I also don't mean to typecast anyone, but the author's profile on that site reads, "Full-stack dev @Radius, ex i-banker, @HackReactor grad, @UCBerkeley," so perhaps he thought his prior experience in an unrelated field or his alma mater should've helped him get a leg up over other entry-level devs.
Again, I don't mean to judge since my path to software development was also non-standard, but my first gig paid about $30k/year and I was grateful to even be given the opportunity with my inexperience.
I might be wrong, I don't have any direct experience with boot camps, but stripping dev skills down to just the minimal, core, practical skills needed to build a working prototype in the language-of-the-month seems like just the latest version of the same short-sightedness that has been plaguing businesses for years. Low-risk, long-term success will always come from building on experience, not "hacks" and short cuts. There will be exceptions/outliers, but they're just lucky, not a model to be copied.
