Bootcamps have failed one after another. The most well known, Lambda, is even desperate enough they will "loan" you a new "grad" for free to try to get you to hire one [0]. And that's not even scratching the surface of what's wrong with bootcamps in general, like having instructors barely a few months ahead of students giving out lectures and grading assignments [1].
I can't say I've seen anyone out of a bootcamp that was a great hire. I guess these online coding schools might cater to motivated teenagers that are interesting in trying out CS before enrolling in a proper degree. But there's no money to be made there.
