I have no doubt taht quality will survive. I'm fairly new to the traditional scene and so have had to be selective about what I learn and so will it be for future generations. The advantage they will have is databases such as Mudcat provides that will allow them to listen to something close to the original intent. If it doesn't work for them it won't survive but everything we have today has already withstood the test of time in the most rigorous of environments requiring "hand to mouth" trasnsfer of information. It is not going to fade away overnight.
