For people who are already in academia and want to be more academic? I don't get it. This notion that Masters are for academia is so contrary to my experience altogether. They are not even associated with research, in my experience. What I have seen is: * BSc: General professionals. * MSc: More specialized professionals. * PhD: Baseline for research, but more often than not just doing even more specialized work than folks with MSc. * Postdocs: Actual researchers, including but not limited to academic careers.
