It's the labs and the projects. Especially for engineering degrees, a good part of learning comes from shipping projects. I think it's where "everyone doing MOOC" falls short.
True, this is one thing that online course materials can't give you. But I also don't think a school like MIT has any real advantage in this respect over other schools. At least, not if the labs I had there are any indication; the materials we were given to work with were just as half-baked as anywhere else.
