Technology has played a huge role in globalization and the spreading of culture and we can see it in every culture aspect, be it music, food, art, etc. We can see the globalization of culture when sushi, shawarma and hum-pao are common things we can find in any food court, where we can enjoy the latest italian cinema festival. Now more than ever we have the world in the palm of our hands, smartphones have the capacity to tnsport you to virtually any place on earth with the touch of a button. Regarding the preervation of cultural identity it can be tricky, on one hand, we have certain countries and popuations fighting to keep up what makes them unique, and on the other hand, the newer generations tend to get confused a to what is their proper cultural identity because they have been bombarded with information from all over the world since they were born.
Hope this helps!
