It is good in the sense that billions of people will have access to world-class lecturers and that local mediocrity will lose its (often foul, sometimes downright evil) fiefdoms. Today, even very good universities count themselves lucky if they can get top-notch professors for a third of the courses that they have to provide. In the future, it will be top-notch for everyone. On the downside, diversity of opinion is likely to suffer: the fewer the lecturers, the fewer the opinions.
When all is said and done, following the present uncertain, transitional era, with the advent of online teaching higher education will finally come to terms with market principles, in a way that need not sacrifice quality. The best lectures would become available to all, albeit with a premium for better tutorship/assessment. Top lecturers would match the commercialisation and high earnings of top researchers, while rising global demand for higher education would secure the future of tutors/assessors. The only challenge will be how to preserve plurality, once teaching is concentrated in the hands of the superlecturers. It is likely, however, that this challenge will be met by the openness of the internet (provided it stays open in the future) and the existence of a multitude of local tutors, who will inevitably put their own mark on the centrally approved course materials. University tutors have proven themselves capable, time and again, to evade even the toughest totalitarianism; faced with a financial incentive to keep their franchises going, the course franchisors are likely to exercise only light censorship. As research becomes ever more separated from teaching and as research results become ever more widely available, it is unlikely that superlecturers will become the new "Ayatollahs."
