Most people are not going to be able to follow the classes from MIT and Harvard. (Certainly, there are a lot of people who can't get into the schools who could follow the material just fine.) Remember, this material is already available in books, but that didn't put the universities out of business. But if you look at how many people are struggling with math classes and having to hire tutors, I don't think it is fair to assume that by watching videos from MIT lecturers would suddenly make it all make sense.
