In fact, it was so successful that there's no way that these days you could make a book like this.
實際上，互聯網如此成功，以至于如今你不可能出版這樣一本通訊錄了。
My rough calculation is it would be about 25 miles thick.
我粗略計算，如果這本書出版出來將會有25英尺厚。
But, of course, you couldn't do it, because we don't know the names of all the people with Internet or email addresses,
當然，你也做不不出來，因為我們不知道所有上網人的名字，或者電子郵件地址，
and even if we did know their names, I'm pretty sure that they would not want their name, address and telephone number published to everyone.
即使我們知道他們的名字，我確信他們也不愿意將他們的名字，地址和電話號碼公諸于眾。
So the fact is that there's a lot of bad guys on the Internet these days,
事實是當今在互聯網上有很多壞人，
and so we dealt with that by making walled communities, secure subnetworks, VPNs,
我們的應對方法是建立一個封閉的社區、安全子網、虛擬私有網，
little things that aren't really the Internet but are made out of the same building blocks,
以及類似于因特網但又不是因特網的工具，雖然他們擁有相同的構建原理，
but we're still basically building it out of those same building blocks with those same assumptions of trust.
但是我們構建他們并不完全照搬因特網的構建基本原理，而是基于與因特網一樣，對信任的假設。
And that means that it's vulnerable to certain kinds of mistakes that can happen,
這意味著這種網絡易受到某種可能發生的某種錯誤的干擾，
or certain kinds of deliberate attacks, but even the mistakes can be bad.
以及受某種蓄意的攻擊，但是即使是錯誤，也會很麻煩。
So, for instance, in all of Asia recently, it was impossible to get YouTube for a little while because Pakistan made some mistakes in how it was censoring YouTube in its internal network.
例如，最近在亞洲的所有地區，有一小段時間不能訪問YouTube是因為巴基斯坦在其內部網絡審查YouTube的方法上犯了一些錯誤。
They didn't intend to screw up Asia, but they did because of the way that the protocols work.
他們無意于在亞洲墻掉Youtube，但由于的協議工作方式，他們確實短時間內阻斷了Youtube。
Another example that may have affected many of you in this audience is,
另一個可能會影響很多在座聽眾的例子是，
you may remember a couple of years ago, all the planes west of the Mississippi were grounded because a single routing card in Salt Lake City had a bug in it.
你可能還記得在數年前，密西西比州西部的所有飛機停航了，是因為鹽湖城的一個路由卡出現了問題。
Now, you don't really think that our airplane system depends on the Internet, and in some sense it doesn't.
你當然不會認為飛機系統依賴于因特網，在某種意義上它確實不依靠因特網。
I'll come back to that later.
稍后我會再談到這一點。
But the fact is that people couldn't take off because something was going wrong on the Internet, and the router card was down.
事實是人們不能起飛，是因為互聯網出了某種問題，路由卡宕機了。
