Ah yes,the story of Tesla: everything yesterday was crap,but everything tomorrow will be awesome.
In all seriousness, I like Karpathy and his work. Seems like a good guy. Not sure why you'd want to work to enrich a guy like Elon Musk though.
If you look at the alternative (Dieselgate), which is killing millions of people every year thanks to air pollution (sadly I'm highly affected by it, trying to not go near any polluted area is what my life is about at an age of 37), I'm happy for Elon Musk and I hope Tesla's mission will succeed as soon as it is possible.
