Take this for what it is worth, my opinion may be somewhat biased because I have a CS degree.
IMO, the main benefit of coding-bootcamp types of programs is that you will get to figure out pretty quickly if you hate writing code or not. I suppose that's worth something, but considering you stated you had 5k saved and that wasn't going to cover it, it must cost more than that. I'm not sure what the specifics of this particular program may be but to me anyway that seems like a ton of money to spend on something to find out if you like it or not.
The other thing that doesn't square with my experience is the money thing. This isn't just your comments, by the way, this is something I read on the internet a lot. I realize that salaries in certain specific areas or industries can be through the roof, and obviously I don't know the situation of the individuals you cite. Depending on specifics, maybe that's all true. What I can say, however, is that I've been doing this for 15 years, and worked for a number of different companies ranging from startups to fortune 500 size, in a bunch of different industries and in both HCOL and LCOL areas and I know this: If someone came to an interview at any of the places I have worked, asking for 90$k with coding bootcamp as their sole experience, they'd be laughed out of the building. It is true that the market is hot right now (I actually just changed jobs, my resume was on Monster for about a week, and I still get calls almost daily), but the fact of the matter is that earning big $$$ is a lot harder than people who are not in the industry make it sound. Companies that hand out 100k+ jobs to relatively inexperienced developers... I dunno, I'm sure they exist but not anywhere I've ever been. It's a tough job and people who earn that kind of money (for any extended period, anyway) provide a lot of value by knowing a ton of stuff.
None of this is meant to be discouraging, by the way. It is absolutely true that there are many different ways to get into this industry, and I don't know that one is more "right" than any other. It is a more egalitarian field than most. I hope you end up enjoying writing code, because it can be a great career and frankly we need more developers that know what they're doing.
I guess my advice would be to forget about money (salary) entirely for now. Try and get your foot in the door by landing a low level development position somewhere, and when that happens try to absorb as much as you can from the people around you. That experience will be worth far, far more than any class you are going to take anywhere and the things you will learn will help push you towards the numbers you are talking about. If coding bootcamp is the way you find your way in, that's great but for 5k+ I'd want to be pretty sure that was going to end in employment. For me, that'd be a tough call... I would think 5k would get you pretty far taking normal classes at a local / community college (and by the way, if you end up with a CS degree, after your first job nobody is going to care where it came from unless it's MIT or Stanford or something like that).
I wish you the best of luck... if you enjoy the work it is a great career.
