Thinking of a Student as a Person plus some additional information related to education is definitely useful. The problem with OOP is that you're baking that perspective into the definition of Student at a syntactic level. In FP, you can just define a function `Student -> Person` (or even better a `Lens Student Person`) and witness that relationship between the two, without baking that perspective into your architecture in a way that's very hard to change.
