People have pointed out that traditional music will continue, because the folk process occurs and music comes from people etc etc etc--but I think that this sort of point misses the real concern--
We live in a world that is changing rapidly, and we are not necessarily adapting to those changes as quickly as they occur--the price of this continuing adaptation to technology seems to be a sacrifice of "the simple pleasures"--social conversation, time with family, and the elements of folk cultural--cooking, music, dancing, crafts, participation sports, etc.
Kids have to make play-dates--What does that do to the transmission of songs, stories and games that is so critical to the transmission of culture?
We exist in a world that is increasingly full of mechanical entertainment, of mechanical music, of mechanical food, a whole mechanical culture, because we don't have the time to participate in it--
How can their be any type of culture, folk or otherwise, when people don't have the time or oportunity to participate in it? And how can we survive for long without that culture?
