This article would have been better if the author had generated these kinds of diagrams, to show us what tensors the code was summing, and how. They could have easily used GPT to write the diagrammatic TiKz code, like they did for the fantasy style introduction.
But the diagrams would have illuminated the math, like real magic, while the fantasy writing didn't do any real magic because it only obfuscated the math. GPT does this when you don't give it the context to really explain things.
