电影时代。

这是一个花里胡哨地解决专利剽窃问题的故事:)另外也是电子游戏世界以及对抗AI的主题。

电影出现了大部分续作沿用的设定，激光传送、光碟、光轮摩托、光束缆车、军事飞船等等；甚至Kevin的 “超能力”这点也继承了，双手挥一挥就能隔空移物，一开始我感觉很扯，但后来觉得这是在说明Kevin是这个世界的创造主吧。毕竟当不在现实世界的时候，他就不能打代码...

影片开头的点阵城市动画(惊到我了，以为在学固体物理)，创战纪也重做了一段；另外Kevin的古董车就是1代的摩托。而且时隔近30年，Kevin和Alan竟然还是同一个演员，真的令人满足。

另外第一次听到Crom(控制只读存储器), Ram(随机存储器)这俩名字时笑到了 ps.创战纪的台词致敬： 1. It's all in the wrist!(Kevin秀操作时的台词) 2.Well that is a big door!(破解英康公司的安全门) 3. You will receive an identity disc, everything you do or learn will be imprinted on this disc. If you lose your disc or fail to follow command, you will be subject to immediate de-resolution.(给予光碟时的说明) 4. He fight for the users.(Tron) 5. Greeting programs!

作为开创了CG电影时代的领头军，如果剧情和人物质量可以跟得上特效和技术的话，那么这部电影一定会成为不朽的经典：反乌托邦式的故事背景、人类进入电子与电脑争夺主权、人类与程序合作、程序有自己的意识和情感。然而精彩的视效和三维动画的映衬下包裹的只是一个流于表面的故事，无法深刻触及电脑技术飞速发展下的危机意识。但看完了这部电影，一种感觉久久不散，那就是：刚才看到的东西好流弊啊！

本片服装获得奥斯卡最佳服装设计奖提名，由光线构成的极具现代感的线条让这些演员的一举一动极富舞感。为此它只获得了奥斯卡最佳服装设计提名而感到不服，去查阅后发现当年的各项奖项领跑者是《甘地传》，只好做小伏低状。大神在此，只叹生不逢时。

利用光源区别身份以及状态的设定不仅直观且有美感，现在看来当时的特效深深带有怀念美。男主角带着“最年轻的天才程序员”光环在VR游戏里几乎畅通无阻，感觉所有热爱电脑或挣扎在编程中的人都可以来此一战。路逢光源站喝水很担心他们会在补充能量的过程中被对方晃瞎，好在大家都是同一个梦想下的程序，不需要互相伤害。

两男一女的设定真的很诡异，女人看起来和男2是CP偏偏坦白喜欢男1，而电脑中的程序女在以为男2死了后不出几分钟便和男1眉目传情并在大BOSS主程序下深吻，发现男2没死后又跳着雀跃的小步伐奔向了男2，真是爱像一阵风，吹完他就走~~~

影片中的程序世界一旦以人类的姿态活跃于荧幕之上但觉得可怜，或许是因为奴役有思想的生物让人觉得罪恶，也或许是因为气势凌人的凌驾在另一种生物上会让人怀疑这孩子从小缺爱。前几天一只俄罗斯的越狱机器人仅仅跑了五十米就被抓了回来，不难想象它之后被分解的过程。不过科技就是要给人带来便捷而非制造更多的不安，如果人类的发展还未脱离神之掌控的话，那么机器的发展想必也可以在人类翻云覆雨手里。

电脑里的程序们被困在种种框架中，他们的使命就是完成上面派下来的所有人物，而现实中程序员们活动的世界也被钢筋水泥划分出了区域，本质上带着绝望的相似感。如果程序是电脑高手手中的玩物，那么人类又会是谁手里的积木呢。那些相似度过高的格子间暗喻了上班族的牢笼，迷宫般的游戏世界代表着成人世界的险恶规则。感觉编剧在这个故事上还没有彻底放开手脚，自由意志虽然战胜了主程序却选择服务于人类，这是否讽刺着人类永远不能摆脱来自自身抑或类神的制约呢。

For my own records.

