1) I think it really depends on how you define "robots". If you defined robots to include servers, many jobs have already been taken.
2) Transitions are slow. Jobs our parents knew don't exist any longer. But it won't happen faster than that.
3) People move on and learn new things. It's great to get rid of receptive tasks that a computer/robots can do. It is liberating. No one wants to wash their dishes or clothes by hand these days.
