What loss.backward() actually does

As someone who has only had a very basic understanding of how backpropagation works, I found this to be really easy to follow along with, so thanks for that.

The article is also clearly entirely written, or at least drafted, by AI. The explanation is great so I'm not sure how much it matters. It does feel like the myriad of voices and writing styles on the Internet is slowly being drowned out, which makes me a bit sad.

Following up on my post on microcrad — many of you liked and supported the project, thank you for that — I published a long-form piece on automatic differentiation, where I explain backpropagation in simple terms so that everyone will (hopefully) be able to understand it. Questions/suggestions are welcome!
