For a bootcamp to be profitable, the ideal model would seem to be that companies pay the bootcamp money to train developers for them. This means two sources of income, and allows the bootcamp to say with some confidence that n% of graduates get a job: trainees are likely to have high levels of motivation (in large part due to them putting down their own cash), and can be preselected for aptitude, then the companies they end up at are the ones who are connected to the bootcamp. Works out ok for all involved if that works, but only part of the chain has to break for it to become unfeasible.
But there aren’t actually that many jobs or companies who will pay, so the market for more than a few providers just isn’t there, as the article elides to. (Really good article btw)
Many [the huge majority?] look like they verge on scams to me anyway, same as a lot of for-profit colleges: expensive, low quality education with meaningless qualifications - if you’re a company that isn’t paying through the nose for trainees, then surely you’re going to prefer uni/college grads as they’re [statistically] easier to train to the needs of the business than non-grads with specific tech knowledge. Syntax is not the hard part of programming, and most seem to be teaching syntax.
