The future of education

I just started taking CS 50 at Harvard College.  I have all of the lecture notes, video of the class sessions, the problem sets and the quizzes.  The amazing thing is the course cost me nothing.  Welcome to open courseware.  This is where colleges and universities create course content and share it freely across the internet.  The classes won't give you course credit, but will provide you with the same knowledge as the student who pays $20,000 a year in tuition.  What does this mean for the future of education?  I don't know, but I have a class to watch.  I'm trying to learn to program.  If you want more information on open courseware please go to OCW Consortium
