I believe that culture will become a thing of the past for the majority of people as they become incorporated into an increasingly Westernised world. But those 'hang out' with their cultural brethren, they will maintain a visage of their heritage, but they may become confused with how their culture interacts with the western world (i.e. their European friends or their American friends etc) and the role it plays in their lives. They will try to have the best of both worlds by holding on to their favourite parts of their culture alongside western culture.
It will depend heavily on how much they decide to delve into their own heritage and history, because without such knowledge it will be hard for them to feel a connection to their own culture.
Hope that answers some of your question.
