EE details relevant to electronics board designers are kinda important and interesting, and I have a lot of sympathy for "technically correct". But that veritasium video was a trick question, and a misleading video. It subtly shifted between ideal model to real-world effects to smugly show how most skilled EEs are wrong about electricity, but Derek knows the truth.
In a simplified circuit model it would work like a circuit, in a as-real-world-as-possible model it would always be dominated by interference. In a carefully-segregated-semi-real model, it would be less than 1% on after 1/c seconds, would you really call that on? If it was, then 100% on would be way too much current!
So many minutes spent without explaining that the real world is very complicated and EEs apply different models to different situations as appropriate, and it's silly to say that only the field matters not the electrons because of course the electrons cause the field while the field moves the electrons, and the original question is a trick because it's an idealized thought experiment which tries to trick you into applying the wrong model but that's silly because it's an idealized thought experiment which wouldn't work in the real world so it's only purpose is to exercise a simplified model ...
Great fodder for a series of viral-y videos from multiple youtubers though. (electroboom's response was pretty good IMHO)
