> Jobs taken by automation have always been replaced by jobs created by the economies resulted from automation.
Completely irrelevant.
Just because something happened in the past, doesn't mean it will happen in the future. Especially when you're talking with vague generalities (like you are) about something where the devil is in the details.
And then there are the personal effects, which comments like yours completely fail to address. If you lose your job and end up working at Walmart for a 10% the salary for the rest of your a career, while some other guy someplace else gets a new job that pays 75% your old one, is that a good outcome? People aren't fungible, especially when thinking about themselves.
