Cable was a system that was installed with what was modern techniques at the time, in order to deliver a fibre optic system directly into homes. Do you remember all the digging that went on along streets in order to lay all the cables.
In contrast BT as it is now, was installed primarily to deliver a phone line into homes, most of the wires at the time were overhead, some still are. That means that all this Internet malarkey was shoe horned into a telecommunication system, so no, wires will never be faster than optic cables. There is no internal resistance on an optical signal, but there is on copper wires, it used to be said the further from the exchange you were the slower the connection. Another reason BT are installing optical cable is that they can multiplex the system, thereby more connections from fewer strands, rather than the dedicated line from home to the person receiving the call.
I have to go for a lie down now my head is throbbing again with all this technical talk.
