As someone who much prefers reading over watching videos, do you think I would miss much by just going through the book in the github repo? Or are those notebooks mainly supplemental to the videos.
I'd say it's the other way around - the videos are kinda supplemental to the book. The book has a lot more content, but doesn't have the interactive explanations in the course. Also the book is a couple of years old so is missing the more recent developments (but the principles haven't changed).
