I don't think they replace each other, FP is a lot more generic in the sense that it applies to all programming but Rx is a good Streams impl except for that AFAIK it can't abstract the return type, so you can't run the Observable to any F<_> j it has it's own opinionated runtime but in FP you would have Stream<F, A>
