I think functional programming never took off because the world around us is made of stateful, interacting objects. Pure FP uses a completely different paradigm, so there's a huge impedance mismatch when you try to connect FP programs to the real world or run them on real hardware. I've written my share of Lisp code, but it never seemed to be a good fit for things other than AI and propositional calculus.
