Multithreading isn't some magic thing you slap on to go faster. You'll find single-threaded event loops in all sorts of high-performance code, e.g game engines.

Which high performance game engine is single threaded? To my knowledge they're all multithreaded and heavily pipelined.

Parents wrote about the game engine event loop. Not the engine in general.

VS Code is not single-threaded in general. It's event-loop is.
