Oh no even now there is plenty of use for it outside of AI training. Just think of all the schools in villages all around the world that don't have access to the internet or have a very limited connection. I've worked with folks that would setup local "wikipedia servers" for schools so that kids could access Wikipedia via a local network connection. In other setups they just download all of wikipedia to a set of laptops and you use one of the offline readers to browse it.

This is essentially the modern version of having a library of encyclopedias.
