Elegant, complex and expressive languages aren't easy to read/debug/rewrite. Having a set of special symbols, arcane syntax and complex abstractions isn't a selling point: the purpose of the language to have maintainable and performant software - not to extend the language itself or showcase its strengths. Nobody would "switch to X"/"Rewrite in X", just because X is better, it has to be substantially better for the specific use-case: like a user would not start learning Lojban just because its much better than English, a specific use-case and pragmatic reasons would need to appear where Lojban-as-tool, not Lojban-as-elegant-expression, will clearly outperform English in its domain(e.g. translating concept to some precise neutral representation), and since these use-cases are quite rare, Lojban would not get as much audience despite its rich constructive capabilities in describing concepts.
