I think it is closer to the conventional view of current as the travel of electrons down a wire. Current moves far faster than electrons. it is more similar to a wave in the ocean with the electrons being the water molecule. As a result, and counterintuitively for most, the speed of electrons will give you a completely wrong answer for when a light will turn on after you flip a switch. |

Current is the movement of charges. It cannot “move” faster than said charges. (Or, perhaps, you meant the electomotive force that makes the electrons move along the wire, then sure, that thing spreads pretty quickly.)
