As I see it, there are two "camps" of coders - those who code because they love to code and to solve problems, and those who code because it's a job.

The former solve problems, not because the boss is breathing down their neck but because the problem is interesting, and they will learn whatever needs to be learned to solve the problem. The latter look at a problem and go "but I wasn't taught this!", and despair.

Yes, those are hyperbolic examples, but are very real phenomena - we employ a lot of developers, and the ones who stick around are all from the former camp - the latter tend to wash out during probation.

I'm not at all saying that more people shouldn't learn to code, however I am saying that people who are learning to code because it's a career rather than as a vocation aren't doing themselves too many favours, as I would (and will) argue that the mentality of "how does this work? Don't know. I'll find out!" is absolutely core to being a coder, and those who have this mentality tend to gravitate towards code and other similar disciplines naturally.

There is of course the segment which comprises people with the aforementioned nous but who haven't had the opportunity to explore it, and these are the people for whom bootcamps are likely a brilliant idea, and a great bootstrap up into the industry - and I suppose this is reflected by the apparently very high drop-out rate seen.
