It's going to see a pattern of what I watch on TV, the websites I visit during the day, and on my phone, who I talk to, where I go, what I do, the kind of business I run, the products I buy, etc, etc.
One night, I'll be watching Breaking Bad and head over to Google on my phone to see what other shows one of the Extras was in.... but Google will already know I'm probably watching Breaking Bad, and Google is going to know that I've looked up Extras before, so guess what, my Google home page is already going to be showing a list of all the Extras that were on Breaking Bad that night before I have to type anything in.
When I turn on my Google Android phone in the morning, the phone will be smart enough to know everything I check every morning. I'll see the weather forecast first, then my sales numbers, probably headlines on Reddit and HN.
When I pull up Google Maps a few days before Fathers day, it's going to know that I'm trying to find my way to various sporting goods stores, it'll automatically put them on the map before I have to type anything in.
If I'm Googling before 5am, guess what, I'm looking up the best fishing reports... it'll be on my Google Home Page.
Or will this all be in front of my face as soon as I put on my Google Glasses?
