No idea who the presenter is, have seen a couple of his videos before. He reminded me of the videos we had to watch at school as a very young child and then the Open University programs that used to be shown over night for people to record. These were often people with beards in white lab coats (or at least they were in the comedy sketches).
My point is that his boring/non-sensational style is refreshing for the Internet and far more useful and educational. One I watched was on the use of locking diffs and his little model cars

I don't know if he is right or wrong on all his presentations but they are clear and understandable
