They said bootcamps don't scale, not that education or schools as a whole doesn't scale. And your solution of raising the entry requirements so only people who can teach themselves can attend is proving their point. Someone who can teach themself isn't going to pay to go to a bootcamp, but people who want to switch careers and can't figure it out without help, will.

I mentioned two solutions, raising entry standards and providing greater support. There are people who can teach themselves. There are very few people who can teach themselves as fast and as well in a self-directed environment as they can learn with a real curriculum and some feedback on their work. If you are confident you can teach yourself in two years or reach the same level of employability after nine months of Lambda School the latter looks pretty good even at $30K once you get a job paying over $50K.
