Functional programming not more productive

Functional programming is not be more productive than imperative programming.

Besides the fact in practical cases, you can hardly do a real application in pure functional programming and how it sometimes complicates things by making you think things in a twisted way, there's a problem with functional programming:

Every time I write something that's actually much faster than having written the same thing in an imperative paradigm, I spend all the time I saved fapping to it.

Is correct.  If you wish to write a program to show a complex logical implication or numerical calculation then it can be much easier translating those mathematical formulae from symbols on a piece of paper to program using a functional then a imperative language.
