Would be funny to have a ‘mm Cu / FTE’ scaling law.

The ohm*meter^3 is the unit of electrical resistance.

Is there a name for Wh/m or W/m (of Cu or C) of loss? Just % signal loss?

There's already conductive graphene 3d printing filament (and far less conductive graphene). Looks like 0.8ohm*cm may be the least resistive graphene filament available: https://www.google.com/search?q=graphene+3d+printer+filament...

Are there yet CNT or TWCNT Twisted Carbon Nanotube substitutes for copper wiring?

* far less conductive graphite; another form of carbon

FWIU recent developments in graphene semiconductors for example on silicon carbide are undercapitalized.

Can industry undo its unsustainable copper dependency by replacing power wires and data cabling with TWCNT cabling?

Complexity is a function of the number and depth of suppliers.
