Lisp is good to learn, but because it has "won" in a lot of ways I'm not convinced it's as important as it used to be. Lisp acquired its reputation in a world where a C programmer would pick up Lisp and holy shit dynamic typing, first-class functions, garbage collection, REPL, macros, powerful syntax-aware editors (which C got, but later), atoms, recursion, violent foaming at the mouth and falling down in sheer awe. If it's still your first language after C, sure. But if you learned, say, Python in school, the list comes back to "macros, which you really shouldn't make much use of in the more modern understanding, and a bigger focus on recursion". Less likely to make you pass out in awe.
(Since I find I sometimes piss people off by claiming Lisp is less than the bee's knees, remember, it's because Lisp won in a lot of ways. It blazed a trail that every modern language today has traveled to some extent or other.)
Haskell still has a counter-cultural element because of the fact that Lisp is quite dominant right now and most languages are about empowering the programmer to do anything at any time. The restrictions-based languages are just starting an ascent (currently probably being led in practice by Rust, I think, if it's not already bigger than Haskell it probably will be in less than a year), but it's still pretty early.
