> I'll stick up for coding bootcamps as a general concept
Sure, and similarly there isn't anything inherently wrong with for-profit universities: You can certainly find people who excelled in an environment like DeVry and don't regret their decision to attend.
Over time one can expect that the "cream will rise to the top" and good bootcamps will have a certain reputation associated with them. Similar to for-profit universities. Still, I hope it goes without saying that many of the same concerns about for-profit universities also apply to coding bootcamps.
> I do think that the credential is important.
Why? What does the credential prove in this case?
> sure enough, three months later she got a job at $110k coding the consumer website for a bank.
That's great! I'm happy for her. Still, I hope that sentence gives you (and her) some pause for concern.
If three months is enough time to train someone for a $110k job, I would suggest that job is unlikely to remain paying $110k in the foreseeable future. It's hard to think of other professions that pay so well for so little investment. The supply can (and will) increase precipitously to match the demand, and salaries will drop precipitously.
For a recent example, see the recent glut of law students and freshly-minted lawyers making a pittance. There are quite a few parallels between that scenario and the current one facing software developers, except that law school is even more of an investment than coding bootcamps.
> at least be in a place where you might see another $50k/year over the next 5-10 years
That's my point though: I don't think that's likely. Maybe over 5, but it seems unlikely that 10 years from now she'll be making $160k. I'm suggesting that those kinds of salaries will be reserved for people working in specialized fields, not people doing basic web development.
For a more realistic future salary, I'd say look at developer salaries in places like Canada, or much of western Europe (where $60k/year a year is probably much more realistic than $110k).
> Google isn't going to hire a bootcamp grad, but they also almost certainly won't hire an autodidact
Google absolutely hires autodidacts. I know a few of them. Clichés about "non-Stanford students need not apply" aside, Google just hires smart people. Smart people don't always have degrees or certificates.
