If you've taken the time to learn Lisp and it hasn't impressed you even a little bit, you're made of more stubborn stuff than most programmers.
But most of the "non-academic" languages wind up cribbing from the academic languages anyway. For example, Python is very much a Working Man's language, but it pervasively uses not only garbage collection (from Lisp), but also list comprehensions borrowed directly from Haskell!
