Do you disagree with my take or think I’m missing Witt’s point? I’d be happy to hear from people who disagree with me.

Maybe the problem is that matrices are too general.

You can have very beautiful algorithms when you assume the matrices involved have a certain structure. You can even have that A*B == B*A, if A and B have a certain structure.
