College debt is getting out of control. I could see MOOCs cannibalizing some lower tier options, like University of Phoenix, which IMO would be a good thing. But I don’t think Harvard’s going anywhere. To become more popular, MOOCs need to do a better job of marketing to employers that their credentials are just as good as some lower or mid-tier state university. Some MOOCs are already doing this, like Udacity with their plans for offline proctoring. For now, most MOOCs are basically TIVO for lectures.
