So, I'm tempted to conclude that FP is only applicable to situations where user interaction is a small part of the program. For example, for simulations.
I can't confirm that. I've written several I/O-intensive applications in Haskell, including full-blown network servers which arguably do nothing _but_ user interaction, and I haven't run into any problems I couldn't solve. Plus, most of the problems I've ran into were caused by non-strict evaluation rather than the purely functional design per se. The old saw of "right tool for the right job" certainly applies to Haskell too, but given the fact that there are _operating systems_ written in Haskell, I'd say that Haskell's scope is a lot broader than most people would think.
