Which really does not reflect reality at all. Outside of research/education, and stuff hobbyists are doing, FP typically isn't typically used alone. Some ideas are just borrowed from it and sprinkled onto OO languages to make things a bit nicer. FP has a lot of good ideas, but that doesn't make it reasonable to assume that it's all you need to know, or even the most important thing for you to know.
