I would suggest instead that we focus on two other problems with bootcamps, one mentioned in the article and one not:
* As the article suggests, bootcamps are probably not as effective at placing graduates as they'd like us to believe. There is a stigma to bootcamps, which is telling, because there's no such stigma for self-taught programmers. That may be because bootcamps aren't effective, or it may be because of correctable market inefficiencies that someone will make money arbitraging out. I'd guess it's a little of both.
* It's probably not easy to staff a bootcamp. They don't pay instructors particularly well. If you can effectively train 70% of a cohort of students well enough to secure professional employment, there's a lot of other stuff you can do in this field. To make the business work, bootcamps have to balance the willingness of students to pay with the salary demands of instructors, while retaining enough to grow. Maybe that's just hard to do.
