@akhilrao all that said, there are lots of circumstances where "cost disease" shouldn't be taken as a disease at all. for example, a teacher of a small class is, superficially, a cost disease example: holding class sizes and learning pace roughly constant, productivity seems not to have increased. but we would not want productivity in that sense to increase, because the actual value comes from a not-scalable human connection, not anything a MOOC can provide. 2/
