No, he is correct, its the wave that propagates at a fraction of the speed of light (depending on the conductor). The electrons themselves don't move very fast.

"An electron travels at a speed of about 1 cm/sec. " (in copper) per: https://www.informit.com/articles/article.aspx?p=2916283&seq...

This should be taught in a basic AP physics class in HS (where i initially heard it). I vaguely remember doing some of these calculations in my physics for engineers class as a first year engineering student too.

That article is probably wrong too. A changed electric field requires a change in the position of electrons. Hence a fast signal change requires fast position changes.
