There's a catchphrase for this lecture. 'Why is this like this? It's true...' There are a lot of mistakes, so at some point the reliability drops a bit, so I have to look it up myself. It also has a positive effect;;; I recommend listening at 1.75~2x speed. It's not a well-polished lecture, but it's not boring overall, and there are a lot of summary parts, so I was able to finish it!
