Yes, I agree. I was lucky enough to study where the current convenor of the Prolog ISO working group teaches, using a Prolog- and Elisp-based teleteaching environment that he has built over several decades. As in other disciplines, if you are elsewhere, you may have to move to get close to a master. This is not so unusual, is it? Vienna is a nice city for studying logic, and does attract students from all over the world!
