Seeing current advancements in the field of gamification, I am almost certain that at some point we will be able to teach children in a motivational and enjoyable way things they actually need for their future life and career - even catering to the unique differences between every single one of them.
I am not of the opinion that we need AI or anything fancy for that which does not already exist today, however we might need to study humans, their emotions, how they act and what they like more, in order to make educated guesses about how to teach and what to teach.
Just to make an example, while I had "Educational Arts" at school, which taught me how to use techniques to create a scenery from randomness, it's not something I enjoyed or actually need. I would have loved to learn how to draw characters, or imitate materials, or create 3D bodies. That would have been useful and just as much "art" and "educational" as what we did. I would expect a future program to be able to determine, from what I like and how I act, to teach me the right tools and guide me towards new and exciting tasks I might enjoy and with which I will be able to earn money in the future.
