Well I was in CS about 30 years ago at this point so I am talking out of my old crusty butt but I recall that while we did fancy FP things in lisp and APL or whatever, the software we wrote was still on a very small scale compared to what you work on once you get into a job and inherit a huge codebase. I think the term "does something useful" is the point of contention on this. We wrote things like, take a document and word wrap all the paragraphs. That is useful. But that's not really a real-world enterprise level assignment. Again, that's the crusty old perpsective informing me on this, your sister could be building out a self-driving car platform for all I know in Haskell, good on them !
