When I did EE 40 years ago we learned both conventional and electron

As for the diode symbol, I just assume an arrow for conventional, or an
old fashioned blunderbuss for electron flow. :-)
In any case how hard is it to understand electron flow is simply the
reverse of conventional flow? And if you know which flows +to- and which
-to+, the rest simply follows. Since neither is an exact representation
of what is really happening, it hardly matters which you choose IMO.

It only matters if you are doing semiconductor physics. Else anything
other that 'conventional' is an irrelevant distraction.

Once you get to the quantum mechanics level, both are irrelevant, but
never considered it a distraction. Simply never bothered me.
