It is being discussed as though it were ontologically novel, karpathy is saying it's something new and he is an authority, so to me there is something here that i am not seeing. I promise i am not trying to be a naysayer or poke holes, I am literally just trying to find out what the hell it is. I would install it but i don't want to install something without knowing what it does, and what is written in the docs is clear as mud.
