Coding Bootcamps are good to interest children in software careers. They are good as contests to pit teams against each other in professional show-downs.
They are not a substitute in any way for a software engineering degree.
The entire basis of the article is false. in particular their assertion that "About a third of STEM employees don’t have any college degree at all" is laughable. I guess if you widen the definition of STEM wide enough you get to include sanitation engineers.
