It's quite common in mathematics (and yes, physics) education, at least up through the first couple of years of university, to hear a student say, "I understood the lecture and what I read in the textbook, so I didn't bother to do the homework. I just don't understand why I failed the exam." Never mind what these fine fellows are talking about.

The folks who deliver the content of chat in youtube videos like this do not in general sample the same population as the audience that ticks the view-count of these videos.

Absolutely. Ed Witten is one of those who understands what he is talking about, the youtube clicks and probably most of the live audience, I guess, are not what I'm counting in the list of those who have a grasp. Authors of relevant work posted to the arXivs are more representative of those with "the knowledge" here but I don't keep a running total of them. Select Distinct from tblAuthors Order by LastName Ascending - or better Select Count(Distinct) From tblAuthors is not a query of the arXiv database I can make from here. :dunno:

There's no prerequisite for watching youtube vids about the frontiers of physics. It would be a big step even to know the difference between somebody who knows what hes's talking about (and who is talking about that) and somebody who is doing neither.
