As someone who both interviewed bootcampers, and also partnered with a local bootcamp (IronYard) this is pretty much exactly my experience. The bootcamps can take someone who had an interest in programming before hand, and give them a fast leg up to get into programming professionally, and that's great. But the vast majority of people in these programs are just there because they heard you can make a lot of money as a programmer and have no real interest, or talent with programming, and it shows in their work.
