I think he means that ‶guy who knows to code″ used to be a statistically strong marker of ‶tinkering guys with a potential″, which is less true now that IT is now socially internationally perceived as a high-reward career, hence a one where people may go either because they like it, or just because they want to make stacks.

Boot camps take the “seems to be passionate about coding in their free time” signals and help their students try to fit those signals by encouraging them to build personal projects on GitHub etc. This somewhat dilutes the ability of recruiters to check off “has some GitHub projects” as a heuristic, however useful that was to begin with.

>But the vast majority of people who go to programming bootcamps don't get rich quickly, or rich at all. Same with most people in the world who practice medicine or law

but they do get a reasonable shot at a middle class lifestyle with potential to do really well at some point.

That's better than a lot of career paths give you nowadays.

Of course not, but that's the sales pitch, isn't it?
