自然语言处理。我第一次遇到这种情况是在20世纪90年代初，当时使用的是赛门铁克(Symantec)的一个名为Q&A的程序，它允许您通过键入英文查询来查询数据库。直到今天，我仍然对它印象深刻。

回答“为什么新思想会消亡”和“如何应对”这两个问题?

I suspect a lot of the lack of progress is due to the massive influx of capital and entrenched wealth in the industry. Sounds counterintuitive, but I think it's become conventional wisdom that any new idea gets one shot; if it doesn't make it at the first try, it can't come back. It gets bought by someone with entrenched interests, or just FAILs, and the energy is gone. A couple examples are tablet computers, and integrated office software. The Newton and several others had real potential, but ended up (through competitive attrition and bad judgment) squandering their birthrights, killing whole categories. (I was especially fond of Ashton Tate's Framework; but I'm still stuck with Word and Excel).

怎么办呢?首先想到的是Wm。莎士比亚的建议:“让我们杀了所有的律师。”但恐怕他们现在装备太精良了。实际上，我认为最好的选择是找到某种开源计划。它们似乎比其他选择更好地保持可访问性和增量改进。但是这个行业已经变得足够大了，所以某种有机的合作机制是必要的。

I also think that there's a dynamic that says that the entrenched interests (especially platforms) require a substantial amount of change - churn - to justify continuing revenue streams; and this absorbs a lot of creative energy that could have been spent in better ways. Look how much time we spend treading water with the newest iteration from Microsoft or Sun or Linux or Firefox, making changes to systems that for the most part work fine already. It's not because they are evil, it's just built into the industry. There's no such thing as Stable Equilibrium; all the feedback mechanisms are positive, favoring change over stability. (Did you ever see a feature withdrawn, or a change retracted?)

关于SO的另一个讨论线索是臭鼬工厂综合症(参考:Geoffrey Moore):在大型组织中，真正的创新几乎总是(90%以上)出现在自发出现的未经授权的项目中，这些项目完全由个人或小团队的主动性推动(通常会受到正式的管理等级的反对)。所以:质疑权威，反抗体制。

也许是从客户端服务器到点对点的转变。我讨厌整个云/SAS的原因之一是，它是一种客户端/服务器的回归。

我口袋里有VAX你却让我假装是VT-100?

几乎是现代3D计算机图形学中所有重要的东西。射线追踪(在计算图形意义上)是从Whitted 1980年的论文开始的。行军立方体('87)是从3D数据中提取等值面的标准方法。

增强现实

真实世界的视图与虚拟元素以某种方式结合在一起。

“虚拟现实”一词出现于1989年，比“增强现实”一词出现早了几年。

一些早期的使能技术是在1980年之前发明的，但这个概念本身可以追溯到90年代初(至少维基百科是这么说的)。

也许科幻作家论坛能给你更有趣的答案?: -)

我怀疑这里有一点谬误，你把技术和科学的历史看作是一个稳步前进的过程，是一个线性现象。我怀疑这实际上是一个时断时续、背景、经济、意外发现和普通随机性的过程。

你应该感到幸运，因为你处于历史浪潮的中心，大多数人都不会有这样的经历。
