I can't think of many (any?) times I've agreed with Terry Moe, but that doesn't mean that the predictions he makes in this essay won't turn out to be accurate. He argues that an increased demand for technology will reduce demand for teachers, and fewer teachers means shrinking teachers' unions. Smaller unions will have less power, making it easier to implement more tech-centric reforms, which will reinforce a "more tech, fewer teachers" cycle.
