Way back in the late 1960s-70s when I actually worked for a telco, I told them at every chance that using copper instead of fiber to continue building infrastructure was nuts. They didn't listen. I went on to work for major equipment suppliers in the fiber field, for clients like sprint (pin drop), gte and verizon (fios), at&t, and alcatel. If the telcos had started transitioning to digital and fiber way back around 1970, they'd be in much better shape today. But they are emblematic of the type of thinking of regulated monopolies, where the thin profit margins are used to pay rich bonuses to the upper management. But eventually new technologies are going to eat their lunch, breakfast, and dinner.
