Depending on what kind of society we will be living in the future, we'll be either happy or unhappy if the robots will take away majority of jobs. Typically efficiency on some sectors haven't removed the need of working force, just changed the jobs majority is doing. Compared to farming before and farming nowdays - you'll get more done with less people, but people still have lots of work to do.

However, working should not be the thing which defines what we are and are we worth anything. We as a people can find an enjoyable life without having to work 40 hours per week. One big question is though, why should we get any benefits from automation if we don't have any work ourselves? Should everybody without a proper job been left out from the society, or should they get all things for free for only living.

I can imagine the service sector will grow in the future. Even though we have service robots, we will find more people doing work in different services for other people (cleaning, gardening, hair dressing, massage, cooking, personal trainers etc.) when we can use automation in manufacturing processes.

Even though we can put a robot work in a factory faster and better than people do, it's a long way until a robot can be as good cook, gardener or personal trainer than we people are.
