The most beautiful mathematical lie ever told to first-year students. This "proof" cleverly cherry-picks the one miraculous case where matrix multiplication happens to be commutative, then declares victory with a smug Q.E.D. It's like finding the one vending machine that gives you two snacks for the price of one and declaring all vending machines are generous. Every mathematician viewing this just had a small aneurysm.
