The fact that circuit diagrams represent current as flowing in the opposite direction to that in which electrons actually drift makes no difference to making the motors run and the lights go on.

That must be car wiring, we work with AC, and it goes both directions. Most electricians, these days, do get training in DC controls, but don't spend a lot of time with theory, or DC circuitry.

I am a bit different as electricians go, because I started in electronics, and moved to electricity.

I once repaired televisions and the like. i still like to dabble with board level stuff and amplifier design.

Most master electricians don't venture into that field, because there is no need to. There is little money in it anymore.

Not it doesn't: not at the same time. AC goes one direction and then the other, one and then the other. You completely missed his point. Current flows one direction at any time, not both directions simultaneously. His only point is that when designating this in a circuit diagram the convention is to show which way positive current flows, even though what's providing the currents are electrons which are moving in the opposite direction.
