Just started watching and Andrej is an excellent "thingexplainer". His in-depth knowledge of the underlying atoms/bits comes through. As an extra benefit to watching his lecture using the https://karpathy.ai/zero-to-hero.html is the link to his "discord chat". This is a very active community and Andrej is very active there. So feel free to watch lectures, cry through the assignments and come to the discord with questions. And they will be answered.
