This seems overly-pessimistic (especially the 5, 10, or 20 year horizon; I don't see nearly enough infrastructure or social organization in place), but most likely contains a kernel of truth. Once upon a time, all clothing was hand-made and custom fit. Custom tailoring became a high-end trade for those who could afford it when mass-produced clothing became "good enough". Perhaps learning will take a similar route...
Whenever a college student asks me, a veteran high-school English educator, about the prospects of becoming a public-school teacher, I never think it’s enough to say that the role is shifting from "content expert" to "curriculum facilitator." Instead, I describe what I think the public-school classroom will look like in 20 years, with a large, fantastic computer screen at the front, streaming one of the nation’s most engaging, informative lessons available on a particular topic. The "virtual class" will be introduced, guided, and curated by one of the country’s best teachers (a.k.a. a "super-teacher"), and it will include professionally produced footage of current events, relevant excerpts from powerful TedTalks, interactive games students can play against other students nationwide, and a formal assessment that the computer will immediately score and record.
I tell this college student that in each classroom, there will be a local teacher-facilitator (called a "tech") to make sure that the equipment works and the students behave. Since the "tech" won’t require the extensive education and training of today’s teachers, the teacher’s union will fall apart, and that "tech" will earn about $15 an hour to facilitate a class of what could include over 50 students. This new progressive system will be justified and supported by the American public for several reasons: Each lesson will be among the most interesting and efficient lessons in the world; millions of dollars will be saved in reduced teacher salaries; the "techs" can specialize in classroom management; performance data will be standardized and immediately produced (and therefore "individualized"); and the country will finally achieve equity in its public school system.
