It (work) / They (jobs) will be gone. And that should not be a thing to worry about as long as the right politicians are voted into office. Currently governments apply taxes mostly on work and money spent. When those are no longer viable options they'll have to tax something else to keep the nation running. Production and property. Or they'll have to (shudder) privatize. They'll need to distribute enough wealth or risk anarchy. Whether they take the 'left' or the 'right' road.
Those with creative ideas and the will to execute them will still earn. Those depending on cheap/manual/easily replaceable labor are better off -not- breaking their backs and have a nice walk through the park (or 'couch potato' some torrents) instead. Talking about breaking backs, as that's a health risk an employer has to insure against, I foresee such workers in the future becoming a liability even if they offer their services for free. Robot labor will eventually become cheaper than human labor offered voluntarily and 'without cost', unless, as a society, we accept people being worked to death.
That's why lowering the minimum wage is a dead-end road. Whether you're a 'commie' or a 'capitalist', or anything in between, changing the minimum wage to anything other than 'if you work for reasonable hours/week you can live off of that, have some small luxuries and support a modes family', will do more harm than good. When minimum wage is too low, you'll have people starving and not enough consumption to keep the economy going. When minimum wage is too high, people working above and beyond what's normal (those that used to earn a higher wage) will stop putting in effort to keep progress going because they can 'earn' the same 'doing nothing'.
As such, minimum wage is not and should never be meant to indicate the value of the lowest paying jobs employers are willing to not automate/offshore away. Because that will lead to distopia. It's an indication of what we, as society, think a human being should earn at least (and thus be able to consume in equal value), as a member of that same society. Whether the job is adding that value to society or not.
I foresee a lot of new hobbies in the not too distant future, manual labor being one of them. Maybe some of them will even become sports, so the really talented can earn money going that route. The others will be glad 'modern' humans will never have to do that anymore.
Who wants to manually wave cloth, pull a plough, delve coal using only a pick-ax or even operate a switchboard... or any of the other jobs that have disappeared because mechanical/automated labor is lots and lots cheaper than paying some human workers a decent wage?
