In my opinion, vast swathes of many college programs are currently completely replaceable by online courses. The only thing preventing this from being acceptable to employers is the college mystique. If the college mystique gets punctured... and I can't think of a faster way than to jack the price up beyond what anybody can afford... and it becomes acceptable to have an online degree, what happens to conventional colleges then? On a pure dollar-for-dollar comparison, the online colleges will kill conventional colleges for value.
You might find this hard to believe if you went to college and took some actually non-trivial course, such as in engineering. Leave engineering and the hard sciences, though, and a lot of courses are just mind-bogglingly trivial to pass. As part of a learning content management system I worked on while in school, I once had to debug a junior-level marketing course, so I took some of the pop quizzes from the middle of the course. I got 7/10 and 8/10... and there are people who actually attended the course who didn't do that well.
I shouldn't be able to score 8/10 on a pop quiz for a junior level course in an unrelated discipline. There probably wasn't a single 300-level engineering or hard science course I could have done that on. But... not everybody going to college are getting degrees like that. (And, ultimately, quite a lot of even the hard courses could be moved online with little loss...)
(I said "vast swathes of many college programs" very carefully. There are yet some programs that aren't very replaceable, and will always have a physical component. Another way for a college to get around this is to make their courses less able to be taken remotely, although as technology marches on it gets harder and harder to imagine what exact form that would take... A lot of people complain about various problems with online courses vs. real courses but I find myself wondering how much of that is truly fundamental, vs. how much of that could be fixed with better technology.)
I'm not sure I could agree with "useless", but "poor value" and "easily replaceable with a cheaper but just-as-good-maybe-better substitute" I sure could agree with.
If some startup could get past the accreditation hurdle...
