I learned the correct way in USN ET school in 1959-60 and then when I went to National and elsewhere it was always the lazy thinkers way instead.
I still think the old way as its in my DNA!

Absolutely it is an illusion. IIRC, that was erroneously introduced into
textbooks around 1970 the same time as the "electricity flows from positive
to negative" nonsense. Whoever came up with the latter never heard of
electron flow in a vacuum tube, among other things.

REPLY:

"Hole flow" is an illusion, much like the moving lights on a theater
marquee. If it helps to understand things fine, but holes don't move. It's
more accurate to say a hole is created in one atom and disappears in
another. For a brief time while the electron is in motion, there are
actually two holes.  Neither one "moves".
