Joe,
Even though the apparent speed of reaction may be very fast (time between switch-on and effect), the actual electrons only move at a rate of a few millimetres per second (or a fraction of an inch per second for the old fashioned units).
Also, it was only the fact that the discoverers of how electricity worked decided, at that time, that the flow was from 'positve' to 'negative', (and got it wrong) that actual electron flow is opposite to our current flow convention. It was too much upheaval to change everything around, by the time it was fully understood!
Regards, RAB
