That video really annoys me. He's right at one level but totally wrong at another. Yes, you have to explain everything in terms of things people can understand and if they don't know much you can't give a correct explanation... but also, if you actually try, people can understand a lot more than he's pretending they can. Not at a technical level, yeah, but intuitively, it is possible to get general understandings way beyond his attempts at answering that question.

For instance fundamental charges are a lot like positive and negatively-oriented vortices in a fluid, which when they touch cancel each other out and radiate energy away. They're not _exactly_ like that, but they're a lot like it, and that's a model people can understand without knowing the first thing about quantum field theory. Sure, you won't understand from that why like-charges repel each other, not really, but if you play with the analogy for a while it starts to seem why that might be true as well.

(See https://www.ribbonfarm.com/2015/09/24/samuel-becketts-guide-... for some pictures of this... I wish I had better though.)

Magnetism is quite a bit trickier to explain in this model but it can done with some work. In particular: a charge radiates little linear packets of energy just by existing; when one of these packets hits another charged particle it moves a tick closer or further away (based on +/-). A current/moving charge/magnetic dipole radiates away little spiraling packets of energy which are aligned in the plane orthogonal to the conventional magnetic field; when these hit another charged particle they get rotated a tick.
