Came here to post this. Great suggestion. What I like about these videos too is that it lets you start at the end. Depending on your preferred approach to learning this makes way more sense (to me at least).
1. Watch Karpathy do some of the craziest stuff you've ever seen.
2. Go "how in the world could that be possible"
3. Then you are armed with appropriate questions to start working back through other materials in the original post as needed.
