OK I think that's a good and useful point and a motivator for learning FP. Nevertheless because most people continue to perceive things imperatively and because as the article says FP is puzzle like then the author still is probably right when they say that FP will remain unpopular. I like "solving puzzles" but I don't like solving them under pressure. I also don't like deciphering someone else's puzzle when I am in a hurry and when I'm unlikely to never need this piece of code again. So even for people who like puzzles it's often the case that they just need to get something working fast that's reasonably correct. The fact that life is short and that the world changes so rapidly is what makes worse better.
