@pastanaga - Unfortunately, I don't think they will stop with the horrible jobs. I think assembly line robots will end up being the future and put a lot of humans out of work.
I mean, a 3D printer is essentially a small version of an assembly line robot and they are going to become more and more popular as time goes on. As they rise in popularity, the industries they replace will collapse and people will lose income. It's kind of scary thinking about it.
