For some strange reason, Youtube recommended the ridiculous Veritasium video about Poynting vectors to me once again:
My previous post ranting about that video
I guess Youtube just wanted to remind me that he hasn't deleted that video yet. But the real surprise was in the comment section. A self-proclaimed "physics professor" by the name of [REDACTED] got thousands of likes by writing the following:

I teach physics at the University of California, San Diego, including this very topic. Within an hour of watching this, I set up the experiment, and got the result. I have photographs of the experimental setup, and of the oscilloscope traces. I discussed the results at length with a physics professor friend, and we agree on the explanation. In fact, the load gets the full voltage immediately; there is no ramp-up time, nor delay through the long wires (delay < 10 ns). This is fully consistent with transmission line theory that is well established for about a century. Dr. Muller's Veritasium series is great, but in this case, there are several claims that are incorrect, or at least misleading. There are many subtleties, and I cannot do them justice in a comment. I'd like to talk with Dr. Muller to clear these up. For reference, I have a BS in Electrical Engineering, a PhD in physics, and I am author of "[BOOK NAME REDACTED]", an upper-division/graduate quantum mechanics text supplement. This is my first Youtube comment ever.

And the most hilarious part was, the original comment was written with DOUBLE SPACE CHARACTERS following each sentence mark. Oh my!
Look, he says, I teach physics at a prestegious university, so I must be correct. I have photos of the experiment setup. Too bad this comment section is text-only, but you guys don't really have any reason to be suspicious. The load gets FULL VOLTAGE immediately, the same speed at which the debate about radiation/static fields gets thrown out of the window. All of this is consistent with transmission line theory. It's a laborious calculation but there's no need to ask about the details here. You know what's better? Another professor agreed with me. And if you feel double insurance is still not enough, let me just flex-tape my BS in EE to add a third layer of defence. Oh, and I forgot to mention, I wrote a book about QUANTUM MECHANICS, the subject that only a professional like me can handle. Well... no one actually cares to read that crappy little book that looks more like a bunch of lecture notes with ugly looking diagrams scattered here and there, but you get the point... OK, now I guess it's time for me to talk with the man behind Veritasium himself, because while he is right, he is not COMPLETELY right, as physics is always subtle...
Bruh, your failure in communication of REAL PHYSICS IDEAS (instead of your ego) is (1 l.y./1 m) times more miserable than your failure in understanding this problem. I know you don't have the talent to explain physics in vivid everyday language like Feynman did, but please at least make some attempt at doing so, professor?
