MOOCs aren't a replacement for university, but a lot of people don't need a full university education in the first place. As I said in another comment, there is not a 1:1 mapping between university and education in either direction. Some people go to university and don't learn as much valuable stuff as they paid for or studied for, and some people learn valuable things without going to university. MOOCs address different needs: a lot of people who go to university and get humanities degrees and then work in non-humanities related fields didn't need a university education, and if they weren't required to do the signaling, could have benefited more by a broader, less in-depth education. Continuing education to keep up with advanced in your field, classes to teach you new skills you're interested in to just discover new things, etc. These are all important parts of an education, and university doesn't do them all that well.
