A German design, Russian implementation, and Chinese copy.
Germans have never implemented it. Russians forced them to use the Russian implementation till it crashed.
Russians are running a new system but still influenced by the old one.
Chinese kept the core, but redesigned the system with Capitalix API. The API is not exactly compatible with the core. It’s buggy, but seriously fast. Architectural change is unlikely in near future.
I like the computer language 🙂
