我认为笔记本电脑是在1980年左右发明的，我还认为笔记本电脑和便携式计算机的发展改变了很多人的生活——尤其是那些在IT行业工作的人，或者那些使用电脑和旅行的人。

X.500和X.500系列标准(大约1988年)。虽然x.500标准的灵感来自于几十年前的电信标准，但它们具有重要意义，因为它们为LDAP/AD的广泛使用以及我们目前使用的x.509证书铺平了道路。

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。

我认为这些答案的部分问题是，它们要么没有得到充分的研究，要么是在尝试一种新的实现或一些已经看到重大“改进”的技术。然而，这并不是一项重大发明。例如，任何关于函数式编程或面向对象编程的讨论都是失败的;这些想法在大多数SO参与者出生之前就已经流传了。

I'd say the biggest trend is an ever increasing lack of location dependence and pervasiveness. An interesting philosophical exercise these days is to count the computers in you immediate area. They're everywhere desktops, keyboards, microwaves, radios, televisions, cell phones etc... My grandmother computer is illiterate however her life is as infested with small computers as everyone else's. She can make a call to me from the middle of an empty field. I can then answer that call zipping down the highway.

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 (Did you ever see a feature withdrawn, or a change retracted?)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。
