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.

一些回答提到了量子计算机，好像它们还在遥远的未来，但我不敢苟同。

There were vague mentions of possibility of quantum computers in 1970s and 1980s (see timeline on Wikipedia), however the first "working" 3-qubit NMR quantum computer was built in 1998. The field is still in infancy, and almost all progress is still theoretical and confined to academia, but in 2007 company called D-Wave Systems presented a prototype of a working 16-qubit, and later during the year 28-qubit adiabatic quantum computer. Their effort is notable since they claim that their technology is commercially viable and scalable. As of 2010, they have 7 rigs, current generation of their chips has 128 qubits. They seem to have partnered with Google to find interesting problems to test their hardware on.

我推荐这段简短的24分钟视频和维基百科上关于D-Wave的文章作为快速概述，在这个由D-Wave创始人和首席财务官撰写的博客上有更多的资源。

包管理和分布式修订控制。

这些软件开发和分发方式的模式是最近才出现的，并且刚刚开始产生影响。

Ian Murdock称包管理是“Linux给业界带来的最大进步”。他会的，但他说得有道理。自1980年以来，安装软件的方式已经发生了重大变化，但大多数计算机用户仍然没有经历过这种变化。

Joel和Jeff在播客#36中与Eric Sink讨论了版本控制(或版本控制，或源代码控制)。似乎大多数开发人员还没有跟上集中式系统的步伐，DVCS被广泛认为是神秘和不必要的。

来自播客36的文字记录:

0:06:37 阿特伍德:…如果你假设——这是一个很大的假设——大多数开发人员都掌握了基本的源代码控制——坦白地说，我发现这是不正确的…… Spolsky:没有。他们中的大多数人，即使他们知道，也只是签入和签出，但分支和合并——这让他们感到困惑。

1980年1月2日我开始编程。我试着思考在我的职业生涯中有哪些重大的新发明。我很难想出一个。大多数我认为重要的东西实际上是在1980年之前发明的，但直到1980年之后才被广泛采用或改进。

Graphical User Interface. Fast processing. Large memory (I paid $200.00 for 16k in 1980). Small sizes - cell phones, pocket pc's, iPhones, Netbooks. Large storage capacities. (I've gone from carrying a large 90k floppy to an 8 gig usb thumb drive. Multiple processors. (Almost all my computers have more than one now, software struggles to keep them busy). Standard interfaces (like USB) to easily attach hardware peripherals. Multiple Touch displays. Network connectivity - leading to the mid 90's internet explosion. IDE's with Intellisense and incremental compiling.

虽然硬件有了巨大的进步，但软件行业一直在努力跟上。我们比1980年领先了几光年，但大多数改进都是改进，而不是发明。自1980年以来，我们一直忙于应用技术进步，而不是发明创造。就其本身而言，这些渐进式的发明大多不重要或不强大，但当你回顾过去29年，它们相当强大。

我们可能需要接受渐进式的改进并引导它们。我相信真正原创的想法可能会来自很少接触计算机的人，而且他们越来越难找到。

我认为，在1980年，如果你在使用一台电脑，你要么是在赚钱，要么就是一个极客……那么发生了什么变化呢?

Printers and consumer-level desktop publishing. Meant you didn't need a printing press to make high-volume, high-quality printed material. That was big - of course, nowadays we completely take it for granted, and mostly we don't even bother with the printing part because everyone's online anyway. Colour. Seriously. Colour screens made a huge difference to non-geeks' perception of games & applications. Suddenly games seemed less like hard work and more like watching TV, which opened the doors for Sega, Nintendo, Atari et al to bring consumer gaming into the home. Media compression (MP3s and video files). And a whole bunch of things - like TiVO and iPods - that we don't really think of as computers any more because they're so ubiquitous and so user-friendly. But they are.

我认为，这里的共同点是曾经不可能的事情(制作打印文档;准确再现彩色图像;实时向世界各地发送消息;分发音频和视频材料)，当时因为设备和物流成本昂贵，现在是消费者水平。那么，大公司现在在做什么过去是不可能的，但如果我们能想出如何做小而便宜的事情，可能会很酷?

任何涉及物理运输的东西都是有趣的。视频会议(目前)还没有取代真实的会议，但如果技术合适，它仍有可能取代真实的会议。一些休闲旅行可以被全感官沉浸式环境所取代——家庭影院就是一个微不足道的例子;另一个是位于Soho区一栋写字楼内的“虚拟高尔夫球场”，在这里，你可以在模拟球场上打18洞真正的高尔夫球。

不过，对我来说，下一个真正重要的事情将是制造。做的事情。勺子，吉他，椅子，衣服，汽车，瓷砖什么的。这些仍然依赖于生产和分销基础设施。我再也不用去商店买电影或专辑了——什么时候我就不用去商店买衣服和厨具了?

Sure, there are interesting developments going on with OLED displays and GPS and mobile broadband and IoC containers and scripting and "the cloud" - but it's all still just new-fangled ways of putting pictures on a screen. I can print my own photos and write my own web pages, but I want to be able to fabricate a linen basket that fits exactly into that nook beside my desk, and a mounting bracket for sticking my guitar FX unit to my desk, and something for clipping my cellphone to my bike handlebars.

与编程无关?不…但在1980年，声音制作也不是。或者视频分发。或者给赞比亚的亲戚发信息。大处着眼，伙计们……：）

数码相机呢?

根据维基百科，第一个真正的数码相机出现在1988年，大众市场的数码相机在20世纪90年代末变得负担得起。
