When I hear AI being discussed LISP comes up fairly often. In the book "Meta Maths: The Quest for Omega" by Greg Chaitin, he mentions that Kurt Godel's work had a notation that was uncannily similar to LISP code. On the other paw he compares Turing's idea of code as something more akin to machine code.
