Jobs as we know them have only been around for 500 or so years. There have been other ways of living beforehand and I expect we'll be about to figure another way in the near future. The only real argument I see for keeping jobs around even when human labor isn't needed anymore is the protestant moralistic one, and I don't buy that one.
The abstract occupations of most people for all the thousands years of advanced society (marked by the ability to accumulate and hoard food or other kinds of wealth) have been marked by subjugation in service to some elite classes. Naturally some people are a bit concerned about their future and are not content to just stumble/bumble into the future and see what kinds of “ways of living” the powers that be have in store for them.
