I've been in one bootcamp class so my results may not be representative :-).

However I also get the feeling that being a developer has become more visible as well paying, in demand job similar to being lawyer was a decade or so ago. A lot of people wanted to be lawyers not because they were passionate about law but because they knew they could make a lot of money.

I get the impression that many people are drawn to boot camps by ads along the lines of "Make $XXk+ being a dev in X weeks" as opposed to being interested in the field.