1. Math, Calculus and counting

I never quite understood calculus until I heard someone put it this way, not the original words but the basic ideas: before calculus, we are doing measuring shapes of very conventional shapes, like squares, rectangles, triangles, we got all the simple formulas, mutilple by each sides etc. then how about irregular shapes, how do we calculate the areas? yes we do it by couting tiny unit squares inside whatever shapes, then sum the whole thing we got the area! does it sound familiar, yes its almost the idea of Riemann sum, which is the very foundation of calculus. of course things get messier and messier after introducing more shapes functions and extended everything into higher dimensions, like not only do we want to calculate area which is summation of 2D space, we also want to know the volume aka 3D space summation.

So, all i want to say is, calculus is mathmatical counting at a more general/complicated level, with calulus we count every fucking thing. This is in fact in line with the basic idea of math(or my personal very shallow idea of what math actually is), math is counting, of couse people will argue its more than that! but I insist, the very core idea of math is counting, and only after that do we have all the general summaries of truth or patterns discovered by counting numbers. then why do we count? because we need to measure. how do we measure? we measure by addition. we mearue length by counting all the unit dots in a line; we measure areas by adding unit lines together, imagine adding all unit dots in one line, then do it repeatly, which is how multiplying works; we measure volumes by adding areas together, which feels like an iteration of areas addition on top of an iteration of lines addition on top of an iteration of unit dots addition. how about 4th dimention then? another iteration on top of 3d measures.

Back to the idea, why do I talk about elementary computations that every kid knows? Because I want to conclude(feel free to disagree) that math is about counting, and finding patterns through counting. We use counting to measure/symbolize/understand world. I guess thats why peopel always say math is the closest to truth/nature/god etc.

2.logic and programming

Lets start with a basic question. What is computer? Its a machine which do computing just like its name! how does it do it? it does computations by fliping bits which is the basic unit of chips, by fliping massive amount of tiny bits in very short period of time, computers counting/computing/recording numbers. So again, what exactly does computer do? put it in a more abstract way, it does simulations of complicated computing procejures.

One word, simulations, it is what I want to describe the essence of computers in relation with the major topics I want to talk about here.These multi-stage simulations are carried out by a combination of computing numbers and logics simulations. Here I first mentioned logic. In mathmatics, logic has more rigorious definition, but I want to think it in a simple way, it is the glue to gluing numbers counting and stages of counting together.

So what is programming according to all my previous definitions of logic and computers? I think, programming is to create simulations of combinations of different countings and logics, though this whole process takes so many stages from a bit flip on the chips to high level programming abstractions like declare a variable.

3.to put it simple

To summarize, math is counting, programming is to create simulations of countings glued by logics. computer gives us tremendous amount of power to do all kinds of simulations, and by doing all these simulations we can find answers to specific questions, we can optimize answers, we can basically simulate/abstract/recreate the real world since we already tried to simulate everything.

4.why are we talking about all these abstract concepts?

The point is simulation.

We want to simulate everything in real world. and math, logic and programming are the tools we use to build all kinds of simulations. Essentially, we are recreating the real world in a digital/mathmatical/logical(simplified) way. When people are talking about AI, machine learning, all kinds of algorithms, and sounds crazy concepts like AI taking over the world, mind uploading, maybe all these could be viewed in a different way: they all are simulations of the real world. Then they are not so mind blowing after all, they are in fact the very logical progression of human civilazition, we are in fact heading towards another new world which is created by ourselves based on abstractions of the pyhsical world.

5.how does it relate to the movie?

The movie introduced very advanced concepts like AI master control program, human digitalized into computer simulated world, they look fictional, they sound unreal. However, they are in line with the directions we are heading to. And it is in some sense definitive. I personally believe they are achievable, people say si-fi predicts the future, I think si-fi draws blueprints for the future and we humans create the future based on it. Anyway, I think this movie was so advanced and still relating till this day, we are heading towards all the ideas this movie presented.
