即时消息已经出现很长时间了(60年中后期)，但是IRC在1988年之前还没有出现。

除此之外，视频通讯(比如，Windows Live Messenger，或Skype，或……)确实改变了我们的沟通方式;)而且是最近才出现的。

<修改> (见VideoConferencing: 1968, alt text http://wpcontent.answers.com/wikipedia/en/thumb/6/64/On_Line_System_Videoconferencing_FJCC_1968.jpg/180px-On_Line_System_Videoconferencing_FJCC_1968.jpg，正如Alan Kay自己在评论中指出的那样:

请再次查看恩格尔巴特在1968年演示的内容(包括实时视频聊天和屏幕共享)。低，猜测真的没有查东西管用。这就是为什么大多数人对事物的发明时间做不充分的假设。)

把它放在我的脸上;)，这是理所当然的。

注意:那个时代的“网络摄像头”(视频设置)并不是为普通的客厅设计的;)

网络摄像头替代文本http://wpcontent.answers.com/wikipedia/commons/thumb/c/c5/Logitech_Quickcam_Pro_4000.jpg/180px-Logitech_Quickcam_Pro_4000.jpg的推广也有帮助(始于1991年，第一个这样的摄像头，称为CoffeeCam，是针对剑桥大学计算机科学系的特洛伊房间咖啡壶)。

所以:80后:2 / 3:IRC和网络摄像头。

第一台真正的多媒体个人电脑，Amiga:第一台32位抢先处理多任务的个人电脑，第一台硬件图形加速，第一台多声道声音，在许多方面，它比现在流行的多核、多兆赫的Windows盒子机更有用、更强大。

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.

如果我们作为一个团体认真地回答这个问题。 不幸的是，我相信我们需要的不仅仅是一串随机的善意的帖子! 我知道，这听起来很无聊，但经常把事情做完才是!

We Write a list of powerful ideas in the area of computing Maybe we should define a few categories to separate each one because videoconference somehow does not fit well with object oriented programming. Seeing ideas by categories makes it easier to generate them without redundancy. It's too easy to sidetrack in teleportation if quantum computing is not kept away from flying cars. Try to attribute each of them a date This will settle the before/after 1980 and restrict debate about each idea to its own. It will be fun to dig for earliest reference, first known implementation, etc. Plus this will allow people like me who were 2 years old in 1980 to have a better idea of what was common programming knowledge in 1980 (nothing beats being there at the time) Try to attribute each of them the current state of their implementation Ok, some idea were sci-fi in 1850, with early development in the 1970 and serious improvement breakthrough in the 1990. Some ideas are just starting to get around. Some are almost forgotten. Probably the wiki thing is a good idea. I think this could really get somewhere if slightly organized. I did not check, but maybe this whole thing already exist already on the net (I usually find that if you think about something, someone already did it). What do you think ? Cheers !

我不知道是否有人已经回答了，“机器学习”作为一个重要的新发展，正在迅速发展。智能垃圾邮件过滤、股市预测、机器人等智能机器……

也许，机器智能会是下一个大事件。
