Agreed. QA is really helpful for anything UX/UIrelated (where the alternative is often experimentation, which really is only good for changing already existing things, and not necessarily ideal for new things). Or if something is so big, complex, and crusty like Windows, where it’d be a Sisyphean task to go back and add automated testing everywhere it could theoretically be useful, it’s a lot better as a stopgap than idealistically declaring you don’t need QA since in theory you could automate things (if you were willing to spend 2000 person-years on it).
