I'm not a big fan of this argument, which I see here too often. Really, truly motivated people don't need the Internet either. For any obstacle to learning, you can always say that it's not a problem because somebody, somewhere makes through.

I took exactly one Coursera course, Odersky's Scala course. But it was a great experience. Going through the material on a schedule with a bunch of other people got me to work harder than I would have on my own. I learned way more than I would have without the structure. Does that mean I wasn't "really motivated"? Sure, I guess. But the point of having educational institutions, rather than just giving everybody library cards and turning them loose, is to make it easy for a large number of people to learn.

So if it's suddenly harder for people to learn, even if they aren't judged truly worthy, I'm willing to call that a bad thing.
