Building something from scratch forces learners to confront gaps in their understanding and, according to Andrej Karpathy, leads to deeper understanding.

“that part is not there yet i would love to actually like add that probably later this week or something in some way like either it's a it's probably a video or something like that but um but maybe roughly speaking that's what i would try to do is build the stuff yourself uh but don't allow yourself copy paste i do think that there's two types of knowledge almost like there's the high level surface knowledge but the thing is that when you actually build something from scratch you're forced to come to terms”

“the terms with what you don't actually understand and you don't know that you don't understand it and”

“it always leads to a deeper understanding and it's like just the only way to to build is like if I can't build it I don't understand it is that a finance quote I believe or something along those lines”
