What insight did you gain from back propagation that you didn't have from just the formula of the chain rule?

What clicked for me was drawing the chain rule as a graph. When I was in school I just applied the chain rule without thinking about it. I really didn't mean this to be some deep insight or anything. Just an anecdotal comment.

Ah makes sense, I was thinking there was some deeper insight I was missing. Thanks!
