I remember when i would watch the Jetsons and all the Back to the Future movies and picture what the future would be like. I loved thinking about all the robots doing everything for me, the whole meal in a beep, etc. But what I have realized is that we ARE the future, we are living it day a day.
It was only until 1971 under the Nixon Shock that the US Government stopped backing up fiat currency with gold. Can you imagine? and now all we need is a chip that will store all of our shopping history and information. What coupons we ave, what balance we have on gift cards, what stores we shop the most at, etc. Starbucks had the idea and Google made it big. I think it will be only a couple of years until having cash will be a rarity... something that our grand kids will be like.... "Really grandma, you still have to count those quarters?"
Now the only thing we are missing is the personal greeting at the door with comments about our last visit at the store, want to take a guess what movie had that? Minority Report. It had the whole face recognition theme, back in 2002 and what are arguing about in Facebook and last weeks' post? how face recognition was becoming a reality and how it would impact our privacy rights. The truth is; we dream of these things and think they are super cool, but, once we have them or we realize they are here to become part of our day to day lifestyle we don't embrace them.
Facebook has become the next best thing to learn what interest humans and why not recognize it... We let it happen, it is our option to have a profile, to check the updates, to comment on every single picture someone else uploads, and we choose to "like" something.
Companies have captured and taken advantage of this free customer service outlet, up to the point that "Facebook has become an effective tool for overseeing all departments of ... companies"
