这个问题来自于对过去50年左右计算领域各种进展的评论。
其他一些与会者请我把这个问题作为一个问题向整个论坛提出。
这里的基本思想不是抨击事物的现状，而是试图理解提出基本新思想和原则的过程。
我认为我们在大多数计算领域都需要真正的新想法，我想知道最近已经完成的任何重要而有力的想法。如果我们真的找不到他们，那么我们应该问“为什么?”和“我们应该做什么?”

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。
其他回答
什么都没有。
我认为这是因为人们改变了他们的态度。人们过去相信，只要找到“好点子”，就能一夜暴富。如今，人们相信，回报最大的是执行过程，而不是发现过程。你有诸如“想法一毛钱一打”和“第二只老鼠得到奶酪”这样的咒语。因此，人们专注于开发现有的想法，而不是想出新的想法。
万维网已经被告知了，但更基本的，我会说“DNS”。 似乎它是在1983年发明的(http://en.wikipedia.org/wiki/Domain_Name_System)，恕我直言，我们可以认为它是互联网协议的发明和传播到世界各地的能力之间的强制性联系，现在被称为网络。
还是在“网络”部分，我要加上WIFI。它是在90年代发明的(但我同意它不完全是“计算”，而更多地与硬件有关)。
在更严格的“算法”部分，我想到了turbocodes(1993年);有人说它只是接近了香农信号理论所定义的极限，但这种论点难道不会否定所有其他对“一切都已经在洛夫莱斯、巴贝奇和图灵的作品中萌芽”的回答吗?
在密码学领域，我想加上P.Zimmermann(1991年)的PGP程序，它为公民带来了一个相当健壮的(当时)免费加密程序，并有助于动摇政府对加密的立场。事实上，我认为这是密码学“自由化”的因素之一，这是发展电子商务的前提。
这是一个消极的结果，作为一个“基础创新”很奇怪，但我认为适用，因为它开辟了新的研究领域，关闭了无用的领域。
分配共识的不可能性:2001年PODC影响力论文奖
We assumed that the main value of our impossibility result was to close off unproductive lines of research on trying to find fault-tolerant consensus algorithms. But much to our surprise, it opened up entirely new lines of research. There has been analysis of exactly what assumptions about the distributed system model are needed for the impossibility proof. Many related distributed problems to which the proof also applies have been found, together with seemingly similar problems which do have solutions. Eventually a long line of research developed in which primitives were classified based on their ability to implement wait-free fault-tolerant consensus.
开放的PC设计带来了价格实惠的组件(苹果除外)，竞争推动了创新和更低的价格。 这导致了巨大的变化，从用户走向电脑——那里有一个终端可以使用——到电脑来到用户面前，出现在家里，甚至在一个人的大腿上。
如果我们作为一个团体认真地回答这个问题。 不幸的是，我相信我们需要的不仅仅是一串随机的善意的帖子! 我知道，这听起来很无聊，但经常把事情做完才是!
We Write a list of powerful ideas in the area of computing Maybe we should define a few categories to separate each one because videoconference somehow does not fit well with object oriented programming. Seeing ideas by categories makes it easier to generate them without redundancy. It's too easy to sidetrack in teleportation if quantum computing is not kept away from flying cars. Try to attribute each of them a date This will settle the before/after 1980 and restrict debate about each idea to its own. It will be fun to dig for earliest reference, first known implementation, etc. Plus this will allow people like me who were 2 years old in 1980 to have a better idea of what was common programming knowledge in 1980 (nothing beats being there at the time) Try to attribute each of them the current state of their implementation Ok, some idea were sci-fi in 1850, with early development in the 1970 and serious improvement breakthrough in the 1990. Some ideas are just starting to get around. Some are almost forgotten. Probably the wiki thing is a good idea. I think this could really get somewhere if slightly organized. I did not check, but maybe this whole thing already exist already on the net (I usually find that if you think about something, someone already did it). What do you think ? Cheers !
