Yes but carbon nanotube aren't a material. Until someone figures out how

if/when someone does figure out how to make a useable material out of
nanotubes, it isn't sure that such a material will still be highly
conductive. It might be, in which case yes running electricity in the
cable might make sense.

Gee, weren't you just saying a few hours ago this was totally feasible
with today's technology? Or am I imagining things?

Did you not have carbon nanotubes in mind when you wrote that?
