For as long as the occupation or the work can be divided into routine tasks that does not require intelligence, that work can be replaced.
Take for example my scenario at work: I want to move mountains and can get times more work done than I am able to do now. How do we do it? Extract the routine tasks and assign it to a computer, or to someone who can follow directions. That would free me to do more inordinate things. Maybe then I can move mountains. Also, become more managerial in my tasks with my computer serving as my subordinate. That is another way of growing. Lastly, diversify my newly found time to more ambitious projects where roads and directions have yet to be paved.
