飞行汽车和悬浮滑板。哦，等等，那些还没有被发明出来。但到2015年，我们必须拥有它们。否则《回到未来2》就是个弥天大谎!

忆阻器。

虽然这个想法并不比1980年更新，但我相信直到2008年才有了一个可行的模型。如果它能通过研发，它将是自晶体管以来计算机硬件领域最重大的进步;至少，消除了次要记忆。

更好的用户界面。

今天的用户界面仍然很糟糕。我指的不是小的方面，而是大的、基本的方面。我不禁注意到，即使是最好的程序也仍然有一些接口，这些接口要么极其复杂，要么需要以其他方式进行大量的抽象思考，而且无法达到传统的非软件工具的易用性。

诚然，这是由于软件可以比传统工具做更多的事情。但这不是接受现状的理由。此外，大多数软件都做得不好。

In general, applications still lack a certain “just works” feeling are too much oriented by what can be done, rather than what should be done. One point that has been raised time and again, and that is still not solved, is the point of saving. Applications crash, destroying hours of work. I have the habit of pressing Ctrl+S every few seconds (of course, this no longer works in web applications). Why do I have to do this? It's mind-numbingly stupid. This is clearly a task for automation. Of course, the application also has to save a diff for every modification I make (basically an infinite undo list) in case I make an error.

解决这个问题其实并不难。在每个应用程序中都很难实现它，因为没有好的API可以做到这一点。编程工具和库必须显著改进，才能在所有平台和程序上轻松实现这些工作，适用于所有具有任意备份存储且不需要用户交互的文件格式。但在我们最终开始编写“好的”应用程序而不仅仅是足够的应用程序之前，这是必要的一步。

I believe that Apple currently approximates the “just works” feeling best in some regards. Take for example their newest version of iPhoto which features a face recognition that automatically groups photos by people appearing in them. That is a classical task that the user does not want to do manually and doesn't understand why the computer doesn't do it automatically. And even iPhoto is still a very long way from a good UI, since said feature still requires ultimate confirmation by the user (for each photo!), since the face recognition engine isn't perfect.

标签，信息分类的方式。是的，就是每个问题下面的小方框。

令人惊讶的是，标签发明花了大约30年的时间。我们使用了目录和目录;我们使用了为印刷书籍优化的东西。

然而，30年比人们意识到印刷书籍可以用更小的格式的时间短得多。人们可以把书放在手里。

我认为核心CS玩家低估了标签概念。所有的研究都集中在自然语言处理(自顶向下的方法)。但是标签是第一种计算机和人类都能很好理解的语言。这是一种自底向上的方法，使计算机使用自然语言。

它提供了一种信息丰富的方式来传播信息和辩论。我发现它比标准的采访更具互动性，但没有博客评论那么嘈杂。

我认为没有什么重要的东西被发明出来。但自80年代以来，人们对软件的看法发生了很大变化。那时有更多的理论家参与其中，现在你在一个程序员论坛上问这个问题。

当时的大多数想法都没有得到实施，或者即使实施了，它们也没有任何真正的重要性，因为当时的软件行业还不存在，市场营销、人力资源、开发阶段或alpha版本也不存在:)。

Another reason for this lack of inventions is the fact that most people use Windows:) dont get me wrong, i do hate M$, but look at it this way: you have a perfectly working interface, with nothing new to add to it, maybe just some new colored buttons. Its also closed enough so you wont be able to to anything with it without breaking it. Thats why i prefer open apps, this way you get more "open" people, to whom yo can actually talk, ask then questions, propose new ideeas that actually gets implemented, or at least put on an open todo-list, thus you get some kind of "evolution". You dont really see anything new because you are stuck with the same basic interface "invented" lots of years ago... did anyone actually tried ION window-manager in a production environment? It has a new kind of interface, and actually lets you do things faster, event it it looks quirky

M$, Adobe..you name it,holds lots of patents so you wont be able to base your work on them, or derivatives(you also wont know what kind of undeveloped tehnologies they hold). Look at MP3 and GIF as examples( i belive that they are both free formats now, but they are also kinda dead..) MP3 is the 'king' of audio evend if there are few algorithms out there much better that it..but didnt get enough traction because they weren't pushed on the consumer market. The GIF... come on, 256 colors??? From this point of voew i'm curios how many people from this thread are working on something "open" that will get to be reused in some other projects, and how many on "closed", protected by NDA's projects?

即使这听起来有点像“免费的威利”，但在80年代，软件是免费的，所有东西都有文档，所有硬件都更简单，更容易使用……同时也更加有限，所以人们并没有浪费时间去执行3d游戏或网页，而是致力于真正的算法。
