Since you’re talking about threads in the context of the BEAM, you might want to give it a deeper look. There are no threads there, at least not OS threads on the developer’s disposal.
I don't have a use case where anything in my toolbox isn't already sufficient enough to solve, it wouldn't be worth while. Maybe if I cared to work at some big place or specifically Ericsson, but there's better things to be doing with my time. There's plenty of problems that can be solved with tools like uv/Python/PyWebView.
