You know how when you decide to have a garage tidy the first stage is to chuck everything on the floor.
Next you put all of the rubbish in bags and boxes and put them outside the door to go to the tip.
Next you put all of the stuff that you might sell on ebay or give to a charity shop in a pile.
Then you start organising what is left into boxes and put them onto shelves.
Well Google is at the stage where they have chucked everything on the floor.
That's how you start artificial intelligence.
