Much of 20th century economics was spent wrestling with this issue, and so we already have reliable long-run models that address increases in productivity and its effects on workers and wages, etc.  Do we then spend our time speculating on how things might be, and how our established base of knowledge might apply to that?  It's an interesting academic exercise, but I don't think it's one that should have everyone in a panic.
