In today's day and age, you are only limited by your own drive.
MOOC may seem like a boring enough thing, but really, it's demonstrative of one of the most profound changes that may have ever happened ever: freedom of information. Human beings are, in general, generating more data than ever. Instagram, facebook, twitter-- all of this adds up to be more 1s and 0s than you can imagine.
At the same time, information and knowledge is becoming more and more open. MOOC, or massive online open courses, are a beautiful example of this. You can pop into iTunes and learn how to create an iPhone application from a Stanford professor-- for free. This is but one of many classes that can be taken online!
The point is this: a MOOC is a massive open online course, and no one has any excuse not to be educated anymore, I mean, unless you have to work and like feed a family, and stuff. But if you don't, you can be a genius-- for no money, and really, without even leaving your desk except for more Mountain Dew.
