Sounds very familiar although I worked for a company, which produced materials for learning and teaching like books. I once argued that the Quark-files the company had worth of in thousands and thousands paid work hours from script writers to layout designers, all that possibly reusable, weren't worth any work hours while upgrading up away from previous files but only to have the latest and greatest software. Well the files' ownership changed to a big corporation later, for which I didn't give a penny.
However Quark-files make an exception. The end product of publishing still finds its way to paper many times, on paper it gets distributed and can't be in such a stranglehold of file formats, DRM, cloud services etc as digital information. As the famous clause goes "information wants to be free" it is still too easy to forget that the freedom has independence coded into it. And here everyone knows, what free code is, but it seems like it hasn't yet produced as free information as paper still does - although there is arguably more restrictions printed on paper nowadays.
Seeing the current challenges and threads in future in maintaining free information, I'm glad that paper as medium was invented first in humankind. At least the paper offers some reference. It seems to be good business to reinvent everything digitally, so digital information is doomed. It is much cheaper and effortless to me give space to my books and carry them while moving (except I'll do everything in my power to not move anymore) than do the required work to maintain digital information usable and accessible.
