I think this article missed a key element of where ruby is going: developer productivity tools. It is kind of hinted at with static typing, but the real story behind a lot of what happened since ruby 3 was released has been the tools and IDE plugins around it. Static Typing via RBS is also the existing LSP integration + VSCode plugin, the Typeprof plugin which allows scaffolding .rbs files for untyped modules, and the new debugger which will ship with 3.1, finally a core-blessed debugger, but above all, a debugger one can integrate with docker and IDE. I'm expecting more of this in the future, such as a production-ready profiler, better tracing, overall better monitoring.
