At some point I imagine various fields of knowledge will advance so quickly that university degrees will be outdated before the students graduate, for instance, medical knowledge. That means we either require either faster (and therefore less in-depth) degrees, constant study (like a more extreme version of the current case) or some new method of creating doctors.

PS - New methods for doctor creation may be up to other doctors.
PPS - Or artificial intelligence researchers.
