Paxos协议。很难描述它在互联网时代的价值。

企业服务总线似乎是一个相当新的“发明”，尽管它当然是基于更古老的技术。

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。

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 (Did you ever see a feature withdrawn, or a change retracted?)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

(普遍)加密。没有加密，任何金融交易都不会发生。这仍然是一个需要更多创新和用户友好性的领域。
