Summarize the following quote: "A vast work of formation is needed to assure that the mass media be known and used intelligently and appropriately. The new vocabulary they introduce into society modifies both learning processes and the quality of human relations, so that, without proper formation, these media run the risk of manipulating and heavily conditioning, rather than serving people. This is especially true for young people, who show a natural propensity towards technological innovations, and as such are in even greater need of education in the responsible and critical use of the media." -- Saint John Paul the Great, Apostolic Letter The Rapid Development (2005), no. 11
