You would have thought, "Wow! I can now call my Aunt Glenda from the car and wish her a happy birthday.
你一定會想：“哇喔！我現在可以在車里打電話給我姨媽Glenda，祝她生日快樂了。
I can call anyone, anytime. This is the future!"
我現在能給任何人在任何時間打電話了。這就是未來！”
Little did you know, you would tap on that phone to make dinner reservations for you and Aunt Glenda to celebrate together.
你還并不知道，你會撥通電話來預訂晚餐，讓你和Glenda姨媽一起慶祝。
With another tap, you'd be ordering her gift.
撥打另一通電話，你將訂好她的禮物。
And yet one more tap, and you'd be "liking" Auntie Glenda on Facebook.
而且每多一次撥號，你將會被Glenda姨媽在Facebook上“點贊”。
And all of this, while sitting on the toilet.
而你可以坐在馬桶上做完這所有的事。
It is notoriously hard to predict where new technology might take us.
新技術將把我們帶往何處，誰都說不準。
And the same is true for personal DNA technology today.
對如今的個人DNA技術來說，情況也是一樣。
For example, I could never have imagined that a truffle farmer, of all people, would use personal DNA machines.
舉個例子，我從來沒想過一個種松露的農民，怎么會需要用到個人DNA檢測設備。
Dr. Paul Thomas grows truffles for a living.
Paul Thomas博士以種植松露為生。
We see him pictured here, holding the first UK-cultivated truffle in his hands, on one of his farms.
我們可以看到，在這張照片里，他在他的一個農場里，手里拿著第一個尿激酶培養的松露。
Truffles are this delicacy that stems from a fungus growing on the roots of living trees.
松露如此美味，源于一種在活的樹根生長的真菌。
And it's a rare fungus. Some species may fetch 3,000, 7,000, or more dollars per kilogram.
這是一種罕見的真菌。一些種類每公斤能賣到3000、7000美元，甚至更多。
I learned from Paul that the stakes for a truffle farmer can be really high.
我從保羅那了解到種松露的農民的收益可以很高。
When he sources new truffles to grow on his farms, he's exposed to the threat of knockoffs
當保羅獲得生長在他的農場的新松露時，他被置于仿冒品的威脅之中
truffles that look and feel like the real thing, but they're of lower quality.
這種松露的外觀和感覺很像真的，但是它們的質量很差。
But even to a trained eye like Paul's, even when looked at under a microscope, these truffles can pass for authentic.
不過即使有一雙像保羅那樣訓練有素的眼睛，在顯微鏡下觀察，這些松露都可以通過真品的檢測。
So in order to grow the highest quality truffles, the ones that chefs all over the world will fight over, Paul has to use DNA analysis.
為了種植最高質量的松露，那些世界各地的大廚所競相爭奪的松露，保羅必須使用DNA分析。
Isn't that mind-blowing?
這難道不令人大開眼界嗎?
I bet you will never look at that black truffle risotto again without thinking of its genes.
我敢打賭你以后看著黑松露意大利調味飯，都不得不想到它的基因。
