I believe you're referring to lectures rather than a university degree. The arguments you're making are no different than the ones made by people saying traditional colleges would be gone in five years once MOOCs arrived. It's possible that things will change in a major way, but simply being able to watch a lecture from your home is neither new nor a substitute for a traditional four year college. (And note that the in-person lecturing part is actually really cheap - much cheaper than the same lectures online, and only a tiny percentage of the cost of running a university.)
