I was sad the day I saw Emacs implemented threads before a proper async event loop / futures / etc. Do those first, see what kinds of concurrent code people actually want to write, then write a multithreaded scheduler for that. Instead it’s backwards, now we have hard-to-use concurrency primitives and still shitty UIs.
