Google has the largest search engine in the world, biggest video platform (YouTube), biggest web browser (Chrome), most-used email service (Gmail,) and the largest mobile operating system (Android).

What that all means is that Google essentially knows everything about us — be that what we search for, what ads we click on, what we write about, what we watch, and what apps we like.

Google's moonshot projects — like Google Glass and driverless cars — are merely the next steps in Google's quest to become a total knowledge company. Google's driverless cars mean the company will know your driving habits and where you like to go. With Glass, people can access information in real-time without having to check a phone.
