This would have made, perhaps, a decent article about the benefits of sticking to it and persevering in teaching yourself stuff, but the over-emphasis on Codecademy takes away from it.

However, I don't think they (or anyone) would argue that coding instruction is sufficient to revive the possibly long-gone "American Dream". It's a small piece of the puzzle.

The real problem is that while there's infinite demand for solving problems and making the world better, most people don't get jobs that provide access to that infinite demand. Those jobs only exist if you have savings to go off on your own. Otherwise, you're a subordinate supporting someone else's career, and demand for subordinate labor is going toward zero, due to technology. It's so low that if you're over 40, you're probably priced out of those kinds of jobs unless you're an executive.

Most people need to work in those subordinate jobs (to get savings and credibility) before they can create their own jobs, but those subordinate jobs are now being eaten by machines, which are just much better at reliable, cheap subordination than any human.

The gap between what the world needs (problem solving) and what people can get steady income to do (subordinate labor) has reached an unacceptable level, and it's now tearing the economy apart and shutting what used to be a bidirectionally reliable labor market down.

Providing easy access to coding resources is an admirable step in the right direction, but this is a huge problem and it's not going to be solved by one website. Given that universities with trillions of dollars (as a set) in endowments have failed to solve it, I think that this problem is going to be around for a while.
