Idk, these kinda videos rub me the wrong way. In any given population you will have dumb asses. You can ask enough people a question and find people who don't know the answer. Then only publish the dumb videos to make the whole group look dumb. I remember people doing it to millennials like 8 years ago when they were in college. But you could ask the same question to random college people and they would recite who text books. The YouTubers would ignore anybody who gave good answers. The UD education system is far from best but we generally are taught the contents. It's hard not to know where they all are by fourth grade.
