这个问题来自于对过去50年左右计算领域各种进展的评论。

其他一些与会者请我把这个问题作为一个问题向整个论坛提出。

这里的基本思想不是抨击事物的现状,而是试图理解提出基本新思想和原则的过程。

我认为我们在大多数计算领域都需要真正的新想法,我想知道最近已经完成的任何重要而有力的想法。如果我们真的找不到他们,那么我们应该问“为什么?”和“我们应该做什么?”

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。

电可擦可编程存储器,概括为非易失性读/写存储器,目前最著名和最普遍的是Flash。 http://en.wikipedia.org/wiki/EEPROM列出了这个发明于1984年。

通过赋予存储介质与处理单元相同的物理特性、功率要求、大小和稳定性,我们消除了在设计处理器位置时的限制因素。这扩大了我们如何以及在何处为如此多的智能设备(以及以前根本不被认为是智能的东西)赋予“智能”的可能性,以至于我们仍然被这股浪潮所吸引。Mp3播放器只是其中的一小部分。

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.

开放的PC设计带来了价格实惠的组件(苹果除外),竞争推动了创新和更低的价格。 这导致了巨大的变化,从用户走向电脑——那里有一个终端可以使用——到电脑来到用户面前,出现在家里,甚至在一个人的大腿上。
