This particular video is an exceptionally awesome video.
And so are his other neural net videos.
He keeps bringing you back to first principles, again and again, does not let a single doubt remain, and the code is very accessible and practical.
The intersection between those who can teach and those who truly understand the deepest essence of a subject is much smaller than we would hope. People like Feynman, Tanenbaum, Sussman, Susskind, and now Karpathy are exceedingly rare. Each of them is a gift for generations to come. So, when you find one whose style resonates with the way you think, I suggest watching their videos multiple times. :)
Thats cool but not exactly the same as reading text that was written to be consumed as text. I think a big part of the reason technical text is easier to digest is the way it's written, and not so much the medium.
Because the value isn't in just having raw reference material like complex code you just paste into your program. The value is in communicating ideas and understanding.
You don't need to skim through the 4 hour video long to see it's full of whys and hows and explanations and demonstrations that massively dwarf the blog post. It's basically a mini course.
Programming is an interactive process, so transcribing the video to text also removes a lot information. The video isn't just an audio form of what could've been a long text tutorial. You're watching someone do something.
