This comment inspires a more philosophical observation. I tend to notice that it's an illusion that education exists for the sole purpose of preparing human labor for future jobs. Partially it does, but another part is fixing progress consequences. Imagine you traveled to the past where 99% of workers were agricultural ones and explained that there would be a future when only 10% is required to fulfill needs for food for others. They obviously complain that it would be terrible because so many jobs would be lost and so on. But humanity is great at inventing new occupations. Fast forward from the past to present. We have many schools, universities where there are many paid jobs (tutors, clerks, management) and many unpaid occupations (pupils, students). In our hypothetical past only a tiny fraction of the population could afford to belong to these two categories. And the latter can afford to be unpaid because progress allows their parents to pay for them in order for them to be occupied without a paid job.
