Somehow, the managerial class and the investor class insert themselves between the fruits of the labour and the engineers performing said labour. And if you think that's suddenly going to stop because the nature of the labour changes, then I think you're mistaken.
Enterprise structures rewards rent-seekers, because they are built by, and controlled by rent-seekers, utilizing disposable labour. The only way a power structure like that can be flipped, is through revolution. Or by forming your own company, out-competing these enterprises.
Every QA person I've worked with that is still in the industry has moved on to almost pure test automation. A few years ago that was more like 30% of the role. Now I rarely do almost any manually testing, except for exploratory purposes and to design the test plan. Also for certain things that don't automate well. These days I do more pure development than I have at any other point in my career. It's been super fun, but still quite a change. I've seen colleagues that were more the business analyst flavor of QA get pushed out of the industry when they couldn't/wouldn't adapt.
