" That’s true,” said Brin. “Ultimately I view Google as a way to augment your brain with the knowledge of the world. Right now you go into your computer and type a phrase, but you can imagine that it could be easier in the future, that you can have just devices you talk into, or you can have computers that pay attention to what’s going on around them and suggest useful information.” “Somebody introduces themselves to you, and your watch goes to your web page,” said Page. “Or if you met this person two years ago, this is what they said to you.” Later in the conversation Page said, “Eventually you’ll have the implant, where if you think about a fact, it will just tell you the answer.” It was a fantastic vision, straight out of science fiction. But Page was making remarkable progress—except for the implant. When asked in early 2010 what will come next for search, he said that Google will know about your preferences and find you things that you don’t know about but want to know about. So even if you don’t know what you’re looking for, Google will tell you. "
