How long is a well-run bootcamp? Getting a CS degree takes many, many hours of course work, plus typically a bunch of non-CS course work. I'd think a college grad would (should?) be much better rounded. That depends a lot on the quality of their CS program, obviously. What you describe college grads doing sounds more like a 1-semester high school CS class to me.
A CS degree takes 4 years, two of which are usually not related to CS at all. Still valuable stuff to learn, but also a lot of bootcamp students might already have a degree in another field so they already have the gen eds out of the way. The remaining stuff in a CS degree, only some of it will ever be directly relevant to what most programming jobs entail. Sure, you may end up in a job where compiler design comes in handy, but most people won't. If you focus on just the parts that are going to be relevant to most programming jobs, you may need a program a bit longer than the current bootcamps but much shorter than 2 years of CS classes.
If I were put in charge, I would make it 6 months long. I could definitely teach people how to write coherently designed CRUD apps in 6 months (ie. 95% of all programming businesses in the wild).
