Suppose you're in a situation where you have to resolve a bug under 15 minutes, or you'll get fired, or maybe your company will go bankrupt. If the codebase if FP based, it is certainly going to be more difficult to quickly find and fix the bug as compared to a codebase written in a simpler language. FP is good for experimenting and playing with, but IMO it is not suitable for anything serious. Rust is also not going to get too far for the same reason I believe.
