In my opinion, relationships in future families will be the same like in our days, because at all times people had the same priorities in relations with members of their families. People will still spend time with their family at home by watching a movie or by cooking food together; by walking anywhere and by doing anything that can strengh their bond. (Ну а вообще, вопрос немного некорректный, потому что это больше касается социологии, нежели английского языка)
