"Personalization has a price. Throughout the PlayStation Meeting 2013, Sony's representatives keyed in on "personalization" as one of the main facets behind the development of the PlayStation 4. It seems like a benign, a thoroughly positive concept—that a company considers the preferences of its users and then tailors the user interface in the form of relevant searches and recommendations. The system learns your behavior, your likes and dislikes, and offers advertisements and products that fall within your general comfort zone."
