Interestingly, when I saw that I figured this channel for a goner because he was going to turn to the darkside, but quite contrary to expectations I feel like his channel has actually blossomed since then. His older videos are fine, but often just explaining concepts that you can find a lot of other explanations on, but some of his recent videos have rocked the boat even among physicists and IMHO he was ultimately proved to be correct for them. I particularly point at his videos about how nobody has measured the one-way speed of light ( https://www.youtube.com/watch?v=pTn6Ewhb27k ), which was well-known among people very very deep in the field of relativity but not very well known outside of that (even amongst physicists in other fields, let alone lay people) and the electricity videos he's done in the last year (https://www.youtube.com/watch?v=bHIhgxav9LY , https://www.youtube.com/watch?v=oI_X2cMHNe0 ) which attracted a whole whackload of "debunking" videos, which were themselves wrong (the best "bunking" video, if I may call it that, is probably AlphaPheonix's: https://www.youtube.com/watch?v=2Vrhk5OjBP8 , since he actually set up the experiment, albeit on a smaller scale).
They aren't all of that caliber, but the knot theory video was very good too and not something I've seen a hundred times elsewhere, and the airships video that preceded that one clearly had a high degree of research put into it beyond just the hype.
He actually acknowledges this in an earlier video, where he mentions that that the YouTube algorithm no longer gave him much of an audience with his more natural-form videos, and he explicitly said that he would try a few clickbaitey titles to feed the algorithm.
