Upon seeing the title I thought to myself "what's the point... karpathy already has an unbeatable series of videos on this" ... before seeing that this too was from him. I assume if one has been through zero-to-hero, this is going over stuff you already know, but will report back after watching.
Reporting back. As one may have guessed, it is light on technical details (no code for example) and serves as possibly an into to zero-to-hero. Some interesting insights into the near-future possibilities but nothing that can really be applied practically.
