Nope, I don't think quilting has become too modernized at all. I think it's all personal preference. I would not have taken up quilting if I had to do everything by hand and use a treadle machine. I absolutely love my computerized embroidery sewing machines and all the tools, patterns and gadgets I have.
I do agree that to make a quilt entirely the old fashioned way would give people appreciation for what they have today.
