I always explain it to people like waves in the sea. The bobbing up and down isn’t the water molecules travelling they are simply going up and down as the wave moves through the water. People seem to accept this analogy as, even if the water thing is new information to them, it’s easier to visualise. |

It's not about the misconception about "AC is vibrating so how can electrons be delivering their energy from the power plant to the light bulb far away?"
They are talking about how the electric field is outside the wires almost entirely.
Their argument is that in the water wave analogy, the wave wouldn't be in the water at all, because it's "actually" transmitted via an invisible field in the space above the water, which pushes back on the water farther away.
Most respected electricity/physics YouTubers disagree with Veritasium's emphasis on this perspective, by the way. The think he conflated the first misconception I mentioned with the second idea, which is about how you model electric circuits.
