Yes, you're right, if we take this course as standalone. When used alongside a more "traditional" course with applications, it's how it becomes very interesting

Yes, you're right, if we take this course as standalone. When used alongside a more "traditional" course with applications, it's how it becomes very interesting. You can easily feel guilty as a student when watching this, thinking you should focus on what's been specifically taught to you (during you 'official' lectures), and not on the conceptual ideas behind it. But it does make learning easier, and maybe encourages you to come back to the subject later, because you don't only see the subject as a tool anymore, and get a feeling a familiarity.
