This is good to know, for this video. Unfortunately, HN doesn't have a way to indicate this other than linking to a YouTube video; and in my experience very few YouTube videos are a superior way to absorb information than reading. To find that out, I'd have to either watch the video (negative expected value), or wait for a comment from someone like you -- and now that the latter has happened, perhaps I'll actually try to watch it. In the meantime, I do think there's value in providing information without a (sometimes literal) song and dance around it for those interested in learning over entertainment, on average.
