This electons flowing rubbish

And don't forget the Fermi energy! That way it's easy to tell conductor, semiconductor and insulator apart.

No, no, no. That’s also wrong.

I would say: charged particles (such as electrons, ions) and quasiparticles (such as electron holes) transported by electromagnetic field.

PS. Should we also declare air flow a BS?

Ah but where are the positrons?

Let's first clear up thoughts of the "Speed of Light". The ONLY thing that travels at the speed of light, is LIGHT.
(And it does that at slightly varying speeds, whether through vacuum/air/diamond etc.! ).  This actually has
nothing to do with the apparent 'speed' of Electricity, which is simply the result of a 'knock-on' effect within
the conductor. In say a 'Super-Conductor' situation, this knock-on effect is just a lot quicker!

This is also wrong.  Speed of light has *everything* to do with the speed of "electricity" (i.e., the speed signal propagation within a circuit). Specifically it is the speed if light in the dielectric surrounding the metal.  In normal situations it doesn't depend on the metal properties at all.  It's the same in superconductors.  This is roughly because it is light: circuit behavior is governed by electric and magnetic fields which propagate at the speed of light.  The reason it depends on the speed of light specifically in the dielectric surrounding the conductors is because electric fields and high frequency magnetic fields are nearly zero inside the conductor.

Electrons do not flow in conductors or semiconductors or anything else when a current is flowing. Yeah Yeah drift current... diffusion current... blah.
Charge is transported around the current path under the influence of the applied voltage.

Of course the OP is right. No 'electons' involved. But ... assuming we are talking of electrons ...

Let's turn the question around - when does an (electrical) current flow without the movement of electrons? Anybody? nobody with their hand in the air?
