I wouldn't necessarily discount the value of the older maths; I'm taking analysis and abstract algebra as my first classes in a maths masters program; most everything is from the 1800s or early 1900s but is still mind blowingly cool and not necessarily well known on the street. Vitali sets, the Burnside lemma, group actions, all quite fun. And this is before even treating a function space as a vector space or Galois theory.
