I think that is possibly the most frightening video I have ever seen.
Google will know where you are, what your doing, what your interested in, who you are with, tell you where to eat, what to eat, when to get on the train, what you'll be doing later and all the while they will be pumping 'choices' and 'content' to you based on who paid them the most money to do so.
Google should not know this much about anyone. Not even your government nay your spouse, should know this much about you, let alone a private company that is open about selling it all to other companies.
I hate google's business model so much that I dedicate a small portion of every day to worrying about it. It makes my tummy hurt. George Orwell couldn't have predicted this kind of intrusion into your mind.
I don't knowingly use any google products at all. I dislike many companies. Google is the only one I hate.
