Unless it was laid in the 1950s, in which case it's probably aluminium wire rather than copper.

There's an area like that between the local exchange and my house, which meant internet speeds were like living in a time capsule before FTTC came along. Always 25% of what the rest of the town had.

But other than edge cases like mine, I agree. Copper lasts a long time with minimal things to go wrong. Modern solutions like FTTC require their own power, air conditioning, etc.
