Sebastian is using one of those electronic pens to write in this course. I'm not sure how exactly this works, but his hand is transparent in such a way that it never blocks the text (I didn't notice this immediately, it all seemed very natural). I watched the first few videos of the Fall AI class--this is far better than that approach. I'm not sure how they'll deal with errors--too soon to tell. So far Sebastian has been very good about not using jargon without introducing it--in fact he's been extremely empathetic in this regard. Moreover, so far the format of the course has changed to focusing on solving the specific problem (like robot localization) and then afterwards introducing the formal ideas, like Bayes' theorem. Its much better than the videos I saw from the first AI course. I think you're right that sometimes doers are not great teachers, but I am convinced that you should give Thrun another shot.
