I could make the same assertion about "self-described OOP languages" or "self-described procedural languages" with just as much evidence. Once you've done it enough, all programming feels like a pain in the ass. I see FP languages being able to excel at the kind of projects with large, maintainable codebases that evolve over a decade and are shared between dozens of developers. Service oriented architectures serve the same goal -- isolating behavior and state locally, and being explicit about mutation and state changes over time.
