I've always had a problem with the phrase "learn to code." It assumes just being able to encode a thought in a programming language is good enough. It isn't. Having a thought worth encoding is what separates "super junior" devs from ones who actually know what they're doing. Being able to formulate worthwhile, efficient solution to problems takes more than 12 weeks to learn. There's no substitute for time and experience. One of the reasons traditional college works well is that it forces you to spend a long period (~4 years) immersed in the discipline: thinking and reasoning about computer problems. Do you come away from that with everything you'll need to make production software? No. That still necessitates experience. You will, however, be able to learn from that experience more efficiently because you've got the fundamentals.

I work at a large company that absorbs tons of MIS/CIS grads. The non-CS grads that excel are the ones that are constantly hungry to teach themselves new things but for the most part they suck compared to the CS people. I can only imagine how much worse these bootcamp folks must be.
