This agree with the post-2008 hollowing out of the middle theme - lots of of opportunities for high-IQ employment (coders) and the polar opposite: low-paid service workers and bedpan changers. It's like if you're IQ is not in the top quartile, go directly to the low-income, do not go pass go, do not collect $60-100k a year.
I'm very suspicious of the claim that these boot camps can turn novices into job-ready professionals in just 3 months. There's too much to learn and unless you're one of those high-IQ people who has an aptitude for math, as the example in the article, you won't be competent enough get a job and, to make things worse, you'll also be out $10,000.
Instead, if you're not smart enough to work in tech, take that $10k and buy Facebook, Google, Amazon or QQQ stock using in-the-money-call options. You can leverage 5-1 and make $30k a year from a $10k account doing this. The tech boom has much further to go. You don't need to be a member of Mensa to ride an obvious bull market trend.
