The best possibility I can see is the interactivity offered through conversational AI. We can scale STEM teaching to  massive scale with products like these. Immersive mediums like VR can keep the attention and interest of students for a longer time helping them learn better. If we add interactivity to better explain the subjects, we can automate classrooms to a large extent Preferably we'd end up with a future with only professors bu no teachers. 

Researchers will always be there expanding our knowledge and there will be people who are experts in subjects that would become the professors. Products like this (when enhanced) can work to take care of teaching students.
