OOP mirrors familiar, everyday imperative concepts. FP is much more rigorously mathematical and abstract. The evidence is overwhelming at this point that the average programmer finds the former easier than the latter, despite well over a decade of denial by some of the more vociferous advocates of FP. Those people would do well to emulate DPP's example here and recognize that the long-term success of FP depends on selling to the right audience at the right time and not promoting it as a panacea.
