My vision when we started Google 15 years ago was that eventually you wouldn't have to have a search query at all. You'd just have information come to you as you needed it. And Google Glass is now, 15 years later, sort of the first form factor that I think can deliver that vision.

Currently we don't have plans on conquering the world.

Some say Google is God. Others say Google is Satan. But if they think Google is too powerful, remember that with search engines unlike other companies, all it takes is a single click to go to another search engine.

In the future, search engines should be as useful as HAL in the movie 2001: A Space Odyssey-but hopefully they won't kill people.
