I don't think it's fair to compare what might happen in the future. In my mind the metaphor is more like "instead of having paparazzi at your door following around, you show everyone a card saying that you like dogs and video games and the steelers, and you tend to shop at big box stores out of town". I'd rather know exactly what I'm presenting, which is possible in this model, than have the paparazzi all over me figuring most of it out imperfectly anyway.
