That is a weird algorithm. I don't think I would have come up with it given a million years

Right? Lol. Just looking at the promoted comment with the comparison between "textbook" 2x2 matrix multiplication versus Strassen's algorithm, I'm amazed at how he was able to achieve that efficiency improvement. I can see why nobody's made progress in 50 years. The 5x5 matrix algorithm which knocked off 3 steps from the older method must be insane.
