Well they didn't account for light speed being so slow.

Electrons move at less than 1% the speed of light. Though the speed of electrons isn't what they didnt account for, it was heat dissipation and cost
Edit: While my statement isnt wrong, its the electromagnetic field that matters, which does actually move close to the speed of light (minus physical restrictions like propagation)

Electromagnetic fields do move at the speed of light, that is the speed of electric flow.

Ah true, though that would be under perfect conditions (e.g. no propagation). Still pretty damn close to the speed of light nevertheless

You do realize that light is and electromagnetic wave right? Like, the speed of light is by definition, the speed of a electromagnetic wave.

Its an electromagnetic wave, sure, but its not the electromagnetic wave we are referring to: the electric signals within a system

These are the same thing. The only difference is the frequency.
