Google is selling to the Android crowd, a crowd that will do anything to save a buck, so putting ads on anything and everything certainly makes sense. There are people out there who will buy these products, as long as they cost less than the proper ads free versions of these products.
In the future, Google will be implanting a chip into people for free, and it will be the next version of "Android" in the truest sense of the world. Google will basically own people, and there are definitely people out there who are dumb enough to do this, as long as it's free or extremely low cost. Just look at how many people use cheap and free Android phones. Googles Glass is only a taste of what's to come.
Cross eyed people everywhere will be walking around like robots on drugs, being served up Ads 24-7. Even when they sleep, Google will tap into these people's brains and the word Fandroid will take on a whole new meaning.
It will be the perfect idiocracy society. People wont have to drive themselves anymore, there's Google's automated cars for that, and people wont even have to think anymore, and why should they, because the microchip implanted into their bodies will be much smarter than many people's brains, especially people who can't afford anything.
There is no shortage of cheap people who will whore themselves out to Google, allowing and accepting Ads to placed everywhere.
You're sadly right. If Google had their way, your funeral would be funded by ads, served at the funeral. Ditto your wedding, your baptism, your time on the loo, your honeymoon, etc.
Your child's first word will be "Gurggle."
