Of course, I also believe that there will be more and more routine duties to be replaced and automated in the future. However, there exists some duties that cannot be replaced.
In the context of doctors, for example, there always exists some "grey" areas in medical diagnosis that cannot be automated, partly because of incomplete/incorrect understanding of medical issues. This is how an expert stands (i.e. "what if" no rule). The same thing applies to all walks of life.
For the context of enginnering work (such as IT work), the design of a system includes not only its functional components, but also does it represent an artistic work. Take programming as an example. There exists an infinite number of ways for developing a computer program. How it is structured and presented can somewhat be an art!
For the context of education, teachers should not simply convey knowledge as well as learning techniques to students. More importantly, should they show with passions and guide with personal values on the abilities for differentiating (ethical) rights and wrongs, propers and impropers, as well as making judgements whenever objectivity does not exist (that would normally be the case)!!!
Furthermore, the current AI is developed by human beings. As expected, it would be difficult to "think out of the boxes" that can surprise those contibuted to the field, except for computational and storage efficiencies. That is, its capability would be expected to be bounded by those of the contributors.
