I've gotten one hell of a return from my BSc. EE. Thankfully it's not being devalued, and as far as ROI goes, wow. Was it easy for me? F--k no. Things that are worthwhile rarely are easy.
Anyone who thinks these bootcamps are a substitute for theory training is a fool. They can make a great way to leverage that core knowledge, though. They're also great for churning out code monkeys. I don't want to be a monkey.
You know what's a substitute, though? -Free- books and training online on those academic topics. Marry that with a good, accredited lab work program and you're going to be onto something; I suspect, however, this will be targeted at a lower common denominator.
Democratizing forces will come to higher education as there's HUGE market inefficiencies there created by an artificial barrier. It's just a matter of time, or like I've said before, one of the Ivy league institutions to offer real credit in an online environment. Right now it's a big game of chicken to see who blinks first.
