I tried Googling, but why are Scala and Haskell automatically classified as "academic"?
Because they are inspired by 20th century mathematics rather than 18th century mathematics. This quote from wikipedia explains it:
These developments of the last quarter of the 19th century and the first quarter of 20th century were systematically exposed in Bartel van der Waerden's Moderne algebra, the two-volume monograph published in 1930–1931 that forever changed for the mathematical world the meaning of the word algebra from the theory of equations to the theory of algebraic structures. -- http://en.wikipedia.org/wiki/Abstract_algebra
The academic languages are the ones aware of that change in the meaning of the word algebra. Everyone learns Euler in high school. Nobody learns Mac Lane.
