Tesla self driving works. I don’t know if Karpathy deserves credit for that or not.

Tesla self driving kind of works. In a very similar way to how it kind of worked back in 2016. It's better than it was in 2016, don't get me wrong. But even today they haven't solved the problem and Karpathy left in 2022. And other companies notably have actually surpassed Tesla over that time. I don't think anyone could reasonably say he walked away in 2022 because he thought the job was finished.

Yes, no driver needed at all. Your Tesla makes money for you while you sleep at home.
