I thought Karpathy's contribution to the presentation was an excellent technical summary of what Tesla is trying to do. It clarified a lot of things for me what they're doing with Autopilot. Up until a few days ago my attempts at scrutinizing autopilot have been limited to little snippets of information here and there, rumours, and guesswork.

Bullshitting and wankery doesn't come naturally to Karpathy so the few spots where he was under pressure to do as much stood out like a sore thumb.
