忆阻器。

虽然这个想法并不比1980年更新，但我相信直到2008年才有了一个可行的模型。如果它能通过研发，它将是自晶体管以来计算机硬件领域最重大的进步;至少，消除了次要记忆。

个人电脑。

毫无疑问，在过去的30年里，计算最重要的部分是现在每个人都是它的一部分。家用电脑大约从1977年才开始普及，直到80年代才得到广泛应用。现在，幼儿园、老年中心和你的每个邻居都有一台。

Damas-Milner type inference (often called Hindley-Milner type inference) was published in 1983 and has been the basis of every sophisticated static type system since. It was a genuinely new idea in programming languages (admitted based on ideas published in the 1970s, but not made practical until after 1980). In terms of importance I put it up with Self and the techniques used to implement Self; in terms of influence it has no peer. (The rest of the OO world is still doing variations on Smalltalk or Simula.)

类型推断的变化仍在上演;我最喜欢的变体是Wadler和Blott的解决重载的类型类机制，后来发现它为类型级别的编程提供了非常强大的机制。这个故事的结局还在书写中。

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.")

引用艾伦·凯的话:“预测未来最好的方法就是创造未来。”

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……：）
