I can't remember a time in my life when I wasn't involved in sewing or some sort. My mother was a beautiful seamstress although she never quilted. My daughter has no desire to sew anything. My daughter-in-law on the other hand enjoys sewing but has never had anyone to really teach her until she became a part of our family because she was never around anyone who sewed. It is fun doing things with her.
I spent years in the college environment as a professor. What I noticed about younger people in recent years is how impatient they are and their perception of being busier than anyone else. Products have been developed (cell phones, texting, computers, instant food, etc) to address this. I think this will also impact all sorts of arts, sewing and quilting included. We can see that in patterns today - quick and easy; equipment - die cutters, machines that go faster, thread themselves, cut the thread etc. I don't think quilting will die but the way we quilt will likely change.
