I have enjoyed Karpathy's educational materials over the years, but somehow missed that he was involved with Tesla to this degree. This was a very insightful comment from 9 years ago on the topic:

> What this really reflects is that Tesla has painted itself into a corner. They've shipped vehicles with a weak sensor suite that's claimed to be sufficient to support self-driving, leaving the software for later. Tesla, unlike everybody else who's serious, doesn't have a LIDAR.

> Now, it's "later", their software demos are about where Google was in 2010, and Tesla has a big problem. This is a really hard problem to do with cameras alone. Deep learning is useful, but it's not magic, and it's not strong AI. No wonder their head of automatic driving quit. Karpathy may bail in a few months, once he realizes he's joined a death march.

Karpathy left in 2022. Turns out that the commenter, Animats, is John Nagle!
