As someone in this group, I'd have to disagree with you.
I work in a life sci research setting, and am usually the only person with any programming knowledge or experience whatsoever. In research, "it works," is generally the only quality control placed on bespoke software. I'm capable of writing working programs to perform simple tasks & do on a regular basis, but I could not begin to write a large web application using best industry practices. I've also never spoken at length with other programmers regarding the problems I'm facing, and as such, I would have a significant degree of difficulty discussing conceptual frameworks with a team.
Having spoken to a few people who attended these schools, it seems that they have a thing or two to teach someone like me.
Perhaps it's not worth $10k, but I think that's a separate argument.
