I disagree. I dont think that is what the author was saying at all, not even a little bit: "100% pure functional programing doesn’t work. Even 98% pure functional programming doesn’t work. But if the slider between functional purity and 1980s BASIC-style imperative messiness is kicked down a few notches — say to 85% — then it really does work. ... It’s possible, and a good idea, to develop large parts of a system in purely functional code. But someone has to write the messy parts that interact with the outside world."
