As you indicate, there's a ton of it still in the ground and it's not easy in a lot of cases to dig it up or replace, plus it's already invested in, wholesale replacement costs money, and if you don't have to, why bother? In multi-unit housing, it may not be economically feasible or practical to retrofit the building to use anything but the existing wiring. As a result, you see a lot of fiber-to-the-node installations or fiber-to-the-distribution-point, particularly in established rural applications. The death of copper has been preached since I started into this business. Back then copper's savior was HDSL, and ever since there's been some other xDSL technology improvements to squeeze more out of the existing copper plant. So, I'd say realistically you're likely to see copper for a good while longer, but it is getting pushed farther and farther to the edges of the networks. I'm happy for it to stick around for as long as possible. :) Eventually xPON will supplant it, and the Cable company and Telco networks will look virtually identical.
