TeX is used in schools as Masaryk University, for many purposes: for writing theses, essays and papers by students, for teaching electronic publishing, literate programming, writing scientific papers, quizzes, slides by faculty, or for generating documents and web pages from university databases by university information system and its staff. TeX and related technologies are systematically supported and deployed at the Faculty of Informatics for more than two decades. In the paper we remind the support and projects we have realized in the past, we evaluate the outcomes, and discuss possible future deployment of TeX-related technologies. With the data of fithesis3 support and usage at MU we give arguments why the answer to repeated question from the title is definitely positive, at least for schools like ours.
