What is sad, is that there are already whole generations who think one must learn with an app, and are completely unaware of self-teaching textbooks from traditional publishers like Routledge, Assimil, Teach Yourself, etc. These books don’t work for everyone because learning styles are different, but they do work well for some segment of learners, yet with the decline of the physical bookshop, many young people may have never seen them.

(Hardcore linguaphiles are aware of these books, and have been one of the major demographics in the ebook filesharing scene that led to LibGen and Anna’s Archive. But I’m talking about the ordinary people you constantly see on e.g. Reddit who are just moving to another country, have to learn the language, and assume that one uses an app for that.)
