3. The Hybrid Future: If you were to design the perfect learning system for a future student, what is the one core element you would take from online learning and the one core element you would take from in-person learning to include? Why are these two elements so important?

The classroom and classmates from in-person learning.  Then,  they can learn whatever they are into by teleporting to specific classrooms,  and have lessons that are suitable for their learning levels,  just like online learning.  And they can bring smart phones.

I wonder if they can use laptops.

回复 @啊啊是谁都对：Yes,  it is even better.
