To be fair, software engineers are in the kind of luxurious position where we can actually say something like:
I don’t enjoy doing this job so I won’t do it.
I don’t think that’s true for the majority of people, who just happen to do a specific job because they’ve been trained for it and it pays the bills.
That's cool, but testing roles exist throughout the industry and some people choose QA as a career.
I wouldn't want to be an IT support specialist, it sounds like a boring job to me, but that doesn't mean that there aren't a million career support specialists employed by trillion dollar companies like Apple.
I'm sure people would line up to be paid well to work on Apple's QA even if you wouldn't.
