I have a career in software QA, and I got into it because I personally believed in QA and its significance to generating good software for people to use. Hell, I even worked relatively low-paying jobs because it was compensated by job satisfaction.
Then enshittification took hold of absolutely everything, QA started being flushed down the turlet in the interest of cutting costs (and, I suspect, out of management incompetence and lack of perspective), and now it feels as though my passion got stabbed.
I still thoroughly believe in QA as an essential part of software development, I still try to do the best I can not out of dedication to a job, but to my principle-based belief that QA does more good than it does harm when properly performed. But I seldom have the context to be able to do that, instead being stuck with menial shit and/or rushed projects which don't allow for a lot of testing.
