Having debugged deadlocking threaded code in production, frankly, I prefer async/await style of code, which btw is in Typescript, Java, Python, etc.

For parallelism, there's concepts like python's multiprocessing (which I think does it right) because it's easier to think about parallelism when the OS doesn't constantly pull the rug out from under your state.
