To me it seems Andrej Karpathy is like the new AI guru. In this post https://news.ycombinator.com/item?id=45619329 he predicted the future of AI a decade ahead. Do not get me wrong, I do think he is very knowledgable on the subject.
Is guru being used in some special sense here? Cuz Karpathy has been an AI luminary for at least 10 years. This post for instance taught RL to a whole generation https://karpathy.github.io/2016/05/31/rl/.
