Python has had async for 10 years – why isn't it more popular?

What the article and the comments don't seem to mention is also that the documentation is an outlier on the poor side. Most Python documentation is at least decent. asyncio hides a lot of the complexity behind a tutorial style "just do this" prose, only obliquely mentions the foot guns and gives little guidance on how to actually structure async code.

IME writing an asyncio Python application is a bit like fixing a broken Linux boot. You frantically Google things, the documentation doesn't mention it, and eventually you find a rant on a forgotten Finnish embedded electronics forum where someone has the same problem as you, and is kindly sharing a solution. After 30 mins of C&P of random commands from a stranger on the web, it works, for no reason you can decipher. Thank goodness for the Finns and Google Translate.

I would disagree on the first paragraph, if only to say that the majority of Python stdlib documentation is written in that tutorial style, and I loathe it. It is always a chore to look something in the stdlib up, especially if you're used to the reference documentation for Rust/Go/Ruby/JavaScript.
