It does... If you want to develop new methods that use GA concepts, or you want more perspective on geometric notions. GA is not more general than linear algebra... i think of it as sitting between vector algebra (which often is too limited) and linear algebra (which is often too general). All GA expressions are in LA (though they may be much uglier), not all LA expressions are in GA.
