Real gains in educational technology will come from mediating in-person social interactions (focused on knowledge building rather than general purpose interactions, of course).

In many instances, the teacher actually knows what should be done to improve the learning of a student - but is logistically constrained from providing that level of service (Bloom's 2 sigma problem). The low hanging fruit is removing those constraints.

We will need better tools for understanding the knowledge/abilities of our students in a much more refined manner.
