I get the impression that the business model for these bootcamps is largely the modeled after the one used in startup funding, where the bulk of the money will be made on the top 5-10% of the class. There's also likely some element of grabbing mind-share while they work to automate the process (plus, gathering data on who make profitable students). Eliminating the instructor will allow N to grow much higher than 150 per course and reduce costs dramatically.
