Claude codes faster than I do, by a significant factor. Claude can hold more details in its "mind" than I can -- again by a significant factor.
But Claude cannot hold the big picture in it's mind. It doesn't really even understand the concept of a big picture. Architecture is likely beyond it's capacity.
And although Claude appreciates the value of refactoring, it shows no inclination to acquire that value for itself. It has no sense of self preservation. It does not look ahead and foresee the disaster it is creating.
