I believe that it is inevitable; we will keep creating and advancing. Jobs will be taken over, and if time allows it, we will have no jobs, Eventually, presuming the Jesus will not return and take back his kingdom, we will be like WALL-E. Fat, in floating chairs, and the computers will do it all. We create what we create to make our lives easier. If we fully create the ultimate easy and lazy environment, it's possible that a good percentage of the population will no longer work, walk, and even possible eat. We may take a pill that makes us never starve again. The extent to technology, is none. This is hypothetical of course, there will always be the group of people who enjoy work, exercise, and playing. Children are hyper, they run around everywhere. However I believe God will destroy all human creation and take back his kingdom before we fully have no jobs or close to no jobs. Possibly way before time comes to that much advancement.
