有目的的游戏——像Luis von Ahn和他的团队正在开发的集体智慧工具在1980年之前可能是一个梦想，但当时没有一个广泛部署的网络，可以容纳数百万人，并且需要(例如reCAPTCHA)来实现它。

我认为计算中的大多数概念都在不断改进，但也有一些新的发展，特别是在分布式计算方面。

对故障和缺陷的鲁棒性，以及故障恢复，即。Paxos，拜占庭容错等。 我知道人们提到过P2P, P2P通信发生在70年代，但恕我直言，我不认为它具有与今天相同的性质，具有分布式哈希表，高效的动态自组织网络，最重要的是，匿名性(例如Freenet, Tor)。

大多数工作都经过了改进，虽然许多现代系统比60年代或更早时候首次描述的原始概念好不了多少，但有些系统好了几个数量级。

至于编程概念，IoC /依赖注入在1988年，根在1983年。福勒在他的Bliki上对这个概念的历史做了一些注释。

飞行汽车和悬浮滑板。哦，等等，那些还没有被发明出来。但到2015年，我们必须拥有它们。否则《回到未来2》就是个弥天大谎!

我认为没有什么重要的东西被发明出来。但自80年代以来，人们对软件的看法发生了很大变化。那时有更多的理论家参与其中，现在你在一个程序员论坛上问这个问题。

当时的大多数想法都没有得到实施，或者即使实施了，它们也没有任何真正的重要性，因为当时的软件行业还不存在，市场营销、人力资源、开发阶段或alpha版本也不存在:)。

Another reason for this lack of inventions is the fact that most people use Windows:) dont get me wrong, i do hate M$, but look at it this way: you have a perfectly working interface, with nothing new to add to it, maybe just some new colored buttons. Its also closed enough so you wont be able to to anything with it without breaking it. Thats why i prefer open apps, this way you get more "open" people, to whom yo can actually talk, ask then questions, propose new ideeas that actually gets implemented, or at least put on an open todo-list, thus you get some kind of "evolution". You dont really see anything new because you are stuck with the same basic interface "invented" lots of years ago... did anyone actually tried ION window-manager in a production environment? It has a new kind of interface, and actually lets you do things faster, event it it looks quirky

M$, Adobe..you name it,holds lots of patents so you wont be able to base your work on them, or derivatives(you also wont know what kind of undeveloped tehnologies they hold). Look at MP3 and GIF as examples( i belive that they are both free formats now, but they are also kinda dead..) MP3 is the 'king' of audio evend if there are few algorithms out there much better that it..but didnt get enough traction because they weren't pushed on the consumer market. The GIF... come on, 256 colors??? From this point of voew i'm curios how many people from this thread are working on something "open" that will get to be reused in some other projects, and how many on "closed", protected by NDA's projects?

即使这听起来有点像“免费的威利”，但在80年代，软件是免费的，所有东西都有文档，所有硬件都更简单，更容易使用……同时也更加有限，所以人们并没有浪费时间去执行3d游戏或网页，而是致力于真正的算法。

上世纪八十年代初，施乐帕洛阿尔托研究中心对计算机蠕虫进行了研究。

摘自John Shoch和Jon Hupp的“蠕虫”程序——分布式计算的早期经验”(ACM通讯，1982年3月，第25卷第3期，172-180页，1982年3月):

In The Shockwave Rider, J. Brunner developed the notion of an omnipotent "tapeworm" program running loose through a network of computers - an idea which may seem rather disturbing, but which is also quite beyond our current capabilities. The basic model, however, remains a very provocative one: a program or a computation that can move from machine to machine, harnessing resources as needed, and replicating itself when necessary. In a similar vein, we once described a computational model based upon the classic science-fiction film, The Blob: a program that started out running in one machine, but as its appetite for computing cycles grew, it could reach out, find unused machines, and grow to encompass those resources. In the middle of the night, such a program could mobilize hundreds of machines in one building; in the morning, as users reclaimed their machines, the "blob" would have to retreat in an orderly manner, gathering up the intermediate results of its computation. Holed up in one or two machines during the day, the program could emerge again later as resources became available, again expanding the computation. (This affinity for nighttime exploration led one researcher to describe these as "vampire programs.")
